This website is a repository for web content that has been deemed
"legacy" and has been removed by their original publishers, and might
otherwise be difficult or cumbersome to get.
This is still a new effort, so we will be growing our site with more
legacy content submitted by users over time. This was primarily started
to give people access to the "legacy" Firefox extensions people still
want and need, but Mozilla has completely purged from existence, but we
can imagine there are others with archived versions of things they got
a long time ago, which are still useful, but are very hard to find by
Important usage notes for this website
- This archive will be here for a very long time to come. Please don't use scrapers or site copiers
to make a "local copy" of this website -- it is many GB of data and
using up that bandwidth from our quota just so you can have a copy of
the archive is disrespectful to others who need access to these files.
Expect detected scrapers and bots to be blocked. Only download the
files you personally need, please, and keep it manageable to keep
running this archive free of charge to everyone.
- Please note that we generally cannot host very large items due to
bandwidth limits at this time. The wonderful folks at archive.org are probably a better
match for you in that case.

Mozilla has removed all "legacy extensions" from their add-ons site in
November 2018, leaving many users of older "long term support" versions
of the browser, as well as browser forks, dead in the water. This holds
a (hopefully complete) collection of the removed extensions as they
were available from addons.mozilla.org prior to this purge by the
Note: an effort has been made to remove extensions that are not freely
distributable, but due to the large number of extensions involved and
this being a new project, it is possible that there are extensions
listed that should not be here in accordance with our content policy. Please get in touch if something is in violation of
your rights and it will be removed ASAP.
Submitting new collectables:
If you want to have new collectables added to this site, the best way
is to first verify that it meets our content
policy. We have no desire to break any laws or disrespect
authorship and its rights, so only items that had been freely available
are eligible. We do not host content that is either in dispute or
closed by Copyright without licensing to release it otherwise.
