This will be a long question and in 2 parts, so I'll apologize up front.

1. I am running FireFox on my 11-year old MacBook and love it (MacOS Mojave version 10.14.6). However, my printer just crapped out, and my new HP 9120e requires MacOS Big Sur (11.x.x) or later. If I update to that OS, will I still be able to use FireFox? If so, where do I find it (see Question 2, below)?

2. Since my old MacBook is clearly reaching the end of it's life and my Excel and Word apps are also ancient, I am trying to transfer all my stuff onto a "New" MacBook that is running MacOS Monterey version 12.0.1. However, the "New" computer (I will not say "improved") has been a reliability nightmare and I just had it in for service. They wiped my disk clean to install the Monterey OS. So, other than Safari, I have no browser (or anything else for that matter). When I go to the App Store to download FireFox, and don't see it anywhere. Help!

I am using the Firefox browser on my iMac. Suddenly, I am not able to 'sign in' or access pages of common websites. I am getting blank pages or pages with the ever-circling ball when trying to access websites, like homedepot.com, shutterfly.com, etc. I can access them via safari.

I have gone through the Troubleshooting steps, have Uninstalled Firefox and Reinstalled, etc. What is happening with my browser?

I’ve been using Firefox on my Mac without any issues, but I recently had to erase and reset my Mac. After reinstalling Firefox and attempting to sign in to my account, I am unable to sync my data.

When I click “Sign in” and enter my password, I successfully log in. However, it immediately returns to the message “Please sign in to reconnect,” and I am unable to proceed with syncing.

This is the first time I’ve encountered this issue.

On a positive note, I can still see my organized bookmarks on Firefox for iPhone, which were synced from my Mac before the reset.

After recent update bookmarks disappeared. When I restore them and then close firefox developer edition the bookmarks toolbar is gone again. It seems like a bug in that recent update. Please advise.

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 tried to print directly from a website, but it will not print. If I print an image or PDF, it will print just fine. I am currently using Firefox 135.0.1 on a macOS Sequoia 15.3.

I have the last Firefox version and am trying to add extensions (e.g. video download helper). When I click on Add to Firefox, it works at loading the extension, but without any success. The blue dot in the gray square dances and dances and dances.... Thanks !!

Using iOS on Mac Mini desktop, I get no sound on democracynow.org but on the iPhone the sound works fine. Most other streams/videos have fine sound but not imdb.com on the desktop with iOS but again, fine on the iPhone.

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!

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'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?

I want to download and install Firefox on my new iMac. As administrator it downloads but the instellation won't run. As a user it downloads and I can move the icon into the application folder. Firefox then opens but it won't run. Everything is frozen. What is going on??

I accidentally downloaded a newer version of Firefox on my iMac but it is too old to run it. Now I have no way to download an older version that I use to have. Don’t have any suggestions? Thanks

ad blocker on mac laptop does now show up in mozilla firefox extensions or manager, I opened the puzzle icon but only grammerly shows up, I know I have ad blocker because i have websites saying so and i paid for it annually,

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.
