[HowTo] Google Chrome Tweaks for 86.0.4240.75 (or newer) | 20201007

Difficulty: ★☆☆☆☆

This is my recommendation for best experience with Google Chrome. Feel free debate about options.

For some reason --enable-features and --disable-features are not to be applied properly from chrome-flags.conf file. Then enable it properly flags in chrome://flags page. See URLs below.

Create FILE ~/.config/chrome-flags.conf

nano ~/.config/chrome-flags.conf

with SINGLE LINE CMD:

--flag-switches-begin --force-dark-mode --high-dpi-support=1 --force-device-scale-factor=1.2 --ignore-gpu-blacklist --enable-smooth-scrolling --flag-switches-end

Disable Media key controls applet and keyboard binding handling. Disable QUIC protocol against connections issues

SET DISABLED IN

chrome://flags/#enable-quic

See: How Google's QUIC Protocol Impacts Network Security and Reporting

SET ENABLED IN

chrome://flags/#tab-groups
chrome://flags/#privacy-settings-redesign
chrome://flags/#omnibox-context-menu-show-full-urls

SET ENABLED (mark as actively dangerous ) IN

chrome://flags/#enable-mark-http-as

Perhaps you should mention what the flags do and why you’re using them. There’s no one-size-fits-all approach to customization.

Also, Chrome flags are experimental and may disappear tomorrow. This tutorial will be made obsolete relatively soon unless you come back to make changes as appropriate.
