Firefox Support Forum

When I clicked troubleshooting mode FF unexpectedly closed my Private browsing session and all the tabs. How do I reopen them?

I did not expect FF to close on me like that. I thought that as I was in a private browsing session FF would have warned me that it was about to close had it been necessary.

I'm guessing that my open tabs have been lost permanently because you didn't warn me and that all that time I spent is now wasted.

Life is really simple except that other people make it problematic.

I use Mozilla as my browser on Windows 7. When I click on Mozilla I get an Error page which reads, " Server Error in "/" Application. Runtime Error. Not sure how to fix this. Can you help. Thank-you

I just got a new computer, and I'm trying to copy-and-paste a profile over from the old computer to the new one, but this doesn't seem to be working. Firstly, when I click on the Firefox icon on my new computer (Windows 11), the profile manager doesn't start up, so I can't choose the old profile. I've tried copying over all of the old files into the new profile folder, and that didn't work, either. What's going on?

Hi, I installed the new update yesterday. This morning, I cannot access anything through my usual Firefox browser. I'm making this report from Google - which is working fine on the same computer. When I try to access any websites, the usual tab opens with a greyed-out "X" (or hourglass?) on the left of the tab - then nothing happens. I've tried restarting - no luck. I suspect yesterday's update was flawed/had a glitch. Please help.

When a new bookmark is created it goes to the end of the bookmark listing in the left panel. How can I force Firefox to automatically put each newly created bookmark in the correct alphabetic position in the left panel Bookmarks panel? I DO NOT want to alphabetize the entire panel, I just want each newly created bookmark to go where is alphabetically belongs. I do not use folders so have one long list for bookmarks menu. thank Bob

Firefox detected a potential security threat and did not continue to noodlemagazine.com because this website requires a secure connection

I have a PC with Windows 7 64b that I have updated after having synchronized with two laptops and one Android. After that Firefox works on all the units except the PC. On that I can see all Firefox shortcuts and Firefox account. But when I try to connect to a web place the screen is blank. I have also tried to sut down the computer and start again. No change. RAM memory is okay, storage on unit C: is a bit small and the CPU is Intel Core i5 3470@ 3,2GH instead of Pentium 4 and 4GH. Should I go back to an older version of Firefox that is not som demanding or is there someting else I can fix?

Do you have my e-mail address? bernt@bernt-lindberg.se

On homesnap web site I get a pop-up window for homes.com. I can't get back to homesnap & I can't get rid of the window to redirect to homes.com. What can I do? Thanks

I've used Firefox for years and I like it!! I'm just wondering if there is anything Mozilla can do to counter the apparent collusion between YT and MS to coerce people into using Chrome, by means of YT degrading their videos when playing on Firefox?!

I am using Windows 7 and Firefox 115.5. When I close Firefox, it stalls and after a minute I get an error message saying Windows Explorer is hung up. Then if I can get an option to close the program. I have tried many ways to exit Firefox but nothing helps this. Thanks.

To log into my mortgage lender's site I have to enter my email address. Beside this field is the Facebook container symbol; mousing over it warns me that if I enter my email here, Facebook can track me. Mortgage Lender used to allow me to log in with a user name, but now requires my email address, which apparently gives Facebook access to track me. Tried speaking to the lender about this, but they simply assert there are no Facebook trackers on their site. So, any workaround for this besides just doing all my business with them by phone from now on?

At some point in the winter of '21 I created a folder of bookmarks that was saved in the 'bookmarks menu'. At a later date, hard to say when but probably '22 or early '23 I deleted these bookmarks. I now desperately need to recover them.

The oldest auto-backup from 'Manage Bookmarks' -> 'Import and Backup' -> Restore is dated mid '23 and does not contain the deleted bookmarks.

Is there any hope of recovering them? For example via the Recycle Bin or by using a data recovery tool? Or will they have been overwritten?

I closed all my tabs and reopened the browser bc I was getting lag on sites like X.com when typing my messages. Immediately after opening Firefox again, my homepage, MSN.com was loaded. I tried to click on the arrow to scroll through the different headline stories and nothing happened. I used Chrome & Opera to load the same page and they work fine. This seems like a Firefox thing. I have no extensions or permissions that deny me the right to click on anything. What is the problem?

I'm still using windows professional 7, it works for the most part. Unfortunately often the browser won't load or it will load and runs very slowly, then it shows a box saying close previous firefox. When it is running slowly I often have to hit the browser many times until the box shows up saying close previous firefox. Is this something to do with windows 7 or another completely different issue.
