Firefox developer loses three months of browser-bug dataEver suspected those "Report Bug" tools in Web browsers leave you shouting into an abyss, your feedback discarded? An engineer at Mozilla, the maker of Firefox, has just confirmed that's actually been the case for months. Mark Smith explains that his misconfiguration of database led to the loss of three months of data about websites which users say Firefox doesn't display correctly, information Mozilla uses to "help prioritize fixes to the browser."The loss is especially ill timed, given the recent launch of Google's Chrome browser, which Google says uses the search engine's extensive index of the Web to test for display bugs. Smith is taking the error like a man: "I fucking did it and it was my fault and that's that." But he might want to update his recent post about optimizing database configurations for Web applications. Experience is the best teacher of all.
