Firefox 55 ? WAIT !!!

Hi all,

You might want to back up your profile on Firefox 54 before updating to 55. Once you do, your profile will not work the same on lower versions, ever again. For Android users, there is an add-on that works perfectly, as I did a backup, encrypted it, password protected, and saved to Drive folder, along with a copy of Firefox 54. You know, just in case. You could always use a lower, less safe, version without your current profile too.

Here is a tutorial and link included for the add-on to make a profile backup on non-rooted Android devices. It's good to have a backup anyways, I should know, because I accidentally nuked mine a few years back.
