With FF57 coming out, the current ABP 2.9.1 wont work anymore and ABP 2.99.0.xxxxbeta is in current development and use for WebExtensions.
I have tried the WebExt beta versions of ABP but I really miss the easy handling of filter subscriptions and custom filters (both in filter preferences) as well as their specific count on blocked items per filter.
I also miss the integration of the ABP monitor in the new beta versions.
Will there be an addition where these items can be seen as well as the integration with the monitor (which would have to be WebExtended)
*Edit:
It took me a while to find what I was looking for.

Some of the aforementioned items are there, although not easily discernible, and there is still some differences that the original FF version had with the blocked filtered item count, although it seems that this is not going to be implemented, since it has an effect on performance according to development-builds/bringing-blockable-i ... ools-panel
