Firefox Support Forum

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.

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?

Firefox 123.0 MacOS 13.6.3 Ventura

Firefox does not automatically create a new empty window on startup. Neither starting from "applications" nor clicking icon in the dock

Instead once has to right click the icon then click "New Window"

Why is it that the people who "improve" products are always dickering with the look and feel to no benefit to the user? Why suddenly does a new empty window not open? Fantastic job Mozilla. It takes me an hour or so to figure out how to even get a window with the default web page URL and then I have to perform forever after three clicks instead on one.

I have a suggestion. The next time you think about changing the look and feel: DON'T. It is just that simple. DON'T.

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.

Should I use DuckDuckGo Privacy Essentials with Mozilla/Firefox? Would all of the Firefox features work the same or would DuckDuckgo replace Firefox features? If both worked together it would seem to be the best option. I would greatly appreciate some input on this.

M2 MacBook Air running macOS Ventura. When I open a website which wants access to my camera I am asked if I want to allow this. I say "Allow", and the light next to the builtin webcam turns green, but I see nothing in the camera sub-window on the webpage which was granted access. No error message, just no camera video is shown by the webpage. In the menu bar is a camera icon which I can click on and confirms I have "Allowed" camera access. Setting / Privacy / Permissions / Autoplay is set to Block Audio. I have verified the camera works with other apps (Photo Booth). How can I diagnose this?

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!

Everyone says my audio sounds distorted in google video chat. I had been using it for months without issue on Firefox, and then I got a new Apple computer and people started to tell me I had this issue. In order to isolate the issue I tried going on Teams Video chat and Zoom video chat and people said my audio sounded fine there. Then I opened Google Video Chat in Google Chrome and people said my audio sounded fine there too. Lately, it's only when I'm on Firefox trying to use Google Video Chat (aka Google Meet) to video chat and people say my audio sounds way too distorted to hear what I'm saying. I restarted my computer, I even checked for the latest browser, which is up to date, I can't figure out how to fix this. Sounds like a firefox issue. Any ideas?

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 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.

how do i make my firefox multi account container thing open links from external applications in the container of my choosing, rather than auto opening in no container?

Apparently, for some time now the updates versions of Firefox (currently 124.02) has many incompatibilities with macOS Sonoma 14.4.1. Thinking I could fix it, I re-installed Firefox and currently I no longer have access to any of my favorite sites and mailboxes, all my pass-words are refused.
