Hi,
Thank you for reviewing.

Certainly, some users may want this feature but i will not add it. There are some reasons...

1. Firefox does not allow extensions reading the setting. It is one of personal settings.
2. I do not want to read personal settings. Because I think extensions should avoid reading personal settings as possible as it can.

I am really glad to get your feedback because nobody had reviewed this extension until you reviewed. It took a year ;_;. Thank you.
