Browser extensions that will keep you safe online

You can also increase the level of security and data protection of your familiar browser. Our tips for Firefox will help you do this easily and simply.

Network Security with Mozilla browser

Along with the additions presented on the left strip, NoScript also belongs to the most important security extensions for Firefox. With NoScript, you decide for yourself, what scripts should the site execute?, and which ones are not. This way you not only block malicious code, but you also prevent major advertising networks and other trackers from tracking your behavior on the World Wide Web.

NoScript first blocks all scripts on the visited web page by default. It means, that you will have to put your hand in and allow scripts from secure sources. To do this, click on the NoScript icon in the upper right corner and select, for example, ‘Allow ‘.

Regular cleaning of the log

Keep your privacy. If desired, Firefox completely ‘forgets’ about visiting certain websites

Firefox offers various ways to delete the search history in the browser log. The first is the keyboard shortcut ‘Ctrl Shift Delete’, to open the ‘Delete Recent History’ window. Select from the list, for example, ‘For the last hour’ and such ‘Details’, as a ‘Log of visits and downloads’, which you want to delete.

The second option is to delete only data about individual sites visited. To do this, press the ‘Alt’ key and open the ‘Log’ window Show the entire log’. Find the entry with the corresponding site and right-click on it. Select ‘Forget about this site’ from the menu.

Viewing error reports

If an error occurs, Firefox sends the corresponding report to Mozilla. What exactly does it contain, you can find out only in a roundabout way: enter ‘about:crashes’ in the browser’s address bar, to view the reports. Click on one of the links, to open the corresponding error report.

Stop autoloading plugins

For several years, Firefox has been using a feature called ‘Click to Play’ to prevent plugins with vulnerabilities from automatically launching, such as Flash. This setting is carefully hidden in the extensive Mozilla browser configurations.

Type ‘about:config’ in the address bar, confirm the security warning that appears and find the item ‘plugins.click_to_play’. Make sure, that its value is set to ‘true’.

Activate TLS 1.3

Modern encryption. In one step, you can activate both TLS 1.2, and the new version 1.3

The Transport Layer Security (TLS) protocol is required for a secure connection. Version 1.2 is currently in effect., but version 1.3 is already ready to launch. By default, the latter is not activated in Firefox yet.

But this can be easily fixed: you just need to enter ‘about:config’ in the address bar and find securitytls.version.max. Double-click on the entry with the mouse and change the value to ‘4′. Then call up the page and check the entry in ‘TLS 1.3′. The value must be set to ‘Yes’.

Block referrers

Suppress referrers. This setting prevents the creation of a site visit log

The version of the popular browser 53 that appeared this year gave Mozilla Firefox the ability to maintain control over referrers. The referrer informs the visited site that, what other address does the user come from?

To do this, type ‘about:config’ without quotes in the address bar and find the setting ‘network-http.referrer. userControlPolicy’. Double-click on the parameter that appears in the list and change the value to ‘0′, to block all referrers. The value ‘1′ implies the resolution of referrers within the same domain. By default, the value is set to ‘3′.

HTTPS Everywhere: Encrypted site browsing

There are already quite a few sites, offering encryption of their content using HTTPS. In this case, no one can track your interaction with this site.

Unfortunately, this encryption is not always enabled by default, or there is no automatic forwarding with an unencrypted version. The HTTPS Everywhere extension guarantees, that you will always go to the encrypted version of the site.

uBlock Origin: Stop malicious applications

An ad blocker can help protect the system, because it not only blocks advertising services, but also, eg, will be able to prevent hidden downloads. You can accidentally upload malicious files even on trusted sites through infected banners.

The uBlock Origin program not only works faster, what is the competitor of Adblock Plus, but it also provides more functions for logging and filtering settings.

Disconnect: Block online trackers

Disconnect is a good addition to such ad blockers, like uBlock Origin. This add-on prevents tracking and analyzing site browsing preferences.

Besides, it visually visualizes, which trackers work on the site and are blocked by the Disconnect program. The add-on can block ads, sites, performing the analysis, social networks and unwanted third-party content.
