Firefox is crashing like crazy. It happens randomly. All it says in the crash is that the crashing thread(0) aka MainThread stopped working

My latest crash reports:

I am sorry that my letter has caused you trouble but I have to ask you for help to solve the problem I was facing. I forget to save my account Password when I uninstalled the Firefox browser and I didn’t log in to my account at the time.But I’m in hurry and need it too.Can you help me get it back?Thank yo very much! And the website is pog.org

Apparently Firefox did an update (version 136.0.4) in the background while I was using Firefox on March 27. At some point I wanted to save a page to my bookmarks and realized all my bookmarks were missing. I had just used bookmarks earlier, so it had to have been an update. This happened to me before back in January 2025. I was without my bookmarks for several weeks when all of a sudden they showed up again.

I cannot use the instructions to go back to a previous profile, as the two options showing do not have my bookmarks, bookmark toolbar or customized Firefox homepage. I also cannot import my saved bookmarks to get them back. I get an error message when I attempt to do that option.

This is very frustrating, as I use my bookmarks, toolbar and customized homepage EVERY day. I have all my important links saved to bookmarks. Firefox developers need to find out why an update removes bookmarks, as this seems to be an ongoing issue with me. I've used Firefox for over 17+ years and never had bookmarks removed after an update before, so something in an update is causing this issue.

I have no idea at this point IF everything will return to normal in a few weeks like it did back in January. So right now I am without all my bookmarks. Please get this ongoing issue resolved, it's a royal pain. I need those bookmarks to maintain my daily routine for accessing financials, medical websites, etc.

Thanks for any help you can give me at this point. This is the second time it has happened.

I had to quit Firefox this morning because of a problem with my proxy and when it reopened it had updated to Firefox 139. In the process, I lost my entire browsing history and all open tabs from my previous session. Although in settings I have "Open previous windows and tabs" selected always, when Firefox restarted the browsing history was empty and "Restore previous session" was not an option under history, nor were "Recently closed tabs" or "Recently closed windows." I cannot locate any backup files in the Firefox library on my computer (MacBook Air running Ventura 13.7.5). I really need to be able to restore the previous session, please let me know if this is possible.

Is there any program to recover the profile? Using Firefox and LibreWolf, I find that when I reinstall the program, the saved profile from a previous version isn't recognized by Firefox or LibreWolf. There's no way to recover the entire profile without problems; it can only be achieved by copying a few files from the old profile to the new one.

For a long time, it has been impossible for both browsers to transfer/copy a previous profile to the new installation, for example, from version 137 to version 139.

Desde hace mucho en ambos navegadores es imposible trasladar/copiar un perfil anterior a la nueva instalación, por ejemplo de la versión 137 a la versión 139

I am experiencing an issue with the Keeper browser extension on Mozilla Firefox. Despite configuring all related settings appropriately, the extension consistently locks out every time I close the browser.

To troubleshoot, I have:

Verified that the extension is enabled and fully allowed in Firefox’s Extension settings.

Ensured that Keeper is whitelisted in every possible relevant setting within the browser.

Checked that the "stay logged in" or persistent session options are correctly set within Keeper’s own configuration.

Confirmed that no conflicting privacy settings or third-party add-ons are interfering with the extension's functionality.

Despite these measures, the extension does not retain its logged-in state upon browser closure. This behavior suggests a persistent session issue not aligned with the user-side configuration.

I would appreciate guidance on how to resolve this.

For several weeks the Dashlane addon has been failing to function and customer service has failed to respond to all messages. Signing on was a simple matter of entering user email address, then the password. For several weeks entering user email address opens a required instruction to enter a code number set instead of the password, saying the code was sent to the email address. The email number perpetually never arrives. Neither do responses to email notices/inquires directly sent to Dashlane. Has Elon Musk fired everybody at Dashlane or is Trump in charge?

Over the past couple of days, Firefox has been crashing almost constantly, with my MacBook sometimes also crashing/restarting. Both Firebox and my MacBook are up to date. I've also used troubleshoot mode and turned off my extensions, which seemed to lower the number of crashes, but it still crashes often. It might not be a problem with Firefox itself and be my laptop though.

If there's a way to resolve this, I'd super appreciate it.
