Firefox 社群討論區

I had a power outage occur recently and when i booted my computer again I found that somehow my Firefox account was disconnected. All of my bookmarks and history gone, but things like accounts and site preferences were kept. The problem is that firefox is not saving my history and bookmarks cannot be made. I have checked common causes for this problems, like not activating sync and turning off "remember history", settings which were set up correctly.

i had two different firefox browsers yesterday. I deleted one but all my passwords are gone from the other browser. When the firefox browser got uninstalled it created a backup on my desktop called bookmarksback up. how can i move that file into this new firefox and how can I retrieve those passwords?

nach dem start von firefox erscheint ein völlig neues profil - alle vorher gespreicherten tabs sind verschwunden. gibt es eine erklärung oder hilfe, um die vorherige ansicht wieder herzustellen?

you have removed ALL my bookmarks every time I reboot Firefox. This is intolerable!!!!!!! You have cost me 24 hours of insufferable time trying to reinstall my hundreds of bookmarks.

So before few days firefox decided to automaticly update. after thet no pasword was saved in system. undery system data 2 files: logins.json-1.corrupt/json-2.corrupt without any data in files (but size is 130KB). i need these logins ASAP.

Logged on to find this message. Followed "Fix" set as best I could (I am puter dumb) with no joy. "Manage Bookmarks" is completely blank. All wits end, Please HELP!

My Firefox crashed and one of my windows with a bunch of tabs was lost. I have a bunch of windows open for dedicated sorting of tabs (one for socials, one for videos, etc). Earlier, my Firefox crashed and it attempted to restore my session but did not restore one specific window I had. I looked in the "History > Recently Closed Windows" and it was not there either. This specific window had a bunch of work related things on it and while I can sift through my history and re-open each tab individually and rebuild it that way, that's really frustrating and time consuming. Is my window just lost now?

Running v150.0.3 on a Windows 10 PC. I have (HAD) 5 windows open with about a dozen tabs in each one. Just realized that one of the windows is gone! Every time I startup Firefox, I always allow it to automatically update the version. I have a bad feeling this missing window issue happened during the most recent update (last week?).

Has anyone ever experienced this issue or have any ideas how this could have happened? Any chance of recovering that window? I have weekly backups of the SSD containing all my Mozilla files & folders (Firefox and Thunderbird).

Thanks

the last update of firefox wiped out my amazon account on my pc. It completely cleared my calendar. Messed with my passwords on some of my accounts. Can someone tell me how to get these things back. I am not a computer wiz.

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

My old laptop is broken; I can no longer access the hard drive. Is there any way I can reorganize my old bookmarks from before a specific date, i.e., December 15, 2025, in Firefox?

Firefox has complained for sometime that my profile was created with a newer version than what I was using. I'd click OK, and go about my day. After about a month, I decided to upgrade so it would stop bugging me. When I did, my old profile did not merge, but was deleted, and now I have lost all of my passwords and bookmarks. How can I restore them when the profile is empty?

Is there any way I can retrieve my bookmarks from old installation of Firefox? I lost my bookmarks due to fault on my PC. I have a new drive and have reinstalled Firefox on this one. Any advice greatly appreciated. Thanks

I had my computer fixed due to a virus and now I can't get my old firefox with all my saved passwords back. How can I get it back. I'm using my same email address.

My bookmarks have disappeared. I have followed the steps to restore them under the FAQ, but at Step 2 ("In the Library window, click the import-export-arrows button and then select Restore"), when I click Restore, no list of backups appears from which to select the one I want to restore. I have been using Firefox for years and have loads of useful bookmarks. How can I get them back?

I used Firefox yesterday. My settings are to open Firefox with tabs restored - but all my tabs (as they were yesterday) are missing and when I go to history, the option to restore a recent window is greyed out. The option to restore a previous session doesn't even seem to be there.

I notice in task manager I have 15 firefox tasks. Could my window from yesterday have opened somehow in the background, but not be visible to me anywhere?
