Firefox 技術支援討論區

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!

i had some problems with windows services and firewall and network. i installed the tool from tweaking.com( i don't know if it is legit or scam or virus or anything. would appreciate clarification.) after i repaired windows with it some of my apps including firefox did not start and were corrupted. after that i wanted to reinstall firefox and used the helper.exe from the uninstall folder in mozilla firefox folder in drive C. it restarted firefox and all my tabs were gone. i accessed the jason files (recovery,restore,...) and none of them had my tabs. i signed in to my account and all my history and bookmarks are still here but about 100 tabs were lost. i really need those tabs and i am in desperate need for help. thanks ( in no parts of system repair or other actions i have not created a back up and do not have that back up or system restore files)

No sure if this is the right topic. When I search something and go to the tab section, all the news sources are redirected from MSN. I don't want to see MSN holding the article from a legit news source, I want to click the news article it comes from. I hate MSN, I just want to access the news from the original sources. (example MSN

How do I fix it so I get news sources that originally hold the articles?

This is such an irritation I will be forced to find a new search engine if this is not fixable.

Any help would be appreciated-- especially if you are able to walk me through the steps or provide me a link to a specific source as I don't know much about settings etc.

Thank you so much for taking the time to read and (hopefully!) help.
