Need help with the installation of jre for firefox
I have invested about 2-3 days trying to fix some problems with this notebook & one of them is successfully installing jre for FF &/or SM. I was reading in this forum & learned where FF was looking for plugins but those posts were old ones. Even though they might not apply to me now I checked in /usr/lib/mozilla/plugins for the flash .so file & it was there. FF refuses to play Youtube videos, web-radio sites nor other sites offering video.
I've tried the manual installation feature within FF>Tools>Add-ons under plugins + From File but it always says "could not install due to corruption...", or something like that.
I'm using PL528.005 OS, FF 11.0 (d/l from the repositories?).
Any help on doing/completing this task? Thanks!
