Firefox Community Forum

I am running an iMac that is about eight years old.This afternoon my Firefox browser was taken over by a "warning" from "MacOS security center" that I should go to THEIR macOS support site to get my system unfrozen. The number they give is 1-877-xxx-xxxx. I cannot get this intruder to go away, even by restarting the computer.

Hello, After the last MacBook Pro M4 update my tabs keep disappearing. This is quite ANNOYING as I use ALL my tabs. Plus when I go to HISTORY there is NO Restore Previous session...so I am losing EVERYTHING. Do I just need to go out to another browser and make them my default? I can find NO help when I go out to your support for my problem. Thank you, Patty

/edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have macOS.

All of a sudden I am not able to download files on my MacbookPro in Firefox. I am using Version 126 on Mac OS 12.7.5 Monterey.

Downloads are working if I use Safari, but I do not use it. I just used it for testing purposes. Is anybody else having this problem? I've already "refreshed" Firefox per their suggestion.

Hi, I installed the latest iOS update yesterday and afterwards my firefox was mush. I tried reinstalling it already. The symptoms are as following: - can no longer use my 1password extension - YouTube and LinkedIn doesn't load at all anymore - For my agency tool Moco I can see most of the page but the menu is totally hidden to me...

Anyone any ideas what is happening?

Hello, I have a MAC computer. For some reason, when FIREFOX made its newest update, I can no longer watch videos on YouTube. The video will start but then give me the death circle, and it will not come out of it unless I click just a slight distance away on the timeline of the video. Then, the video will go for about 20 seconds and do the same thing. I continually have to click on the timeline in front of where it stopped when the video stops, and then it will give me about 20 more seconds of the video before the white arrow circle shows up again. You can wait all day for the circle, but it will not start again unless you click on the timeline again ahead of where it froze.

When I am working with several open applications I sometimes need to slide the browser window over to I can see both open apps at once. Now when i pull the browser window partially off screen to the right it bounces back at full size. This is frustrating and time consuming to resize again. is there a setting to turn this feature off?

I use a 2009 Mac Mini running OS 10.11.6 dedicated for streaming. I was prompted to update Firefox to ESR which I did, replacing the older version of Firefox. The new version will not open.

It was the only browser I had. Can I undo the installation? Or download 78.15.0 somehow to restore the functionality of this Mac?

I have not noticed this before upgrading my Mac to Sequoia 15.0, using latest Firefox browser update, but "printing to PDF" which I used in the past extensively, makes a PDF file that causes the letters to be one ASCII number off. So if I type into the "search" field "p", then all the "o's" are highlighted. I can only enter a search term if I usean "ASCII number +1" technique, so I can search for "get" by typing in "fds". Numbers are searched for as in the past. This is not happening if I make a PDF using my Safari browser, all the PDF words are correct and searchable as in the past. Anyone have insights as to why this might be occurring? I will try restarting in "safe" mode and re-downloading Firefox as is suggested in some of the articles here. Thanks!

Firefox is creating very high CPU use with many WebThumbnailExtension Web Connect processes. The processes disappear after shutting down Firefox and other programs that access the internet. Does anyone have an answer on how to prevent this from happening?

MacBook Pro M4 with MacOS Sequoia 15.3.1

Yesterday I could access my passwords saved in Firefox, but today there were only two & those were in an open window for passwords. How can I recover my list of passwords, please? I'm using a MacBook Air with an M3 chip, Sequoia 15.3.1 Thanks so much!

It used to be that Firefox had different containers. I kept separate ones for shopping, banking, Facebook, etc. Now I had to erase my MacBook Pro IOS, and after a few days of trying to use Safari, I installed Firefox. But I can no longer see the possibility of using containers. I found them particuarly helpful when I had more than one account for a certain platform - with containers, I didn't need to sign out and sign in to switch users. It also (supposedly) kept Facebook from tracking our interests. Has Firefox done away with containers? Or have I simply forgotten what they are called (buckets, maybe?). I searched and searched the help articles to no avail. If they have done away with them, why?

By the way, Chrome (which I had to use at work) started offering a similar product and it was also very helpful.

Hi,

I've been getting a glitch while typing emails in Outlook Web Access for the last couple of days where superscript type in dates looks like the image attached. It was working fine until sometime this week. I've tried using Microsoft Edge and the issue doesn't happen so I'm thinking it might be browser specific.

I'm running Firefox Version 135.0.1 (aarch64) on a Mac Studio with Sequoia 15.3.1 (24D70).

Can you advise please?

Thank you very much.

Calum.
