One of the best features of Firefox 4 is the entirely re-designed Add-ons Manager that displays more details than ever before about the add-ons you have installed. Screenshots, ratings, reviews, detailed descriptions, and even support for Contributions are all included. In order to power this feature, Firefox checks the AMO<\/a> API once a day to ask for any updated information about your add-ons, including add-ons that may not be hosted there.<\/p>\n

We love add-ons and want everyone to discover how customizable Firefox is, but we also know there are some add-ons that cause extreme slowdowns in Firefox because of poor coding practices, in extreme cases adding 30 seconds to start-up time. Unfortunately, we usually don’t learn about these problems until it’s too late and already affecting a large number of users. That’s why we recently modified the daily add-on metadata ping in Firefox 4 to also include how long it last took Firefox to start up. With this new information, we can identify add-ons that are causing significant performance problems in Firefox before they become widespread problems, and work with the developer to correct the issues.<\/p>\n

User control and respect for privacy are fundamental to Mozilla’s mission, which is why we’ve explained this in the Firefox Privacy Policy<\/a> and offer an easy way for users and developers to opt out of this metadata ping<\/a>.<\/p>\n

We hope you enjoy these new features of the Add-ons Manager and look forward to improving the Firefox experience for users with slow add-ons installed.<\/p>\n","protected":false},"excerpt":{"rendered":"
