, only a few days after going live with the final version of Firefox 7
. According to the announcement, the big changes this time around include the ability to use Twitter as a default search engine, more versatility in restoring tabs on startup, and improved user control over add-ons
. "Users will receive a one-time notification to review and confirm third party add-ons they want to keep, disable or delete. When Firefox starts and finds that a third-party program has installed an add-on, Firefox will disable the add-on until the user has explicitly opted in, giving users better control over their Web experience."
