FIRST, I realize that Mozilla/Firefox is NOT responsible for updating/maintaining any add-ons they did not create, so this is NOT a misplaced crybaby gripe about something you (the Mozilla developer team) have no control over. HOWEVER that being said, the GET ADD-ONS interface IS your responsibility. It appears that many of the old add-ons are no longer even viewable in the GET ADD-ONS search results. This is a problem that you can (and IMHO should) solve. I think it would be worthwhile to make a semi-static website with the last available versions of each of these legacy add-ons available for historic research and practical usage. WHY? Well, two good reasons... 1. Abandoned add-ons sometimes inspire new features and forks by other active developers. The next generation of yet-to-join-the-mozilla-community developers should be afforded the opportunity to browse and play with these artifacts of early Firefox culture. Also there are those who do what might be called software archaeology and such an archive would be a great "dig site" for them. 2. Some users (including myself) use certain add-ons that are an interface to or have uses with other things besides the internet. In my case I have been using the (now legacy) add-on called "Scrapbook X" and have a rather extensive collection of captured pages organized by the add-on. The problem is I need the add-on to be able to pull up these archives for my research. My (planned) solution is to use an old version (45) of Firefox PORTABLE that I still have on a thumbdrive strictly to open these archives but I need to install the legacy add-on to that thumbdrive and I cannot find it anywhere in the GET ADD-ONS search results. I know there is a new ScrapbookQ add-on but it doesn't work with my old archives from ScrapBook X. So how about cloning the old GET ADD-ONS website, blocking any updates or uploads, and putting it back out there on a new subdomain like "legacy-addons.mozilla.org" ?? PS: I assume nothing, but completely removing these old versions feels a lot like an effort to try and force people to upgrade their browsers. In the past they were simply flagged and blocked from installing to wrong versions. I know the improvements in Firefox are beneficial and even necessary -- but -- which version of the browser I use is my decision (and in my case my necessity) to deal with. Please do not let Mozilla become a shadow of the dreaded Microsoft Monster that tells users they MUST upgrade or die. Thank you.
