MOZILLA FIREFOX - how do I reverse the upgrade to 57

FredMcD a répondu
57unexpected

I was on one computer earlier and when it said there was an upgrade I did it, then found out it was changing the appearance, then went to open a tab and found undesired and unauthorized links / "recommendations".

Then I went on my other computer, and it AUTO UPDATES, and I still don't see a button or link to reverse it.

So I go searching on finding out how to reverse the upgrade, and it seem like I need to go take a computer course to do so? And some people have already had problems with portions of the "previous" version that I rely on.

I really do not have time for that right now!

MOZILLA FIREFOX - please provide a simple way to reverse this change that I was not given information to avoid.
