Nono, you expect people to use the most used versions of the tools. Firefox has such a low usage that using the “Firefox version” of the “browser” tool can be interpreted as using an “outdated tool”. You clearly don’t, and neither do I, but some people put the line in a different place than you do and I don’t think it’s fair to say it’s their fault for it.

Sure, for webpages where the objective is to have advanced functionality I do get it, but for news/blog posts, documentation, government pages that should be as robust as possible… There are paces where accessibility of “outdated” tools must be considered.
