Firefox Community Forum

So I guess my Firefox update to ver. 147 from 146 by its auto update feature, but I realized all the past personal data (ie, history, cookies, passwords, profile, etc) was gone.

I have Mozilla Account (I think it's the same as Firefox Account back in the old days), so my personal data is now retrieved from some device as far as possible, but I lost local personal settings like Shortcuts on the main page on my laptop,p which is the main device to do everything.

I can't help what happened to me, and I will rebuild what I used to be on that day, but I am curious if it's just me, or there is some logic to cause this data loss.

At least once a day since Version 145 dropped Firefox has told me I need to restart to update. When I do, it shows a pop up telling my I am opening an older version of Firefox and need to create a new profile to avoid corrupting my data. Daily, sometimes twice a day I have to go in and switch profiles back to the profile that has all of my book marks. Every computer in our office has this issue now. One of them deleted a profile without prompting, and it is not even in the appdata folder with "deleteme" in front of it. It is just gone. The last update had tabs crash daily. Is there any hope of stopping the second broken update in a row from wasting my time fixing it every day?

have no idea what this topic falls under but getting the update browser error code 99,999 again after restarting the damn computer when it just froze while I went out for 15mins I am updated so have no clue what to do

wish sending a question or replying to the email was easy but even that is b/s also this deny person claims bug fixed but obviously not

Firefox was updated on my computer on 7/23/25. I can no longer access some of my applications. I tried Outlook and everything worked fine. Help me out here, everything was working just fine before the update, and I want to return to a working version. Thanx.

HERE'S HOW I SOLVED THIS "SECURE CONNECTION FAILED" ISSUE:

Kept getting this error when attempting to update Firefox; didn't matter which browser I used; went through the forum postings and tried every this-and-that-and-this-and-that posted there; didn't work; finally --

i opened a $10.00 30-day hotspot account with Xfinity, and the download worked perfectly.

PROBLEM SOLVED.

Never seen this before. I installed v143.0.4 on 10/3. Since it was an extended length of time up to now, I went to check (Image 1 & 2)

I still wasn't convinced (Image 3)

Also, I never opt to "Automatically Install Updates". I don't know how that got selected, but even so, it did not work.

Explanation please?

I have taken the position of never installing updates of firefox in windows 10 because of the following: after EVERY update, within 20 minutes of activity my mouse freezes. Keyboard is inactive. I have no option but to reboot. Windows displays "repair mode" 2 HOURS LATER ! the pc finally boots. This happens after EVERY upgrade. Since I have stopped upgrading, the pc behaves.
