Hi, guess_browser_version function in http_request.py has troubles with view Mac browsers: - Safari and OmniWeb are incorrectly detected as 'Mozilla': - Camino, Netscape and Firefox are (incorrectly?) detected as 'Mozilla' Opera, Mozilla and IE are detected properly. Here're all user-agent strings: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; nl-nl) AppleWebKit/125.4 (KHTML, like Gecko) Safari/125.9 Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US) AppleWebKit/85 (KHTML, like Gecko) OmniWeb/v558.46 Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.2) Gecko/20040825 Camino/0.8.1 Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; nl-NL; rv:1.7.2) Gecko/20040804 Netscape/7.2 Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7) Gecko/20040614 Firefox/0.9 Opera/7.51 (Mac_PowerPC; U) [en] Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; nl-NL; rv:1.7) Gecko/20040616 Mozilla/4.0 (compatible; MSIE 5.23; Mac_PowerPC) Ksenia.
