In April, I posted here asking people to write to the Weight Watchers\nwebsite because it oddly blocks Mozilla on it's home page (despite the\nfact the site works perfectly if you start with link within the site).\nTheir .co.uk site has fixed the problems, probably due to in part to\nour complaints, but the .com one is still screwed up.\n\nI've been using Firebird 0.6.1 lately, and to my surprise Weight\nWatchers doesn't have a problem with it! I diffed the browsers'\nrequests. Firebird's "Accept:" line includes "video/x-mng,". Here's\nthe only other difference between Firebird's request (first) and\nMozilla 1.5a (second):\n\n\nUser-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5a)\nGecko/20030728 Mozilla Firebird/0.6.1\n\nUser-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5a)\nGecko/20030718\n\n\n10 days in the build date, and the words "Mozilla Firebird/0.6.1" are\nthe only differences. Again, Firebird works, Mozilla is blocked. I\nknow this sounds paranoid, but does this mean the site is specifically\nand intentionally blocking Mozilla?\n\nThanks,\nDaniel J. Bell\n\nP.S. Thanks to Brandon Blackmoor his example for a Mozilla-blocker\ncomplaint post.
