I have been testing Windows 10 on an HP Stream 13 using the Edge browser for the last week. I have seen high memory use and 1 browser crash. In the previous 2 months using Firefox on the same device under Windows 8.1 I never suffered one browser crash. This link shows that Edge is even more memory hungry than Chrome which is already a memory hog.
In conclusion we will use Firefox as the preferred browser on HP Stream devices. Ideally this would be distributed with the Adblock plugin which dramatically increase performance on web pages that contain advertising.
