Instead of an install button, add-on details pages now have a button (or link) that reads "View Version History." This link takes you to a new page, which lists the most recent versions of an add-on, and offers install, convert, and/or download buttons when appropriate. For example, for a Firefox extension, you can use this page to check whether older, non-WebExtensions versions exist, and try to install them.
The extension also includes its own alternate search page; click the link labeled "use the AMO Browsing extension to search" under AMO's search box. This type of search includes Firefox, Thunderbird, and SeaMonkey extensions. (You can also keep using the search page on AMO if you prefer.)
The Development Channel lets you test an experimental new version of this add-on before it's released to the general public. Once you install the development version, you will continue to get updates from this channel. To stop receiving development updates, reinstall the default version from the link above.
Caution: Development versions of this add-on have not been reviewed by Mozilla.
