Firefox 55.x needed - how to?

[vliscony]

My firefox was at 56.x but now I have some app that needs 55.x

I can uninstall via the software manager, but I have not figured out how to install version 55.0. All I find is a tar.bz2 file for 55.0, but no .deb in sight.

In synaptic

Code: Select all

gksudo synaptic

search for firefox and see if there's an old version there; then -
synaptic->Package->Force version.

Or, this is what I use:
https://ftp.mozilla.org/pub/firefox/releases/
The files are archives that you expand into a directory, then make a link to the executable; they're not regular linux/Mint installation files (not .deb) and Mint won't think firefox is installed after you remove your current one.

Using an old version of a browser is an excellent way to get hacked ... one of the most reliable. I don't think you need the latest versions of all you software (if I did I'd run a rolling release) but browsers, yes, you do.

So what I'm wondering is how badly do you jneed that unspecified app?

[vliscony]

yes, that risk concerns me...

My alternative is to run it on a windows box. or to install a windows vm on this machine and run ff55.00 in it, on Windows.

I never worry about it and never have any problems and always run old versions (currently FF47) until forced to update for whatever reason, mostly because each new FF is a little worse than the previous one. I found FF 56 to be almost unusable.
