On PC's there is a difference between browsers
On pc, playing in a browser, i encounter continuously bugs (freezes needing hard reset) in Chrome.
The game is much more stable in Firefox. (both latest version and in windows 10 64bit).
Do you notice a difference in reliability between Firefox and the Steam client?
I switched from Chrome to the Steam client for exactly the reasons that you talk about. I assumed that the reliability issues would be systematic across browsers, but it sounds like it may be limited to just specific browsers.
I am pretty sure Chrome is still listed with known issues. I stick to Firefox on macOS and look forward to trying Steam on Windows.
