Solving the performance problem

If an application is unstable in safe mode, then the problem lies not in the settings, extensions or theme, but in something else, for example, in the computer hardware. If problems do not arise, Mozilla works stably and quickly, you should turn off the theme and some add-ons.

When you're working in a private window, Firefox doesn't record your web surfing data. This applies to any tabs that are already open or will be opened in this window. There are exceptions for the private window - downloadable files and bookmarks. The window also doesn't let you forget that Firefox itself can't stop those who might be snooping on your Internet connections (including your ISP) to find out what websites you visit. To solve this problem, you will need Tor Browser.

3. Firefox Add-ons

Firefox has add-ons that add new options or expand existing functionality. Add-ons include plugins, such as Adobe Flash , And extensions, such as NoScript. In this section, we'll show you how to disable potentially harmful plugins, and then demonstrate several useful add-ons to enhance your privacy, including:

You can agree by clicking the button [Allow...] in the top right corner of the browser window as shown in the image below. Nevertheless, We recommend turning off Flash completely.

Image 6: Firefox warns about Flash material

3.2. HTTPS Everywhere

HTTPS Everywhere – addition which helps Firefox connect securely to websites that support encryption.

When you access a site at an address starting with "http://" (for example, http://www.amazon.com), your connection is not encrypted. Information you send to and receive from the website may be viewed by anyone with the ability to monitor your online traffic. For example, your (ISP) and many surveillance platforms.

When the address begins with "https://" (for example, https://www.amazon.com), your connection is encrypted. It will be extremely difficult for strangers to intercept the data you send and receive. Unfortunately, even sites that support https, often make mistakes by redirecting visitors to the right addresses. This problem is solved HTTPS Everywhere.

U HTTPS Everywhere there is a list of websites that support https, and automatically requests an encrypted connection for these websites, even if you click on a link starting with http(or entered such an address into the browser line).

to install HTTPS Everywhere, follow the steps:

Step 1. Select paragraph [Add-ons] in the browser menu, as shown in the illustration below.

Step 2. Dial Name

Image 2. Search HTTPS Everywhere

Step 3. Click [Install] Near HTTPS Everywhere.

The installation of HTTPS Everywhere is complete. When you try to visit one of the websites included in this add-on, if that website supports https, your connection will be automatically encrypted.

Note. When HTTPS Everywhere works, you still You will see "https://" in your browser's address bar. If it doesn't, your connection is not encrypted.

3.3. Privacy Badger

3.5. NoScript

When you visit a website, your browser automatically downloads the content of the site's pages. In addition to text and images, this often includes scripts, small programs that run inside the browser. NoScript – addition For Firefox, which prevents the browser from running such programs without your permission.

Basically, these scripts are harmless. Their task is to increase the interactivity of web pages. However, some are dangerous, while others know how to collect information about your online activities; these are the so-called third party trackers .

Unfortunately, NoScript is not able to automatically determine which scripts are safe and which are not. If you first select the total blocking option ( Block Scripts Globally), many sites will not display correctly. On the other hand, adding different sites to White list, you will gradually bring the situation back to normal and at the same time be protected from potentially harmful content on the network.

To install NoScript, follow the steps:

Step 1. Select [Add-ons] in the browser menu, as shown in the illustration below:

Image 1. Firefox Add-ons

Step 2. Dial Name V search bar in the Firefox Add-ons window.

Image 2. Search NoScript

Step 3. Click button [Install] next to NoScript.

Image 3. Installing NoScript

Step 4. Click [Restart now] to restart the Firefox browser and complete the NoScript installation.

Step 5. Make sure the NoScript add-on is installed correctly. To do this, in the Firefox menu, select items [Add-ons > Extensions]. The list of add-ons should also include NoScript.

Image 5. NoScript add-on installed

Your browser now supports NoScript and can block malicious code if it appears on your computer.

NoScript may seem a bit inconvenient at first (sites you're used to visiting will be garbled), but you'll quickly be rewarded by automatically blocking annoying ads, pop-ups, and malicious code embedded in website pages.

NoScript runs silently in the background. When the add-on detects the presence JavaScript elements, Adobe Flash or other scripts, these elements are blocked, and an information bar appears at the bottom of Firefox. NoScript tells you what object it's about we're talking about(for example, advertising or pop-up window) and which script is blocked in the system. However, because NoScript does not differentiate between malicious and benign code, some important parts of the site (such as the toolbar) may not be visible.

Image 6. NoScript Dropdown Menu

Some websites display elements (including scripts) from other sites. For example, sites like www.twitter.com contain scripts from two sources (twitter.com and twimg.com). To unblock scripts in such situations, try choose option Temporarily allow[site-name] (in in this example– Temporarily allow twitter.com). If it doesn’t work right away, then through trial and error you can get the main sites with the information you need to look normal. For example, for Twitter to work, you need choose options Temporarily allow twitter.com And Temporarily allow twimg.com. If you frequently visit a particular site and trust its content, select option Allow [website-name]. In this case, NoScript will consider the site trusted without a time limit.

Step 6. You can continue configuring NoScript permissions, pressing button [Settings] next to NoScript in the list of extensions (or choosing paragraph [Settings] in the NoScript drop-down menu in your browser).

Image 7. NoScript settings

Note. Recently a vulnerability was discovered in NoScript. We still recommend NoScript because this vulnerability not dangerous as long as you Also did not install a separate (initially malicious) add-on. We strongly advise you to carefully study add-ons before installing and remove any add-ons that you do not need or have doubts about.

4. Portable Firefox

4.1. Differences between installable and portable versions of Firefox

The portable version of the program cannot be installed on your computer. Her very presence may not leave any traces. But in general portable programs as safe as yours external devices, USB flash drives and gadgets. Risk of infection by viruses, spyware and other things malicious code is saved.

FAQ

Question. Why are there so many different add-ons needed to protect against malicious websites? For example, if NoScript protects against dangerous scripts, why other add-ons that work in much the same way?

Answer. Often good advice is to use several tools to solve a particular security problem (except for antiviruses, since these programs tend to conflict with each other). Firefox add-ons are very useful different technologies to protect your browser from threats. For example, NoScript blocks all scripts from unfamiliar sites, but the user can exclude a frequently visited site from being suspicious - and, if he makes a mistake, be vulnerable to a number of threats. The user can also temporarily allow an unfamiliar site to load scripts if they are necessary for the page to display correctly.

Want to further verify the site's authenticity before making a purchase? Click on a site icon to instantly identify it. Click again to get more information: how many times have you visited this site, whether your passwords have been saved. Check suspicious sites, avoid fakes, and make sure the site is what it claims to be.

Content Security Policy
Firefox's Content Security Policy is designed to prevent cross-site scripting attacks by providing a mechanism for sites to explicitly tell the browser what content is legitimate. The browser can ignore any content not approved by the site, which increases your security.

Customizable security options
Control the level of thoroughness with which Firefox scans sites. You can even create exceptions for sites that don't need to be fully scanned. Configure settings for saving passwords, cookies, downloading images, and installing add-ons for complete control over your online experience.

Parental control
Use options parental controls, entered by you in Windows 7 - they will stop unwanted downloads and much more.

Secure Updates
Firefox uses a secure connection before installing or updating third-party add-ons software and wallpaper.

Detecting outdated plugins
Plugins are small components third party applications, created by companies such as Adobe Systems or Apple, and making it possible to run videos, animations and games. Outdated versions plugins can be a big security hole, so we've created a lightweight tool to help you keep them in check. current state. Check your plugins.

Sometimes you need to surf the Internet secretly, leaving no trace. If private browsing mode is turned on, then after your journey, others will not find a single trace of web surfing after you. You can quickly enter and exit private browsing mode, so you can easily go back to what you were doing before as if nothing happened (you can also work in private browsing mode all the time). This is especially useful if you work with your bank on shared computer or checking your email in an Internet cafe.

Integration with antivirus
Firefox works well with your Windows antivirus. When you upload a file, your antivirus program automatically scans it, protecting you from viruses and malware that might otherwise attack your computer.

Fraud protection
Securely conduct your shopping and business online. Firefox updates its lists of fake websites every half hour, so if you try to visit a fraudulent site that imitates a site you trust (like your bank), you'll be stopped by a big warning message.

Erasing recent history
Erase all your personal data or just your activities from the last few hours with a few clicks. You have complete control over what is deleted, and at your direction, your information will be erased - whether on your computer or the computer at your local library. It is so simple.

Protection from malicious sites
Firefox protects you from viruses, worms, Trojan horses, and spyware. If you accidentally end up on a site that attacks users, Firefox will warn you that you should not visit this site and tell you why the site is unsafe.

Surveillance protection
Many websites track your online activities and sell this data to advertisers. If this makes you uncomfortable, Firefox allows you to tell sites that you don't want them to collect data about your online behavior and want to keep where you go private.

Forget about this site
Do you regret visiting a certain website? The "Forget About This Site" feature will help you remove all traces of your presence on this site from your browser - quickly and cleanly!

Securing website connections
Firefox prevents attackers from intercepting sensitive data by automatically establishing a secure connection to websites that offer a connection to a secure https server.

Firefox will automatically notify you when you quit new version, so you can be sure your browser is always up to date with the latest security patches.

Many computer users are familiar with what safe mode is. operating system Windows. This is a special type of computer boot, in which the OS starts only with the necessary minimum set of services and drivers, thanks to which the user can diagnose errors that occur in the operation of the device.

Developers are adopting the same experience. modern browsers– recently we have the opportunity to enable FireFox safe mode, which ignores all user changes made to the browser, and also disables extensions and themes. My story today will be devoted to this very mode and how to enable it to troubleshoot problems with the browser.

Important! The troubleshooting process can take a very long time, so it is recommended to use the function, which will reset the browser to standard condition, without deleting the user’s personal data, such as , etc.

Launching the browser

There are several ways you can enable Safe Mode in Mozilla. The first of them is suitable if the browser works, but is not stable, and the second is for those situations when Mozilla does not start at all.

1. To open the browser using the first method you will need:
2. Launch Firefox and open the main menu by clicking on the corresponding button on the toolbar.
3. Click on the button with the image of a question mark.
4. Select the item “Restart without add-ons”, and then confirm the operation in two pop-up windows by sequentially clicking “Restart and “Start Firefox in Safe Mode” (the content of the inscriptions may differ depending on the version of the program, but the essence is the same).

The second way to turn on the browser in this mode is somewhat simpler: you just need to double-click on the browser icon on the desktop with the left mouse button, while holding down Shift key on keyboard.

Diagnostics

Once Firefox Safe Mode has been enabled, you will need to test the browser to see if the error now occurs.

If the browser works stably, then the problem lies in one of the installed extensions. If not, then the problem is related to the browser settings, and resetting the settings, which I wrote about at the very beginning of the article, will help you.

To reset:

1. Go to the same menu from where you launched Safe Mode in Mozilla Firefox.
2. But select "Problem Solving Information".
3. On the page that opens, click on the “Reset Firefox” button, after which the browser will restart with default settings.

I hope this information about Safe Mode and factory reset options will help you identify and fix the issue that is causing your browser to not function as normal. First of all, I would recommend just checking installed themes design and expansion.

No Internet user is immune from problems in the browser. As a rule, they arise at the most inopportune moment, and make everyone, especially inexperienced users, very nervous. However, when such an unpleasant surprise arises with a web browser, you can get away with little loss, even if you lack experience or knowledge.

As an example I will give Mozilla browser, and for good reason, because it is deservedly popular among Internet users from all over the world. So, if there is a problem with Mozilla, the smartest thing you can do is to activate firefox safe mode. What it is, how to enable and disable it, you will find out below.

What is Safe Mode

The term “Safe Mode” means a special mode of operation in the browser that can be used to solve problems in the web browser. It helps restore some parameters, change settings, disable extensions (, visual bookmarks etc.), which are a potential cause of problems.

In this browser mode, it is easier for the user to find the source of the problem and eliminate it.

How to enable safe mode

• To enable safe mode in firefox, you need to perform a few simple steps, namely:
• There are several options for starting Safe Mode. Standard means that you need to go to the start menu and click on the “Run” line. By the way, for those who like to use hot keys: if you simultaneously hold down the “Win ​​+ R” combination, the result will be the same;
• then a new window will appear, in the input line of which you need to write the same as in the screenshot below and click . Ready!

After you have launched Safe Mode, a window with the settings that you see in the screenshot should appear.

Let's briefly go through some of them: the line “Disable all add-ons” means that Mozilla will function as usual for you, but its extensions will be disabled. Don't be afraid, you won't be able to do this by accident.

The “Replace your bookmarks...” option means that all previously opened bookmarks will be deleted and replaced by the browser with others that are more preferable to it. As for the “Restore set...” option, if you check it, everything search plugins default settings will be restored immediately.

How to exit safe mode

Disabling safe mode in firefox is very simple: you need to close the copy of Firefox running in safe mode and click on the browser shortcut to launch it as you normally would.

Safe mode is undoubtedly important, because not a single computer is immune from problems with the browser. However, now you don’t have to worry if such a problem happened to you, because there is a solution, and it’s absolutely simple!
