I have Canon EOS Utility installed in order to use a better camera when streaming. For some reason, when I'm using Google Meets, it will only let me use EOS Utility, ignoring the option of using my laptop's webcam. I've tried revoking permission, but when it asks me for permission again it won't show me my laptop's camera, only EOS Uitlity. I've tried disabling EOS Utility under Windows settings, but it's still the only camera that appears.

I'm having this insanely irritating bug where when I have my DAW software, specifically FL Studio, open at the same time as Firefox, and I try to pull up any sort of video or content, whether that be Youtube, Twitch, Dropbox or Google Drive files, or even videos just being queued up by Twitter or Reddit in the background, there'll be a chance that Firefox sort of "crashes," and goes all white (or grey with the default theme) for up to dozens of seconds, and forces the video to reload, or it just breaks the player.

​I need to be able to use my browser and my DAW at the same time to preview and drag files into it, and to work with video, so closing one or the other isn't an option. I've tried everything short of a drive wipe and OS reinstall; I've tried making a new profile, disabling extensions, disabling hardware acceleration, the troubleshoot mode, and even a complete wipe and reinstall of both Firefox and FL Studio. Nothing has worked.

​Has anyone else had that issue and hopefully been able to fix it? Or does anyone know any way to alleviate this? Thank you!

​I'm using Windows 11 Pro on a Framework 13 with an AMD 7840U with all the latest updates and drivers, and can provide specifics if needed.

It is sort in the background like a page behind the main screen I am viewing but it causes Firefox to crash. I have seen other posts say disable hardware acceleration, but mine is disabled, others say disabled extension, but I only have ublock! It is not my graphics card as it is all up to date.

Local File Access

Dear Support Team,

I tried enabling localfilelinks in firefox and found this thread https://support.mozilla.org/fr/questions/1264779 which mentions creating a "user.js" file and adding this:

/ Create policy enabling http: or https: pages to link to file: user_pref("capability.policy.policynames", "filelinks"); user_pref("capability.policy.filelinks.checkloaduri.enabled", "allAccess");

// Sites to which the policy applies (protocol://hostname protocol://hostname) user_pref("capability.policy.filelinks.sites", "http://example.com http://intranet");

then reloading firefox.

The fix worked and i was able to use local files in firefox. My Problem now is reverting localfileaccess to default (blocked).

i tried modifying the "user.js", deleting it, deleting and reinstalling firefox, cleaning the firefox install and creating a new profile. when i deleted user.js the enabled options vanished from "prefs.js" but local file access was still enabled. I also tried to edit the generated options in about:config but i cannot get it to revert to localfile access beeing locked and couldn't find any way to fix my problem.

Is there an easy way to relock this?

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?

This brings up something I have been trying to fix for more than a year. When I click on the email link "Start with a free scan", google.com appears at the bottom left and nothing happens, not just with your link but with all. I have waited many minutes just to see if it will link. Sometimes, after minutes, it connects. I have been trying to get Google out of this in "mailto" but cannot. If I right click "open in a new page", google does come up, the target site does (I think) and we move along normally.

Can't you fix this? Google it and you'll see it everywhere. Mozilla has a suggested approach online which does not work. Please help all the AVG and Firefox folks who suffer with this.

Thank you,

In the browser settings I use a color preference that replaces white with black, this works with pages where Dark Reader is not available. These settings are needed so that when surfing the web at night with the dark mode on, my eyes don't hurt from contrasting bright white elements with dark-colored pages. For example, it works on single image pages - in situations where except for the image the rest of the page is colored solid white; It also works for some add-ons - on settings pages and pop-ups.

I'm interested in being able to automate toggling on/off the «Use system colors» checkbox, which is in the browser «Color» settings. It would be great to somehow synchronize the activation of night mode in Dark Reader with disabling checkbox responsible for using system colors. Or, for example, make it so that when the «Website appearance» setting is set to «Automatic», the checkbox is switched accordingly together with it - being disabled when the appearance is dark and enabled when it is light.

I deleted Firefox from my Windows 11 computer because it was having issues. I reinstalled but I did not get back the same settings I have on my laptop. I have tried to do a complete uninstall and remove all Firefox files but, there are files attached to my Avast antivirus that I can't delete. Also when I down load it wont Sync. Firefox is my browser of preference and I do not want to use another browser. I should also note that Firefox has been completely removed from program files, program files(x86) as well as program data but there are still file in Avast and Windows. See picture attached. Help I really love Firefox

I'm using the current Firefox-ESR for Linux x86_64. Under Settings > Privacy and Security > Cookies and Site Data > Manage Exceptions, I blocked http:174.138.51.92 and https:174.138.51.92 several weeks ago. But Manage Data shows 10 cookies last used 45 minutes ago, and Remove Selection for these cookies fails (incidentally retaining the "last used" value), even when repeated multiple times as fast as I can mouse the select, then Remove Selection, then Save Changes then Manage Data .

How can I delete these cookies and site data? And why does it fail for this site and this site only? And how can I block them permanently, short of black-holing that site in /etc/hosts?

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.

Hello, Under about:preferences I went to applications. Under mailto there were references to Yahoo and Gmail which I deleted. Now then when I click on an email address link on a webpage the mailto menu pops up like it always has but Yahoo and Gmail are no longer listed as email options. How do I get those links back? Firefox is listed as the default option but because there are no links to webmail services there is no way to send an email from that menu. Sincerely, MKH
