My FireFox was updated to version 153 and all of my bookmarks are gone. I tried to restore them in Manage Bookmarks. But when i click on 'Import and Backup', then 'Restore', then click on 'choose file' nothing happens. I navigated to the directory "bookmarkbackups" and I can see several backups, one dated 08/06/2026. But how do I get Manage Bookmarks to see that file?

I tried to bookmark a current tab and it does not show up under Bookmarks. why can't I set a new bookmark? Are these issues related?

I'm on Windows 10.

For the Troubleshooting data, I manually open about:support and clicked on 'Copy text to Clipboard'. Then pasted that into the box below.

I didn't know I need to keep a device on if I want to sync my old data. I read it thoroughly. This is annoying, I don't want to lose my Sync data from this because I didn't know. How do you guys retain your Sync data if I were to reset my password? My computer just got fixed and I don't like this greeting of where all my data like history and bookmarks flushed down because I wasn't signed-in in a device nor did I place a key or something.

This started since Firefox 153.0 (Debian package).

When I open Firefox for the first time after a reboot, it opens my latest tab but all the other tabs on that window are lost, and they show as "ghost tabs" as seen in attached image.

No other issue, other windows are preserved properly when I Ctrl + Shift + N

i am currently using firefox 153.0. can i restore firefox windows- and tab-structure as in sessionstore.jsonlz4 from a previous.jsonlz4 originating from a previous firefox version?

My old laptop died, stranding my Firefox profile (including bookmarks and Login credentials for many sites). I am able to connect the old laptop's HDD via USB to port the old profile data to the new laptop, but I am afraid that copying the older files to the new profile will overwrite the newer profile data. I would like to create a second profile, in which to store the old data, in the newer laptop's instantiation of Firefox, but I don't see any information online about doing this. Is it possible to create multiple profiles in Firefox for this purpose? Thank you

Firefox updated and all of my tabs I had open are gone. I used those for organizing and remembering things. There's no option to open recently closed windows. No history of the tabs as a group. What do I do?

Firefox updated its version on my iMac desktop two days ago and all my bookmarks are gone. There's a message at the top that says: "For quick access, place your bookmarks here on the bookmarks toolbar. Manage bookmarks..."

All my bookmarks are gone as if they were never there. I have a My Passport Backup hard-drive but I don't know where I can find them and restore them.

it looks like mozillo ambushed me, did away with all of my setting I spent years getting where I wanted them and left a folder called Old firefox data on my desk top. how do I make it look and act like the old firefox? I do not want the side bar I want the icons on the same line as the search bar. I want firefox to be my default everything like it was. I hate edge but it seams the only way i could get rid of it was to uninsal firefox and reintal this new pink firefox home page. I want my home page to be foxnews. how do I restore everything from teh old data filke to this confusing new page?
