Hello! I have a problem with Firefox. Whenever I have selected text and I press the control key, that text becomes unselected. Is like I lost focus of the window or the input text when I'm pressing the control key. This is really annoying because it makes copy and paste really complicated. Most of the times I have to select the text and right click - "Copy" instead of a simple "Control + C". This only happens on Firefox, as on Chrome the control key works as expected. I'm on Linux. Any help will be greatly appreciated, thank you so much!
