I'm not sure why there would be leaks with ABP.  Afaik it doesnt send information.  However it does update its blocklists which might be language-specific, which splits the anonymity set (if i understand the concept).

Regarding use of ABP itself among non-Tor users, i have personally installed it on hundreds of computers every year while servicing them and updating Firefox. So i am sure the user base is at least as large as the TBB user base.

Perhaps there is a concern about ability to fix vulnerabilities in the code - who will do that and maintain it.  Do they accept patches?  It seems to use Mozilla Public License.

ABP itself has changed default policy to accept some simple text ads, on the grounds of keeping small well behaved websites alive.  Should we be worried about ad-revenue corruption and creep?
