Same here, but for me it lags on all of my three, completely different PCs.... I think it started with the update to version 57...
All have W10 x64 1803 and 8GB RAM
- Ryzen 5 2600 + GTX 1050ti
- Core i3-6100U with integrated HD520
- Core i3-540 with integrated GPU.
It is not really freezing for me, more like lagging (but that depends on what you call freezing...)
I had to switch back to Chrome, which does not have this problem at all.
