Hi. I have problem with almost everything with firefox 1.5.0.7 on Suse 10.0

First, I cant make it open .pdf files. Plugin doesent work, and if I want to call for adobe in the "download actions" I imidately come to the second problem. The Firefox also does not see directorys which are not in home (and acroread is in
/usr/X11R6/bin/acroread) and also does not see the files which are deeper than 2 levels in directory tree of my home (for example /home/Clanci/Wiki_Clanci/WikipediaPRE.pdf is not available).

I have put my user account in the root group, but it doesent work. Mozilla works fine, but I dont want to switch to Mozilla just because I dont understand problem with Firefox...)

ps. sorry on bad english
