There's a steady trickle of these.

Almost all of them are on Android, but I found one that was on Windows: bp-52007ac8-6363-4fb8-b848-0b9ba0231004

ni? farre to make you aware of these if you haven't seen them already.

Comment 4

[Liz Henry (:lizzard) (relman/hg->git project)]

Looks like a signature that has been very low volume since 125, but had a spike in Nightly (Desktop) 129 in build 20240625093602

Comment 5

[Randell Jesup [:jesup] (needinfo me)]

appears to be spiking again, though still low volume in total

Comment 6

[Valentin Gosu [:valentin] (he/him)]

Andreas, there are some recent no-Android assertions. Do you need some help diagnosing them?
