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)

When switching from one tab to another, streaming stops and video won't play in background. I've tried all the main fixes suggested I've found. Nothing worked. Please help! Will be using alternate browser until fixed as it's too unwieldy for me to use this way.

When opening a new website when a window is already opened I want Mozilla to add a tab and not create an entirely new window. How do I change this feature which presumably is in "settings".

New tab opens to blank page and not my home page, which is Google. I have been to setting and went to the drop down box for tab settings but it only gives me an option to make firefox my home page or a blank page. I want Google to be what appears in my new tab when I click on the little + isgn.

Where are all the tabs for the research I was working on? I stepped out of my office for a few minutes and returned to a very proud message declaring that Firefox had auto updated and now better than ever. Only all my tabs are gone. Why does every other browser save and restore tabs when updating, but not Firefox??? Do I have to go back to Safari or Chrome? This cannot happen!!!

Whenever I select tab and then start typing in the page search box it automatically jumps to the URL/Address bar. This is not only annoying but it makes it difficult for me to see what I'm typing, and it often results in unwanted typing errors. I have yet to encounter a single longtime Firefox user who thinks this is a good idea, but I have met several who've decided to drop Firefox and start using Chrome just to be done with it. I've been using Firefox since early 2005 and I've mostly been happy with it but this is just to annoying to continue. I'm complaining because the feature exits, I'm complaining because there's no option to opt for those of us who find it annoying and will never become comfortable with it.

If there is a working fix that I've been unable to find, then please point me to where or what it is so that I can apply it.

I have many tabs open at the same time and I'm noticing tabs from Urban Dictionary in particular are automatically changing to suspicious sites, quite a few porn sites in fact.

Is this something Urban Dictionary is doing to direct viewers to sponsors or is there a bug in my FF browser?

When searching with google it always opens a new Tab with some not working Address. Whether i just search or click on pictures or look at a picture more in detail it always opens this tab: Look at picture: At this point it is really annoying and in the settings of the browser i don't seem to find a solution. Please help.

Every time I open a new tab, another extra tab opens automatically with the following address: https://0.0.0.1/

showing this message: An error occurred during a connection to 0.0.0.1.

I already re-installed Firefox but this bug keems popping up.

BTW: I did not do a d*** thing. It just started yesterday and is extremely annoying!

I am afraid to update to Firefox 124 for fear of losing the existing order of 100s of open tabs if the default setting of ordering tabs by "Recently Opened" kicks in before I have a chance to change the setting to "Tab Order". Can anyone help me? I'd like to upgrade to 124 if I can do so safely!

I just migrated to iMac 2019 27" with Venture OS from imac with Yosamanite. Firefox looked weird with TINY tabs and search window, Too much space. I've tried updating and restarting Mac but no change. Same with themes. You can see the screen with open Firefox.

Hello Good People,

I installed Firefox a few days ago and it was looking good. I don't like that icon in the top-left hand so I right clicked it and removed it. All was good. However, today there is a blank black space in the corner as if the icon was back (but without an actual icon). It's only a small thing but it bugs me. I want the tabs to be shifted all the way over to the left like they have been up to today. It's triggering my OCD. Anyway, any advice appreciated.

Best Wishes

I am on a brand-new machine and having trouble setting up the Firefox browser.

When I click on a link it opens in a new window with all the tabs ready opened.

How do I open a tab without opening a new window?

Also, how do I set Yahoo.com as my default search engine?

Thank you for sharing your wisdom

I received a scam Apple (security) popup (on which I never clicked) and from that point on, some 30+ obsolete tabs congregate across the top Firefox browser window. How do i lose all these unwanted tabs?

I am watching a Twitch video on Firefox. When I open a new Firefox tab and drag it to another monitor, the Twitch video skips forwards about a minute.

I also occasionally notice skips or pauses when I switch from one tab in the same window back to the Twitch playing tab.

Is there any way I could fix these problems?

The pinned shortcuts on my newtab page have all disappeared once again. I've gone to about:config > browser.newtabpage.pinned and my shortcuts are all listed. But only blank boxes show up on the page. It will not accept a new entry when I try to enter one. It goes back to the blank white box. Why does this keep happening? Can anyone give me a Firefox for Dummies way to fix this?? Thanks!
