This isn't much about the non-mainstream browsers.
I'm currently using Cent Browser Bonbon browser, sleipnir browser, slimjet, seamonkey, palemoon, mint, phoebe, supermium and sware iron.
In this list, only Cent Browser, Seamonkey has issues relating to cloudfare, while supermium and sware iron, also chromium derrivatives, doesn't face this issue.
So after a bit of researching, this could very well be the state of how outdated a browser is. Maybe some changes were made in the newer updates for all browsers, while Cent, for example, is so outdated it lacks that feature.
To be more specific, I believe that IceCat, Basilisk, palemoon and Seamonkey runs on roughly the same engine, an oudated version of firefox. While Cent runs on an outdated version of chrome
