I'm new to Ubuntu. (14.04)
Firefox comes default as version 31.x, but I need to use 29.0.1.
I've tried following multiple instructions, whereby copying an old firefox (old v29) to the usr/bin directory after unzippping it, thus overwriting the default version (v31). I can't seem to get everything working though.
The default version (v31) and old version (v29) run side by side, but opening the profile manager via the command line (firefox -p) just opens it via the new version (v31).
I need to completely remove the new version (v31) of firefox and just have the old version (v29), which I can then access the profile manager from the command line (so it's all v29).
Removing the new firefox installed by default (v31) via sudo apt-get remove firefox will stop 'firefox' being accessable in the terminal, despite the old version (v29) existing in usr/bin
I'm very confused and need some guidance.
