firefox: classic addons (legacy extensions) archive

[Anonymous]

.
I have tested to confirm the Waterfox-oriented CAA addon is usable with firefox v52.9 ESR.
note: >>>>> I cannot vouch for (nor provide support for) the CAA addon nor any addons retrieved from the archive server.

FYI, each “xpi” file is a zipfile (renamed to .xpi so that the browser treats it as an installable addon).
You can, and I encourage, right-click “SaveAs” rather than clicking to install individual addons.
Once you have a local copy (which you can backup for safekeeping), you can
1) rename to .zip
2) extract and inspect/edit the contents (at a minimum, I edit “install.rdf” and blank the “update/hompage” URL string)
3) repack into a zip, rename to .xpi, and paste the file:/// URL of the local copy into browser addressbar to initiate installation

This post is just a note to mention CAA is still available, still effective.
I had occasion to use it today to grab a copy of the “Colorful Tabs” addon
colorfultabs-31.2.3-fx.xpi

The usage workflow:
— click browser “Classic Add-Ons Archive” toolbar icon
— browse/search the CCA. On an interesting addon’s description page, click the “Install” button
— YMMV, based on your configured browser prefs. For me, clicking “install” raised a “Open/Save” prompt
— save to /tmp/colorfultabs-31.2.3-fx.xpi
— type “/tmp” into browser addressbar, click the xpi filename displayed within the directory listing
— answer “yes” to the install prompt, and (optionally) “yes, restart the browser now”
