On Windows 10 with 64-bit Firefox, after updating from version 144 to 145, some local HTTP-only servers stopped working and became inaccessible. When I enter http://<local server name>, after a few seconds it automatically changes to https://<local server name>, and since no HTTPS service is running, it ends with a “Server not found” page. It seems to be related to DNS — accessing http://<IP address> works fine.

I tried a clean installation with a new user profile, but it didn’t help. Downgrading to version 144 fixes the problem, but at the cost of losing the user profile (which is a disaster). I also tried to check the HTTP-only settings (which I’ve never modified), but that didn’t help either.

Is anyone else experiencing the same issue?

My account has my primary email and it used to have my secondary email connected as well. I now want to create a new account with the secondary email so I can have another profile, so I deleted my secondary email from the manage accounts on my primary email. I ensured that this says it is removed on all devices and it is. But when I try to create a new account with that secondary email, I keep getting the error that I need to sign in my primary email and I am taken back to my profile with my primary email.

How can I fully detach my secondary email so that I can make a new account with it?

Firefox detected a potential security threat and did not continue to myccp.ccp.edu. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

For years I have clicked on the clear history, clear data and manage data on the settings page in privacy and security--directly after leaving every website, just to be sure...now nothing is happening when I click on them. FF is up to date and nothing is different (that I know of).

Please help. Thank you.

hallo, I use "Qwart" Browser as Internetbrowser in Firefox extension. But I can't see an Qwart-icon on menue-strip. I receive a message "Quart-Search engine can't read and change data from this Webside" Extention best regards klosterberger

Unsure if it really matter, for now, but my firefox account, when I go to edit bits and pieces, it gets my Firefox version correct, but gets my MacOs version wrong. I'm on 12.76 (Monterey), but Firefox is showing me as 10. Is this normal or anything that might matter?

And a screenshot below just for those, like me who, prefer a book for it's pictures

I'm trying to stop Firefox from restoring tabs after I restart my OS. So far, I've done the following:

• Disabled `Startup > Open Previous Windows and Tabs`
• Disabled all extensions
• Confirmed I do not have a `user.js` file
• Set `browser.sessionstore.resume_from_crash` to `false`
• Set `browser.sessionstore.restore_on_demand` to `false`
• Set `browser.sessionstore.resuming_after_os_restart` to `false` (It was already set this way.)
• Set `browser.sessionstore.max_resumed_crashes` to `0`
• Set `privacy.clearOnShutdown.openWindows` to `true`
• Set `browser.sessionstore.max_tabs_undo` to `0`
• Set `browser.sessionstore.max_windows_undo` to `0`

(I've since reverted the last two and the extension changes after they didn't work.)

So far, Firefox will not restore tabs on application restart (manually closing and relaunching) or on crashing (after sending SIGTERM/SIGKILL), but it still restores tabs after restarting the OS (if I allow the OS to kill it during shutdown). I've seen a couple suggestions to disable history completely, but I do occasionally refer to my browsing history, so I'd prefer a less-drastic approach. Ideally, I just want Firefox to treat the first launch after a shutdown as a normal launch and not apply any special behavior. Any help would be much appreciated!

Hello, I am facing an issue while playing YouTube videos in Firefox. The videos are lagging and not playing smoothly, even though my internet connection is fine. Please help me fix this problem.

Just built a new PC and using Win11. I like to have a pinned tab in Firefox playing some kind of media to have background noise. Since new build, whenever I am not 'focused' on that tab and doing other tasks, audio from that tab will cut/fade in and out.

I've been working on this for 16 hours. I've googled, binged, even yahooed. No answers. Checked and rechecked all settings, both system and browser. Uninstalled/Reinstalled *many* applications, including Firefox. My OCD won't let me rest till I have this solved.

Thanks for the help.

Each time I open Firefox a black symbol appears in the upper right of the Firefox Icon. This began several days ago. What does the symbol mean? See attached image. Is there a way that I can remove this?

I have received 3 system alerts, all from Mozilla Firefox (I use Firefox as my default browser). 1) System is infected!---click on d45n9f8ko90s738b610.gsx-protect.co.in 2) ZEUS.2020 Trojan detected--with same directed site 3) System Alert!---with same directed site.

I use McAfee as my security system. They recommend going to Firefox settings and disallowing random site connections. How do I get my system running again.

Latest McAfee scan shows 45 entries deleted and 2 browsers reset

Firefox updated to the latest version and it lost everything. All my saved passwords are gone, all my bookmarks, data, etc. It said I could sign in with my account and it would sync them and bring them all over, it didn't. I can't use the original profile because it says it's outdated, I don't even know if it's the correct profile anyway. What am I supposed to do?
