The update Firefox 100.0.1 ( or 2 ) has a bug: Firefox doesn't "see" the Fritz!Powerline ( LAN over Powerline adaptors ) and thus I can't enter the Fritz!Box. Even typing the IP address of the Fritz!Box doesn't help, because there is "no connecting" beyond the PC. The hardware works, so I can send and receive emails, but I can't access the internet via the firfox browser. Stepping back to 99.0.1, I had to "create a new profile" and all my previous ( before the update to 100.0.1 ) settings were lost, all bookmarks vanished ... I am rather angry, you know? This mail I'm sending via my notebook, as I this connects via 100 Mbit Lan network from an other room and as I had to "register" just to be able to complain ...

Can’t find how to sign into uBlock because I keep getting request to download Firefox even though I have used Firefox for years. I can’t find a button to push to complete the sign into uBlock extension

My Firefox is v102, 64-bit, on W10 Enterprise. ESR channel. It keeps telling me I need to update.

Under HELP, it fails to download whatever it is trying to update. Even though I got v102, I tried the online installer (mozilla.org/en-US/firefox/new). Thinking about it now, I did not try an offline installer.

I been searching online and tried this policies.json file (github.com/mozilla/policy-templates/blob/master/README.md#backgroundappupdate) with these entries:

{

 "policies": {
   "AppAutoUpdate": false
 }

} {

 "policies": {
   "BackgroundAppUpdate": false
 }

}

But still not help.

Is there anything else I can try? There seems to be no simple option to click to not check for updates temporarily.

Thank you.

Hi, I use firefox for quite a long time, and in the last 10 months I have been having a very peculiar issue. I am unable to enter mozzila website on my computer using Firefox browser, nor any other browser. Because of it, I am unable to download update or contact support. To fix the problem, I had to download the Installer at work and save it to a flash USB, then install a newer version on my computer. I am currently contacting your from work. Please help me understand where the source of the problem is coming from and how to fix this block. Best regards, Tim.

Last year someone asked about 2 Firefox for Android applications; I just had two different copies of Firefox installed on my Win 10 laptop (one in an attempt by Microsoft to upgrade to Win 11) where all my data was in the old app named 'Mozilla Firefox') while the newly installed app was just 'Firefox' and had none of my data. I did not attempt that new install, it seems Microsoft did ?? They also mentioned wanting to redirect the new Firefox to specific Domain Name Service servers, rather than the traditional server addresses provided by the local network. Anyone know what's going on?

Look I have memory issues I already have to change my password & now I just got a recovery key as long as my arm. Do you people think any of us have such important stuff on our home, student computers we need the tools of a CFO or CEO of a major corp. REALLY I think it is time we realize 2/3 of the tools on a computer be it windows or moz:lla are superfluous. To make me have to remember that many numbers is torture or try to remember where I put the print out is mean. Is cruel and why? So our egos can feel filled with smoke? Anything more than 5 fonts is a waste. How much time do you think gets wasted while people "play" or fart around with all the empty tools on computers? The world wide web is a huge wall surrounding all the companies that take our money. You built it for them Then showed consumers shinny new toy we waste our money our time our lives and we will never be able to get into the wall you built to get back money we spent or time we wasted. A 15 number key, you think someone wants the answers to my midterm? If they need it Let them have it. You technological people, who build this trap, who blow smoke up where it tickles, should be ashamed.

I have a subscription to a business book summary service. Several of their downloads are sitting as "unknown time left" and won't download. The problem is, in order to stop this, apparently I have to lose all my downloads. They each have an X but it does nothing if I click it. How can I stop these downloads but not lose all that is in my downloads folder that I haven't saved or filed yet?

Hello, Last few days Firefox keeps automatically downloading strange files like mLZrOMIV.htm icFSREgF.htm

They are 0 bytes, empty when I open in notepad and if I right click in download section and select copy download link I just get about:blank

I checked PC for viruses using Eset Online tool and Windows defender. No problems.

Has anyone run into something like this?

Hello :) For some time now my firefox doesn't allow me to preview PDFs. If I open it, it gets downloaded at the same time which I don't need. I already tried the thing with renaming the handlers.json to handlersOLD.json but it didn't work :( does anyone know how to fix this?

I downloaded a Windows 10 update last night. It was Security Intelligence Update for Microsoft Defender Antivirus - KB2267202 (Version 1.361.793.0). Now, I cannot open Firefox. When I click on Firefox for around half a second I see an error box that says "Open Firefox in troubleshooting mode?" and nothing else, with no option to click yes, then the box closes. The same thing happens when I try to run firefox.exe -p to change profiles. I also cannot open Tor Browser, and I am wondering if there is a connection. I have tried uninstalling Firefox using the uninstall tool and reinstalling but I have the same issue. I uninstalled the windows update and opened Firefox. This time, it had the "Open Firefox in troubleshooting mode?" box but I could actually click on the yes option, and Firefox opened. However, when I clicked on the option to get a fresh install and remove the extensions, Firefox closed and I am back to the same place of it not being able to open again.
