Firefox Support Forum

I've been using a Rewards site regularly (3/4 times per month) for several years without problem. This weekend the attached pop-up appeared. It makes no difference whether I select Resend or Cancel, the program just re-displays the pop-up trapping me in an endless loop. The only exit is to close the window and abort the process. I was able to complete the task without any problem using Edge instead so it appears to be a Firefox specific issue. I haven't consciously changed anything since last using the site successfully on 24 May. Any help/suggestions appreciated.

In my settings under Connected Services there is a list of devices that have signed into my firefox account. I do not recognize one of them. The Connected Service listed name is Firefox Mobile 126, Android 14. How can I find out where this is coming from?

Thank you

Firefox recently 'crashed' on my desktop PC. It asked me to restart in safe mode or restore to the original state. I chose to restore. This meant that I had to re-add all of my add-ons and log back into my favourite sites as my log-in details had disappeared. I got everything back to normal eventually, except for one very important site. I am now no longer able to log on to my bank website to review my accounts. I get an error message on the site saying " Log on error. You need to enable cookies in your browser to logon to Internet Banking." I have never had this problem before. I am able to log on successfully on my tablet, and also via a different browser on my desktop PC. I'm not a tech expert so this is very frustrating. I've tried clearing cookies/cache/data in the settings but no success. I really need to access my bank accounts on my desktop as I find this easier. Hopefully you can help as I don't want to use a different browser.

Hi, having an issue where new tabs crash while browsing.

Will be fine for 30 minutes or so but opening a new tab/clicking on a bookmark leads to Gah. Your tab just crashed.

Using a working tab is OK as long as I stay on the same site.

All drivers are updated.

Once it happens, I close my browser and I am then fine for a while.

Removed all themes/add-ons in case of conflict but still same issue so re-added.

Any advice appreciated.

Every time I enable Light theme for taskbar it becomes disabled & reverts back to Dark Theme. This is not great for my eyesight. Why does Firefox force dark theme?

The website mylotto.co.nz has been blocking Firefox for many months now and when I rang them to find out what the problem is they just say they are having problems but it was obvious that the person there was reading a script and fobbing me off. This has been going for many months now a problem would have been fixed by now. I would like to know if you can bring pressure to bear on them to get reinstated again. I have attached a screenshot of the message from their site. Thanking you. Murray

When I try to access Developer Community from Visual Studio 2022 ('Send feedback' 'report a problem') the banner displays with selection items but no content is displayed. This has been a problem for several months (years maybe). I now have a problem that I cannot solve and I need to report it and I cannot if content is not displayed.

Hello, Since a couple of weeks I'm facing a strange issue on my Firefox installed on my desktop (arch linux) where the suggestions window that appears when clicking the URL address bar, is shifted upwards and covers the address bar itself and the majority of the bookmarks. Has anyone experienced a similar issue and is able to point me towards some troubleshooting steps? Thanks!

After 10:00 p.m. I cannot get into or use the inter net. I do have an account with you and I thought I could use it at any time to get in to the inter net with security.This started happening about two weeks. How can this problem by solved.

I would like to change my secondary email from 1949.m@sbcglobal.net to yut507@att.net. I am requesting this at this time because I do not know how to contact you to have this done.

I look forward to hearing from you soon and thank you for your time and patience in this matter.

I'm on Windows 11 Pro 23H2. This is a pristine installation, downloaded from mozilla.org, default settings, no add-ons. - Firefox 126.0.1. - There are no cookies, history or cache to clean, since it's a fresh installation. - Connection settings is set default to "Use system proxy settings", although I've also tried setting it up to "No proxy", then restarting Firefox completely, then trying again with a new domain. No change. - DNS over HTTPS is set default to "Default protection". I've also set it to "Off", then restarting Firefox completely, then trying again with a new domain. No change.

I don't what else to try and I don't know what's wrong with Mozilla Firefox.

Can you help?

See video: https://x.com/jdvivar/status/1798859828393332982

Video in Firefox does not run .. no error messages .. nothing. It works fine in other browsers. When I click on the video .. nothing happens. It used to work but not now and I don't think I've changed anything.

Win11 Version 126.0.1 (64-bit)

Ive tried reinstalling firefox because i am not able to download anything with this browser. I thought freshly installing firefox would fix the issue and allow me to download but it didnt. I also am tried to download an addon/extension, and that automatically fails to download. How can i fix this?

A little while ago I noticed that the site I used to test my gamepads (hardwaretester.com/gamepad, formerly known as gamepad-tester.com) stopped working properly. I just assumed this was either something outside of the browser or the website itself was broken. Today I just tested with several other websites and browsers and confirmed that Firefox seems to be the issue. Even in Troubleshooting Mode it was completely broken.

L1, R1, R2, Triangle, Share, Options and the Left Stick seem to be the only things that function properly currently, with the DPad not doing anything and the rest of the face buttons/triggers hitting the wrong buttons. In the case of the right stick, L2 for some reason controls the vertical movement while the physical right stick still works horizontally. This controller works perfectly on the rest of my system, windows sees the proper buttons being pressed and games that support Dualsense work fine without any interference.

Below I have attached two images which show how the website I mentioned used to look, and the second image is how it looks now. I have a feeling some kind of update to Firefox's Gamepad API has broken this, somehow.

previously I added bookmarks to a menu bar at top of firefox. Now I have a bar that displays 2 bookmarks than a >>. I cannot expand this limited display or create a menu to display bookmarks though I can see them by clicking on the >>. Non of the menu suggestions is a fix.

Does anyone know how to control this and get me a more useful bookmarks menu display?

Hi. I am getting vertical lines sometimes. I have included two screen shots. I have checked browser.display.document_color_use = 0, and it was zero. I have tired this in Chrome and it works fine. And I tried in Firefox safe mode, and it still does these strange lines on some websites. I am running Windows 10, and have no other graphic issues except these lines. Websites are Windy.com and google maps. Thanks very much! James

Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

During the past week, my open tabs will crash when I try to open them. All new tabs will crash. There are no crash reports. I cleared my cache but retained cookies. My temporary fix is to close and reopen Firefox. That works until I open another new tab.
