There are many video downloaders that work with Firefox 4, such as Flash Video Downloader (Youtube Downloader) and Easy YouTube Video Downloader.

For other add-ons you need to check with the developer to see if they have released any updates to their add-ons. For those that have no been updated you can check the Mozilla add-ons site to see if there is an alternative.

For the compatibility of many common add-ons see https://addons.mozilla.org/en-US/firefox/compatibility/report - those listed as either 4.0.* or 4.2a1pre will work in Firefox 4
