Firefox Support Forum

I have a 2019 Macbook Pro 16" and whenever I share a FireFox window on facetime, I'm unable to stop sharing it until I end the Facetime call. Even then, the sharing screen notification still appears in the top right in the menu bar and I'm unable to share my screen for future Facetime calls unless I restart my laptop (thus removing the problem). Is this a known issue, and is there a way to fix it other than restarting my laptop?

I have been using Firefox on my Mac for years with no problems. Recently, however, I have been having trouble running YouTube. I get to the correct page for the video I want but the video itself does not show up, just the background for the page. Any idea what I might have done to create this problem?

Just transferred from old MacBook Pro to new one. Successful migration except: The icon for the WE Transfer service doesn't show up in the narrow black ribbon at the top of the Firefox page - instead there's a blue exclamation point in a blue circle. Clicking the blue circle/exclamation point takes me to the WE Transfer page. What do I need to do to get the actual icon to replace the blue circle/exclamation point? Thanks in advance.

So for some reason I have two versions of Firefox on my computer (Windows 64 bit), I am logged in and using one of them, and the other is just there. I could log in there but I don't want to, I just want to get rid of it. Links from Telegram open in it, creating a second Firefox window instead of opening in another tab in the already open Firefox window, which is very inconvenient. The windows list of programs which can be uninstalled only has one Firefox (I've tried deleting and reinstalling, it doesn't help). But when I try to choose a default browser I get 2 icons to choose from which look the same (see screenshot). What the heck? How do I manage this!

Hello,

Firefox currently does not prevent macOS from going to sleep when a download is active.

How do I know this? 1) I downloaded a file from the internet. 1.5 GB in size. 2) I opened a Terminal window in macOS, and ran `pmset -g`. 3) I searched for "sleep" in the "Currently in use:" list, and checked if Firefox was listed. It was not.

Is there a setting that I can enable that I can download to make this happen?

I think extensions don't have the capability to prevent macOS from going to sleep. Correct me if I'm wrong.

A quick fix for now would be the `caffeinate`-command in the Terminal-app, but I think this is very resource-wasteful.

Thank you in advance! Kind regards.

Hi everyone,

I'm running Firefox which I compiled with vaapi support because I was trying to use hardware acceleration for videos, so I think this bug may have something to do with that. Every time I open a pdf file my browser instantly crashes. When I use troubleshoot mode I have no such issue. I then tried with a fresh all-default user profile with no add-ons, nothing, and still I crash when loading a PDF. Any pointers would be appreciated.

Hi there,

I just started using my new MacBook Air, and when I try to use the trackpad to open read Gmail or click the calendar icon on Firefox, it doesn't respond. It works on Safari.

As per the photo, I try to click the calendar icon to open up my calendar and nothing happened.

When switching from one tab to another, streaming stops and video won't play in background. I've tried all the main fixes suggested I've found. Nothing worked. Please help! Will be using alternate browser until fixed as it's too unwieldy for me to use this way.

Hyatt.com can be loaded on other browsers but not on Firefox. There is just a blank page with no error message. There is an archived thread on support.mozilla.or called "hyatt.com". The suggested solutions don't work or are too complicated. So please solve the problem. And STOP archiving threads that are still an unsolved problem! Am using Win8.1 and auto-updating Firefox.

I'm currently on a very old version of Firefox simply because the new versions, each time I try the latest versions, seem to not have the function the old one has. Remembering the websites I put into the address bar. The version I am currently using did have a issue with shuffling the order of the sites based on 'use' but setting Firefox to Private mode kept the websites locked in order and did not make them shuffle if one was clicked more often than another. Is this something I can do on the current version because I tried and looked for a way to do this recently but I kept getting 'autofill' results from google when I just want to be in Private mode, have the websites I frequent be the only ones listed when I click the address bar and not have them shuffle or have any other website I'd type into the bar not add itself to the list. If this is or isn't possible let me know.

There's also no way to add an exception? Just completely broken at the moment. I have to disable OCSP stapling to get it to work at all, which is less then ideal.

Currently using 125.0.3 (64-bit). I checked for newer versions of firefox and it's not saying anything. Chrome and Edge work fine. Encountered this on an android tablet with firefox, and went to desktop and hit the same thing.

Hello, I recently find products added to check out from various sites to purchase. I use all my pcs and other devices. They are all password protected. No one uses my devices. I think some one got my account. I changed the password. Can you help me about this topic Kind regards sami

Why are my bookmarks all of a sudden not working anymore.

Selecting the saved bookmark from DudkDuckGo or Firefox does not load the page.

Did i change a setting accidentally/

Did Mozilla change the functionality?

What's going on?

Thanks for your help.

Note: I can access the page by going directly to its URL ... but what's the point of bookmarks if that is necessary?

Thx. again.
