This module is a simple qa tool that installs extensions and tests whether the
browser crashes while visiting a list of urls.
Usage: python extensions.py -v
Note: This assumes that there is a directory of extensions in called
'extensions' and that there is a file of newline-separated urls to visit called
'urls.txt' in the same directory as the script.
