Manifest v3 update

We will introduce Manifest v3 support for Firefox extensions. However, we will diverge from Chrome’s implementation where we think it matters and our values point to a different solution.

Good news for uBlock Origin users

Google has introduced declarativeNetRequest (DNR) to replace the blocking webRequest API. This impacts the capabilities of extensions that process network requests (including but not limited to content blockers) by limiting the number of rules an extension can use, as well as available filters and actions.

After discussing this with several content blocking extension developers, we have decided to implement DNR and continue maintaining support for blocking webRequest.

Apart from that it is worth to read Raymond Hill post:

Maybe, maybe not. At least for the time being it's good news, I guess.

We will support blocking webRequest until there’s a better solution which covers all use cases we consider important

(emphasis mine)

Let's hope for the best. With the Mozilla devs you never know what they'll consider important and what not.

For the last few months, we have consulted with extension developers and Firefox’s engineering leadership about our approach to Manifest v3. The following is an overview of our plan to move forward, which is based on those conversations.

I try to more optimistic about foreseeable future.
