Firefox Support Forum

When accessing my site (in attachment to avoid indexing), Firefox blocks with a "Possible security risk" interstitial. DoH requests to the configured https://dns.google/dns-query service work from an external application on the same machine as the browser, but about:networking#dnslookuptool reports the host being unknown.

OPEN PREVIOUS WINDOWS AND TABS is unchecked but upon startup firefox always tries to do this and I get an error message. Computer crashes, shutoffs, sleep mode and Firefox wants to go to my previous windows and tabs : I HAVE IT UNCHECKED FOR A REASON, I DON'T WANT TO GO TO PREVIOUS TABS.

I can add the short cuts I want but if I go someplace new Firefox will add it to my shortcuts without permission. This seems to be a new problem, and I don't like it! Then if I dismiss or delete from history its still not removed! Very annoying and may cause me to ditch Firefox for good!

Hi, I'm using Firefox 125.0.3 64-bit with Linux mint and some of the tiles on the homepage have disappeared I have selected 4 rows in settings but only 2 and a half rows show, I can remove all rows and select 4 rows again but only 2 and a half rows will show all the edit, pin etc, options are there and work and I can rearrange the tiles but if I dismiss a tile it disappears completely, any help much appreciated. please see added image.

A few days ago I started having an issue where Youtube videos 1440p and up would frequently skip ahead, stutter or freeze and play audio only. They also stopped loading as quickly as they had before. This issue only happens in Firefox as when I watch Youtube on Chrome everything is fine. I've tried disabling extensions to no effect. Is this a known issue or does anyone have suggestions?

Hi Lots of my files on Mac have converted to Firefox (which I don't use) and will not open either in Mac, Adobe or Firefox. They are showing in my icloud drive but I cannot open them. And I REALLY need them as they are the source files for a website. I have no idea why this has happened, but would love some advice on how to fix it. I don't ever intend to use Firefox so not quite sure how it happened. Many thanks

I've always had my firefox checkmark the "Always ask you where to save files" box. I started to download a file from Envato elements, and firefox asked me where I wanted to put it, so I pointed it to a dropbox folder on my finder level (I'm on a Mac computer). Some pop up showed up that said it didnt like the directory so I hit ok. Then I tried to download again to another location but now firefox won't ask me where i want to download the file to. And instead it just populates a file in the downloads folder called "7gp69ST8.mp4.part" or something similar. If I uncheck "Always ask you where to save files", the whole file downloads just fine to the downloads folder but I dont want that setting, I want the check mark ON so that it asks me each time where to save the file to. But its not asking me any more. So I hit quit on firefox and came back in and the issue persisted. I cleared the cookies and the issue persisted. Please help me fix this.

you dont need a screenshot. its reral simple i am tired of nothing working right. i have added multiple wallets on my phantom app but it doesnt show up on my phantom wallet on my laptop. i have been hitting check for updates for 2 hours. why wont it update. and if i have to put in a 24 word secret phrase evertime i want to update my extension. then good bye firefox. then why have a check fofr updates button.

There seems to be something specific to the Phlearn site and Firefox which prevents videos from auto advancing. They either recommence the just completed video or revert to an earlier one.

Hi there!

I'm trying to troubleshoot why firefox isn't connecting to my DNS over HTTPS instance running adguard home. Every other device (including another laptop) is able to set the DNS over HTTPS and connect successfully - but my desktop PC instance gets NS_ERROR_CONNECTION_REFUSED. Despite multiple reboots, ipconfig /flushdns, release/renew, etc...

Even my android phone is able to connect to it using the "private dns" feature (uses port 853 instead of 443).

I've been able to verify https access to the DNS server and it's querying successfully. It's just this one instance it won't connect.

Windows 10. Weird glitch.

If I use Wondershare UniConverter's downloader function to download a video, as soon as the download starts, all Firefox open windows close. This is a recent thing, the last couple of weeks or so. I have reinstalled Firefox and UniConverter. The first time I tried it after reinstalling UniConverter, all was well. But the same issue has shown up again. I have tried rebooting my PC to no effect.

Any bright ideas welcome!

I have scoured the web and read/tried everything. I cannot remove the time and date stamp from my documents. No matter what program/app they are printed from it shows up ruining my printing. I've tried unchecking the header/footer box. There's nothing in my brother printer set up regarding the date/time stamp. It has to be firefox. How do I fix this? I'm not a computer guru so I need details. I'm at my whits end! Thanks!
