If you’ve got been to Mozilla AMO lately, the foremost and official repository for Firefox add-ons and themes, you’ll have seen that the “customers” count of extensions that you simply checked on the market has dropped. Take the common content material blocker uBlock Origin for instance. The extension’s present count is three.94 million customers in accordance with Mozilla AMO; some days in the past, the count was 5.5 million customers.
Mozilla revealed a blog post on the official Mozilla Add-ons weblog that highlights why there is a drop throughout the board on Mozilla AMO with regard to the variety of customers.
Mozilla worker Jorge Villalobos reveals there that Mozilla revamped the statistics that it makes obtainable to add-on builders.
The outdated system used stats aggregated from add-on replace logs. Firefox checks Mozilla AMO day by day for updates for put in extensions which might be hosted on the web site. The aggregated knowledge was offered to builders and a few of the data is also accessed publicly; builders would get normal details about customers akin to adoption or demographics.
He notes that the system was “expensive to run” and that knowledge glitches occurred infrequently.
The new system drops the use of the day by day add-on replace verify and depend on Telemetry knowledge as a substitute. The knowledge is aggregated and no personally identifiable user knowledge is shared with builders similar to earlier than in accordance with Mozilla.
The drop in customers is attributable to the swap to the new system. It seems that, in the case of uBlock Origin, about 1.6 million customers of the add-on have Telemetry knowledge disabled in Firefox. Privacy, safety and superior extensions will doubtless see a bigger drop in customers than different extensions as customers of those kind of extensions usually tend to flip off Telemetry.
One of the advantages of utilizing Telemetry knowledge is that knowledge will be proven for add-ons that aren’t listed on AMO. Developers will get entry to all add-on utilization stats no matter the place the add-on is hosted or the way it is distributed. Mozilla plans so as to add utilization by nation as effectively in the future.
Two options that have been obtainable beforehand will not be obtainable anymore, nonetheless. Developers will not see a breakdown of utilization by add-on standing anymore, and the means to show the statistics dashboard publicly is now not obtainable.
Villalobos notes that whereas the numbers are “usually” decrease, they do “observe very effectively with the replace numbers by way of change by time and the way languages, platforms, variations, and many others., examine with each other”.
