Almost exactly what I needed; the issue I have is that some websites don't load completely unless they're on the tab that currently has focus. This is an issue with Firefox/the websites in question rather than with this addon, but could you please change the reload tabs option to have a before/after dropdown rather than always reloading after?

Basically, I need it to switch to a tab, reload it immediately, wait for X seconds to hopefully ensure everything loads properly, and then move on to the next one.
