So I am still using Linux Mint 18.3 and loving it.
I switched back to Google Chrome. Firefox does not download very fast and it glitches on some websites.
Thunderbird is still my email client. Rhythmbox is my music player. I am still using Audacity for my podcast, and WordPress for my blogs.
The only non-open source program I use is Paint Shop Pro 7. I use it in Linux using Wine.
Hoping for good things for Linux and Open Source in 2019.
