Thanks, it works here.
I noticed that the about firefox still says 19.0, but after restarting the pandora it now shows 20.0
And I still cant get xmarks to install. It says
"Xmarks could not be installed because Firefox cannot modify the needed file"
Is it a permission problem? Or is there a way to install it manually?
I tried some different firefox versions and xmarks versions, but still the same problem. I did try the Slackware OS that comes with firefox 18.0, and there xmarks installed and synced without problems.
