The web browser Firefox 89.0.1 is now available. The new version of Mozilla's web browser fixes a security issue and several non-security related issues.

Most Firefox installations should receive the update automatically. You can check Menu > Help > About Firefox to run a manual check for the update so that it is installed right now and not at a later point. Firefox includes automatic updates functionality that checks for updates frequently to install them once they are discovered (Mozilla is working on background updates in Firefox for Windows)

The help page that opens lists the installed version of the browser as well.

Firefox 89.0.1 addresses one security issue. The security advisory reveals that the issue has the severity rating of moderate and affects Firefox on Windows devices.

When drawing text onto a canvas with WebRender disabled, an out of bounds read could occur.

 

This bug only affects Firefox on Windows. Other operating systems are unaffected.

Besides the security fix, Firefox 89.0.1 addresses several issues, some of which are operating system specific.

The update addresses the broken scrollbars issue on some GTK themes on Linux, and performance and stability regressions with WebRender on systems running Linux.

On Mac OS X, screen flickering was fixed that happened when pages were scrolled on external monitors.

On Windows, a screen reader issue was resolved that prevented certain screen readers from interacting with Firefox.

Firefox 89.0.1 fixes font related regressions next to that, and the Enterprise policy DisableDeveloperTools, which did not have any effect anymore.

Last but not least, the new release includes updated translations and full support for Spanish (Mexico) localization.

You can check out the entire Firefox 89.0.1 release notes on the official Mozilla website. There you find links to Bugzilla, Mozllla's bug tracking website, in case you want to take a closer look at a bug.

The next major update for Firefox is Firefox 90. It is scheduled to be released on July 13, 2021.
