i am trying to type this message on firefox, but i have to avoid shift key not to interrupt typing. when i hot shift+some other keys like i, b, v, etc, devtools pop up. i have checked other forums, other q&a on firefox support, and concluded that the same issue have occurred to many users regardless of the os, features, extensions, various keyboards (but not the virtual one for me) or system settings. i have to type a lot in the browser, so i just choose to delete firefox until someday the issue is fixed.
