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.

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 have a 2012 MacBook Pro, still using maverick's … I tried to upgrade Mozilla and now it doesn’t work.

I am shy of what’s needed to run the latest Firefox version and I’m not able to buy a newer laptop, how can I get restated again with the version that will still work on my MacBook ?.

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.

Hello,

My computer does not support the latest firefox software update so i was wondering if you can send me me the firefox 115.0 version firefox softare? I tried to search for it online but i wasn't able to find any because the software i have for firefox now won't let me open some pages on websites because i have a old version firefox software. So please send me the 115.0 version software so that i can download and update my firefox software. Thank you

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.

Hi My version of Firefox will not be supported after Jan 14th - I can't download an updated version of Firefox because my Mac is IOS 10.10 and apparently it needs to be at least IOS 12. What can I do? I will be updating my computer but I don't want to lose access to my docs etc on the 14th Jan. Thank you - I would appreciate help please.

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.

I want to know whether I can update my current Firefox version with my very old desktop setup. I am using the Firefox browser version 78.15.0esr (64-bit) on my iMac 2007 running OS X El Capitan. This notice came up when opening Firefox: " Your version of Firefox will start to have problems on January 14. A root certificate will expire, causing some preferences and other features to stop working. On March 14, 2025, add-ons and more features will also break." Following the instructions to update, in About Firefox window, it checks for updates and then shows Firefox is up to date. I've interpreted this as there's no version available that I can update to. Is that correct?

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?

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.
