I need to enable a plug-in in Konqueror but when I open the Configure Konqueror under settings there isnt a tab to control the plug-ins. I also have Ubuntu on the same machine and I was able to do it there. Is there a different procedure in Mint or am I just missing something obvious?

a guess - do you konqueror-nsplugins installed?

No I havent installed it in Mint. I didnt in Ubuntu either but it may have been installed by something else.
