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)!

Version 124 is no longer supported and does not receive any security updates, making it unsafe to use online.

If you want an older supported version you can install the ESR version (115). If you want something closer to release you can install Developer Edition (126 early beta).

Thanks, I will check them out - I used to have ESR a long time ago...

In the meantime I have installed Brave for this weekly task I need to do.

Also, if you want to choose your own installation folder, start by downloading a full installer. The following article has the details: Custom installation of Firefox on Windows.

Either way, different version of Firefox cannot share the same profile folder, so the older version will need to have its own profile.

Yes, I actually did that initially, but I was rushing and 'guess' - did not click on 'Custom'!

I used to have double installation years ago, I forgot everything!

Thanks for the reminder... that is what I meant and thanks to both of you.
