Comment 2 for bug 957165

After reading the comments on bug #872207 I do not believe that this is a duplicate.

The context menu displays & functions correctly in all cases bar web page hyperlinks.

The context menu elsewhere is seemingly triggered on Right button keyup event then desired action can be selected by Left button keyup event.

However, with hyperlinks, the context menu is triggered on Right button keydown event & action fired on Right button keyup event. This gives the impression of the menu not appearing and the default (first in menu) option automatically triggering.

Therefore, you can achieve what you desire by not releasing the Right button and moving mouse over required list item & then releasing Right button on selected item. This though is not consistent with the rest of the application or what was the norm prior to firefox 11
