Firefox rel 89.0 and 89.02 are not working for me.

more options

My first Firefox version was 1.0 several decades ago. I have used it with great success until 89.0 then everything went sour. So I tried to go back to 88 but it would not let me use my previous PROFILE. All it allowed was to CREATE A NEW ONE. It gives you only one option, "EXIT or CREATE A NEW ONE". EXIT 'stops' future installation, CREATE A NEW ONE and you lose EVERYTHING. I don't remember these issues in the 'old days' of reverting back if one had problems with a new version. I found my old profiles but I do not know to USE my last one. I was surviving with rel 88 but it crashed 3-5 times a day and today, finally went hard down and would not run. It then gave me 89.0. Terrible. Then here comes 89.02 AND IT CRASHES WORSE THAN 89.0. Right now my Firefox is worthless so I am now using EDGE which I 'REALLY' dislike but it WORKS unlike Firefox. What I WANT to do is go to an older version until they get their act together and USE one my OLD PROFILES to save everything.

DOES ANYONE KNOW HOW TO USE A PREVIOUS VERSION, THEN SELECT A PROFILE TO "GO BACK"?

Since Firefox 67, installing an older version requires creating a new profile.

In your new profile, open the about:profiles page. Then "Open Folder" on the root directories of your new profile and your old one.

You can copy selected files from old to new (while Firefox is not running) per this article:

Recovering important data from an old profile

Since your old profile was already unstable, limit what you copy over. For example, try copying over only:

Bookmarks and history:

  • places.sqlite
  • favicons.sqlite

If you use Firefox's built-in password manager:

  • logins.json
  • key4.db

Make sure not to copy new over old or much unhappiness will ensue.

Is Firefox stable with that data migrated?

THAT WAS AMAZING.......................THANK YOU, THANK YOU, THANK YOU........................... We seemed to have gone from rel 89.0 to rel 90.0b12 in a very short time. Have you found this release stable? Rel 89.0 was crashing several times a day. One of the things I like about FIREFOX since release 01 is it has been stable and NEW 'wheeze bang' changes are slow in coming and eliminates us constantly have to get accustomed to Firefox's changes, which gives us more production time. When this happens, why is "going back" so difficult and unknown until "They get their act together"?

Again, 'you have made my day..'. Patrick Reeves.

I hoped when we got off release 89.0 Firefox would stabilize. I restored to my most recent version and for a day it was fine. Today, it has gone down 3-4 times with CRASHING my TAB connected to YAHOO Email. Then I noticed we jumped from rel 89.0 to "90.0b12".

It is not my Dell as Edge is a crappy browser as is Chrome but they appear to be the only browser that can stay up. Is it just ME? If not, can we expect anything from Mozilla soon?

Thanks

The b in the version number refers to the beta test series. The only reason to get a Firefox 90 beta would be an auto-update from an earlier beta. Maybe something you installed somewhere along the line was a beta?
