[solved] Firefox: “Could not find compatible GRE” after Ubuntu 8.10 Upgrade

After an update of my Ubuntu 8.10 (Intrepid Ibex) my Firefox didn’t want to start anymore.

This is what the command line returned after I started Firefox in there:

Could not find compatible GRE between version 1.9.0.1 and 1.9.0.*.

The solution for the problem was quite simple. This line made Firefox work again:

sudo xulrunner-1.9 --register-global

    could you start firefox in the command line, and post its output? Thanks.

    PS: pls don’t post your email-address, or you’ll be spamed. I’ve at least modified it a bit.

    for thin client like DRBL or maybe LTSP user…..it didn’t work……try this….

    - login as root
    - on server, copy files 1.9.0.*.conf and 1.9.0.*.system.conf to flashdisk……. these files location in /etc/gre.d/……
    - on client, login as root(i’m using DRBL) and copy 2 files in /etc/gre.d/…..don’t forget to change mode 644 for 1.9.0.*.conf and 755 for 1.9.0.*.system.conf

    try to run firefox……..

    i hope it works…….

    I had to do some funky stuff to install my lotus notes and pooched my gre file. Came across this post and it took care of it. Thanks sooo much!!! The one thing i had to do a little different was run the following

    xulrunner –register-global

    in /usr/lib which i imagine is the same place the xulrunner-1.9 is for other people.

    Thanks
