Justin, the developer of Chinese Pera-Kun for Firefox, has released versions of the plug-in that work in Firefox 3. If you’re running the current beta of FF3, check it out.
There are also some new features in the pipeline for perakun that sound pretty cool.
Justin’s put up a donation button, so if you’ve found perakun helpful think about sending a few bucks his way to support independent (free) software!
