Oof, yeah IRC is awful and sadly we're forced to use some things that still use IRC to communicate and we're not really sure why. There does seem to be a derth of users that have moved with the times in leadership positions of important projects.
We have seen it recently with some things we use and we hope it strongly forces them to consider being wrong or that it blows up in their faces. Because yeah, we agree if you're not moving with the times you will hemorage contributors and then you'll only be left with the 'old guard' or worse people (such as fascists not that two aren't the same many time, heh).
Also, Mozilla is just a really poorly run company to begin with and needs some serious restructuring and to stop doing things that serves only itself and not its users. If it genuinely cared about its users and allowed direct donations to firefox perhaps folks would have fewer problems with it.
Sure, we are happy to help!
They mean that stories are hidden away in a tab rather than up at the top which would be clearly visible at all times, like other messaging apps do it.
