I do not use Brave Browser for convenience. I use Brave Browser for its Privacy & Security. I liken the browser to a special version of a chess board:
Brave Browser has 3 rows of Pawns, and 8 Knights. Google Chrome and MSFT Edge have the traditional chess boards.
Regarding Brave Shields:
I have more success, with:
- Brave Shields UP
- Either Allow All Cookies or Block 3rd Party Cookies, but NOT Blocking All Cookies
- Allowing JavaScripts from specific sources, but NOT Allowing All JavaScripts
- Trackers & Ads treatment: Aggressive (at first), and then incrementally relaxing that setting
- Fingerprinting (aka footprinting) blocking: Strict (at first), and then incrementally relaxing that setting
I almost NEVER use:
- All of Brave Shields UP
- All of Brave Shields DOWN
If a Brave Browser user enables Shields DOWN, then the browser is effectively using the traditional chess board.
If a Brave Browser user leaves Shields UP and carefully/incrementally adjusts the settings, then the browser uses its special chess board.
The other side of the chess board, is the website and its servers.
The objective is, to only allow the removal of the few chess board pieces that provide enough avenues for the website servers, to do enough of their jobs that provide enough of what Brave Browser needs to render the webpage(s).
Incremental / subtle changes in Brave Shields settings, lead to incremental / subtle differences in website payloads that are sent to the browser.
Thereby, incremental / subtle changes in Brave Shields settings have some control over what the website sends and how the Internet browser reacts.
I use Brave Shields as a firewall: Shields UP being DENY ALL - but ALLOW some traffic: the necessary traffic.
