I'm a day 1 Firefox user. I recently faced lots of changes in Google's apps like News or Google (Now) that forced me to use Chrome from within the app, against my will.
I read that I could deactivate Chrome to have taps on Google's apps open links in my Firefox as they used to. So I did and it worked. But sometimes there's that video that Firefox can't read but Chrome can so the solution was only half good.
Today I learned about Android System WebView. It's the component that allows Chrome to run in other apps, amongst other things I think. I decided to deactivate this one instead and everything seems as I want again.
But what are the consequences of this action in the long term? Are there side effects I should fear?
