I can't install extensions anymore, when clicking on "install" button, the waiting icon keeps moving forever. I'm using firefox 115.20.0 esr 64 bit. Also tried in troubleshooting mode, no change. I've tried several verified extensions, and many that used to work fine precedently.

I accepted an update to my computer and immediately Firefox could not load, the exe file is missing. Again I use windows 7 . May have lost all passwords and bookmarks. Please advise.

Yesterday I was on the Newsmax website. Today Firefox says its not a secure connection and it won't let me go to Newmax.com. I then tried to use the google browser and it went right to Newmax.com no problem. I am using Windows 7 like I have been for years. Please help. Thanks, Al

When I am on espn.com/fantasy team pages everything loads correctly except for one popup table that does not. It will occasionally display but usually doesn't. When it fails to display, the scrollbar disappears but nothing shows. I tried clearing cache and cookies (Ctrl + F5, Settings + Clear data, etc.), refreshing firefox, and disabling all addons/extensions but the problem persists. I also tried turning off hardware acceleration and turned off proxies and secure DNS but nothing worked. I noticed this "_error.js" message in the debugger:

module.exports = __NEXT_REGISTER_PAGE("/_error", function () {

 var e = webpackJsonp(
   [566],
   {
     1789: function (e, r, o) {
       e.exports = o(288)
     },
   },
   [1789],
 )
 return { page: e.default }

})

I do not have this issue on firefox android, only on desktop. Thank you.

Firefox will not open this website (it is my personal photography website.) I'm using Windows 7 64 bit. Seemingly, every other website, but this one will open using Firefox. I have always been able, to use Microsoft's browser, to open this website, except, now, they no longer support W7/64. Thanks, for any help, David Johnson

Hi, I want to use dark background color theme in the Mozilla Firefox PDF viewer, read here https://support.mozilla.org/en-US/questions/1434510 but cannot find "userContent.css". My question is where can I find this file on a Windows 7 or Windows 10 installation?
