Firefox Community Forum

Yesterday, possibly related to updating to version 148, my profile completely disappaered. My old profiles are not visible under about:profiles, but are present on disk. They can not be imported with firefox -P. How do I get my profile data back?

• OS Version: Microsoft Windows 10 Professional (x64) Version 22H2 (build 19045.6466) • Firefox 149.0 (64-bit) • Thunderbird 140.8.1esr (64-bit)

Have NO idea "which topic best describes my question" from your drop-down list (above), so simply clicked on one.

Restarted my PC; all of my bookmarks disappeared. NOT acceptable. (Or is this just another "improvement" from Firefox . . . ?)

Where did they go; how do I retrieve them?

Really don't want to wait days until there's a response, as I DO USE MY BOOKMARKS ALL OF THE TIME.

Thank you.

I was gifted with the latest upgrade, and all of my passwords and bookmarks have been lost. I signed in with both of my primary emails, and both are acting as if they are new accounts.

This has happened several times in the last 4 months or so, it had never happened prior to that and I've used Firefox for years. It now occurs when I open Firefox after my computer has either been shutdown, or the computer does a restart. I am signed in to my Mozilla account.

with this new version i lost everything i need to get back to an older version and get all my extentions my bookmarks back all my s desktop items that i had linked to firefox are gone i can no longer get face book or anything back to firefox book marks every thing i had with firefox

and

Where do I input my recovery Key to get my account back? I recently had to get a new mother board and hard drive on my laptop. In the process, it wiped out my Firefox. I have reinstalled Firefox and have my previous Recovery Key to get my bookmarks passwords but can not locate where to enter the recovery key to do this. All I can seem to find is how to create a recovery key, not where to enter an already existing recovery key. Please help.

I got a PR_END_OF_FILE_ERROR and cant visit some websites. I followed the correction instructions but now i am severely limited in my browsing. I created a new profile and lost my bookmarks and some important websites. Can i go back to my previous profile? .

I have been a user of Firefox for many, many years (it is my default browser) and as of today I am extremely upset with you. Once again I go to use my favorite browser and all my bookmarks have been removed. THIS IS THE SECOND TIME SINCE THE NEW YEAR 2026.

I spent a great deal of time putting the bookmarks together that hold all the links to clients and their respective sites, along with all the places I have applied to and was about to apply, and today, again, they have all disappeared.

So, give me a reason to keep using your browser? As of this point, I am going to move to another browser and begin setting up all the bookmarks that I remember ... thanks for what seems to have become a HUGE problem with Firefox and blowing away my bookmarks and making me reset everything.

I have used Firefox when everyone told me to move to another because I believed you were the best at protecting my browsing experience and you didn't disappoint. But these last two times you have removed so much of my time I am at a loss as to why I even bother with you now ... besides, you have removed my Dad's obituary link and I'm not sure I will ever trust you again.

A, once, true believer in your ability to protect me.

I am looking to Restore yesterday Firefox have lost all my pin tabs when I opened this morning the browser how can I get my old stuff back? Please help me out. Thanks

The last automatic browser update (147.0.3 (aarch64)) has wiped off all changes I made to bookmarks and passwords from the past year.

How can I go back to a previous version and recover my details?

This browser version is terrible and looks exactly like Microsoft Edge which is not intuitive at all. I don't want to set up multiple personas, Its just me and the one computer?

Please help me. Kerri

I had a catastrophic failure of my desktop computer. They were unable to recover over half my files. My bookmarks in Firefox had links to several critical business pages and I really need to get them back however I have been unable to access them or recover them. Is there any way for these to be recovered if the backup wasn't on? I know its a long shot but I have to ask.

I am at a complete loss on this. A recent firefox update has shifted all my site logins and passwords elsewhere in mystery and impossible to recover nor find them. I tried "Restore bookmarks, passwords and data from an old Firefox profile" but the profile is simply not there and the instructions completely haywire. I have nothing on the profile page. What have you lot done to make this completely unusable for the small person ? I thought I was computer savvy but now firefox is making things unnecessarily invisible and over-complex.

Good morning,

I just made your suggested "reorganisation" of the Firefox Browser with the result that all my hard collation of all my bookmarks, website and passwords are presently gone!!! I can only hope that you have a possibility to recover my datas.

Please advise your instruction to recover my websites, bookmarks etc.

Many thanks in advance.

Hello Mozilla Team,

I'll directly jump into - 12 years of Bookmarks and history are gone after the last update. No warning or anything. Can you help me restore? That's unbelievable.
