Firefox "Studies" system brief technical investigation: Normandy, recipes, and what's going on behind the scenes (no drama)
I'm highly interested in https://bugzilla.mozilla.org/show_bug.cgi?id=1587357 , flipping on the new Rust bookmark sync engine in stable - I've had out-of-order syncs with the old engine, which the new one should fix.
So, by viewing a graphical browser of Shield studies here: https://www.jeffersonscher.com/sumo/shield.php
I narrowed it down (check the "Surveys" box so all are enabled). Or, better yet, with Firefox's JSON viewer, you can directly browse the 1.26 MB JSON blob at https://www.jeffersonscher.com/sumo/studies_json.php
With this, I found the experiment I wanted by filtering on
services.sync.bookmarks.buffer.enabled. I can tell that 25% of folks currently have it thanks to the
"(normandy.channel in [\"release\"]) && ((normandy.version>=\"70\"&&normandy.version<\"71\")) && ([\"new-sync-70\",normandy.userId]|bucketSample(0,250,1000))"
bucketSample(0, 250, 1000), creating 1000 buckets with 250 of them selected.
Which is documented here, along with the rest of Normandy on one of #Mozilla's websites: https://mozilla.github.io/normandy/user/filters.html
…I could just flip the pref manually in
about:config, but I feel like I should wait for the rollout for some reason.
