Just throwing out a +1 for a Safari alpha public release. I'll keep my eyes on this thread until I hear more
I recently switched from Chrome to Safari after getting a Macbook for performance/system integration reasons, and I miss ABP so much. I remember how hard the switch from Firefox to Chrome was before ABP. Fortunately, I didn't have to wait long, and it seems that I won't have to wait long during this browser switch either.
I would say that most of us here on the forums would be willing to test any release that we can get our hands on, including unstable and broken code.
You guys are the bomb and ABP is the best web feature on any browser. Thank you guys very much for the hard work, and I hoped you had a wonderful holiday season.
