Link on website to Firefox Add-ons no longer work

[alreadydone]

Link on http://www.xuldev.org/firegestures/ to https://addons.mozilla.org/en-US/firefox/addon/6366/ doesn't work now. Seems many add-ons are removed from the site recently, mostly ones incompatible with latest Firefox?

Mozilla 已经移除了全部没有迁移到 WebExtension 的老版本扩展。
目前体验最好的新版鼠标手势大概是 https://addons.mozilla.org/firefox/addon/gesturefy/

Thanks for the reply. I've tried Quantum for a while but have long given it up due to unusable APIs for tab and session management making every WebExtension based on it unusable no matter how much efforts go into them. I cannot think of other words than 倒行逆施 to describe Mozilla‘s acts.

It's now a problem where to find these "legacy" (I'd rather call them classical) add-ons useful still for Pale Moon, Waterfox, Basilisk, etc. PM has an add-on site but doesn't seem to host a complete collection. https://github.com/JustOff/ca-archive seems to be a nice collection.
