How to ensure that your extensions work on Firefox 3.0

Here are the steps that I found useful to port my extensions from Firefox 2.0 to 3.0:

  • Step 1: Just start Firefox and allow it to update the extensions. You could go to: Tools -> Add-ons -> Extensions -> Find updates.
    This should update many of the extensions. Restart Firefox.
  • Step 2: For those extensions where the auto-update has not functioned properly, you might want to manually see if an update is available. This is because for some extensions, the auto-update may not recognize that a new version is available.
    • Uninstall the older version and restart Firefox.
    • Search for the addons here and add them.
  • Step 3: Install the MR Tech Toolkit extension.
  • Step 4: For those extensions that have still not been updated and you need desperately, just see if the option 'Make compatible' from MR Tech. This option is available when you right click an extension in the Extension tab. If the compatibility range is upto some older version of 3.0 (for example 3.0b5) then this might work.
  • Step 5: Look for updates at a higher frequency over the next few days. Developers will be forced to ensure that their extension works in new version of Firefox so you can expect an update soon.
