Help with adblockplus needed
 

Hi, I tried to install adblockplus to microb, but it seems I can't get it to work. I followed the instructions here, but now I'm stuck. It installed just fine, but when it asks to restart microb and I press the button, nothing happens. I've restarted the device and the microb quite a few times, but nothing seems to help.
On one thread there were mentioned that one should delete the adblockplus folder from /home/user/.mozilla/microb. So, how can I remove that folder?
I've never used linux, so any help would be appreciated.
