Google and Bing miss the first character of my search. When pressing search the results do not show any detail or urls. Firefox is up to date. Mac OS Catalina 10.15.7. See Screenshots 3 and 4. They work correctly on other browsers. I suspect there's something in Settings, but I can't find it myself. Help! See Screenshots 1 and 2.

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.

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 cannot select 8K60fps Youtube playback on my M4 Mac mini, so please add support for this in the Firefox MacOS browser for Apple Silicon devices, or at least the latest M4 series of chips.

A graphic displays on my M3 macbook pro running Sequoia whenever I open Firefox. I've searched online and have read posts that suggest it may be a malicious bug of some sort. The graphic which I am attaching , isn't captured when I do a screenshot, and disappears in about 15 seconds. I took a photo of my screen with my phone in order to capture it.

The graphic/alert states that "the latest OS version is ready..." but the OS is up to date. Nothing happens if you click on the "Details" button.

Anyone else having this problem?

Thanks

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?

After accidentally closing firefox I could not restore my last session after going to. history because the restotre tab was not there. Only recently closed tabs and recently closed windows and search history was there. I also had the box sent in setting to restore last session but it did not do that either. Am I missing something. Sorting through all the history would take quite a bit of time. I am on a macbook with sequoia ios.

Thanks

Hi! im getting difficulties to user the browser and the websites im trying to browse ask me to update my firefox browser .. when i check for updates it says: im up to date and cant update more.

im a mac user with 10.9.5 software system

Background: I need to run an enterprise web app on selected PCs and Macs, the browser will not be used for browsing, do not highlight security risks.

I must absolutely use Firefox 48 because it is the latest version to support showModalDialog()

I installed Firefox 48 on Windows and everything is ok, it works as it should.

On MacOS Sequoia, on the other hand, Firefox starts, the menus in the “Apple” bar at the top are usable, but the browser window is totally transparent, only the border and title bar are slightly visible.

I read on the support forum that it might be enough to disable hardware acceleration, but I can't do that because the options page doesn't even show!

I'm running Firefox browser 88.0 (64) bit, and have been trying since before Xmas to upgrade it to a newer version. It's installed on an older Dell laptop running Ubuntu 16.04 LTS (which I've also tried repeatedly to upgrade without success).

I've tried to upgrade both through the UI, but also tried using the command line in Terminal. Per advice in other threads, I've found the best mirror site and changed my settings to use that, but still no luck. Even the preliminary "sudo apt update" via Terminal fails; the first error tells me that the public key is not available. I assume that's the place to start, but don't know how to correct it.

I'm up against the deadline for updating my browser, and would very much appreciate any help you can provide. (Please note that I'm posting from a newer computer, so automatically generated info about my system won't apply. See the screenshots for that info).

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?

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.

In some pages, redaer view shows the wrong text -- it looks like it picks up text from a hyperlink. An example is this page:

I am using Firefox 134.0 on MacOS (Sequoia 15.2)

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 !!

I have a user at my job that installed the latest Firefox update (13324.11.21) through our MDM. After installing this update she cannot launch Firefox. When attempting to launch she receives a request for a username and password to install a Helper Tool. She is an admin on her machine and enters her credentials. The message closes and nothing happens. When attempting to launch again the same thing happens. This is not happening with our other 100 Macs who have the same Firefox version and others who have the same OS.

Is anyone able to tell me why this is happening or how to fix? Any assistance is very much appreciated.

The below troubleshooting steps have been done:

Uninstalled and reinstalled Firefox

Updated the OS to 15.0.1

Disabled the Master Password on Firefox through a Mac Profile

Checked if there was a Firefox file under /Library/PrivlegedHelperTools

Granted Full Disk Access to Firefox under System Settings

I'm tired of trying to find a solution to this problem, you're deaf!

I have been using Firefox since 2003. to avoid writing unnecessary words, I will simply state, I will leave firefox if you do not eliminate this problem:

firefox eats up all the RAM on my Mac. It is none of your business whether I open 1 tab or 10 tabs, give me the ability to limit the memory used by firefox, otherwise it eats up all the computer's memory.

I downloaded the latest version of Firefox. The directions tell me to open the file that i just downloaded, which is fine, except that I don't know the file name or location. What is it, and where is it? or how do I f find out?

Can MacOS High Sierra play Netflix? I cannot update to the most recent Firefox because my 2012 iMac cannot update to Catalina. Netflix says I need a new version of Firefox. How can I use Netflix on my iMac?
