I am an Ubuntu user and I would like to have an older version of Firefox on my system (to enable TiddlyWiki to write to my file system).
I found in Internet the sequence of steps for installation of older version. However, I would like to go a simple way (without saving archives, unpacking them and so on). Is the a command line way to do that. Something like using
pip? Can I have two version of Firefox on my system?
I am not sure but it seems to me that I need to go in the direction of virtual environments but I do not now how exactly it should be done.
