> Firefox had 30% market share in 2010, I would hardly call that "niche", especially for a browser that didn't come bundled with your operating system or have the marketing power of the world's default search engine. In 2010 Firefox 3.5 had a estimated global market share of 15-20%. BTW nobody thought any of the stats were accurate at the time as they were easily skewed. Some counters would report 30%, but it was an estimate and not a reliable one. On the sites I was building, which were mostly travel sites, e-commerce and later gambling. Firefox was maybe 5-10%. I am also no in the US. I just didn't see anything like what was reported in site stats for the things I was working on. Later on it was IE and Chrome and Firefox was still at maybe 10%. I really cared about compatibility and web standards at the time and made every effort to make sure that the sites work. So I knew it wasn't a "the site doesn't work in this browser". > It also had an outsized impact on the web because it was a popular with developers for doing web development. So people that used the net heavily used Firefox and people that didn't tended to use IE. So on some sites Firefox usage would be far higher than it would otherwise be. e.g. People using IE might only use the internet for online shopping, checking mails, so visiting an online shop, booking a flight etc. Whereas many Firefox users would be using Social media, Blogs, Forums or YouTube more heavily. So you will see two completely different pictures depending on what your site's audience would be. That is why the statistics can be misleading.
