Power consumption of Firefox is so high that it nearly killed the display of my iMac. My screen started flickering with horizontal lines across the display. When i touched the screen, it was so hot that I could boil water using it. I did not realize that it was Firefox that was killing my PC until I looked at the power consumption (see the attached screenshot). I hope there is a solution to this since I really love Firefox and have been using it for well over a decade.

When I open FF 137 on my iMac running OS 12.7.6, it just keep trying and trying with no link. When I try and quit it needs to be forced quick to stop running. There are no fire walls and it worked yesterday 4-5-25 just fine, but no go today. I tried replacing FF and still no luck, what do I try now, [email removed]@yahoo.com

Hi,

On MacOS, in order to set keyboard shortcut, I need to know the exact name for the feature. But I can't find tab navigations in Firefox's menu.

For example, in Chrome, they have a menu called "Tab" and there is "Select Next Tab" and "Select Previous Tab" in the menu. That are the names I need to set keyboard shortcut. But I can't find the equivalent in Firefox.

From the screenshot, the keyboard shortcut works for Chrome, but not working for Firefox as I don't have the exact name for tab navigation.

I recently updated my wife's computer to an Apple Mac Mini M4 running iOS 15.4. Everything seemed to be working fine including Firefox until yesterday when Firefox update box popped up. She did as she normally has for years of using Firefox and clicked the restart for update button . FF restarted and popped up with 2 dialog boxes one asking to check network for there devices which she click "Don't Allow", she only uses that computer no smart phone etc. Then a second dialog box asking for an admin login and password to install something else I put in my admin login and password clicked continue it doesn't seem to do anything except lock up Firefox to the point I have had to re-install her user from a time machine backup 2 times in 2 days. I tried installing a new copy of Firefox that will launch the issue is she's used Firefox for probably 10 yrs so there are ten years of bookmarks and logins and passwords saved in the original copy of Firefox that will no longer boot unless I do a complete user re-install from a time machine backup.

Please help, how can I fix this problem?

I believe I am still using the first , I don't know. I am up to date. Does that mean I am running 2? I don't think, as I have 2 FF. symbols in dock(identical and conflicting I think). I tried to delete first version unsuccessfully and when I restart comp. from start I have to be prompted to set up again. My NordVpn account was doing the same tying with their Protection pro* (removed it- Ok now) . I have had FF #2 on comp. for a long time and I think I'm now just waiting to sign in now as I don't have FF PW-not problem. Making sure if I sign in to FF2 I won't loose my saved FF info... What should I do ? The SH. attached shows both FF's in desktop and Dock.Need guidance - Thanks a lot. Jon D.

Hello, today I could not launch Firefox on my Mac. Because this is a corporate machine from Kyndryl, I downloaded from Kyndryl App Store, I have rebooted the systems, I have updated iOS to last version, but still haven't solved the issue. This is the situation: Firefox is installed, I click to launch it, I am asked to authenticate with MFA I authenticate correctly, and Firefox just sits at the dock bar jumping, then stops jumping, and nothing else happens. I repeated the process several times, made several reboots, nothing changed. Can you suggest a solution?

I have a MacBook Pro running Sequoia 15.3.2. When I remove all data from Firefox (137.0 (aarch64)) in Manage Data under Privacy & Security there is one site datum that always returns. It is 64k of data, 0 cookies, that persists after every clean up. This has been going on for quite a while.

I've searched Finder for any reference to the company name and cannot find any reference.

It isn't a lot of data, but I'd prefer to not have something lingering around.

Does anyone have a suggestion for how to delete this once and for all?

So, I just now installed Firefox and now I want to change the background of the home page (new tab), the same way you would do in chrome. I did some research and created a chrome folder and a chromeContent.css file in there.

I tried first the code in this link: https://support.mozilla.org/en-US/questions/1271362 and then this one: https://superuser.com/questions/1495946/how-do-i-change-the-background-image-of-home-page-in-firefox

neither of those worked, even though I'm pretty sure I followed all of the instructions correctly. help please, will be greatly appreciated (i don't know if i chose the correct topic)

pictures included in order: the code (device name crossed out), inside the chrome folder, inside the profiles folder

I recently was unable to have my audio and video function while in an invited Google Meet meeting. I use a Mac OS, Sequoia 15.3.2 (24D81), Firefox 137.0.1 (64-bit), and latest Google Meet.

I use Firefox's "Strict" privacy settings and could use some instructions on how to allow Google Meets to function properly on Firefox. For example, I have turned on the browser window toggles to allow the site special permissions - but still cannot get the Meet Audio and Video settings at the bottom to toggle on (see screenshots), the message is a grayed-out "permission needed". I cannot figure out where the permission needed is located...Is this a Firefox, Google Meet or somehow my Mac. Sending this to Google as well.

Thank you

My Bookmarks Toolbar is set to "Always Show." With the last update, all of them disappeared.

All of my Bookmarks disappeared, but the bookmarks in the toolbar are the most heartbreaking.

Firefox is only offering to import them from Chrome. I have been using Firefox for years, and this hurts a lot.

For some reason after a few (sometimes only 1) use of "copy/paste" stops working. I'm running the current version Firefox 137.0 (aarch 64) on an Apple M1 desktop running Sequoia 15.3.2

For example if I highlight a webpage URL and copy, then try to pase (in an email message for example) all the fields are grayed out, paste is not available as a choice. So I try Command-V and no joy.

this occurs frequently but not always, and usually into a session online of a few minutes or more, the problem never occurs using Chrome

If I restart the computer, that sometimes fixes the problem, but often does not.

So wierd

I'm using Mac OS 11.7.10. Firefox desktop no longer allows me to browse the internet. It just keeps spinning wheels. I've downloaded the newest version and it still crashes. What can I do?

Hello,

I would like to know if it's planned that Firefox uses macOS abilities like on Safari, such as text replacement and others ?

Kind regards

Hello. I have been having this issue recently with Firefox where, when I Google things and open up Google Images, I am unable to open any photos. No matter how many times I press on the mousepad, I cannot open up an image in Google Images unless I go to the website that image is linked too. Something else is that I cannot open an image in my Google Drive. I am resorted to download the file. I trouble started Firefox today to see if that would work, and it did, but I noticed this problems started up again. I just need some help or direction of what to do from here.
