Firefox Support Forum

Catalina (10.15.3) and Firefox (73.0.1) aren't working together. As soon as I stop actively using Firefox it crashes. If I try to reopen it, I get a message that I can't reopen it because there is a copy in use already. If I try to force quit Firefox it is not in the force quit menu. If I look in Activity Monitor Firefox is not present there either. Thank you.

When opening a link from a different application, like slack, the keyboard shortcuts like new tab and refresh do not do anything, and the left click menu is empty except for the snapshot button.

This only seems to happen if firefox is not already open and the clicking of the link opens firefox.

I have downloaded the "latest version" of Firefox to my Mac which is running macOS Catalina Version 10.15.3. After 7-10 days Firefox will not "open". I then uninstall it, and reinstall it. Again it works for 7-10 days then will not open at all. I have gone through these install / uninstall processes at least 10 times. Yet after 7-10 days Firefox will not open. What is causing this, and how can I keep Firefox working continuously on my Mac? Thank You. WA

P.S. - I am sending this question from a Windows 10 computer because I cannot open Firefox on my Mac.

As the question says. I updated my Mac (2018 MacBook Pro) to the most recent OS (Catalina), I've uninstalled and reinstalled Firefox like 6 times, cleared my trash and any and all Firefox files, and deleted all profiles, made a new default one, and then deleted that one when it still wouldn't start, and restarted my laptop more than once. I cannot seem to get it to start no matter what I do! I've tried every fix I can find online. Every time I try to launch Firefox, it appears in the dash for a second and immediately shuts down. Trying to start in Safe Mode doesn't work either. Firefox used to work, but then I force quit it *once* because I was quitting all applications I wasn't using. Now it won't work at all no matter what I do. How do I fix this?

Honestly, idk how this started. None of my extensions are new. I didn't install any Apple updates (I'm on a Mac, data posted below).

I tried rebooting in safe mode, which worked. But now it's happening every other time I a window, and the only fix is to quit and restart.

Here's a screenshot so you can see more easily. https://www.dropbox.com/s/10xv6t0wvwo7z3j/Screenshot%202020-03-29%2009.56.11.png?dl=0 (also uploaded below)

As you can see, the open/minimize/close buttons are gone, and I can't click any of the extensions, type, open the Help sidebar, etc.

In Firefox Gmail, trying to use Google Hangouts to call and the microphone is not available. I've added a picture of how it looks in Safari and Chrome with the same Gmail account. Yet in Firefox the microphone option is not available (see pic).

I've tested all the mac functions and the Built-in Microphone works in for dictation, FaceTime, Skype, etc. It Also works well in Safari and Chrome, just not in Firefox.

Anyone has a solution?

Today I update MacOS Catalina and the same as the update some weeks ago Firefox is removed. I could not find the app anymore (the dock presented a big ? at the place where firefox was.) Last time I downloaded and re-installed Firefox, but today again all is gone after the automatic update of Catalina. On my iPad and iPhone there are no problems. Now I did remove all remaining Mozilla files on the Mac and are prepared to download again.

Why is the app removed? Or must I adjust the installation

My Firefox crashes frequently with iOS 10.15.5, the newest iOS. This happens especially after a period of rest when I am not using my mac. Performing a Force Quit often helps, for a while, but sometime I have to reboot because Firefox is not responding. In fact, a regular Restart sometimes doesn't even work, and I have to press the off/on button. Yesterday I deleted Firefox and reinstalled it. No change in problem.

Is anyone else experiencing these problems.

Since downloading the latest version, the browser stops functioning after the first site. It won't even allow me to quit, without the 'force quit'. Plus, while in the first site (my local newspaper) it stops recognising key strokes and mouse clicks. In fact, everything stops working.

I'm sending this through Chrome.

Any fixes?

Thanks, Stan Nikolic

Hi, my firefox started to crash regularly for a few months. I have seen it crash while on idle, while changing tabs, while opening ne tabs... i.e. no repetable pattern. Morever, I couldn't figure out the reason since all the crash reports turned different reasons for each crush. It has now become hourly crashes which really started to affect my workflow. Could you please help?

I received an error message warning of suspected malware when attempting to update a Firefox password using Dashlane and chose the block option. Now whenever I try to open Firefox I get this message:

The application “Firefox” can’t be opened.

I have tried reinstalling Firefox but it doesn't work. I do not know which app sent the original message, since I did not have Norton app blocking activated.

A group of experienced hackers have made my devices their target. They continue to remove any security I try to place on my computer, i.e., downloading developer apps which allow them to administer the computer and devices.

They have maliciously targeted my business and sabotaged a lot of my apps so that they will not work. Going to the "Authorities" is a waste of time. so I will not discuss this.

I need help in tracing the street trash thugs who continue to access my computer, place malicious malware and worms on my computer so that it will not function at his required level, and replacing bonafide adds with fake apps so that they can control and conduct surveillance on all of my Apple Devices.

I have reported this problem to Apple and they are worthless. Not enough training, and the service is inferior.

I need upper level technical support to identify how they are manipulating my browsers so that they provide absolutely no security.

Malwarebytes is manipulated, Avast as well, and they have downloaded an app that allow them to share my screen and collect all of my passwords as they are individually entered.

Hello,

Thank you in advance for your assistance.

FF v79 crashes multiple times per day, always when I click on a button, link, or anything. rolling back to v77 did not help. FF Nightly does it too. can't find a fix!

MacOS Catalina.

Hi, I've been experiencing quite a concerning bug (I hope) in which the Firefox Download Button Animation starts by it's self at random intervals with no warning whatsoever and no downloaded file in /Downloads.

Its been happening for a bout 2-3 weeks now I think and is beginning to worry me.

Thanks

When I receive an email with an inline/embedded image, I only see the image's filename. When I insert an inline/embedded image into an email, I see the image, but once it is sent, only the image's filename is displayed within my email--the recipient is able to view the image as normal on their end. This image issue has not affected image searches or anything other than in Gmail using Firefox--I can see the images when using Google Chrome and Safari. Any advice or help is greatly appreciated!
