Diễn đàn hỗ trợ Firefox

Hello,

I just moved from Windows 10 to Linux Fedora Workstation and I used the "Back up and restore" option in the Sync Tab available in Firefox on Windows 10 to save my data in the form of a unique html file. (https://support.mozilla.org/en-US/kb/firefox-backup)

But now that I'm in Firefox on Fedora, this option does not seem to be available (in the Sync tab in Settings). Is there any way I could at least recover my bookmarks ?

I'm using Firefox 147.0.1 from the official Federa repo.

Thank you for your help.

I had a ton of saved tabs and groupings of tabs. I closed what I thought was my only open Firefox window then downloaded and installed the most recent Windows update. When I rebooted, I did not realize I had left a Firefox window open with a single tab. That Firefox became my default and I lost all the tabs I had. Is there any way to get those tabs back? The tabs I had yesterday, 1/22/2026 are the ones I need.

My Bookmarks and History are completely gone. I tried the recommended procedure to restore them from a back-up, but the supposedly automatic back-up files are completely empty. I have no idea how this might have happened. I have tried disabling some of my anti-virus apps to no avail. The only thing I can think of is that I may inadvertantly erased them when I ran a CCleaner scan. I could really use some help here!

I had bookmarks and backgrounds and everything saved on my browser. My mac book died and now when i open it everything reset. I didn't have any profiles or sync on but why did everything reset. And am i able to get what I had back.

lost all bookmarks and can not add them back. tried the restarting, importing from Google, etc. Sadly I am off of Firefox after more than 20 years using it. Fortunately Google works fine for me, but I miss Firfox.

After running cc cleaner and even that i de select the book mark and side setting the Firefox Bookmars and history is non functional . i did create a new profile yesterday biut today i have the same Issue. I uninstalled CC CLeaner but i want to restore my Bookmarks system i need help with that. the explanation here are not really helpful

I started my computer bookmarks and password were gone. I can't find them in profiles or I don't know where to find them in profiles. I need this stuff obviously. It takes me forever to reset everything. What if anything can I do?

I had around 3000 tabs open I closed the browser completely today. Normally when I reopen firefox all those tabs were appearing still. This time none of the tabs restored I can see tabs in history part namede 19.01.2026 although not all my tabs are there. When ever I try to reload them from the restore history part; firefox doesnt reply and doesnt take the command.

I am on MacBook Pro Venture 13.4.1, firefox 147.0.1. How do I restore old windows with their tabs? I tried to have only one of my 5 windows (with tabs) opening every time I opened firefox. Always two opened, the second one was always the same and not one I had most recently used. Couldn't find an answer, so I went to settings and turned off "Open previous windows and tabs" and turned off firefox and back on again. Then all my windows were gone! How do I get those 5 windows back?
