i think my fiefox installation is Ok. i do not notice any problems.
+ i tried to reinstall it this morning. i made a clean installation and currently
GM is the only extension i have.
i checked about:config and i see 3 entries
relates to GM
greasemonkey.editor /home/arkady/temp/butler.user.js
greasemonkey.enabled
true
greasemonkey.version 0.5.1

/home/arkady/temp/butler.user.js is a
script i downloaded from the home page and this file exists  adn all permissions
are set. what is wrong in my steupt ? 
what do you mean by "editor" ? path
to any text editor like gedit ? 
thank you, akrady
