The new "add-ons blocklist" of Firefox
Mozilla has been blocking extensions that cause stability or security issues with a list of unsafe add-ons since at least 2008.
Starting with Firefox 80, the web browser will use a new and more scalable version of this exclusion list, which will reduce the time it takes Firefox to parse.
"As soon as we realize that an add-on is contrary to the expectations of users or endangers the privacy and safety "We're taking steps to block them using a mechanism called 'add-ons blocklist,'" said Stuart Colville, project manager for the Firefox Add-ons project.
Firefox disables extensions using three types of "blocks", based on the severity of the issues that cause.
The current list of blocked add-ons due to serious security, stability, or performance issues with Firefox is available here.
