Firefox Support Forum

Hey guys, thanks for the help in advance.

This problem occurred recently and it's quite a pain in the ass. I'm using Macbook Pro 14 inches with M1 Max chip. Lately when I work, I have to open quite many urls at the same time, and my mac went crazy hot because of firefox's insane cpu usage. I tried what's suggested to turn off the acceleration mode, but still, nothing changes.

Is there still anything I can do to resolve it? or I just switch to other browser?

We're exploring the possibility of implementing a mass update for Firefox through backend management, leveraging PowerShell scripts or any applicable method that can streamline the update process for our users.

Additionally, we've encountered instances where users have installed Firefox via local profiles, posing challenges for centralized updates. I'd appreciate any insights or guidance on how we can address this issue effectively to ensure these installations align with our centralized management approach.

I have reinstalled and refreshed the app many times, but whenever I try to search something, it says "An error occurred during a connection to www.google.com. PR_END_OF_FILE_ERROR. This happens with every single search on every website, not just google.

How can I block the dropdown video miniplayer in Firefox 120.0.1 on Windows 11? It doesn't happen in MS Edge.

I've already set the following with no results:

media.autoplay.default = 5 media.autoplay.blocking_policy = 2 media.autoplay.allow-extension-background-pages = false media.autoplay.block-event.enabled = true media.block-autoplay-until-in-foreground = false

Is there a setting that I've missed? Can the miniplayer somehow be blocked using userContent.css? Can the miniplayer be totally removed from Firefox?

Every time I open Firefox, it asks to update. This started two or three days ago, and it's getting annoying. Am I the only one this is happening to? Do I need to remove it and start over?

Dear ladies, dear gentlemen,

on another Computer, when using Firefox, I am now constantly getting a Norton notification of a malicious domain request 22. The problem does NOT arise with the Opera browser installed on the same machine. What shall I do? Uninstall Firefox seems to be the best solution. Scans do not reveal presence of malware. On this computer, similar OP, this does not happen, but I use it much less.

Thanks a lot, Alexander

I recently performed a system reset and upon re downloading Firefox I can't seem to find any of my 50+ tabs that I had open previously, all of them I need for one reason or another, history is empty, can anyone please help explain how to get them back in simple steps?

We write an SDK that needs to detect what subdomain a site is running on. For example to detect that app.foo.example.com.au and web.foo.example.com.au share example.com.au

In order to do that we check if we can set a cookie on `.au` that fails. Then `.com.au` also fails, then `example.com.au` and that succeeds

This is safe and fast and leaks no information not already available to any JS running in the page.

In most browsers this is fine. In Firefox it is also fine _except_ it logs a warning to the console that a cookie was rejected. This then causes users to open a support ticket with us in order to find out about "the error"

Is it possible for us to suppress this log?

Embedded links in Outlook email on Windows 10 will not open automatically when the new email is first opened to be read if Firefox has been selected as the default Browser. This is a new issue !

The message is" if there are problems with how this message is displayed, click HERE to view it in a web browser " and then the Browser used is only Edge!

Restoring disliked Edge to be the default browser corrects the issue but Edge is a known tracking device.

Hello to everybody, My question: Opening local .mdb files (MS Access database) does no longer work in Firefox 120, but was ok in previous releases. The only choice is to save the file rather than onening it with MS access. Under Firefox settings/applications the file type .mdb does not appear. If I answer the question "What should Firefox do with other files?" with "Ask whether to open or save files" it has no effect at all. I expect to find an entry for .mdb files where to choose "always ask" as was the case earlier. Please help!

Still image quality good but videos are over-saturated in colour. Same videos in Chrome videos are not over-saturated. Many people have this issue but no solution in search results.

In the last few months, when clicking on the file icon to download a PDF, the "save as" dialog box does not show up fully and I have to view all windows then click on any open window for the dialog box to appear.

I am on a Mac desktop, running MacOS Monterey 12.6.5 I just updated Firefox, to 120.0.1

I attached an image of what the screen looks like after I click the file icon (top right) to download a PDF. It only shows the "Format" part of the "save as" dialog box until I zoom out to view all the windows then have to click on any open window, then the full dialog box will allow me to choose a location to save and rename.

Any help if this a Firefox issue or a Mac issue?

I have been accessing my Virgin media account for years from the Firefox browser. I like to access my email from Firefox. But now it won't work. However I can get into Virgin media straightforwardly from Microsoft Edge. I've tried clearing the cache (though I don't know if I did correctly) but it's made no difference to the Virgin problem.
