Firefox 148.0 released

[Posted February 24, 2026 by jzb]

Version 148 of Firefox has been released. The most notable change in this release is the addition of a "Block AI enhancements" option that allows turning off "new or current AI enhancements in Firefox, or pop-ups about them" with a single toggle.

With this release, Firefox now supports the Trusted Types API to help prevent cross-site scripting attacks as well as the Sanitizer API that provides new methods for HTML manipulation. See the release notes for developers for changes that may affect web developers or those who create Firefox add-ons.

Appreciating the nuance in configuration

While I'm not at all a fan of Firefox's inclusion of additional AI features, I appreciate the nuance of supporting "disable features by default, enable this specific feature" (e.g. translation)", rather than forcing everything off and not giving the option to turn individual things back on.

Yes, I like that too. And presumably as new features are added, if you've disabled "all future AI features" you will be given an opportunity to selectively enable them.
