When you visit certain large sites in Firefox or Safari, the browser may detect your visit and change its behavior. It could be as simple as lying about its identity, or it may totally change how it renders the page. But according to a post by [Den Odel], this isn’t a conspiracy between browsers and big Internet — rather, it is a byproduct of Chrome’s dominance.Here’s how it goes. Chrome puts out a new feature and everyone rushes to implement it on their site. Maybe the new code breaks other browsers. Maybe the other browser supports the feature, but the website doesn’t detect it correctly or is unaware. Maybe it just relies on some quirk of Chrome. Regardless, Firefox and Safari will change to match the site rather than mess up the user’s experience.If you want to check it out, Firefox will show you what it does and let you disable specific fixes if you visit the about:compat URL. For Safari, you’ll have to read code from a file named quirks. Bugzilla tracks the fixes for Firefox, if you want more details.Browsers are huge and complex so even niche browsers, today, usually use one of a handful of rendering engines. It seems that the question isn’t if a big company should control the way the web works. It is more a question of which one is currently dominating.
