Works fine. I installed it to open books in PDF format and use the Read Aloud extension to listen to them but it seemed to stop reading frequently. Ultimately I ended up going with Brave Browser for listening to PDFs and hardened Firefox for daily browsing. Chromium works as it should though and it's the default browser for CalyxOS so I can only assume it is a solid browser. :)
I installed it together with chromium. But some YouTube videos didn't play. Therefore I uninstalled chromium-chromedriver and then these YouTube videos played again.
Time to plug the Google Chrome and its extension
