Firefox Community Forum

I've tuned in to Firefox this morning to find that I'm kind of shut out, no access to my usual apps, and required to enact some difficult backing up etc. When I explore, it seems to relate to Windows 10 losing its backup from Microsoft. But I'm running Windows 11, not 10. What's going on? Is this legitimate? If so, why is it complicated and why wasn't it forewarned (by Firefox)?

• 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 thought I used to be able to access browser history from much longer ago, either way I can no longer see any history longer ago than 29/10/2025 is there anyway for me to restore, download or access older history, or has it been permanently deleted? I do still have a back-up of 28/12/2025 but I don't know if or where that contains history. I'm looking for data between 2019-06-01 and 2024-08-21. Weird thing is I remember accessing search history that old before... though I'm not sure how if if it doesn't store it for that long. Any help would be appreciated.

Firefox updated automatically overnight, all bookmarks vanished. Toolbar bookmarks, gone. History information disappeared two weeks ago. Library box is now gone, too! Windows 11. Firefox version 147.0.3 64-bit

My computer went through the process of updating Firebox. Afterwards all my bookmarks are gone. I clicked on Manage Bookmarks...then clicked on Import and Backup...then clicked on Restore which open a File dialog box. What file? Nothing is restore. I want the bookmarks restored.

Hi. I have all the automatic opening of the last session turned on. So for the last two months, when I fired up my PC, all the tabs came back on. That is, until today!

Because I mistakenly clicked "X" when I had private browsing on in other window.

This created error that resulted in blank screen coming in... All my tabs are gone, and they are not in the recent history. How can I bring them back on"? they were just there not 10 minutes ago.

Having seen 2 versions of Firefox on my computer,i tried to delete one version and unfortunately both have gone. is it possible to recover the old version with bookmarks and passwords?

All my bookmarks disappeared and the bookmark button does not work. I have refreshed Firefox - no change. I have uninstalled and reinstalled Firefox but still no restoration of Bookmark button functionality. OS Win10

Attempted to update FF using the 140.2.0esr.msi file. During install it asked for a location of bookmarks (seemed off, like a new install) so the process was stopped. All FF profile files appeared to have been untouched based on their dates. So the following directories: \AppData\Local\Mozilla\Firefox\Profiles\oeg1ubpo.default-esr \AppData\Roaming\Mozilla\Firefox\Profiles\oeg1ubpo.default-esr where both copied to a secondary directory as a safety precaution. Install was restarted and it appears to have again installed a new version with no bookmarks, extensions or password DB carried forward from the previous install, which is not what I wanted.

Can this be corrected, by moving the copied profile back in.

Thanks, Brian
