Firefox Support Forum

I am accessing my ISP to download the security software. I need to be able to select the Operating System. When I click on the drop down box I am prompted for the OS, but when I select it the drop down box does not populate. I then get a message to select the OS. This works with Microsoft Edge.

I have BitDefender and I keep getting the following notification: BitDefender blocking connection to gitcdn.xyz due to unmatching security certificate by firefox.exe. Can you please correct this?

Thank you

Hi,

After restarting my MacBook today, it seems like Firefox has been updated. When I signed in to my account, all of my passwords as well as my search history and personal customization have been deleted.

This is a very unfortunate situation. Please advise on how this can be restored.

Kind regards, Oskar

Hi!

I'm having an issue where everything on the browser flickers whenever i'm scrolling.., i've tried to search for some help on the issue but im stuck.., can someone please help with this.

This problem occurs on My wife's and my machines. My wife has a printer. I do not. When we try to print the preview shows only a few lines or at best a half page. Even if we want to print multiple pages that's all that shows up. We have "print all" as the default setting. The problem started about a month ago. I think it has something to do with the newer versions of Firefox.

My account names to all of my email masks have disappeared. Why did this happen? How do i get them back? Now I have not idea which email masks are for which accounts.

i had to reset my laptop due to certain reasons ..but i didnt back up things .as i re-downloaded firefox and logged in with my old account ..i didn't get me logg-in passwords for various sites back

a few days ago, i encountered this weird symbol on my toolbar (check image). it basically looked like a blue keyhole, and this was the first time i encountered something like it, so i ran a gamut of virus scans from many different tools to see if it was a PUP virus or whatever, but nothing came up as a hit. I was puzzled on WHAT it was, but after i shut my browser down and rebooted it, the blue keyhole symbol vanished

so.....wat was dat?

I keep being told on certain websites to turn off my ad blocker. I don't have one. I don't even have one in the Extensions that's disabled. I have no idea how to get past this. What's turned on that I don't know about?

I play diggy's adventure when I select full screen the game stays the same size but at the top of the screen the bottom half is black, I tried on a different browser and it works ok.

I make frequent use of the Windows system-level keyboard shortcut Windows Logo button + M to go directly to the Windows desktop. Firefox does not respond to this keyboard shortcut by minimizing. How can I fix this? I already tried refreshing Firefox. This is a big enough issue to get me to abandon the browser, since I depend on keyboard shortcuts.

Windows 10 64bit pc. After factory reset and reinstall of Firefox, 2 extensions are enabled but the menu bar won't allow them. These worked OK before the reset.

Troubleshooting within Firefox won't work because it disables the extensions.

The messages from Extensions say "Can't read and change data on this site" The extensions are enabled (turned on).

The 2 extensions are Malwarebytes Browser Guard and Video DownloadHelper I am using DuckDuckGo as my browser. I tried switching to Google, but same problem.

Ccleaner gives message of "Firefox needs to be closed. i though it was Ccleaner that was the problem. it's not Ccleaner's problem... I get the same message when I run advanced system care... when I click 'close for me' it just skips it over and over. i then run it after starting PC and it still tells me FF is running. the 1st time it lasted for weeks(summer-ish of 2023) and seemed to fix itself. and it also wasn't fixed with 1 or 2 FF updates because i was waiting to see after updates that it would be fixed but wasn't. And I can't find Firefox running in Windows or advanced system care task manager. which means i cant close it manually. so I'm pretty sure it's a Firefox system problem... somehow FF is still running hidden in the background. i run malware fighter and anti virus to see if something is using it but comes up empty.
