Here are some other HTTPS-enabled search engines to test. If I am not mistaken all have been mentioned on HN in the past.

But hey this does not really matter anymore as after over 15 years of supporting mozilla I have had enough of its utter nonsense and have now left firefox with the firm intent to never return and have stopped supporting anything mozilla while actively hoping it will fail and disappear, the sooner, the better.
Way too much disdain for the people using firefox, too much discrepancy between the marketing and the actual thing. Alienating long time supporter one by one is probably not the smartest strategy but hey what do I know, mozilla is making hundred more millions with a fraction of the past user base so they're probably successful by their own metrics.
Sometimes, I've been told the setup I was using wasn't supported, but they'd accept a patch if I was willing to invest some effort in it. I did once, and the patch was indeed accepted.
Obviously, Mozilla cannot support every obscure platform, but then again neither does Chrome. I don't think your expectation match reality if you think that's the case.
My experience has been, rather, that Mozilla has had one of the most fantastically responsive bug filing systems. Actually getting bugs fixed in a timely manner is a different question, but that's independent of bug tracking systems.
