Mozilla is now rolling out Firefox 148.0 to users in the Release Channel. The latest feature update arrives with the promised AI controls that allow you to get rid of AI-powered experiences with a single click or customize them to your liking. There are also improvements to Firefox Backup on Windows 11, fixes for image drag-and-drop, security patches, and more. Here are the release notes:
- Added an AI Controls section to Settings for managing AI-enhanced features.
- Firefox now has improved support for screen readers accessing mathematical formulas embedded in PDFs.
- Remote improvements are now decoupled from telemetry requirements in Firefox Settings. You can now opt into receiving remote browser changes even if you have opted out of sharing telemetry or participating in our experimental studies.
- Firefox Backup is now available on Windows 10 to users who also use the Clear history when Firefox closes capability. Backups will not include any data that is set to be cleared when Firefox is closed.
- The following languages are now available for translation: Translation into and from Traditional Chinese. Translation into Vietnamese.
- New Tab wallpapers will now appear on new container tabs as well as new default tabs.
Here is what was fixed:
