The Firefox 147 release should respect this XDG specification around where files should be positioned within Linux users' home directory. The XDG Base Directory specification lays out where application data files, configuration files, cached assets, and other files and file formats should be positioned within a user's home directory and the XDG environment variables for accessing those locations. To date Firefox has just positioned all files under ~/.mozilla rather than the likes of ~/.config and ~/.local/share. Firefox XDG Base Directory spec bug report Back in September 2004 this bug report was opened to support the FreeDesktop.org XDG Base Directory specification. Merged this morning was the support for this specification and associated commits. Firefox XDG Base Directory spec commit In turn this long-open bug is now closed and Firefox 147 should be the version to finally support the XDG Base Directory specification for jiving more nicely with other Linux apps. 21 Comments Tweet Related News Firefox 145 Binaries Available - Aside From 32-bit Linux Being Removed Firefox 145 Beta Released With 32-bit Linux Support Dropped Firefox Finally Introducing Matroska / MKV Playback Support Firefox Ending 32-bit Linux Support Next Year Firefox 142 Now Available - Allows Browser Extensions/Add-Ons To Use AI LLMs Firefox 141 Release Brings Lower RAM Usage On Linux About The Author Michael Larabel is the principal author of Phoronix.com and founded the site in 2004 with a focus on enriching the Linux hardware experience.
