This is the Linux version of this question. Does anyone have a method for forcing a page refresh on firefox from the command-line?
You can use xdotool for automation. Install on Ubuntu with
sudo aptitude install xdotool
Then you can search for windows and send keys or mouse events, see man xdotool
for the full documentation. I use following script on Ubuntu 10.04 LTS during development:
WID=`xdotool search --name "Mozilla Firefox" | head -1`
xdotool windowactivate $WID
xdotool key F5
