the only difference comparing to the original script (thanks, Ben) is that shortcuts are changed in order to make the script work with the "Find as you type" Fx's feature enabled.

Changelog:

0.9
new keybindgs are the following:
press F1-F1 to enumerate links;
press F1-# to open the link number # (e.g., F1-5 opens the link number 5);
and press F1-F2 to open the url of the original message.

0.91
found some crap in the script. fixed and does work now.

0.92
due to some Google changes F1 stopped to work. therefore F2 was changed to F3, and F1 to F2 accordingly. i.e., the new settings are the following:
press F2-F2 to enumerate links;
press F2-# to open the link number # (e.g., F2-5 opens the link number 5);
and press F2-F3 to open the url of the original message.

0.93
F2-F3 shortcut changed to the single key 'y'
i.e., press 'y' to open the url of the original message in the new tab.
