Question

Hi! Have Mac Os 10.4.11 and tried many times to install firefox (wich does work) since required to drag icon into application and would load untill almost very end . Had this problem for months and could always use browser although at opening of computer would always ask to drag picture and did so quite a few time as new trial but to no havail. Since dragging didn't work, kept copys of both to keep bookmarks and now would like to either delete or uninstall one of firefox applications.

Might have been better sticking with one topic for this; could get confusing with two.
However; The only Applications icon in the finder window sidebar should be an alias to the Applications folder in the Macintosh HD (at least by default). I would suggest you just drag the one in the Places section to the desktop and watch it disappear, then go to Macintosh HD>Applications and drag that folder to replace the one you just removed - that will ensure that the correct one is in Places.
As for the one in the home folder, my new MacBook surprised me by having an Applications folder in the home folder, too; though as it's a new computer it was empty. So I can see how you might have one there, as it appears to have been part of the SL install.
What's intriguing though is how you come to have so many applications in that folder, including duplicates of some of those in the HD Apps folder. Are these Applications at the same standard of update as those in the HD folder? or are they earlier versions?
If they're earlier versions (and I'm guessing they may be), is it possible they've been migrated from a previous installation on that iMac during upgrade?
Whatever the reason they're there, if they're not required, trash them (from the home folder Apps folder) or indeed if there's nothing you actually want in there, trash the whole Applications folder from the Home folder.
The Dock behaviour sounds correct if two different versions of an Application are open, so you shouldn't see it again once you've removed the duplicated apps.
Whatever you do, *DO NOT* remove the Applications folder from Macintosh HD!
