As many people have noted, the bug tends not to appear for a while. Then when it does, it is usually triggered several times in a row. A way I found to make sure the next click does NOT trigger the bug when such an accumulation appears, is to keep the right mouse button pressed for a second or two on my next click, then release it. That brings up the context menu pretty reliably.
I also think the "accessibility" thing has been mistakely interpreted as a workaround.
Even if this is not technically a Ubuntu bug but a Mozilla bug, it would be really cool if the Ubuntu bug squashers could fix this as apparently Mozilla hasn't for a LONG time!
