Yeah this is so shame. :awww:
For me is a fantastic broswer. Great performance (speed, smooth, ram), great features, tampermonkey runs all scripts. I was with Firefox cause I had/am having a huge problem using Safari. Safari and Opera are the best out there for sure, but damn. Is so bad that you need to open other broswer to check a (youtube) video or twitter stuff. And then you forgot to go back to opera and continue there.... I am on beta for first time since Sierra and I am sending feedback reports. Likely they replied back to me twice to and asked me to take sysdiagnose files while my system hang, and is possible to grab it, so I am sending as they asked. Hopefully they will fix it, but I can't hold my breathe. Firefox became so shity last years, have hard times browsing sites like abduzeedo and in general sites like this, became so slow. I really don't want to mess with Chrome.
So, I guess from your answer @avl that there's no reason for you to try a different way or company to pay for the (expensive) license. I understand. Even if I am the only one with this Safari problem (that is impossible) and devs are having hard time to fix it, put it to archive for "later" because I own a 2010 model and want to focus to newer machines, I understand. But that's really really bad for us lol
