Firefox Support Forum

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)

I have been getting a message that says firefox has something running and cannot shut down. I went into task manager and 'shut down' firefox, but the message keeps on coming. I then thought that I would uninstall it and then reinstall, but it tells me that it cannot uninstall because it is running, -"Firefox is already running but is not responding. The old Firefox process must be closed to open a new window." When I click on ' Close Firefox' nothing happens. when I click on 'Cancel' the message disappears, but will reappear. Then in desperation, I went into program files and deleted the Fifefox folders but it wouldn't reinstall. There is obviously somewhere a file/file which is screwing me up, does anyone know what this it?

Hello, Mozilla Community I'm contacting you to ask for help with a Mozilla Firefox problem I'm having with trying to visit the following website: The website https://strandsarchivenyt.com/ It won't load, and I'm not sure if that's because of a bug in the website, a browser issue, or something else entirely.

Does anyone else have knowledge of this problem or recommendations for a fix? I've attempted removing addons and cleaning the cache in my browser, but the issue still exists.

I would be grateful for any advice or ideas on improving the usability of the website. Thank you in advance for your assistance.

I had issue with notifications (showed up but when i click on them they didnt were redirecting to original tweet) so i cleaned cookies after cleaning cookies i doesnt have option to turn on push notifications.

Hi, I am having in issue with YOUTUBE AND google services and it pissing me off, when I ever open a tap in youtube and load very slow! even when I open a video with out open it in new tap, I have tried to delete the browser and download it again it didn't work I even bought Yt premium and turned off AD block still the problem didn't go away, also how search bar on the top of the page isn't working, when I use it and search it gives me an error, Error code: SSL_ERROR_BAD_CERT_DOMAIN I am considering to change the browser it's so annoying to use in this way.

If I have a chat open or the video has a chat replay instead of showing the chat it pops up a mini browser instead. It constantly duplicates itself too, causing the video to be unwatchable with the sound constantly repeating. I've seen a couple other people with this issue but have been unable to find a solution.

Hello,

FIrefox is not loading new pages from the home page- it will load history I've saved or previous tabs, but opening a new tab and searching or typing in a website won't connect. Uninstalling and reinstalling briefly fixes the issue but as soon as my computer enters sleep mode the same thing happens. IS there a way to fix this? It's been happening for about a week now.

When photos, videos, or websites are linked on a FB comment, it used to display a thumbnail preview below the comment. Now it just shows the link. On mobile, the preview appears. So I'm thinking a setting got changed on the desktop version.

Does anyone know what the issue is and how to correct?

Outgoing emails are blocked. This pop up shows. Receiver can send emails in.

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Connection refused - OB119. 206.83.122.10 is blacklisted in Abusix Mail Intelligence. See https://lookup.abusix.com/search?q=206.83.122.10 e{d292e9f3-c0c7-4d3c-b9ee-2a1d5d37c016}.

For a few weeks now, FIrefox will not play DRM content video on this computer. I have tried all the suggested solutions and none have worked. Also, I uninstalled and reinstalled Firefox, but the problem remains. I am very frustrated with this problem and am ready to get rid of Firefox permanently on ALL our computers unless this can be fixed.

Thank you in advance for your assistance.
