Diễn đàn hỗ trợ Firefox

Thank you for your assistance in advance. Since I updated my browser, I've encountered some issues when trying to maximize the virtual screen in my tv. I use a Mac and connect the screen to a web TV to watch YouTube in my big tv. However, when I click to maximize the window, the connection becomes unstable, and the virtual screen disappears every time I click the YouTube icon to do this. This problem never occurred before. I would appreciate your help in resolving this issue. Please let me know if you require any additional information from me.

Hello support,

is there any way (other than the one plugin I found that did not work for some reason) to adjust firefox' general brightness (or that of an individual tab) ?

Also changing my monitors brightness would not work for me as I am trying to test a website I develop (using firefox to visualize it) and it is rather just the large difference between my editor (which's brightness you can not adjust) and the browser that is very unpleasent when I switch back and forth (like when trying to fix a bug).

Kindest regards.

I'd like to organize bookmarks alphabetically, with folders listed first, at the top of the list, followed by bookmarks not saved to folders. How do I do this? An example: Folder A Folder B Folder C Acme Co inc Beta Corp, C corp ...etc
