Right Click Misbehaves
On the latest version of Firefox quantum on MacOS El Captain, I am having a strange problem. Right-clicking anywhere causes the menu to pop-up then left click by itself unless I move out of pointer out of the pop-up while holding the right click button. This issue causes whatever is the first menu option in the right-click menu to be auto clicked whenever I normally right click anywhere on the browser window.
I have tried resetting Firefox completely I have uninstalled and reinstalled Firefox I have tried using a different mouse I have tried using Google chrome / Safari / Other apps where I do not have this issue I have disabled all addons
Still have the problem persisting.

I think I have figured out what was causing the issue. Since the toolbars and bookmarks bar font were looking very small for me, I had modified layout.css.devPixelsPerPx to 1.1 from the default -1 in about: config
And when I reset that to -1, the problem of auto left click after right click seems to have disappeared.

Can you reinstall your Video Card Drivers. I see a error in them.
Please let us know if this solved your issue or if need further assistance.
Hi, can you let me know if video card drivers could cause the problem only specific to firefox?
In any case, I am up to date with my software updates on a 2009 iMac with no problems whatsoever with video or graphics until now. So I wouldn't want to mess around reinstalling video drivers to test if right mouse click works as expected.

Since Firefox updated itself, I can't use right click and the only feature that works is the bookmark button None of the other features work
