Safe Mode and reinstalling does not work, tried other version and Nightly, it crashes before even starting the browser. I don't know if it's related, but I used the Windows Check Disk function before this.

Crash ID: bp-fc921be9-068e-4555-9cb4-c08000200927

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.

Here are some ID about my crashes

Again asking for help to turn off the popup urlbar "pic related",I have asked the same question back then in Nightly version 75.0a1 when this (irritating) feature was introduced and I tried the same steps but setting "browser.urlbar.update1" to "false" doesn't work.

is this permanent? if so why? if I wanted a bulky UI I would just use the Touch Mode or the Normal Mode, at least give us the option to turn it off/on, my problem with this is 1- it ruins the Perfect aesthetic of the UI and make FF looks like Quasimodo (just saying FF has the best UI out there) 2- it overlaps with other elements of the Compact UI like the bookmarks toolbar making it irritating as a "Jack Russell terrier"

and do me please a favor Don't ruin the compact UI

As indicated in the question. At some point (FF 69) I had to turn from Tab Mix Plus to a patch from off the web which worked for several versions. Now that's broken (may have something to do with chrome/userChrome.css loading - but that's just a semi-informed speculation).

Found this

https://github.com/Izheil/Quantum-Nox-Firefox-Dark-Full-Theme/tree/master/Multirow%20and%20other%20functions

I believe I've set it up correctly (correct files in the correct locations) but so far it's not working. It seems the github site doesn't take bugs/questions so I'm trying to remember how to debug these files where the first question in this case would be: am I even loading what I think should be loading? There's a JS loader patch to be put (in my case) under c:\program files\Firefox Developer Edition - and then the files for multirow in one's profile directory chrome subdirectory. Roaming (users/xyz/appdata) as opposed to Local - however did notice that one should clear out one's startupCache directory (under Local). Which I did.

Hi to all!

I'm on Firefox Nightly 71.0a1 (2019-09-20) (64-bit) on Arch Linux. I'd like to watch a mov video, embedded in a website. The video is fine but the control shows it as muted. Indeed there's no sound. If I click on the sound control of the embedded video player, I can't toggle the sound control, which stays muted. The controls works on Chromium so it's not a problem of a video with no sound.

Thanks a lot for your help!

EDIT: I've tried with other mov files. I went to the Apple site: https://trailers.apple.com/trailers/focus_features/downton-abbey/ I can watch the clip with sound but here the audio control can't be toggle or change: the volume stays at the same level.

Min and max buttons are not available on extensions windows, beside that those windows are always on top (only of Firefox itself, not in other windows), so I can not continue using Firefox when one window is open. My specific case is that I need to use "Katalon recorder" extension, but i can't, since I need to move the windows around to record my moves on any page, which makes it really annoying. Is there any workaround for this?? (I am on linux deepin 15.11 and Firefox nightly 71.0a1 (2019-09-09))

On Debian Stretch, Firefox Nightly 68.0a1 (2019-04-03). For the past few days Firefox won't load any pages (after the initial load), everything freezes essentially.

A tab may start to load (loads the window name into the tab) but then switches to a white screen with a loading indicator in the middle of the screen. Generally this freezes the interface as well, so I can't right click or close the tab.

Usually I just wait for an update, but I've updated Nightly 3-4 times since this started happening so I'm getting a little annoyed as I'm having to use Chrome.

I've tried restarting with addons disabled, tried the nightly 'refresh', nothing works sadly.

It has crashed about.... way too many times in the past 3 days, here's a list of my crash reports:

There's a new feature on Nightly that lets multiple profiles run at the same time. However, since i run my Firefox on a manually-defined (with -profile) profile, any links opened from outside Firefox open in a new window, with the blank default profile. Is there a way to override this?

In many pages, always show me this message: "Wow! Your tab just failed." What should I do?

This is a lot of codes-problems of Firefox.

Hi I keep getting this message "You’ve just been upgraded to Firefox Nightly 67!" every time I open Firefox. I checked my homepage setting and that is set to go to Google.

This message is driving me nuts. I've even tried to block it with add blocker to no avail.

Happy to provide further info re add on's etc. I am running Windows 10 64 bit fully current.

So, every now and than in last week or two when I try to open Nightly i get like 20-30 windows of "Firefox Nightly has stopped working" error, like shown in the image. It continues to multiple until that message in the center opens and then i have to manually close all opened error windows.

Sometimes it works fine, sometimes this happens all the time. Anyone got a clue?

Hi, Dear Firefox Support team. I'm currently using Firefox Nightly version 65.0a1. In the settings I selected enable DNS based on HTTPS and the address is default: https://mozilla.cloudflare-dns.com/dns-query And I can access to this cloudflare-dns website. but when I use wireshark, and browse Internet, I still find I'm doing DNS query each website, why is this happen? Doesn't the Firefox Nightly suppose to tunnel these traffic into https?

For about one month ago, YouTube HD videos (720p, 1080p) are not playing smooth on Nightly, regularly updated. Is there any solution? My machine is powered by Intel Core i5-4570, no graphic card. Thank you

I have website which i occasionally visit and it prompts username and password every day (since sessions are configured that way) and Firefox (latest 62.0.3, freshly downloaded) nor Firefox Nightly. I've tried everything, disable acceleration, add-ons and everything i've found on your blogs. Website does allow to autocomplete. Every other browser save username-password combination.

Fields have props: `autocomplete="username"` and `autocomplete="current-password"`

1. I use user styles in Stylus for safety and accessibility and readability tools on Firefox. I also use user css for some of the most important tools.

2. I tested a bug in Firefox Nightly. I then returned to Firefox.

3. I lost all my safety and accessibility and readability tools which used Stylus.

Is there any way to get them back? I use MacOS, so Time Machine might include the relevant files.
