HN users usually reply to these kind of posts with their first experience using the product being shared, I was just following a trend, in case someone happened to know what this kind of error means.<p>In particular, I saw &#x27;EFILESYSTEMERROR&#x27; and thought maybe I set some Firefox preference too strict, and some of you could be familiar with the error.<p>But you are right, the best way to get this fixed&#x2F;understood is probably by contacting the devs&#x2F;support for the product.
