Firefox ESR 91.5.1

Firefox ESR (Extended Support Release) is a version of the popular Mozilla Firefox browser with an extended support period.

The new Firefox policy of updating as often as possible, the release once a month began to lead to problems for users in the browser: glitches of new versions, incompatibility of the necessary add-ons, etc. It was for this that Firefox ESR was launched, which differs from the standard version in three important points:

1. A fresh release is made from the current branch only after a certain period of testing a regular release by all those who use non-ESR releases.
2. The release period is much longer than usual.
3. Only updates covering security holes are released for it.

Thus, we have a stable browser at the output, with a release change periodicity of about a year, which has passed extensive testing and has security updates.

In this form, the browser will be useful in large organizations, such as universities and schools, government organizations and large private companies. During the extended cycle, no new components will be added to Firefox ESR, only fixes for security and stability issues.

The main features of Firefox ESR practically do not differ from the main version of the browser:

• Convenient bookmarks bar.
• Integrated search bar. The number of search engines can be increased by installing the necessary plugins.
• The ability to view and work with multiple sites simultaneously in separate tabs of the same browser window.
• Automatic updates, the size of which is usually no more than a few hundred kilobytes.
• Privacy protection.
• Secure Internet navigation: privacy, protection from viruses, spyware and pop-ups, instant identification of websites and blocking access to the sites of network scammers, dangerous transactions and fakes.
• Full-scale scaling.
• RSS technology support. The ability to create bookmarks.
• A huge selection of extensions and plugins.
