I cant add anything new. When I first began using extension it was great. I entered all the pages I needed to migrate to firefox. Scheduled pages load but I cannot select a time thus making the extension worthless besides the pages already scheduled.

Many thanks to the author, it works great!

UPD: nope, sadly does not work for Custom Minute. I have Custom Minute urls, time set to 300, and it simply does not open any tab.
