I had to do a refresh of Firefox to its default settings and have the copy of the old data folder sitting on my desktop. How do I restore it back to the state it was before doing the refresh ? Does this also restore the automatic login for sites where I had checked the "Remember Me" button on my initial login?

A couple of weeks ago all of my bookmarks disappeared from my profile. The toolbar is empty and when I click manage bookmarks, the entire interface is blank. When I attempt to do the restoration method suggested in the firefox guide, nothing happens when I click the restore button from the drop down. I tried logging out and logging back in, but that didnt help unfortunately. Any suggestions or help is greatly appreciated.

Hello There,

Since your upgrade to the new version of 154, Having a huge problems. Couldn't log in to various accounts. The most problematic one is to getting in Costco, Etsy and Ebay. Etsy and Ebay has been fixed after a week but Costco one is not. We can't log in and if it allows somehow to login then can't check out. It sits there and comes back to the same page. Won't move forward to the payment page at all. To make it from bad, worse to worst - this morning my wife uninstalled the Firefox and installed it back. That's where all the problems started. Now we lost all the "bookmark tabs, login and everything". We are exhausted and very angry. There's no help line to pick up the phone and get a quick help. So please send a suggestion list to recover the old version or at least all the old bookmark and log in from last 20 years. It'll be highly and hugely appreciated. Thank you.

Michael

P.S: We are also very old folks. Do know much about IT, so please educate and or guide as like a 10 years old.

Profile/session doesn't ever save/load

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

Critical bug in Firefox Local Backup feature: Infinite profile creation loop and extraction failure on a fresh OS installation

Hello, I am writing to report a critical flaw in the new Firefox Local Backup mechanism (HTML-based container). After formatting my PC and installing a fresh copy of Windows 10/11, I attempted to restore my 10 years of browser history using a valid backup file (.html, ~102 MB) created by Firefox 153.0.4.

Although the password was correct (the UI immediately rejected incorrect ones), the restore process completely failed and entered a destructive loop. Instead of extracting the data, Firefox started infinitely creating hundreds of empty profile folders in %AppData%\Roaming\Mozilla\Firefox\Profiles without throwing a visible error to the user, completely messing up the profiles.ini file.

What had to be done to recover the data: Since standard unarchivers (7-Zip) and tools like Windows certutil couldn’t parse the hybrid HTML/Base64 container, we had to reverse-engineer the recovery process using the internal Firefox source modules (PreferencesBackupResource.sys.mjs and SessionStoreBackupResource.sys.mjs from omni.ja).

We had to write a custom Node.js script to:

  1. 1 Parse the specific block-by-block Base64 encoding used by Mozilla inside the HTML wrapper.
  2. 2 Manually decrypt the raw binary data using the backup password.
  3. 3 Extract places.sqlite, logins.json, key4.db, and sessionstore.jsonlz4 manually.
  4. 4 Manually inject these files into a freshly registered profile.

The Bug Core: The built-in extractor in Firefox fails on fresh OS/browser installations due to path/profile synchronization errors, causing a crash loop that generates endless ghost profiles.

Please review the block-by-block extraction logic and add strict exception handling to the Local Backup UI so it doesn't break the profile directory when a routine error occurs.

Thank you.

I was reinstalling my windows and created a backup from my old firefox into my usb drive. My backup failed and coudn't be restored, I'm confident that I use the correct password, tried to copy the file from usb drive into my laptop and select it from there but the result is the same, if you guys would be so kind as to guide me on how to restore my backup, since my password and everything is in there. I didn't create another backup since I believe that this one would succeed. Thank you in advance.e

So my friend uses firefox (not signed it) & called me over to ask where it's tab groups went. I come over to look & they're just gone. I look to see if I can save new ones, can't, so I update firefox to see if the issue is that perhaps. It brings the ability back, but the previously saved & closed tab groups are still gone. Going to the previous/default(?) profile thing didn't work, so we're not sure what to do. Still looking to see if I can salvage them from history or just find them but Twitter & Tumblr can be hell to look through, especially twitter.

Also I don't know what topic this would fall under, so the topic thingy may be incorrect.
