Hello! I have a problem with my latest version of firefox for windows 10. The problem is if Twitter.com is opened in the currunt tap and i do want to visit other website from the bookmark, firefox will not take me there. and i have to click again to go there. This happen always on twitter. Other releated problem i want to report is the ALT key will not show the hidden menues if pressed while Twitter is opened. but it will work with other websites.
