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!

There are reports of conflicts between Firefox performance and Sequoia, how to resolve it? I would like to update from my current MacOS and I‘m not willing to give up Firefox as my primary browser. Could I get advice when it‘s save to update? Best regards RB

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

Firefox has a feature where, if you select a tab and drag your cursor downwards while still pressing down on it, it will open that tab in a new window. Is there any way to disable this? I am frequently opening tabs in new windows when I'm just trying to view them and it drives me mad. I never use this feature intentionally- I am constantly using on accident due to quickly moving my cursor away from the tab bar to view the tab I just opened. Thank you.

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 contacted Apple and they couldn't fix Firefox not working on my MacBook Pro (error: page can’t be displayed, server error). This started after I upgraded to iOS Sequoia 15.0. I disabled my VPN and also reinstalled the Firefox app and it is still not working. Apple says Mozilla may need to release a new update. Please advise what you or I can do to fix the issue. Note: I can access the Firefox page using Safari and Edge so it’s not an internet connection issue.

I used Chrome until two days ago. I just got tired with how shitty the browser was, how bloated it made my computer, and how much Google treats everyone like a data product. However, I use hella google systems from Voice to Chrome to Drive to more and it all worked great together. Choosing to change to Firefox wasn't an easy decision but I knew it was a good one

Which makes it super irritating that some of the functionality is already facing problems. I have shortcuts I built to make it easier to study or do random things so I don't get distracted or tired. One shortcut is clicking a key that should launch UWorld in my default browser & use Lastpass to autologin (I couldn't get it to launch the service but that was a separate issue).

I check if autologin was on for the password on LastPass I've allowed all permissions to the LastPass extension I clear my cookies on UWorld & turned off enhanced tracking protection for the UWorld login portal site

What should I do to fix my one button shortcut again?

I really don't want to go randomly turning off every protection that Firefox gives me to figure it out so I'd appreciate someone who understands the browser better helping me out. Also, bonus points if you can help me build a single shortcut button on my Mac that can launch UWorld & navigate me straight to the question bank. (I do think the issue with autologin on LastPass is going to become more of an issue as I start opening up more websites I used to use on Chrome so I'd rather nip it in the bud before I see the problem occur more often)

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.

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.

Hello,

I have old 15 year old mac el capitan -10.11.r with outdated firefox 78.15.0esr 64-bit.... in perfect condition. Unfortunately I can not make updates on browser anymore. Online banking websites does not allow me to use this outdated browser. Would you be so kind to make even paid update for me? Or at least let me know what settings I should change under about:config

Waiting to hear from you! [edited email from public]

I have been unable to use Firefox for Gmail for several years now. I use Chrome instead, because whenever I try it on Firefox, I get the following message: Do you really want to use HTML Gmail? You're about to use a version of Gmail designed for slower connections and legacy browsers. To get all of Gmail's features, including inbox categories, images and quick actions, please use the latest version of Gmail (recommended). When I click on the box marked Take me to the latest version, absolutely nothing happens. If I click on the box for the HTML version, Gmail appears, but devoid of anything resembling Gmail as we know it now. Much as I want to use Firefox for everything, I can't, because this is a serious limitation. Am I alone with this problem? It has happened on two different laptops (Macbooks).

Hi, as the title says, they stopped displaying after I installed the latest update for firefox for my computer (macbook air with the apple M1 chip). I have checked that in the settings I have "Show an image preview when you hover on a tab" enabled and that in my config I have both browser.tabs.hoverPreview.enabled and browser.tabs.hoverPreview.showThumbnails set to true. What could the issue possibly be now?

Since the latest update to my Firefox, videos (for example, in documents such as surveys) either do not load or they freeze. And in some streaming applications, either they play with no sound or when sound is turned on the video freezes. This was never a problem until recently. iMac desktop (2017) Ventura 13.7.4 Firefox 136.0.2 (64 bit) The same issue does not occur on Safari or on my iPad (using Firefox). Any advice?? Thanks.

On my phone, both passwords from Firefox and iCloud auto fill into my browser, but on Mac I do not see anything besides the Firefox ones. I keep my most up-to-date passwords in iCloud, but would love to use auto fill in Firefox as I am not a fan of Safari. Is there a way to set this up?

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

Multi-Account Tab is on longer loading. I uninstalled it, shutdown my computer, and restarted it, reloaded it back on. Unfortunately, it's still not working. I do have Tab Stash on my computer as well, and it not working either. I guess the two problems are related, but I thought I would start with Multi-Account because I didn't want to lose all my bookmarks.

Does anyone have any thoughts on how it fit this?

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,

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.
