Hello - I have Windows 7 and the recent Firefox Version 115.16.0esr update. As of today, the Firefox start page does not open completely (no images) and I can no longer access the internet through Firefox (error message - can't connect to the server). This message is displayed regardless of the web page I'm attempting to access and the network connection is good. In Settings, under Firefox Updates, the allowed option is to Automatically install updates when Firefox is not running and I've restarted the computer. Is there a bug with the new Firefox version or does Firefox no longer work with Windows 7? Thanks

Just a few days ago, screenshot technique failed. I often copy an image from webpage. Right click technique. I am still able to do this. I have option of copy or Download. Download works but Copy does not. When I try to paste the copy into my Word document, I get a blank image (a square that indicates there was an image but the actual image is not there). How can I get the paste mechanism working again?

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

When open firefox I have problem , with may sites that appear and I cannot use it. The same problem I have on work and house with mozilla firefox 64bit. I checked my pc with antivirus and for malwares but nothing I have. Please help

YouTube hates Firefox right now. The problem is caused by the AdBlocker or the hidden AdBlocker included with Avast. Using a different Browser plays the video perfectly fine.

YouTube starts out with an advertisement and after 3 seconds, you can click skip to watch the video. If you don't get that message due to the action of an AdBlocker, yahoo will harass the user by repeatedly interrupting the p[playback of the video. There are hidden AdBlockes such as Free Avast which includes an AdBlocker automatically applied towards YouTube. So we have two issues here. The known AdBlockers and the hidden AdBlockers. Also YouTube is behaving badly towards Firefox users even though we didn't do anything wrong. They just don't like Firefox users.

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?
