Comment 183 for bug 263435

Isn't that behavior what happens now? If you hand a key press event over to a plugin, how will the plugin to "give it back" if it doesn't know what to do with it? AFAIK Firefox has no way of knowing whether a plugin actually did something with the event, or whether it just swallowed it. I don't want to rely on plugin developers to make their plugin hand back unhandled key presses.

Regardless, I think it's pretty crummy to let plugins hijack shortcut keys. I would rather my browser behave consistently on every page no matter what content the page author has elected to place on their page. I can't see how it can be considered a good idea to shred the consistency of the user's experience and make the same shortcut keys produce radically different results from page to page. To make use of this, the user will not only have to know what plugin currently has the focus, but have memorized that plugin's particular list of shortcut keys. Hijacking my shortcut keys isn't any different than hijacking the size and/or position of my browser window or throwing unwanted popups IMHO.
