I can not access any website starting with https://. I don't see an error message, but an ugly set of characters that look like a wrongly decoded page (ex: x��?�o�6���?47�?,�I��mvԠ). It is happening for 2 weeks and initially it happened only with some websites (like twitter), but now it happens to all, including gmail that used to work till today. I tried to delete history, cache, disable all addons, even antivirus... but still not working. Can you please help?
