Flock, the social web browser that was purchased by Zynga earlier this year, has announced that it is shutting down. The team will instead focus on helping Zynga build socially connected games across multiple platforms. If you’re a Flock user, the good news is that you’ll be able to continue to use the product for a few more days as you transition to a new browser. Flock says that, after April 26th, key features will no longer be available, and it also warned that security will falter without future software updates or upgrades. The team recommends that current Flock users switch to Firefox or Chrome. Hit the jump for instructions on how to migrate your favorites and other features to a new browser.
