I'm not sure whether this is a Firefox thing or a WM thing (I use i3), but oftentimes if I press 'a' in certain Firefox text boxes, it will tab to a different element or finish what the textbox was doing. For example, in the browser version of Discord, when I perform a GIF search, if I try to search for "giraffe" it will find and send the first gif it finds with "gir". On a typing practice website, sometimes pressing 'a' will somehow tab to the "restart" button and hit "enter" on it so that I lose all my progress in the typing exercise. Sometimes, I can avoid this by waiting a few seconds after the textbox has loaded; other times, it will malfunction regardless of wait time. Not all text boxes act this way. Has anyone else experienced this issue?
