Firefox Support Forum

Hi,

I've been using firefox for 10 years and this is the first time this is happening on me. Firefox was working fine but it does not work starting yesterday, simple task like opening and starting a new tab firefox took more than 20 seconds. None of the pages are showing anything, even those about:config pages are not working Every other browsers, like safari and chrome is working perfectly.

I tried to refresh, reset, safe mode, uninstall and deleted library/caches/firefox, library/application support/firefox, but the same problem still occurs.

My specs: macos 14.1. intel 13900kf, 6800xt, corsair vengeance ddr5 48gb, wd 850x ssd

Here is what is showing in terminal. Thank you.

Is there some way to enable and disable specific config settings , on a per-site basis?

For example, let's say I want to disable right-click hijacking (dom.event.contextmenu.enabled) on turtlesaregreat.com, but use the default settings everywhere else.

The Page Info > Permissions panel has some, but not all the ones I want. Is this somehow built into Firefox, or maybe there's an extension?

Thanks.

I used to access RAI (Italian TV) no problem until I upgraded my op system to Ventura 13.6.4 two days ago. Now when I try to log in to RAI from Firefox (latest version) I get the following message from the RAI system "window.gigya is undefined" . Even though my credentials are correct, the RAI platform does not allow me to log in to my account. This is a Firefox issue and not a RAI issue. I know this because I can access my RAI account and see TV content no problem via SAFARI. Perhaps there is a setting in Firefox I need to change. At the moment I am using Firefox with the standard settings (no changes to settings since I reinstalled Firefox in my machine today)

Hi. I keep several Firefox tabs open and active on my laptop. Inevitably, Firefox slows down after a week or several weeks and would benefit from a Quit / Restart. But then (I think) I would lose my tabs, which would mean a trip to the library to login and get them back. If I do nothing, a superslow Firefox will usually mean my laptop eventually restarts on its own. Then when I open Firefox I see a "Restore Session" option, which brings everything back (I think I see Restore Session because the computer did its own shutdown). So, this does work, but I have a slow computer until the laptop does its own restart. I am wondering if I can initiate my own Firefox Quit / Restart which will give me the "Restore Session" option. Thanks!

Last update disabled picture in picture mode -- on top of full scree applications.

Please advise how to correct / adjust. This feature is vital to my work.

Thank you for your time and help.

I have the latest version of Firefox (124.0.1) that I'm using on macOS (14.4). The problem is that the whole top section of the browser (tab bar, location bar, and bookmarks bar) is dimmed out a lot of the time. Including when the browser has desktop focus. This, as you might imagine, is very annoying.

Don't know what's changed, I haven't done anything to Firefox that would make this happen. Wondering if this is a bug in the latest version that will be fixed, or if I need to pursue this. My plan would be to log out of my Mozilla account on the browser, reset all the settings, then log back into my Mozilla account in the hopes that this is something that won't survive that process; i.e. not saved in my saved settings.

I'm about at the point of stopping use of Firefox, which I really don't want to do, if I can't fix this due to eyestrain from squinting at dimmed tabs, etc. If this is a release-related problem, I can put up with it until it's fixed.

I'm getting the error message "No video with supported format and MIME type found" with mp3 files at https://www.gatherthepeople.org/test/styled-7/page-3/ when using Firefox 123.0 on my M1 (ARM) iMac running OS 14.3.1; when using Firefox 123.0 on my M1 (ARM) MacBook Air running OS 14.3.1; when using Firefox 123.0 on Win 11;and when using Firefox 115.8 on my Intel MacBook Pro running OS 10.14.6.

The same mp3 files (https://www.gatherthepeople.org/test/styled-7/page-3) play without any problem with Chrome and Safari on the Mac and with Edge on Win 11 .

Thanks

About a week ago I started getting these update error messages stating "Update available - Firefox couldn't update automatically. Download the new version". I've also tried clicking "Learn more" on the error message but it's a dead link. Going into the settings for updates I am set to auto update, but when I manually check for updates it says "Failed to check for updates".

The help article on this issue simply tells you to download and manually reinstall Firefox, but I'm having to do this nearly every day. I work in IT myself so I know a "bandaid" workaround when I see one. Is there a solution to this issue?

I recently started using Firefox as my main browser after using Chrome for awhile, and I'm now running into trouble playing music on Spotify.

Every time I try to play a song on the browser version of Spotify, it cycles through several quickly without playing anything and eventually displays an error message that says: "Spotify can't play this right now. If you have the file on your computer you can import it."

I've seen others with similar issues (https://support.mozilla.org/en-US/questions/1431659) but the suggested fixes aren't working for me. My Firefox is up-to-date, I have DRM controlled content enabled, as well as the Widevine Content Decryption Module.

Looking for any suggestions!

There is this new pop up coming on latest firefox version 123 about opening favorite link on firefox, I want to get rid of it programmatically using java, which argument or preference should I use ?

For some reason my Firefox on my Mac and Windows computer won't sync even though I am using the same account. I would like my Mac to look the same as my Windows computer. I have tried logging in and logging out on both, all the basic fixes but nothing has helped.

Thanks.

In my location, my only option for internet access is a mobile hotspot with limited data. Consequently, I am always mindful of my data usage when using my laptop. Despite primarily browsing static pages, email, and other low-data activities, I often find my data usage higher than anticipated. The main culprit comes to mind to be videos embedded in news articles. Sometimes, with multiple tabs open, I switch to an inactive tab only to find a video playing. Although I've configured my Firefox preferences not to autoplay videos, it seems that YouTube videos still override these settings.

So, my question is, when a tab is inactive, does Firefox stop all data transfer for that tab in the background? And if not, what are the solutions to stop any background data other than continually closing all tabs?

Also, any suggestions on this topic are appreciated, especially from and to users who also live in remote areas without fiber, DSL, etc.

Safari has no problem with https://meijer.com, but Firefox flags it as untrustworthy and won't let me connect. I am using Avast! antivirus. Brave browser also works. I am using 124.0.1. I see there is a 124.0.2. I'll try that next.
