Add-ons are one of the most important features of the Firefox browser and now Mozilla has released information on its upcoming add-ons manager that should be included in the next major Firefox patch. The main benefits of this new add-on manager is that it’s a local page, rather than a troublesome pop-out box, allowing it to be bookmarked and accessed easily, instead of having to wade through a series of menus. Developers are also allowed to enable silent updates for their add-ons, subject to user approval, of course. What add-ons do you use for Firefox, if any at all?
