Firefox Addons: Custom addon does not run

Question

PS: My problem changed a little bit. In the first post you see my original problem, please see #4 for the current one.
Hey everyone,
to collect some traffic data I call Firefox from a bash script. I use a proxy to connect to the loading speed is rather low. To be sure to collect all the traffic of the http connection I issue a sleep command (currently set to 60s to be sure, but some sites are loaded faster). 60s seems to be ok, but the script runs in a loop (250 to 500 iterations) and this means hours of waiting. Is there a command or trick how I can find out about the status of the website?
I thought of capturing the traffic twice, using one instance for the real data and one instance to measure inter arrival times and stopping if the time differences become too big. But this slows down the capturing (at least in my setup) and I can't be sure that the data isn't falsified.
There is the page loading symbol on each tab. An API call to request this information would solve my problem but I haven't found such a thing.

Answer 1

You could write a little chrome add-on ('chrome' means that the add-on has full access to all Firefox APIs) using JetPack which listens for a tab to finish loading and eventually creates an empty file on the local file system. In your script, you could wait for this to happen using inotifywait from inotify-tools.
Perhaps there are more elegant ways to go about this, but I am not really familiar with Firefox or JS internals.
