How do you tell "anti-Mozilla troll" from a genuinely dissapointed user? I'm currently on FF ESR, once my favorite extentsions stop working there I might as well switch the browser completely, since my UX will be completely reset just as it would be with a entirely different browser.

I'm not saying I will switch to something else (other browsers seem equally unusable to me as FF57 is currently), but I will certainly try all the options to find out if something else isn't at least marginally better than FF57.

I have been using Firefox for about 5 years, I'm still using it and despite that I'm anti-Mozilla. The browser performance has always been fine to me and 57 doesn't look particularly "faster" as they are advertising it.

I'm one of the dozen people that care about a browser being user configurable and not doing any analytics, telemetry, experiments,... . Mozilla has lately been working exactly against this. I have about 80KB of patch files just to remove all the crap Mozilla managed to stuff into an otherwise perfect browser like: advertisements, telemetry, more data sharing, geolocation using google servers, a social network and proprietary binary blobs for service integration.

When I build a clean version of Firefox then I'm happy too.
