I used the 5.5 betas for about the length of a trial period and ended up coming back to safari. I miss site preferences, its speed advatage, the lightweight look, tab thumbnails (Stand does nothing but annoy me...) everything. except ad blocking. I know everyone is like "it works fine, you just need..." and on the list are a perfect blocklist, because if one thing isn't a regex OW can understand the whole thing goes down the tubes. Also there is custom CSS and other things I have heard. Why can't this just be simpler, like everything else in this app seems to be. Why can't I just put the filterset.g text file in line by line (As I spent time doing) and expect it to work? I keep my ow5 prefs file, and I will be trying out new OW releases until omniweb's ad blocking, like everything else on my mac Just WorksTM. Once it does, I will be delighted to switch back.
