Firefox 社群討論區

I've been a loyal Firefox user since version 2.0. but to this day you guys have not made it easier for users to restore Firefox profiles. We in 2026 should be able to do the following directly from the user interface of Firefox. honestly its really taken me a long time to voice this opinion but it makes the app a tad less user friendly. i mean its easier to import from another browser but you have to pull out and search all sorts of folders to import from an old Firefox installation or a windows refresh (windows.old). Please, please implement this ASAP. we users have waited too long.

1. display a list of profiles (even from windows.old after a windows refresh) 2. automatically import that information 3. append existing bookmarks from the bookmarks backup if i choose to. 4. be able to browse the bookmarks and show the most recently used ones 5. be able to even reinstall the existing plugins (this one is minor)

the image attached is exactly showing what happens after a windows refresh. this feature is also great for administrators.

My mac froze, force quit did not work, unplugged it, turned it back on, all bookmarks were gone and not able to add new ones. Would like to restore old bookmarks and add new ones.

Hi,

i can see all my previous tabs in history but can't reopen window?

I didn't close those tabs, one time i opened mozilla and they were all closed.

Help me, thank you

""What happened:"" Yesterday I updated Firefox to 151 and noticed a "Profile" feature for the first time. I created a new profile, then saw a small icon with the Firefox icon that bothered me and realized it belonged to the new profile. I thought that the newly created profile is safe to delete and has to data within, so I deleted it. After that, Firefox deleted all old data and created another new profile and I lost old bookmarks, passwords, and browsing history.

Note: no warning was showed before deleting the profile.

What I tried: 1. Checked about:profiles profiles: no old data. 2. Opened the profiles folder in C:\Users\[my account]\AppData\Roaming\Mozilla\Firefox\Profiles: no old data found. I noticed one of the default profiles contains a places.sqlite file that’s about 2 years old: no old data, only default bookmarks are there. 3. Used Recuva to try to recover files — I recovered key4.db, login.db, and places.sqlite-shm but nothing useful so far. Environment/details: • Firefox version: 151 • OS: Windows 11 • No Firefox account Questions: • Is there any way to restore the old profile data from the files I recovered (key4.db, logins.json/login.db, places.sqlite-shm)? • Any other recovery steps I should try? • how to prevent the same thing in the future? Thanks

All but 2 of my previous saved windows have been lost. They are not recoverable or present when trying to use "Recently closed windows." How could this happen? More importantly, how can I recover them? They contain numerous tabs that will be impossible to recreate from memory.

Dear Mozilla // Firefox persons - you really know how to shoot yourself in the foot.... I am fed up having lost all bookmarks and not able to initiate anew despite intolerable checks for updates, restarts & reinstalls. Really pissed me off. Your "help" pages are grossly overpopulated with waffle and dead end links.

I got logged out of my Firefox account and upon logging in a bunch of dummy "sync" data replaced all of my bookmarks, settings, ect. Is there any way to undo this?

Hello,

I hope you're doing well. Unfortunately, my Firefox account was still signed in on my old mobile phone, which is now being used by my father. He accidentally deleted all of my bookmarks, and I have completely lost access to them. To make matters worse, I do not have any offline backup of my bookmarks.

I was wondering if there is any way for your team to restore the bookmarks associated with my account to a state from before December 31.

Thank you very much for your time and assistance.
