Firefox 80.0 Changes
New Add-ons Blocklist
Firefox 80 is the first version of the browser that includes the new add-ons blocklist. Mozilla maintains a list of problematic browser extensions, e.g. malicious or privacy-invading ones, that blocks included add-ons from being run in Firefox.
Core benefits of the new blocklist are that it reduces the time it takes to load and parse the blocklist significantly.
The new blocklist mechanic is also introduced in Firefox ESR 78.x, one of the few instances that an ESR version gets a feature update with a minor update.
You can check out documentation on Mozilla's add-ons blocking process here.
