Hi Michael, this is the result of a preference change in about:config -- I use it myself, actually. On Windows, you can peel off Firefox's menu from in front of the site's menu by tapping the Alt key. No idea what method you would use on Linux. If you want to go back to letting sites preempts/override Firefox's context menu, here's the setting you need to change: (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button accepting the risk. (2) In the search box in the page, type or paste '''context''' and pause while the list is filtered (3) If the '''dom.event.contextmenu.enabled''' preference has a value of false, double-click it to restore the default value of true More info on about:config: [[Configuration Editor for Firefox]].
