Diễn đàn hỗ trợ Firefox

Hi I wish to have Firefox 125.0.2 and 124.02 'separate instances', not different profiles...

I already have 125.0.2 installed with various Profiles.

I found a 'few' links and they were quite 'cloudy' and also since Firefox (now) does not have the 'ask you WHERE to' install... I vaguely remember years ago, it was possible.

I do not mid doing tweaking, I also already have backups of profiles, just in case!

Thank you in advance M

PS it seems Mozilla does not want us to install multiple instances (perception)!

Whenever I have Firefox open on Windows 11, my windows key doesn't work. I can assure that its Firefox because whenever I close it, the windows key starts working again. This is really annoying because I normally use the keyboard and having to move my mouse to the bottom just to open the menu gets annoying quick.
