How to Fix Firefox Right Click Strange Behavior In Ubuntu

I'm not sure how many of you face this issue but whoever does i'm sure would be really frustrated by it . Firefox had this major bug which seemed to have affected only ubuntu 8.10 machines ( maybe 9.04 also , not sure ) . So its probably a ubuntu bug more than a firefox bug. I have been facing this issue ever since i installed 8.10 . I always thought that this is a noticeable bug and it should be fixed soon . But even after so many months , this still hasnt been fixed . The bug works this way . Whenever your on firefox and you right click on a click to say "open in a new window " or "open in a new tab" etc firefox tends to act really weird . As in , sometimes it would open evolution , sometimes it would open a save webpage window etc . But sometimes it would work fine . But this was really frustrating at times . So if you too face this issue , here's how you fix it :

Here are a few screenshots of the bug acting :





THE FIX
The fix is pretty simple and pretty weird just like the bug :) . The fix is to install a firefox plugin called mouse gestures.Once i installed that i found that the bug completely vanished . So here's how it is done :

Step 1 : Open firefox and go to THIS LINK.
Step 2 : The mouse gestures page should now open , now click on ADD TO FIREFOX

Step 3 : THen go ahead and start installing the plugin
Step 4 : Once done , click on the RESTART option given by firefox


Step 5 : THats it , once firefox restarts you should no longer have this problem!!
