I'm working on developing something using Codepen and when I refresh either the pen itself or the browser completely the pseudoclass selector for `:hover` does not work. It does on first page load when I open (or open and then close) the browser.

Example: I am trying to style a `
  • ` and it's child. I open the pseudoclass selector and check `:hover`. I have a setting to change the display from `display:none` to `diplay:inline-flex` on a child when the `li` is hovered. It does not do this if I refresh internally (in codepen) or if I refresh the browser itself. It works again once I close Firefox and reopen altogether. I am including two screenshots of the working and not working states. The first (firefox-devtools-bug1.png) shows working, and the second (firefox-devtools-bug2.png) shows the not-working state.

    Certain sites like clyp, soundcloud, bandcamp, etc don't work on firefox yet, they work when I try them on Chrome. This issue of audio not playing correctly is becoming an increasingly annoying issue for me as I have started school where listening to mp3 files on blackboard is part of the curriculum. None of them work on firefox and, I've had to email professors to reissue quizzes to me.

    Recently my laptop was fixed by Dell (under warranty) and its motherboard was replaced. Since then tabs crash from time to time, a few time every hour. Sometimes upon opening a new URL sometimes while working. It writes "Gah. Your tab just crashed." Sometimes clicking "Recover" helps, sometimes it crashes again and I need to click it more times. It can happen in many varied sites: Whatsapp web, Google Docs, Gmail, eCommerce website and so on. I updated my Windows update, my Firefox and the graphic driver to the latest version, with no help. Here are a list of a few crashes happened during the last hour or two: bp-9de44d6a-3a90-4783-a7d3-c93180200922 bp-049c5dc5-b7fe-4833-aca2-a33c70200922 bp-d895ec6c-04d8-41c2-877f-85d720200922 bp-08c846e9-dd3a-4281-9d5d-72d8a0200922 bp-d476bbef-f778-4d8e-a764-f9d4f0200922 bp-22dce83a-48bb-45ad-9a0d-06cb40200922 Your help trying to find the problem and fix it is most appreciated!

    I have Adobe Acrobat PRO DC installed. Under Print > PDF there are multiple menu items saying "Save as Adobe PDF". How do I edit this menu ('edit Menu' has no entries) so that it only has 1 option to select not 4 saying the same thing?

    I have fully reinstalled Acrobat and Firefox, after uninstalling with App Cleaner and Uninstaller... the 4 entries remain.

    I am using Firefox 78.3.0esr on MacOS 10.15.6 and the latest version on Acrobat PRO

    Hello! I have recently installed Xubuntu Focal Fossa, and noticed that Firefox became slow along the way. At first, I didn't know what was the reason, but now, after having purged it and reinstalled it again for the second time, I am pretty sure that it is disabling the title bar which is causing the problem. Enabling it again and restarting the browser makes everything smooth once more. Is there a solution to this? Thank you very much!

Error details: TypeError: NetworkError when attempting to fetch resource. Troubleshoot issues with Microsoft SharePoint Foundation.

    So recently I've noticed that I get lots of problems with firefox and one of them being that when I use letter "A" in my brower it acts as tabulation or simply direct me to search engine front page instead of letting me write the search.

    Also I've noticed that on some sites when I'm interracting with input boxes or otherwise browsing I get some kind of dotted lines going criss cross on my browser which is really weird but so far have not caused any major issues. But regarless would be nice to not be there.

    Any ideas what's wrong and what I can do to fix it?
