why does firefox insist that i turn on caret browsing?
i keep getting a pop-up advising that pressing f7 turns on caret browsing to choose text in web-page using keyboard. this has no relevance to playing farmville or reading emails, the activities i am engaged in when the pop-up appears. deleting the pop-up only succeeds in multiple copies of it appearing so that i can not delete it, then the web-page freezes so that i can not shut-down firefox.
firefox 8 in kubuntu 11.10 on acer tm4152lmi laptop with centrino 1.73ghz cpu, 2gb ram & 80gb hdd
