I started using the firefox nightlies a while ago. I would get updates for both versions 4 (Minefield) and 3.7 (Namoroka). Now I want to keep version 4 nightly, but replace the 3.7 nightly with 3.6 stable. I've already removed the 3.7 nightly, but can't figure how to install 3.6 stable (systemwide). Trying to install it using apt-get starts downloading the nightly again. Where do I need to make the necessary changes?
Edit for further clarification:
Installing version 3.6 stable is not a problem. Adding the mozilla ppa is not a problem either. Getting version 4 nightlies is, likewise, not a problem. Installing and running both verstions simultaneously does not cause a profile overlap -- they each have their individual profiles. I have no problems with profiles whatsoever.
What is the problem then? This -> After you add the mozilla ppa, you also start getting the 3.7 nightlies. So? The process overwrites the stable version of 3.6 with a nightly of 3.7 -- this is what I do not want.
Temporary solution that I have -> Before installing updates everyday, I deselect the 3.7 updates, which keeps the 3.6 intact. I just don't want to have to do this. I want to stop getting updates for 3.7 nightly.
It isn't a big thing at all. I'll probably just have to uncheck some box somewhere, or make a little change to some config file.
But thanks to everyone trying to help. It is much appreciated.
