WHAT IT IS:
Twitter Follower is a Chrome extension to make multi-following (or unfollowing) of twitter accounts easier.
HOW IT WORKS:
It simply adds two buttons to twitter pages: "Follow them all!" and "Unfollow them!".
If you use them, the extension will simulate you're following/unfollowing all the users/accounts on the page: it will scroll to the first "Follow"/"Unfollow" button, click it, then wait a for a few and go for the next one… easy!
It works with the members of a list, search results and twitter suggestions. Well, it should work with any page where a "Follow"/"Unfollow" button appears. 🙂
Scrolling and delay give twitter some time to load more & more accounts at the bottom of the page.
Now, it also lets you to "Stop" the action you began.
Doesn't worry about twitter limits (per day, per account,…).
Doesn't work if an account you try to follow is suspended.
