Rated 3 out of 5 stars

I've finally found ClipUpload (all other tools discovered don't work anymore)

Doesn't work in FF8 Rated 3 out of 5 stars

Could anyone give a hint how to fix this? Would immediately download Nightly Tester Tools

Thanks "addons user" — works perfectly again, though Nightly Shifter Tools was a quite good workaround (transparent context menu bug :)
Thanks a bunch from Berlin!
