Q/A work needed to thoroughly test functionality on website

Hi we have a website that we want to get thoroughly tested for Q/A. We want it to be tested on Internet Explorer and Firefox on Windows, Mac The important combinations are (in order of importance) 1. Firefox/Windows (firefox 2 and 3) 2. Internet Explorer/Windows (XP and Vista) (IE 8 and 7) 3. Firefox/Mac 4. Firefox/Linux If there is any combination you can't test, please let me know in the comments for this bid. The testing should involve (but not limited to) 1. creating accounts and going through the screenflow to uncover things like broken links, broken jsp pages, error messages, broken functionality etc. 2. stress test (rapidly click on links and see if anything breaks) 3. Test all the flows of control. For eg. we have an address importer. Test it by trying to import contacts from gmail,yahoo, msn and everything else listed. Check if the email gets delivered etc. 4. Test the formatting of our search results on [login to view URL] (we have a widget that displays our results besides google search results. you need to download our toolbar for this). Test this for all the browser/OS combinations mentioned. 5. Test functionality/features in the toolbar 6. Any other look and feel bugs relating to formatting that is buggy/inconsistent in certain browser/OS combinations 7. Also test it in a variety of internet connectivity conditions. For eg. dialup, broadband (weak connection vs strong connection) We'll be happy to pay an additional bonus based on the volume of bugs uncovered. We have found especially that on internet explorer, some of the times we get problems with broken jsps, registration failed. This will need to be thoroughly tested. Brad
