Firefox 社群討論區

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

Yesterday I got a prompt saying there was an update available for download. Today when restarting my laptop and opening Firefox ALL of my bookmarks are missing!!! My bookmark toolbar is also empty. Where did all of this important stuff go? Please help me restore this my information asap. I am freaking out!

I just updated to the latest Firefox. All my history, bookmarks, extensions are now gone. I do not seem to be able to get them back. My old version of Firefox is not available. When I ask to update from a prior browser, the drop down selection does not give me my prior version of Firefox. Help!

items dragged to overflow menu pop back out, will not stay there - dunno how to fix this.

Hate the "puzzle piece." Involuntarily upgraded to 115.25.0esr and it lost all my bookmarks, addons, history. How do I know which profile was the most recent, before the update added a new profile? How do I find my addons from the previous version? history?

Where are my bookmarks? Everything is gone with the update, and you didn't warn this could happen. Is there a way to recover the bookmark file? Profiles does not help for there is no new profile there. I NEED THE BOOKMARKS FOR WORK!!!

My bookmarks have all disappeared, and while I have tried to follow the instructions on the help page to restore them, nothing is working as it has been indicated that it should in the help instructions. I do still have my Bookmarks tab on my tool bar. When I click on it I get a pull down menu, which does have a Manage BookMarks bar. However it is not at the bottom of my pull down menu, but at the top. When I click on the Manage BookMarks bar, instead of getting an Import and Backup Button, my pull down menu disappears, so I can not select Restore to use to get dated backups.

In the same way, I can not create new Bookmarks. When I click on Bookmark Current Tab, instead of getting the white box to enter instructions, the pull down menu disappears, just as it does when I click on Manage Bookmarks. I have never had this problem with Firefox before in all the years I have used it. I have no idea what has happened.

my desktop has changed i used to have buttons to access frequently used sites appear when i open firefox and now i don't, what happened and how do i get that back, in addition all my booklmarks have disapeared how can i get it back

Dear Mozilla Support,

My name is Sizhe Xiong. Today when I launched Firefox on my Windows computer, the browser suddenly required me to select or create a new profile before continuing. I had no option to skip this step, so I created a new one.

After that, Firefox asked me to log in or register a Mozilla account. I used the same Gmail address that I’ve always used for Firefox Sync, but it seems that a new account was automatically created, and all my previous data — including bookmarks, history, saved passwords, and extensions — disappeared.

When I checked my local Profiles folder under C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles, I found several new folders created around the same time, but none of them contain my old data (all places.sqlite files are around 5120 KB).

These bookmarks and passwords are very important to me. Could you please help check if it’s possible to recover my old Firefox data, or if my previous Sync data can still be linked to my Mozilla account (using the same Gmail address)?

Thank you very much for your help.

Best regards, Sizhe Xiong

Some of my shortcuts were missing on Firefox when I started my laptop this morning. I tried restarting my computer but that didn't help. I really don't know what topic fits best. I am not at all tech savvy when it come to computers.

so, update to 138.0.4 (64-bit) resulted in deletion of both my bookmark library AND all the backups? fantastic. over a decade of important bookmarks - gone. thanks guys, you're awesome.

For the second time, FF opened w/o restoring the previous session's tabs. The first time I was able to restore the tabs. This time I can't. And can't figure out how to fix it or why this is happening since I have the restore previous session box checked.
