Firefox Support Forum

Hey, I've noticed lack of sync in audio when pausing video. What I mean:

Assumptions: - Using bluetooth headphones (tested only on airpods pro, 2 different pairs) - system MacOS 14.2.1 - Macbook Pro M1 Pro

1. Play any video with audio (vimeo, youtube, custom players) 2. Pause

Outcome: Right headphone audio stops first Left headphone audio stops after small delay

Expected outcome: Right & Left headphone audio stops at the same time

I'm quite sensitive to things like that.. maybe someone knows a fix for this or this is just Firefox bug?

This started recently, after I installed the latest upgrade of Firefox and the video downloader. Not happening on Safari or DuckDuckGo. I suspect they have spotted I am using Firefox and are lying about the connection problem. Any suggestions welcome. thanks!

Macbook Air, Sonoma 14.1.2, second monitor connected via hdmi. This oval purple icon showing a person in front of a screen suddenly appeared in and behind upper left hand corner of window, and is now in all my windows. (see attached image)

What is it? What does it signify? Thanks for your help! Kathleen

I noticed that a couple of times when I click on an external link on a mail or a bookmarked site as icon on my mac, Firefox closes all the tabs and open that link in a new window, so I lose all the tabs and address... Sometime I have more than 30 tabs open and i't difficult to reopen all from history. What happen? Why? I can't see also the "restore last session" command into History menu. Can be fix it? Thank you.

I Use Mac OS Firefox as my primary client for Gmail, and I always compose emails in a pop-out window. Ever since Firefox 124, these pop-out windows include the tool bar and bookmarks bar, eating up a bunch of space. I do want those bars displayed on my main firefox window, I don't want them displayed on the pop-up Gmail compose windows. Is there anyway to get Firefox revert back to this old behavior?

on most current macbook, when opening downloaded PDF, it does not open in my selected PDF preference. i have it set for my preferred PDF reader, yet it opens with a completely different one. i have checked all settings i can think of bot on the mac and in firefox, and am flummoxed. all i am finding are windows articles with help, and i checked those too but still nadda. anyone else have any suggestions?

I have the Dark Reader extension, because white screens HURT MY EYES. This is an accessibility issue! ALL of your support pages do not recognize or respond to the dark reader extension, and leave the page backgrounds WHITE! I can barely stand to write this! UGH! Thank you for fixing this!

Since yesterday, occassionally while using Facebook or Messenger, the tab crashes. Earlier today on the Messenger side, after reopening the Messenger tab after it crashes, it crashed again. It doesn't occur on other websites and the app doesn't crash, only the tab.

Using Firefox on "troubleshoot mode" doesn't have an issue when accessing when I visit those for a few minutes and with only one or two tabs open, and I'm afraid of visiting these sites for a while because it may crash again. Occurs on both Windows and Mac.

Crashed signature leads to: "js::gc::AllocSite::incTenuredCount", and I have no idea what does it mean. For my Mac the reason for the crash is "EXC_BAD_ACCESS / KERN_PROTECTION_FAILURE", while for Windows, reason is "EXCEPTION_ACCESS_VIOLATION_READ".

Heres from my Mac: bp-b882a473-a8a5-496f-8a14-d9d190240403

I will add additional crash IDs from my Windows. Idk what is the problem currently, is it with the add-ons installed, Facebook, or Firefox itself? The RAM is fine.

Currently, there appears to be only one option to tell Firefox to open a given site in a specific container; that is, from the URL bar, to the right.

Would it make sense to have this configuration option presented in "edit bookmark" and/or in a right-click pulldown menu "Always open in this container"?

Hello,

I use Firefox stable on both my Mac and my Win 11 PC. On the mac i use the developer edition. The issue I have started about 2-3 weeks ago. Most of the time, playing youtube 4k videos just either freezes and doesn't buffer, or just skips and reloads. It is not a network issue. I've tried playing back the same video with ARC on OSX (which is based on chromium) and with Chome on windows. It works flawlessly so it's not a network issue. I've tried disabling adblocker, all the extensions, nothing. It's either Youtube messing with non google products again or a problem with Firefox itself. I even have Youtube premium and this stuff still happens without adblockers.

Any help would be appreciated.

I use OnlyKey usb key as FIDO2 MFA with most of my accounts. On Firefox 123.0 on MacOS Sonoma 14.2.1 (23C71) however, I get presented with multiple pop ups to touch my usb key but the key expects only one input/touch and it fails when I touch it the second time. This was not the workflow that I used to use before and it still works fine on MacOS ventura with Firefox + protonmail.

When I scroll through Facebook, often if there are two posts with photos, the browser seems to jump back and forth between the two images making it impossible to see or read either. My release is 123.0 and it was loaded when I needed to restore my system after a drive upgrade about 10 days ago.

I can't print an email. The whole screen prints and is too small to read.

I read previous answers to use the drop down menu and select print, but then I get window that says I have a blocking the print. I don't have an active blocker. I do have malwarebytes. Never had any trouble printing on chrome or safari.

On my Macbook air (m1 2020 14.3.1 (23D60)) /etc/hosts is ignored by Firefox 123

i've tried multiple offered (old) solutions from stack but non work.

FAILED ATTEMPTS:

• DNS over https -> off
• network.trr.excluded-domains ... tried to add the domains in the dns over https exeptions ... didn't work either
• added the domains to network.trr.excluded-domains
• cleared cache
• restart ff
• migrating all my /etc/hosts config from multiple domains on a single line to separate lines did. Hope this helps someone.
• network.ttr.mode = 5
• sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder in the terminal

Background: I run my own server and I cannot access them over the internet if I am on the same network (rounter dissallows this) This is annoying as I cannot develop via my laptop.

/etc/hosts is changed and in the terminal all (ssh etc...) works fine.

What is the proper way of doing this these days?

Hi, I like to know how to transfer addresses to bookmark toolbars? I have the copy all addresses of bookmarks in the previous firefox. I transferred all, but they are in one bookmark, not in toolbars, or other bookmarks. I like to set the same as the previous bookmarks. Thank you so much for your help, Miyabi

Every time I quit FF, FF crashes, or my Mac crashes, my bookmarks either disappear entirely, or the toolbar bookmarks and/or my "Other Bookmarks" folder disappear while leaving my main "Bookmarks Menu" bookmarks. When I tried to restore from json backups, I discovered that my last one seems to be from last October. So I used Time Machine to restore my FF user profile from March 1. This works, but then I go through the cycle I just described above again ... and again. New backups of my Mac do not hold onto the bookmarks when I restore FF user profiles made after March 1.

When I try to manually back up my bookmarks or export my bookmarks to an HTML file from inside the "Manage Bookmarks" window, everything seems to work, but then when I go looking for the file I supposedly created (e.g. bookmarks-2024-03-04.json), no such file exists in the location where I saved it and searching for a file with "bookmarks" in its name yields only bookmarks from other browsers and the old bookmark backups from last October and earlier.

Hi all.

My sync is only sometimes working. I notice that when saving a bookmark and trying to find it on another device. I sometimes have to manually resync it or wait for a few days to get it shown on my other devices. Same with the tab sharing across devices.. In most cases it doesn't work at all..

Here is a current sync-log: https://pastebin.com/TWugtAbm
