AMP FTS experiment

I think FTS means Full-Text Search in the context of SQLite. In the PR commit, you can see code such as https://github.com/mozilla/application-services/pull/6558/files#diff-fdb835ab6b6f5934bf19c2f0ce0a61eef17f3a2cfed5e2b3b220fab5728b2106R350-R353, which makes me believe AMP might stand for Good ol' Google's https://en.wikipedia.org/wiki/Accelerated_Mobile_Pages?

[rusty-snake]

"Accelerated Mobile Pages" or "Ampersand" are my most likely matches, but I need to check

[celenityy]

can someone tell me what AMP suggestions are?

AMP here is short for adMarketplace (1,2) - it’s just referring to Mozilla’s sponsored/ad suggestions.

[Thorin-Oakenpants]

or "Ampersand"

&&&&&&&&& lolz wut!

well, fuck that shit. I didn't think it related to Accelerated Mobile Pages (although Brave did something with that), but couldn't seem to find an actual explanation - thks @celenityy

This UI also landed in FF141 - not keen about autofill, maybe there's a pref for that

This UI also landed in FF141 - not keen about autofill, maybe there's a pref for that

There is:

user_pref("extensions.formautofill.creditCards.enabled", false);

pref("browser.ipProtection.enabled", false);

Advertisement prompt for Mozilla VPN. Behind limited nimbus rollout. Not relevant for AF.

pref("dom.webgpu.enabled", true); // prev: false
