Multiple firefox icons in mac os x dock after upgrade to 112

okfine — Tue, 11 Apr 2023 18:52:48 GMT

After upgrading Firefox from version 111.0 > 112.0 every time I quit Firefox another icon now shows up in the dock? If Firefox is closed x3 then 3 Firefox icons show up now (Ventura 13.3.1) Any help would be appreciated.

Same here, except I don't get a new icon, my dock starts to move like its going to create one then bounces back, tried a profile restore and downloading Firefox again, no idea what's going on. Had to be a bug with Firefox or maybe Mac OS Ventura, mines on a intel iMac circa 2017 BTO

You can reset your Firefox by removing two files, but remember to backup your bookmarks, before you do that - it worked for me.
The files I have removed was installs.ini and profiles.ini - maybe you only need to remove one of them.
The location of the files:
/Users/your_user_name/Library/Application Support/Firefox

Actually, I’ve noticed something if you unable Firefox to clear cookies and history it does not create multiple icons it but if you turn that on it does. I have Firefox generally set to to delete cookies and site data but now if I have that ticked it also for some reason automatically ticks the box to clear history too, when Firefox closes which is new behaviour, it didn’t do in version 111, so if I have those ticked because you can’t have one without the other for some reason, when you close Firefox 112 it does that weird adding an extra icon thing. It’s really annoying. If I untick delete cookies and site data and now delete history after resetting my profile it not does try to add another icon in the dock, so the only way round this is for myself is to have Firefox not set to delete history ticked, this got turned on with 112 since I have cookies and data set to delete and as mentioned turn one on and the other now gets turned on then it doesn’t do that bounce and reproduce new icons, it does not remove the cookie data when shutting Firefox down any more as delete history and Cookies and data on shutdown are now linked for some reason.
Add ons I have are Ublock Origin and Firefox's Facebook Container. Try resetting your profiles to see if it stops this unwanted behaviour, or delete history when Firefox closes to see if that stops it as it has for me until this gets patched.

In Monterey 12.6.5 the same thing happens. When I close Firefox my dock starts moving as if to create a new icon.
When you try to open Firefox again, it doesn't open and you have to wait before you can open it again.

What a botched new version!! 🙁

Charley — Thu, 13 Apr 2023 09:50:41 GMT

Killhippie, you are quite right, if I tick "Delete cookies..." the odd behavior with the extra icons is back - my test wasn't good enough. I have also tried a complete new install, after renaming "/Users/my_user_name/Library/Application Support/Firefox", without any difference in behavior.

Re: Multiple firefox icons in mac os x dock after upgrade to 112

Killhippie — Thu, 13 Apr 2023 11:31:57 GMT

Has Mozilla been made aware of this mess? I notice they had lots of new team help on board and volunteers, I'm not saying that the issue is their fault but its funny how this is one of the buggiest releases since they have told us that about the new team members and volunteers!

These issue needs to be fixed quickly, as does not being able to just have delete cookies and site data on without clear history when Firefox closes being turned on as well by ticking delete cookies and site data, which was never how the browser worked before. I just like to clear cookies and site data but not clear Firefox history, that worked fine in 111, this is a right mess and one of those settings causes this extra icon mess to trigger.

Re: Multiple firefox icons in mac os x dock after upgrade to 112

Charley — Thu, 13 Apr 2023 12:59:55 GMT

Yes, quite annoying. Another workaround could be to disable "Show recent applications in dock", but of course this is not so convenient. Go to System Settings > Desktop & Dock > Dock > Show recent applications in dock.

Thanks for the heads up, but it’s not the handoff feature as I have handoff turned off on my Mac. This seems to be affecting Intel Macs so far from what I can tell. If you could pass this on to whoever needs to have the information because this is becoming really frustrating and I’m surprised Mozilla hasn’t heard more about it yet. Thanks again for your help.

Re: Multiple firefox icons in mac os x dock after upgrade to 112

Great to know if one person maybe files a detailed report and links to this page that will get the wheels moving. Multiple reports might not help. I’m sure. I remember seeing in reports before if it’s the same bug reported over and over again, it doesn’t really help matters.

Re: Multiple firefox icons in mac os x dock after upgrade to 112

I have been dealing with this issue all day and have gotten used to it. Every time I close Firefox, I get a duplicate icon in my dock. But here is something odd, just minutes ago, I had both Firefox open and Spotify open on my desktop. I closed Firefox first and for some odd reason, no duplicate icon appeared in my dock. First time this has happened.

Re: Multiple firefox icons in mac os x dock after upgrade to 112

edmechem — Fri, 14 Apr 2023 20:09:29 GMT

I'm also on Big Sur - my issue is a bit more weird. When I quit Firefox 112.0, the Dock starts moving strangely, as if new items in the 'minimized' portion were trying to appear, then failing, and repeating. But then eventually Firefox crashes. Just briefly mentioning this here, I'll look around & see if anyone has yet submitted a bug report similar to this behavior I'm seeing (crashing after trying to quit).

Someone else needs to make a bug report with more detail about the fact that it’s triggered when you use delete cookies and data or delete history, and the fact that you can’t separate those two anymore, either when you click delete history, it now ticks delete, cookies and data and vice versa, where as before they were separate if you turn those off, it doesn’t do the extra icon thing, if someone could post that that would be great and also a link to this forum, where all the posts are would help Mozilla to see that there are many people having this issue.

Re: Multiple firefox icons in mac os x dock after upgrade to 112

spicy83 — Sun, 16 Apr 2023 15:40:55 GMT

I just tested it both ways, with deleting cookies and without deleting cookies and both results ended with the same result: extra Firefox icon on the dock.

Re: Multiple firefox icons in mac os x dock after upgrade to 112

Killhippie — Mon, 17 Apr 2023 10:39:20 GMT

really odd as on the latest version of macOS Ventura 13.3.1 changing those switches stops it and it does not crash either. In fact no extra icon appears but the dock moves as if one is about to. I think they are now aware of the issue looking at Bugzilla.

ScottO — Tue, 18 Apr 2023 20:00:06 GMT

I had the same annoying problem with 112 on Monterey, and again after upgrading to Ventura 13.3.1 today. I quit FF and they appeared (all 3) I then went into the System Settings (System Preferences) > Desktop and Dock and turned OFF 'Show recent applications in Dock' - Restarted FF then quit it and the 3 icons did NOT appear. Then went back and turned ON 'Show recent applications in Dock', started FF and after browsing a page or two, quit FF. The icons do not appear now, yet other new 'recently opened' app icons do still appear. Give it a try, weird fix but it worked for me!

Hey all,

Quick update...

This should be fixed as of now in the release channel. Thanks again for your patience as our team worked on a solution.

Re: Multiple firefox icons in mac os x dock after upgrade to 112

Killhippie — Thu, 20 Apr 2023 12:31:24 GMT

So does that mean we have to stay with this problem for five weeks or so on the stable channel until you release version 113 because that’s pretty unacceptable to be honest and I’m not downloading beta software.

Killhippie — Sun, 23 Apr 2023 16:58:46 GMT

That just puts you at risk because of browser security it means you just have to not delete cookies when the browser shuts. Is it better to do that until the next than put yourself at risk of getting malware or worse because your browser isn’t up to date and protecting you?

Re: Multiple firefox icons in mac os x dock after upgrade to 112

Hadrian — Wed, 24 May 2023 12:35:01 GMT

I am now using Firefox v.113 with MacOS 10.15 Catalina, but the problem is still present. The correct operation is obviously to show an icon in the recents section of the dock only if the app is not already permanently displayed in the dock. I wish to delete cookies etc after each session, so this multiple icon glitch makes Firefox look a little half-baked.

Re: Multiple firefox icons in mac os x dock after upgrade to 112

Hadrian — Wed, 24 May 2023 20:33:51 GMT

I have been a fan of Firefox for years, I prefer it to Safari on my Mac, but when such an obvious bug slipped through the testing stage I started to wonder what else might be going wrong out of sight. When I was a programmer I learnt certain points on which programmers often fall down – e.g. limiting conditions, system initialisation (relevant to this case) and rigorous testing. Yes, in v.113 the bug appears to have been fixed, but the question remains: how was a version of Firefox with a glaringly visible bug ever released?

Re: Multiple firefox icons in mac os x dock after upgrade to 112

Killhippie — Wed, 24 May 2023 21:10:28 GMT

Firefox is working fine on my Mac it’s been fine on 113 with the delete cookie data setting turned on which also turns on the delete history setting which it never used to but it does now. I think you might need to create a new profile and then just put your add ons back on. I think since Firefox 112.02 I haven’t had any problems and no multiple icons and it’s still fine on Ventura 13.4 and was fine on the venture 13.3 as well.

Re: Multiple firefox icons in mac os x dock after upgrade to 112

Hadrian — Thu, 25 May 2023 12:44:24 GMT

Killhippie, you are right, when I first downloaded and opened v.113 I should have realised that the Firefox icons in the recents dock were garbage from the previous version which I had to remove manually. They should have been cleared by the browser when it opened – system initialisation!

Re: Multiple firefox icons in mac os x dock after upgrade to 112

rogger13 — Mon, 16 Jun 2025 18:20:04 GMT

That definitely sounds like an annoying issue. It's likely related to a bug with how Firefox is interacting with macOS Ventura's dock management. You might want to try resetting the dock using Terminal with the command: killall Dock — it can sometimes clear out stuck icons or weird behavior. Also, make sure no leftover instances of Firefox are running in the background when you quit.

If you're looking for lightweight alternatives for testing on different platforms, I've been checking out some apps via android recently — handy if you're exploring cross-platform behaviors too.

Hope that helps!
