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?

I'm trying to get my Firefox installation to permanently disable private browsing mode, however, all information I can find is for the Snap version of Firefox, and not for the Flatpak version. How do I disable private browsing on my installation?

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 115.12esr slow to startup takes up to 10 second to load the first time now Firefox was fine in version 112.esr. to bad Firefox forces updates, even when the update make Firefox worse. https://snipboard.io/QF0ERT.jpg of course it works faster without extensions, that does not mean anything. I would reinstall the older version but Mozilla fixed so we cannot. I do not have time to reinstall all the extension so I am left with a useless Firefox. To bad Firefox does not allow reinstall of extension automatically, a reset of Firefox would also make Firefox useless; I am at a loss to how to continue to support Mozilla and not switch to another browser?

I just asked a question about email not downloading to thunderbird and got an answer which I think meant that this was not the place to ask. I cannot find an open question place in Thunderbird. Where can I get support?

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 ?

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?

I went to the trouble shooting site after asking my question about Thunderbird. It was suggested that running two firefox clean ups was a good idea. Now my ribbon thread is not present. I have to jump through hoops to find bookmarks, etc. This makes all navigation difficult. Is there a way to get the old data on the page in the old form? The data folder is on my desk top. I feel stupid because the trouble shooting site said all would be saved. How and where?

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.
