Firefox Support Forum

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

Hi, I have applied the latest updates on my Zimbra server (Ubuntu 20.04) last week and since then the emails contents are not displayed anymore in the classic web client, they are displayed only in the modern web client, I will attach same email in both clients to compare. In using Google Chrome there is no such issue

I found my old password Firefox recovery key after I already changed my password and got a new recovery key. Can I use my old recovery key to get back all the things (eg bookmarks) that may have gone missing with the switch to a new password?

Below is the content-security-policy Firefox loads for chatGPT:

Notice that it includes " frame-ancestors chrome-extension://iaiigpefkbhgjcmcmffmfkpmhemdhdnj"

Would this extension be installed in the computer, kind of like the extensions that are loaded from Chrome (i.e., C:\Users\myUser\AppData\Local\Google\Chrome\User Data\extensions_crx_cache)?

Thanx

Firefox on Windows 10 desk top suddenly stopped working with error message

XUL Runner Error. platform version 127.0.1 not compatible with Min version >= 127.0 Max version <=127.0

N.B. This is another machine - not this lap top

Please advise

Hi,

For some time now, when I download a .pptx, .xlsx og .docx Firefox changes the file format to .pdf when downloading the file. I then have to manually choose the correct app for opening the file, overrule error messages and delete the ".pdf" when re-saving the file even though it recognises it is not really a pdf file.

I've tried to change the Firefox settings, clearing cache, restarting or deleting in config and other small attempts to reboot whatever suddenly started to cause this problem. As far as I can see, it is not an unknown issue, but I've not yet been able to find a solution to my problem, which is getting on my nerves.

Hope you can be of help.

I maintain application that uses OWIN Microsoft library for authentication. It uses .AspNet.Cookies to pass auth information. For unknown reasons I see that Firefox 127 rejects that cookie. I've tried with SameSite Lax/None/Strict and Secure param but no results. Previous versions and other browsers ( Chrome, Edge Safari ) woks fine. Any idea ?

Firefox 115.11.0esr from openSuse doesn't display a status bar at the bottom of the window. How can I restore this feature to display the actual URL of a "link" under the cursor, as in Thunderbird?

I am using Firefox version 126.0.1 (64-bit) on MacOS Ventura 13.0. I cannot interact with any Nature journal webpages (https://www.nature.com/ , https://www.nature.com/neuro/ , etc). I can only scroll, no clicking on links, highlighting or anything else you might expect. Not sure if this is specific to my computer/browser/extensions or if others are experiencing this and what steps I might take to resolve?

So I just downloaded Firefox update and it wiped out all my open tabs ... very very inconvenient for me! Been using firefox for a long time and that never happened before. Some warning would have been nice.

Since the latest update Firefox doesn't show up in the browser list. I don't want to uninstall to reinstall because I have too many settings in my browser that I don't wish to reset. Please solve the problem.

I use my local ISP for email service and tech support chk'd and there are no current issues with their email service. When Bitwarden is turned on and I open an email, none of the text in the reading panel of the email will show up. The "subject" header is readable, along with the words 'from' and 'to', but no text after them. The entire reading pane where the email text should be is blank. As soon as I turn Bitwarden off, I read read ALL the email text...??!!

Regards, Laurie

Recently, I cleared the cookies and site data from my browser as I'd noticed they were taking quite of lot of space on my harddrive. I thought clearing them would just reset them, but it looks like they were completely wiped instead.

Now, the browser never remembers any login information, so I have to connect to every site I use everytime I open my computer. It's troublesome when some of them have double verification and I have to go through the trouble of checking my email and entering a code everytime. The websites don't ask me to enable cookies again, so I don't know how to make them remember my informations again.

Is there a way to re-enable cookies, or have the websites ask me to enable cookies again?

My workplace bans Firefox. It is not possible to install it in any way on any computer. I still use Firefox on all of my personal devices, and heavily utilize the Firefox Sync to keep my Bookmarks in sync across devices. I need to be able to access my Firefox Bookmarks somehow from my work computer, so I can at least retrieve recently bookmarked items.

I am able to log in to my Firefox Account https://www.mozilla.org/en-US/account/ and see my Firefox account details, but this does not include any of my Sync data.

How can I access the contents of my Sync data? I do not even need it to be integrated into another browser, I just need to be able to access it somehow from a computer that is not able to have Firefox installed.

There is a similar question here https://support.mozilla.org/en-US/questions/1255784 which provides a non-functional non-answer which is not appropriate and does not work.

I am writing to request assistance with recovering my deleted browsing history for my Firefox account. On June 18, 2024, I accidentally deleted my browsing history and I am hoping there is a way to restore it.
