This question already has an answer here:
Currently I am running FF56 on Ubuntu 16.04. Despite the cool new stuff in FF57, I can't update because some extensions I regularly use won't be compatible, and there are no similar compatible extensions available.
But I do want to keep up on security updates. I hate to go back to FF52, but the only option I can see is to downgrade FF56 to FF52esr. The file available from Mozilla for 32-bit en-US is "firefox-52.5.0esr.tar.bz2".
I realize there are other questions that deal with handling installations using this kind of archive, however I was hoping someone could write a procedure for this specific situation, as it may be commonly needed for those wishing to retain FF57 incompatible extensions.
