ignore system tabs

[robsonsobral]

Hi! You add-on is really useful. It helps me to improve my productivity.

Is it possible to make it ignore tabs whose address use the following protocols?

• chrome:
• about:
• resource:
• view-source:

Thanks!

One of the things I really like about your add-on is that is just counts the tabs when opening a new one. I can have 5 trillion tabs and set the maximum to two, what will force me to keep closing tabs for the next days without losing any of them, no matter how many times I close Firefox.

So, I guess that to check for these protocols on opening can be enough. I tried to find where on code to do so, but I don't have the experience needed for it.
