I type "about:config" and nothing happens. I want to toggle ON the new (?) experimental (?) Do Not Track / Do Not Sell My Info feature. How do I get to Firefox configuration data?

Firefox quit working on my bench window 's 10 computer. I finally had to uninstall Firefox. I then installed a new version of Firefox. Question: did all my saved website locations that I had on original Firefox version get wiped out too? If not, how can I locate them and bring them up again.

When I open a private window, my bookmarks sidebar is showing. I can easily remove it but it shouldn't be there. Until very recently, private windows didn't have the bookmarks sidebar. I don't know why this started but I would like to find some way to have the bookmarks sidebar NOT automatically appear when I open a private window (but of course I want to continue to have bookmarks automatically appear in regular Firefox windows). I've looked online and tried various methods that were supposed to work, but they don't. Can you tell me how I can fix this (minor) problem? Thanks.

Using Windows 10, an Nvidia GTX 1080, and a Panasonic VSX-40 receiver, connected by HDMI.

I recently got a new stereo receiver and have been seeing problems with the HDMI connection. The the image becomes discolored and green at times and stays that way until the receiver is restarted or the input is switched off HDMI and back.

After extensive troubleshooting (replacing cables, updating drivers, testing to reproduce the problem) I have determined that Firefox is the issue.

Playing a youtube video or a twitch stream has a small chance of causing the error. Mousing over a tab with a video in it causes the error almost 100% of the time. The same videos and streams do not cause these problems in Google Chrome.

I have disabled hardware acceleration in Firefox settings and that has solved the issue, but now I have the problem that Firefox is not using hardware acceleration. It scrolls poorly and generally sucks to use this way.

Is there a way to change the way Firefox displays these videos without disabling hardware acceleration completely? Chrome renders them without causing issues, and I've been unable to trigger this error in any way outside of Firefox.

I can login to research.gov on Chrome using biometrics, but Firefox is locked into demanding a passkey I don't have. How can I reset it so it offers the biometrics option?

I tried typing about:config in my Firefox address, searching for security.webauthn.enable_macos_passkeys, then setting the value to false, but that didn't work.

So then I searched for security.webauth.webauthn and set it to false but that didn't work.

been having issues with files lately. i can dl a file and open the folder. if i try to open the file from the browser or the folder directly, the browser window will freeze. additional browser windows are still functional. how do i fix this? no files will open even in safe mode.

When testing our web application, I can consistently get the tab to crash in Firefox (not other browsers). This happens even when running in Troubleshoot mode.

A few of the submitted crashes: bp-f1e47e32-aa7e-4080-880c-34f160250710 bp-622b9363-fa50-4b15-b605-87c3e0250702

Can anyone tell what is causing it to crash, and if we can do something to fix it?

Why would you cancel coverage on FakeSpot? This was a tool used frequently by multiple people that I knew, and what it really feels like is that FireFox is being bought out and removing it to make it easier for all of the scammers to continue to pump us full of fake garbage. Really disappointing to see this service being discontinued and hoping that you reconsider.

Hello! I've been seeing some strange behavior on firefox launch or on new profile launch. There is a popup during startup, can't see it on the screen but I can see it in tray. Is this normal or no? I observed it on two different hp notebooks so far.

I have created several groups (currently 4 with a total of 11 tabs combined). When a group is closed, do those tabs become inactive, reducing their impact on Firefox/computer performance, or do they still remain active and impacting overall performance?
