Mozilla launched an experiment final year to see if model quantity 100 would have an effect on websites, and it simply released a blog with the outcomes. It did have an effect on a small variety of websites (some very massive ones, although) that could not parse a user-agent string containing a three-digit quantity. Notable ones nonetheless affected included HBO Go, Bethesda and Yahoo, in accordance with a tracking site. The bugs embody “browser not supported” messages, website rendering points, parsing failures, 403 errors and so on.

How might such a foolish factor be occurring? “Without a single specification to follow, different browsers have different formats for the User-Agent string, and site-specific User-Agent parsing,” Mozilla defined within the weblog. “It’s possible that some parsing libraries may have hard-coded assumptions or bugs that don’t take into account three-digit major version numbers.” 

Luckily, builders for each browsers have a plan.

The browsers are set to reach on March twenty ninth and May third for Chrome and Firefox respectively — hopefully like Y2K, it will be a lot ado about nothing..
