Hello. I don't know which Firefox release broke this essential feature. The problem started after I enabled Aero in my Windows 7 system. It happens often if I have an open tab with https://www.o2tv.cz/ which uses some DRM to play TV content.

Hi I am trying to change the default homepage Firefox logo to my own, but i could find no tutorial on how to do that. I only found 7-9 year old posts, that did not work. So my question is: Is it possible to change the default firefox logo on the homepage to my own one, and if it is then how?

As of two to three days ago (ca 20/05/22) when navigating to a website (regardless of whether it has been previously visited or not) a message appears stating "PK not found (e1)". I have to click it in order to view the website. Sometimes the message also has a checkbox stating "Allow notifications like this from www.example.com to take you to their tab". I am using the latest FFox 100.0.2 and am fairly sure the problem started after the update before the last one (the last one was this morning 22/05/22).

Hello there , I am trying to modify the menu-bar dropdown items when I hover over the list that opens with my mouse ( the dropdown list of any of Help , Tools , Bookmarks , History etc...). It is barely noticeable. I can hardly see the item chosen. I could use some help using the css. I am using FF93 and my platform is win7. Thanks look4
