@srirambv It seems that on Linux, this is controlled via the LANGUAGE environment variable (see https://groups.google.com/a/chromium.org/forum/#!topic/chromium-dev/D6Eoeh0G9Y4 for the gory details).

When launching on Linux like this, I saw the expected settings in chrome://adblock:

LANGUAGE=fr_FR ./brave

Verified steps from Description reproduce on macOS. However, if I set my system language/region to French/France:

and close/relaunch Brave, I see that Regional Adblock is enabled:

@LaurenWags I think that's expected as @emerick mentioned that macOS and Linux relies on system level settings in #41 (comment) which I assume would require the browser to be restarted for the settings to take affect.

@bbondy does that sound correct? Seems like it's only affecting Linux in any case as @LaurenWags's screenshot shows that Regional Ad Block: Enabled after a browser restart.

[bbondy]

I think that's correct, were you expecting something different to happen @LaurenWags ?

[LaurenWags]

@bbondy nope, I'm good - @emerick responded with #41 (comment). Wanted to be sure I documented what I saw for historical purposes.

I think this issue is easily solvable on Linux as well. Here's what i did

1. Add language packs from system settings
2. Change Language from settings and restart
3. Launch Brave and load adblock page, shows regional ad block enabled
