When attempting to update my Mozilla account from my Firefox settings, I was unable to add my secondary email address because of an error message stating that the secondary email account exists...

Repeating this action in case of a bug resulted in being locked out of that particular window.

I have no idea what that error message means, nor how to circumnavigate it. Please help!

Thanks, MGB

Whenever I navigate in a video or go fullscreen on YouTube there's a painfully loud crackle, I use the site frequently so I'd appreciate a fix because it's very painful for my ears.

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Hi, I got a new laptop recently and ever since then I've been experiencing this problem. Websites like https://tabs.ultimate-guitar.com or https://ukutabs.com offer the option to autoscroll, so that you can play your instrument without having to pause your playing and scroll further yourself. This feature hasn't been working for me ever since I got my new device and since it's various sites, I suppose the problem must be in the browser itself, I just can't figure it out. In the case of Ultimate Guitar, when I click autoscroll, it does move slightly, once, but then stops again, and you'd miss the movement if you're not paying close attention. I can switch between various speeds on this site as well, but it doesn't do anything. In case of Ukutabs, there's not even any kind of response from the site when I click the option. I tried turning on and off Firefox settings concerning autoscrolling and smooth scrolling, but nothing solved my problem.

Thank you for your time and energy, everyone!

Themes do not stay locked since several updates back. It is ridiculous that every time you open the browser you need to go to settings and get 'dark theme' back on, when it is the only theme many of us with visual problems can use. MANY people have complained about this (read your own reviews). FIX IT! It's doubtless a five minute job to put this back the way it was.

Suddenly stopped receiving emails on my blueyonder account 6 days ago. I can receive them fine on my iphone and ipad and with virgins web mail site but nothing on Thunderbird. It keeps asking for my password but does not recognise anything that i type in. Also will not send from blueyonder. My gmail account works fine. Please help

I find that OneNote Web Clipper extension is not available for Firefox now. I'm sure it used to be. Why is it not available and is there a workaround to be able to use it still in FF? Windows 11.

I would like to know how I can middle click with my scroll wheel to open a bookmark in a new tab, but not be dumped straight into that new tab. I like opening multiple tabs at once before going into them.

Is there a Firefox setting that automatically clears cookies? When I turned my computer on, it had been cleared of cookies since the last time I had it on a few hours ago, but I didn't do it. No one else here to use the computer but me. I don't want cookies cleared automatically. How do I change it back to manual? I use Firefox Browser 120.0

thank you

hi Team,

We are working on xxx organization and for one of our core applications experienced suspicious activity since November 22, 2023, while users leveraging Firefox browser version 119.0 where customer made multiple attempts to perform sequence of flow and got dropped. Around 99% of our customer got dropped ever since Nov 22. We are not sure if its due browser or any other suspicious issue.

however, we would like to understand from your other customer experience perspective, have we encountered any bad user experience using Firefox browser version 119.0 / or do we have any bug encountered and recently had a fix? 

2. Another question, If in case was a fix for Firefox version 119.0 will the customer browser automatically gets updated ?

It would be great if you can help us to share these details so that we can investigate further.

I've lost all my open tabs....and I can see them in history, but when I open any historical item,...it loads it over the top of the only open tab I now have...as a result I only have one tab. Its a mess what have you done?

When I have to change a setting on my LAN printer, an HP, I should be able to access its built-in settings module. Firefox will not let me access the printer because it doesn't have a trusted certificate.

So I get a blank page with the message: "we could not verify the certificate: reason = untrusted" and doesn't give me any options. In versions past, I recall an option to connect anyway if I trusted the site.

If there is a setting that lets me enable the option to continue anyway, where is it? Alternately, is there an exception list, perhaps by IP address, that will allow the browser to connect? Perhaps another solution?

I can't be the only one who is encountering this issue.

Thanks,

Ed

Hello, the description is the same as in the title: Firefox is slowing down significantly while I have "more" demanding games running I'm talking about a game like assassin's creed mirage mostly on ultra for example.

It all started with the purchase of a new computer, on the previous one I did not encounter such a problem. It manifests itself in the way that the video is slightly desynchronized with the sound + I can see a significant difference (delay) when scrolling the pages.

My current rig: Intel Core i7-14700KF Nvidia RTX 4080 32GB of ram running at 6000mhz (G Skill Intl F5-7200J3445G162x16GB ) 2x Kingston SKC3000D2048G 2TB

I understand that the GPU focuses on the game but can't it be improved somehow? The rest of the applications on the computer work normally In my opinion, the computer does not seem so weak that it cannot handle Firefox and the game simultaneously.

Send help please 😊
