Personalized Web Plugin for Firefox?

[Meomix]

I couldn't find Google Chromes "Personalized Web" plugin for Firefox, is there an equivalent?
Cause i need the plugin where i can paste in this code to make the bakabt forums show properly on a 1024x768 monitor.

Ok wow.. somehow the plugin worked like magic even doe i couldn't specify what website to edit.

Edit: hmm hmm, to specify a site you have to specify it in code. Mah it all worked out anyway, thanks!

to only affect a specific domain/site bracket your code with:
@-moz-document domain("your.domain.here") {
YOUR CODE HERE
