AugmentedSteam VS proton-chrome-extension

Actually using CHROME + https://augmentedsteam.com/ is the BEST experience that you can ever obtain in your Lifetime at the moment because https://developer.valvesoftware.com/wiki/Chromium_Embedded_Framework is long time proven to be "Broken" against other websites, Steam UI overhaul removed CEF UI for Electron UI that even Back button is now broken from time to time, there's NO Ad blocking and other extensions on Steam Client, in short you're utterly clueless of what you're suggesting.

This is why I use the store from my browser with the augmented steam addon.

I use it with their browser plugin Augmented Steam: https://augmentedsteam.com/ (you can use with Chrome, Firefox, Edge)

・Augmented Steam：https://augmentedsteam.com/

Seriously. I've saved so much money thanks to ITAD (and, by extension, Augmented Steam) since Steam is not often the site offering the lowest price. Even now with the Summer Sale going on, most of the games I'm interested in are cheaper on Green Man Gaming, GameBillet, and Fanatical. Anyone who isn't using ITAD to track sales is a bit of a fool.

And you can check this either by using SteamDB like https://steamdb.info/app/546560/ to learn the percentage difference after setting your currency and checking the other currency or simply install https://augmentedsteam.com/ that does the same thing but more pretty.

The extension can be found here on the chrome web store or here on github
