Firefox 135.0.1: important security update and bug fixes

[harlan4096]

Mozilla plans to release a point update for its Firefox web browser later today to address security issues and fix several non-security issues in the open source web browser.

Firefox 135.0.1 comes about two weeks after the release of the last major Firefox version, Firefox 135, on February 5, 2025. The security update will be pushed automatically to most Firefox installations over time. Firefox users may speed up the installation by running manual update checks from within the browser after release.

Mozilla lists four non-security changes in the release notes. The new release fixes the following issues:

• An issue with drop-down menus on certain websites that use "certain mousemove event behavior".
  
• Fixed a scrolling issue that caused anchor tags in some situations to go the wrong location on a webpage.
  
• Addressed an issue that caused Firefox's functionality to restore closed windows or tabs to stop working when executed via the History menu after updates of the browser.
  
• Fixed an issue that displayed an overly large icon for custom search engines that were added to Firefox by the user.
