Comment 149 for bug 187313

Since people are still having trouble, I'd like to remind you of what gerben wrote almost three months ago:

>A simple way to get rid of this "functionality" in Firefox is to install the Mouse gestures add-on, even if you don't use the >gestures, this add-on will make the right-mouse-button-menu only appear after you release the right mouse button.

I know it's not pretty, and it's certainly not a bugfix, but it's about as simple as workarounds get. Disable the gestures unless you really want them; it still works. If this doesn't work for anyone, can you please report it?
