Still (even with extensions.checkComptability=false)
no positive score. Try www.ard.de and www.zdf.de

Yet- some gains when disabling both Pipelining and Proxy pipelining. Better to just work with about:config.
No need for this "tool"

All in all, a poor tweak.

This review is for a previous version of the add-on (1.3).
