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.

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

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 ?

I have an issue with Firefox 127 not accepting a session cookie that I use for user authentication. I have an ASP.NET application with a login form that includes fields for login and password, and a submit button. When the button is clicked, an HTTPS/POST request is sent to the server. The server responds and sends back a session cookie named .Cookie.Name with the parameter httpOnly set to true.

When I check in Firefox's Developer Tools under the Network tab, I can see .Cookie.Name in the server response. However, in the Developer Tools under the Storage tab, .Cookie.Name is missing, which prevents the user from logging in. This problem does not occur in other browsers like Chrome or Edge, nor does it occur in Firefox version 126. The configurations for Firefox 126 and 127 are identical.

Could you please assist with this issue?

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.

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...??!!

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?

I'm having problems logging into any/all Wordpress dashboards following the latest Firefox (V127) update. The 'verifying' screen continues to cycle but doesn't produce the login screen. I can get them to work in Troubleshooting Mode. This also works when the 'New Tab Override' Add-on is disabled too. I've tried ALL of the recommended custom tab plugins with the same results, so it suggests a common incompatibility.

Have cleared cookies and browser cache. WP login works on all other browsers.

Would be grateful for any help and/or suggestions.

Firefox works only in troubleshoot mode, and will not copy and paste, I tried and deleted and re-installed, no change, is there a way to run a diagnostic? . other browsers are fine.

I regularly play Bejeweled Blitz on FaceBook but I cannot use Firefox to play because if I try I get the message to Upgrade to the latest version of Flash. Well Flash has not been used in many years but I still get that message on Firefox. I can easily play on three other browsers without receiving that message. I have switched from Firefox for that reason but I really would prefer Firefox as my default browser. What can I do? Yes, I am using the most current version of Firefox 127.0 (64 bit). My extensions are AdBlock+, Gmail mail checker. That's it. The same thing happens in troubleshooting mode too. I am using Windows 11. Please, suggestions are welcome.

FF just updated to 127. Every time I open it I get the whole intro shebang about migrating, extensions, etc. When I finally get to "Start Browsing" none of my tabs or bookmarks will load. I have cleared the cache, tried reinstall and no change. What's next, please?

TIA Toby

How can I change the defalt filename of inserted image from clipboard? I use firefox with local interface language but I don't want it to influence on filename of inserted images. I don't wanna give any clues in work chats, forums etc. which language I use in my browser.

Can you tell me why gmail is recently (within the past 2 months) showing that Firefox has authorized access to my gmail account? It is sometimes showing up as accessing the account minutes before I even log in. It never did this before, but I use a security key to access my gmail account--could this be causing it? The security key mfr says there is no way it can be the key causing this and suggested contacting Firefox. I have reinstalled Firefox and the same thing happens. I have never given Firefox or any other application access to my gmail account. Thank you for any answers you can provide.
