Details

Looking at metrics.services.mozilla.com I see elevated crash rates for the Russia geographic region: 226 crashes per 1000 profiles for all regions 469 crashes per 1000 profiles for Russia In addition, crash rates in Russia have trended up from ~375 in September while overall crash rates have been dropping.

It looks like there's a larger incidence of Flash crashes with the Russian locale: https://mozilla.github.io/stab-crashes/scomp.html?common=product%3DFirefox%26release_channel%3Drelease&p1=useragent_locale%3D%21ru&p2=useragent_locale%3Dru If you look at the correlations for "npswf32_24_0_0_186.dll%400x3da24d" (https://crash-stats.mozilla.com/signature/?product=Firefox&release_channel=release&signature=npswf32_24_0_0_186.dll%400x3da24d#correlations): (42.44% in signature vs 09.67% overall) useragent_locale = ru (41.71% in signature vs 09.43% overall) e10s_cohort = temp-disqualified-ru (12.26% in signature vs 38.27% overall) dom_ipc_enabled = 1 Is it possible Flash crashes are more likely without e10s and so, given that we disable e10s for the Russian locale, it is particularly affected?
I spent my entire day on a ru Nightly 54.0a1 locale (with e10s enabled and disabled) using a VPN from Russia, Saint Petersburg and focused on flash sites. I didn't encountered any crash. Is there a way I can help with the investigation of this bug. Would you like me to focus on certain areas?
Marco, Is there something we can do here or should we just close it as Resolved Incomplete? Thanks!

FWIW, crash rates in russia started coming down the last week of January. Looks like a 30% drop in crashes. Not sure what happened to cause that.
There are a couple of Flash crashes which are almost Russian only: https://crash-stats.mozilla.com/signature/?product=Firefox&release_channel=release&signature=RtlpLowFragHeapFree%20%7C%20RtlFreeHeap%20%7C%20HeapFree%20%7C%20F1901407414_________________________#correlations https://crash-stats.mozilla.com/signature/?product=Firefox&release_channel=release&signature=RtlSizeHeap%20%7C%20F_1079268936____________________________________________________#correlations (In reply to Ben Kelly [not reviewing due to deadline][:bkelly] from comment #7) > FWIW, crash rates in russia started coming down the last week of January. > Looks like a 30% drop in crashes. Not sure what happened to cause that. This would support my hypothesis in comment 4, as the last week of January is when we released 51, which unblocked e10s for Russian users (bug 1304874).

Marco, data is helpful but we really need somebody to make a decision. If this bug is to remain open, what component/team should it belong to? Otherwise can we resolve it WFM or INCOMPLETE or something?

OK, I think we can close this as WORKSFORME now, since the Russian crash rates are back to normal. We can file new bugs for the two Flash crashes, if needed.
