Why does TextEdit box keep popping up while I'm using Yahoo Mail?
Ever since the last Firefox update, when I have Yahoo Mail open, a box appears: 'opening as.php You have chosen to open: as.php What should Firefox do with this file? This doesn't happen in Safe Mode or with Chrome or Safari browsers.
Additional System Details
- User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:69.0) Gecko/20100101 Firefox/69.0
Considering Safe Mode temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes) that might be causing problems, I would advise turning off any extensions that you use, one at a time, to see if the problem goes away.
