Firefox 技術支援討論區

It seems firefox has changed the behavior of tabs. When I go to open a closed tab, I see a list of all the tabs that have been closed from every window. I want to restore the previous behavior where "recently closed tabs" only shows the tabs that were closed in the current window. I saw some about:config settings, but I'm not sure what they do and I don't want to end up losing the tab history all together.

Thanks

The plus sign in the tab bar has always been on the far right side. I reloaded Firefox yesterday and now the plus sign is directly after the tab. How do I get the plus sign back to where I like it?

I was having issues with my laptop so I decided to do a System Restore to a previous date. Once completed, I opened Firefox and tried to restore previous sessions, but none were found. I also noticed that the shortcuts were blank, possibly uninstalled. I clicked on shortcuts and nothing opened. I downloaded Firefox again and reinstalled, but now I cannot restore my previous sessions. I tried to restore going to History>Manage History>Import and Backup>Restore>Choose File and selecting previous.jsonlz4 and recovery.jsonlz4 file with a date from last month, but again nothing happens. I searched around for answers, but only came across instructions to compress jsonlz4 file and decompress using mozlz4 without any instructions on how to use it.

What else can I do?

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!
