Firefox Support Forum

I have been getting this error lately. Later I noticed it only seems to happend when Firefox is running. literly can't find anything online what so ever. So this is baffeling. I don't believe I have done anything to make it happen. I have had like 1,350 tabs before Firefox had an update (and it fked it up) so it might of been some update. Firefox hasn't been nearly that good sense. Im prob at 150-200 tabs right now and I have never seen this message. Also firefox LOVES ram. I have 16GB and over time it EATS it. like 12gb and when i hit 99% the computer slows down of course and I have to restart. All bc of firefox... see pic

' bold text' Good Evening,

 I had an update to install on my laptop for Windows 10 and now Firefox does not open. I have tried everything, uninstalling, reinstalling, standing on my head and nothing works. Can you please assist?

Thank you, Christine Gernant

When you open other web browser, it starts with the cursor on the search bar ready to type and search. I wanted to know how I could change it so Firefox does the same.

I'm not sure if this is a question or not. But when I had a friend log out of my account on my PC Firefox browser and sign in to hers, it merged her personal data to my local PC and then merged with my own account after I logged into mine. There's an option to delete it, but if you accidentally don't check it, it stays there. She tried logging in and logging out and checking the delete local files, but her information is still stored on my PC and account. Funnily enough, later that day, I logged into her PC and browser and it's the same thing there. We only realized this just now. Is there a way to fix this all at once?

It'd be much preferable if Firefox accounts were instanced by default, and all personal data is exclusively with that account. With options to merge or download information longer term.

Hi, because of a crypto scam (already 2 weeks ago) i am looking to recover my browser history? I need the information for the company which investigates my case.

I found some info online to recover, but it only worked a little, but not what i was looking for? 

I hope somebody can give some instructions , tricks to try to recover something.

greetings, Kyri.

Hello I installed Kaspersky in my PC but I no longer uninstalled I see anytime I open the browser Firefox likely a black screen covering the page but it vanishes as just as the browser full-opened, so what's this by God ? It is the first time I have seen Before I installed the Kaspersky antivirus it didn't appear. I thought it is a matter of protection But after uninstalling Kaspersky ( antivirus ) the black screen is still seen  ??

So, for some reason today, Firefox keeps minimizing whenever I click on it. I click on the Firefox logo in my doc, I see the browser for a second, then POOF a second later it minimizes. It's odd because the app seems to be working fine. In the split second that the browser was on my screen, I'm able to type a single letter, and all button functionality works. I even got it to go into safe mode, but the problem still persisted.

This is only Firefox-specific. Not having problems with Chrome or Safari, but Firefox is my browser of choice, so it's kind of annoying.

But for more details and troubleshooting,

- I'm running on a 13inch Macbook x86 on BigSur, so not the newer M1 Mac. - I've turned off and restarted my Mac Book. - I've uninstalled and reinstalled Firefox - I've used AppCleaner to get rid of all leftover files and then reinstalled - I've forced quit the app many times - I've tried the private browser and still nothing - My Mac is up to date and charged - I've run Malwarebytes to look for viruses - Firefox works on my IPad, so it's not an account issue

None of these attempted solutions worked.

Also, I can't reset Firefox or provide any troubleshooting information because the browser closes too fast before I can do anything.

Here's a video showing the problem: https://youtu.be/y3k-Q-eRyE4

I downloaded Myki Password Extension. I have the program installed on my computer, but I can't figure out how to get the extension 1) To the main toolbar, and 2) to record my usernames and passwords and 3) Autofill as a result.

I am getting these errors in the browser console. I am using Firefox Developer 87.0b6 I have disabled all telemetry options except for telemetry enables, because that is locked, but I am STILL getting pin errors. https://support.mozilla.org/en-US/questions/1197144 See my about:config settings below. How do I stop this? The errors are particularly annoying because they don't clear when refreshing a page like other errors. Debugging is extremely painful.

After last update, Version 86.0, when trying to watch an event on ESPN, I get "n.accessEnabler is null" and the event will not play. This was not a problem until the last update

I did not know until now that the Firefox Notes service was being discontinued. Now, the app disappeared from my phone and there is no option to get the synced notes as the Firefox Notes status article mentions. I have some important information on there. Is there a way to recover it?

The great thing about DNS over HTTPS is that it's done at Application Layer. However, Firefox doesn't leverage this - producing a boilerplate response when DNS response failed.

I'm using NextDNS with P O R N category blocked, with https://dns.nextdns.io/XXXX as my TRR (and network.trr.mode is "3")

When NextDNS does its job and responds with Server failed, Firefox should be able to produce an informative response to the user, rather than "Firefox can’t establish a connection to the server at P O R N .com." which is more about connectivity than DNS failure.

Feature Request: Firefox be more informative DoH DNS failures?

Stretch Feature Request: if network.trr.mode is "2", Firefox passively notifies user that preferred method failed.
