every time i use the shift button for anything / at any and all websites, the scratchpad pops up-- and i cannot continue whatever i was doing. i would like to know how to disable these developer tools as i have no use for them ... please help. this bug is driving me to think of just giving up on firefox completely. i can't post, write properly, even punctuation is affected. which is why this is written all in lower case 'exclamation point'
