~/.mozilla/firefox/<profile> is a mish-mash of data, config, and cache. It's not simple to unravel that.
Beyond that, it would be a breaking change, and that requires more caution.
The fun part is, at least since Win95, games were supposed to store their data in the My documents directory. The only game I remember actually going with this was Max Payne, everyone else was just dumping everything in the directory with the exe.
Then Vista came out and those who cared, were scrambling to update their games. The rest just went - shrug eh, run in compatibility mode.
I thought this was the best thing they did. Each user would have their documents (let call it your stuff) separate from another user.
If you share a PC with someone then you would know how this was a good thing.
Even if you don’t share your PC with anyone, you don’t want your nephew to miss up your saves when he comes in the summer and his mom wants you to allow him to play.
Windows's dedicated Saved Gamed folder is within the same user-specific directories that Documents and AppData are in, and would still allow for game saves to be user-specific.
Well, the user is complaining about where it's installed on Linux, not Windows.
It's in the home directory. On Linux, most applications split data between a cache, config and local directories. But for Firefox everything is in one.
Personally, I don't mind it. It makes transferring my Firefox setup between distros easy.
