I'm still pretty sure that the complete drop off of snowflake users has to do with Tor Browser crashing when configured to use the default snowflake bridge.
But, I did notice some other weird behaviour. The number of unrestricted snowflake proxies dropped off at around the same time (and the number of unknown proxies rose dramatically). This should not affect most users (I have been able to bootstrap Tor fully using snowflake with the same torrc configurations options that Tor Browser uses). However, it is weird. I'm not sure yet of the cause, and it could be a coincidence that these two events coincided.

Hi David,
I'm able to use snowflake on the command line, but not in Tor Browser. This seems to be due to this bug: https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/40282
I'm a bit surprised that it took so long for the issue to be reflected in snowflake statistics, I also hadn't run across it myself until I tried to change my Tor Browser config after reading this email. Philipp and I are talking with the browser and core tor developers about a fix. I'm a little surprised we are only finding out about this now. But, it seems to not be an issue with Snowflake itself.

I happened to look at the Snowflake bridge's bandwidth and user history page, and the counts are close to zero since yesterday. I haven't investigated it at all.
