Right-click menus of Writer and Firefox overlap

Right-click menus of Writer and Firefox overlap

It is very inconvenient that whenever I highlight and right-click on text in Writer, both Writer's and my browser's (Firefox 2.0.0.11) right-click menus appear but are overlapping. Since Writer's right-click menu is always the one underneath, it requires a lot of highlighting, right-clicking, and scrolling-about until the feature that I would like to use finally becomes accessible.

I would not like for either of them to be disabled because I use them both very much. Is there a way that I can toggle between the menus so that only one or the other appears? (E.g. Right-click enables the browser's menu, and Ctrl + right-click enables Writer's menu)
And if not, might I kindly recommend that such a feature be added as soon as possible.

Thanks in advance!
