Hello,

We are operating an enterprise legacy system that heavily relies on XSLT 1.0 for its rich text editor and file upload modules.

As you may know, Chromium-based browsers are deprecating XSLT support on November 17, 2026. However, they provide an enterprise policy (XSLTEnabled) to temporarily allow its use until August 2027. We only need to maintain our legacy system until December 17, 2026, before migrating to a new integrated platform.

We are considering using Firefox as an alternative browser for our internal users during this period, but we need to clarify Firefox's roadmap regarding XSLT deprecation.

My questions are: 1. Target Date: Is there a specific target date or Firefox version planned for the complete removal of XSLT 1.0 support? 2. Enterprise Policy: If Firefox plans to remove XSLT before December 2026, will there be an Enterprise Policy provided to temporarily extend its functionality in a corporate environment (similar to Chrome's XSLTEnabled)?

Thank you for your time and assistance.

Firefox 158's announcement page tells me that Firefox 158 has an Ad Blocker. Nice. I'd like to try it. The announcement page tells me to go to "Settings > Browsing". When I open "Settings", there is no "Browsing" option.

I updated my Microsoft office to the latest office 365 desktop version. The install changed something, and any link in an e-mail now gets sent to Edge, rather than Firefox. I checked all the file extensions and made sure they all point to Firefox, but the problem is still there. Any suggestions for what to try next?

under the new nova ui style, settings ui now has a left hand column listing the settings categories available the selected catqgory is highlighted in a light purple color. not a fan. how do I change the color. don't mind collateral damage as not a fan of this color.
