For anyone interested in running the latest stable release of Firefox on Debian 12 aka "Bookworm", its possible to use the Firefox tarball provided by Mozilla. Steps: 1. Download the Firefox tarball from Mozilla - https://www.mozilla.org/en-CA/firefox/new/ 2. Unpack tarball and store the folder somewhere, i.e on single-user system I keep it in home 3. Create a link somewhere in your PATH to the Firefox executable, i.e ln -s ~/firefox/firefox ~/bin/firefx . Hint: I call the link something different - "firefx" - so as to differentiate this manually installed Firefox from any Firefox (firefox-esr) installed by the Debian package manager. 4. If you use a traditional desktop menu to select and launch your programs, you can create a .desktop file for your new Firefox. I skip this step because I use a dynamic menu/application launcher (rofi/wofi). This is how I do it and it works good! --- Open Source Outer Space => https://www.dwarmstrong.org
