Fix the plugin yourself, it's easy (did it myself before posting)
-download old plugin
http://4chan.wrathfilledhate.net/menu/4chan.v0.4.5.16.xpi
-right-click the 4chan.v0.4.5.16.xpi file, open with 7zip
-extract the install.rdf file
-open notepad, drag-and-drop install.rdf into notepad
-locate the line bellow (ctrl+F helps):
<em:maxVersion>4.2</em:maxVersion>
change it to...
<em:maxVersion>5.0</em:maxVersion>
-just save and exit, don't change anything else
-drag-and-drop modified install.rdf into 7zip window, save and exit 7zip
-drag-and-drop modified 4chan.v0.4.5.16.xpi into FF5, done!
