I'm running Firefox 62.0 on Linux. I'm using the Light theme, but the menu bar and drop down menus have suddenly changed to dark. How do I get them back to a light background with black text? btw - when it changed, I couldn't read the menus because they were black text on black background. After trying a variety of themes, which didn't affect the menus, somehow they changed to black background with white text, so I can at least read them.

I am having the exact same problem listed here:

https://support.mozilla.org/en-US/questions/1224880

But none of the solutions there work.

Of course since I did not already have an account here, I was forced to create this duplicate question.

I was using Firefox fine all day, then suddenly Copy/Paste stopped working. Inside Firefox, the option for Copy still appears and can be selected, but when you Paste within Firefox or anywhere else on the system, things copied in Firefox are not available. Copying outside of Firefox works just fine. Using Firefox 62.0 (64-bit) on macOS 10.12.6

Update: And as soon as I posted this, now Copy/Paste is working, but only within Firefox; Firefox is now acting as if it has its own independent clipboard, accessible only within Firefox. This is happening everywhere within Firefox, regardless of website.

Until Firefox 62.0, I was able to pin separate taskbar icons for separate, simultaneously running Firefox profiles in Windows 10 by doing the following:

1) Add about:config boolean: "taskbar.grouping.useprofile" set to "true." (Described in this Mozilla bug-fix: https://bugzilla.mozilla.org/show_bug.cgi?id=577867)

2) Set target of each separate pinned icon to "C:\Program Files\Mozilla Firefox\firefox.exe" -p [user-profile-name] -no-remote

However, with the latest update these settings have no longer have the intended effect, and open instances of multiple profiles are grouped into one taskbar icon.

Is there a new way to pin separate taskbar icons for separate, simultaneously running profiles in Windows 10?

Every now and then, I get the 'Firefox Red Screen of Caution' about the site I'm attempting to visit. It's shown as a Deceptive Site, and I'm urged to NOT visit it. One option open to me is to 'Ignore Warning' and proceed. This works most of the time, but occasionally even clicking that option does not allow me to bypass Firefox's well-intentioned blockade and have to use an alternative browser. How do I deal with this otherwise?

How to prevent DOWNLOADING of video (not merely prevent autoplay) in Firefox

This may sound like word games, but I'm not trying to be funny, merely specific.

So I'm on a network with limited bandwidth. Therefore it's critical for me to understand what settings I can configure (if any) that will prevent the DOWNLOAD of video and/or large images from web sites.

For example, your basic site nowadays probably uses HTML5 and may use that vs. the old-style Flash plug-ins to embed video. And yep classic HTML links with references to image files for the images.

Back in the day you could configure a browser to ignore these references and then the browser would not even attempt to fetch the referenced image or video files. I've recently started using Firefox again, and I'm trying to learn how Firefox handles this in the HTML5 era (or rather what dumb users like me are supposed to do nowadays).

I'm noticing most of the help literature is regarding disabling settings of the auto-PLAY feature. However, due to my ignorance of modern Firefox, perhaps I'm reading it wrong, but most of it seems to involve disabling plug-ins that activate after the file is downloaded, not preventing the actual download. Similar to if I'm using Microsoft Word to view a DOCX file from a web site, uninstalling Word doesn't prevent the DOCX file from downloading. What I don't want to do is cheerfully disable the video playing while my browser still happily downloads the video in the background... because my main goal is not to avoid the annoyance of autoplay, but my goal is to conserve bandwidth on my connection.

FYI I'm using the latest version of Firefox Quantum on Manjaro Linux.

Thanks for advice anyone can provide in helping bring me into the "now" of modern Firefox, or who can point me to any further help articles or instructions to help educate me about this. If I'm over-reading and disabling auto-PLAY also inherently disables the downloading of the associated media, super, but that distinction is not obvious in any of the documentation I've seen so far.

Thanks!!

Hi - please help! I'm running Windows 10 on a Dell Laptop. Firefox won't shut down at all and every morning it asks if I want to restore the previous session. This is causing all sorts of issues. I've followed all the advice in the troubleshooting guide (ie updating windows, stopping fast start up, and everything else in the guide - as well as deleting and reinstalling Firefox) but nothing has worked. It's driving me nuts! Any help would be appreciated.

Firefox hangs when I open a new tab or new webpage. It's really annoying!

Everytime I do the automatic updates this shit happens. I used to go to one of the articles where it gave me instructions on how to reset my preferences, but that thread has since been modified, it now says to delete my pref.js, but that doesn't fix the issue anymore.

So i'm resorting to actually making a god damn account and asking why this shit keeps happening. I uninstalled Firefox and re-installed aswell, but it saved some of my data which I kinda need (bookmarks). That doesn't help.

I know that resetting my preferences back to default every update used to fix it, but I forget how now. Thanks...

Can someone just tell me how to fix it so I can update without having to do all this shit again.

I have only one extension and that is adblockerplus. Not likely the cause as it does this aswell without.

Hi Mozilla,

I am experiencing repeated crashes when opening Firefox (both standard and developer versions). The crash happens within 30 seconds of opening Firefox. The behavior just before the crash involves a slight hang, and then a crash.

I am able to debug with Visual Studio, and can see the following error message: Unhandled exception at 0x00007FF836A36FB1 (xul.dll) in firefox.exe: 0xC0000005: Access violation reading location 0x0000029F7A02DFDC.

I have tried many, many avenues, including: - Freshly reinstalling Windows 10 Enterprise - Running Firefox as Admin - Starting Firefox in Safe Mode - Refreshing Firefox - Reinstalling Firefox - Disabling/Enabling hw acceleration - Running a malware scan - Installing all necessary Windows updates

If I have some time, I will likely get the latest source and run it locally in debug. However, I am a C# dev, and not a C++ dev, so it may not be all that helpful.
