Firefox Community Forum

I am unable to sign in due to Firefox reporting ISP FFL website security certificate being revoked. I do not remember my password to try another browser. Please help

I am using Windows 11. everything was fine Thursday the 12th but I did not use the computer at all on the 13th. Updates required a restart this morning. Now when I try to load Firefox and unlock Roboform I get an internal error message - unknown function call.

I read the existing articles and followed them, starting with "manage bookmarks". When I click on restore, there is a list of the last 15 backups by date. EVERY one of them results in an error message "unable to process the file".

Manually searching for bookmarks.html or json, results in nothing found

Please help

I open up firefox and the message appears - you must be signed into this network in order to access the internet. BUT i can use the internet. This is not a problem on a W10 machine which I also use.

Why is every company from Microsoft, Google and Firefox so obsessed with changing how I have my devices set up? I do not want all the extra feed as I open the browser. Every time the browser is opened there is so many more added shortcuts to my main screen. That is super annoying when I already had in place the shortcuts I wanted. I have gone through multiple times to dismiss the ones Firefox had added to the shortcuts. But new ones just keep popping up in the shortcuts. I have also blocked all the advertisements such as sports, fit health, politics and many more that is offered that I do NOT want. It crowds up space and is VERY distracting to my homework assignments. I just started using this browser because my college recommended that I install it to my laptop because Microsoft does not support 100% of their programming requirements. I wish the settings to find this would be easier and more available to the average Joe who is not familiar when changing browser settings. Plus it switch my mouse buttons. When I have always used the Left click on the mouse to select the word that needed to be modified auto correct spelling... now it is set for the Right click of the mouse. Why does every company feel the need to completely modify other peoples stuff? Same thing with my TV connected to the WI-FI. Ads are always popping up, modifying TV preferences, moving apps around on the main screen. Every time I power up it has a new screen. Its honestly disgusting. The world around us is always changing... can our personal home lives be left alone with our preferred preferences? With out major companies thinking "Heeyyy we can make that better!" without asking from the consumer! It would be nice to have the option when powered on asking "We have a new product, would you like to try it?" allow us to select yes or no! Or just fix the old stuff that had glitches... but nah we going to keep pushing forward and annoy everyone to fill our pockets! I am NOT pleased with the product that has been recommended to me.

It looks like my firefox profile got corrupted during a power outage is there a way to repair it or at the very least get back my opened tabs? I had lot of them and it will take a long time to find them all again...

The profile in the image i cannot open anymore:

The sound works for me on Opera (PC Win11), but not on Mozilla - I see it as a bug in the browser... even after clicking on the playback device in the bottom right corner in Mozilla, the sound doesn't start playing...

Why https://www.wunderground.com/dashboard/pws/IWOJEWDZ128 my weather station site for several months shows status offline and direct me at once to main site wunderground.com ? It is only on Firefox, Chrome, Android works normal and here it is online. Win 11, Avast Free, blockers (active adblock, ublock, ect.) In past several years was all ok I did change nothing with settings, blocker were in past also. What and where to look for?

Firefox is causing my wifi adapter to shut down

Running firefox for any length of time will shut down my wifi adapter at a random moment. The only solution is reboot

Using opera, the problem does not occur, I can run opera continuously without problem. Running firefox at anytime will cause the fail at some point.

Im running windows 11 I have run firefox in safe mode Disabled all addons Set to “No Proxy” Disabled power saving on the adapter Replaced firefox with the ESR version 140.8 , previous version was the latest I note that there are up to 11 firefox process instances in task manager (all cleared when firefox is shut down) Firefox is set to update automatically Several updates have occured during this problem Disabled hardware acceleration Cleared cache Latest wifi driver And a few more that I cant recollect at the moment

Running out of hair to pull out

Any idea’s?

For the last 2-3 day I have been experiencing a box that asks for my signature each time I go to a new website. I can't move the box. I can't screenshot it. Does anyone know how I can get rid of it?

After i installed firefox net jitter somehow appeared in my cs2. every time i play jitter is jumping randomly. Can yall somehow fix this i really enjoy using this browser but i just cant play with it running in the background((((

I had about 15 pinned tabs - unloaded - that I was saving for a research project. I shut my PC down and when powered up for the next session - all the pinned tabs were gone. I never thought to record the tabs via screen shot or something.

Is this normal - what are the limits of pinned tabs ? Do they expire in a day ? When the PC powers down ? When Firefox updates ?

Exactly what are the limits or boundaries for pinned tabs ?

I just accidentally deleted a day of history, now it has to relearn a bunch of stuff.

Please add support for undo, so that if you do it by accident, you can reverse it.

During the week of March 7-13, 2026, upgrade(s) caused the size of my bookmarks, fonts and tabs to shrink to barely readable (see attachment) in the Firefox browser window on my Windows 11 PC. I've tried every internet base advice article. How do I increase the size of them?
