Disable keyboard input via FireBreath plugin on my web page

Question

Can i somehow disable all keyboard input for user on my web page via plugin on that page? (plugin written with FireBreath)
I don't need it to make user unable to input in some specific input field (I know, that it can be achieved another, lot more easier way), I just need to totally disable some keyboard keys input for web page, containing my plugin object, for some time.

No you cannot. Pretty sure ActiveX controls cannot do this (in IE) and NPAPI plugins cannot preempt the browser in this way.

I guess there might be some possible way to do it using windows system API calls, since you can get the browser HWND, so maybe you could hijack the winproc, but I think you'd find it to be pretty fragile -- not to mention you'd likely tick off the people who maintain the browsers' plugin blacklists... Anyway, there is definitely no "normal" way to do it, so if there is a hack that would work it would involve some fairly complex API programming and is way beyond anything I know how to do. You'd want to ask that as a windows api question instead of a plugin question.

On Mac there is absolutely no way to do it, since you have no way to access the window for the browser. Linux is anybody's guess, but I suspect there is no way there either.
