Hey there,
I've recently switched to Update Scanner and I'm pretty amazed by it. I had been using Page Update Checker before and that required a lot more settings and also was pretty buggy (showing that a page has updated when it didn't really).
But one feature is missing from Update Scanner, and I'd like to request it here:
Please make a checkbox for every entry that allows you to select that a page is updated every time Firefox is started. That way at Firefox startup e.g. in the morning, all the new updates would be visible immediately and there wouldn't be any need to manually check all the entries.
I'm certain that this feature would help other users of Update Scanner, too!
