I think it’s important to note that a lot of the statistics for browser usage appear to come from w3schools.com. They derive those statistics from their own user base, so while it’s an accurate representation of their own viewers, it really only serves as a benchmark for the rest of us!
I’m not sure there are any very broad surveys out there that would give a very accurate number in this regard, though I would love to see one! Whatever the case, it’s worth nothing that a site built primarily for developers will most likely yield higher percentages of viewers using browsers like Fx, Chrome, Opera, etc.
Neither the wikimedia stats, or the w3schools stats would provide a very reliable representation of all internet users. It would be expected that the wikimedia stats to be more consistent with the general population though considering that w3schools targets developers and designers (who are often more educated about browser choice).
“Not as popular as the competition” is not a weakness. Weakness by definition has to be a flaw or weak point. Popularity is neither of those.
There are so many mistakes on your site that it’s sad. Do your research and try again
