STEPS TO REPRODUCE: 1) Ensure you have an old version of Flash. 2) Ensure you are running e10s. 3) Load https://www.mozilla.org/en-US/plugincheck/ 4) Observe the old version being listed. 5) Update Flash from https://get.adobe.com/flashplayer/ 6) Reload https://www.mozilla.org/en-US/plugincheck/ 7) Observe the old version is still being listed. 8) Open https://www.mozilla.org/en-US/plugincheck/ in a non-e10s window. 9) Observe the new version of Flash is now listed. 10) Reload https://www.mozilla.org/en-US/plugincheck/ in the e10s window. 11) Observe the new version of Flash is now listed. The incorrect thing here is step 7: it should list the new version of Flash. Mossop suspects that navigator.plugins.refresh may not do the right thing in a child process.

bz, did you restart the browser as part of the Flash update process? The process asks you to restart browser. Perhaps step 8 is acting like a restarted browser? I could not reproduce this if restarting the browser as instructed. Mac 10.11.2, Nightly 47.0a1, 20160209030347 - WFM Windows 7, Nightly 47.0a1, 20160208030244 - WFM Ubuntu 14.04.2, Nightly 47.0a1, 20160209030347 - WFM

I'm aware of that, but we don't actually need to do that in non-e10s, and restarting our browser is enough of a PITA that we shouldn't require it if we don't have to. > Perhaps step 8 is acting like a restarted browser? It's possible, but more likely it actually correctly rescans plugins....
QA Update: reference the attached and "ni" if I can provide further testing or assistance. I could reproduce original. (No browser restart and the plugin check page retained old info.) I then check about:addons and observed the info was displayed accurately. I returned to the plugin check page and then I was able to refresh and see the info correctly displayed.
no more testing needed, this looks to be triaged and confirmed correctly
And a duplicate. Although we should not be triaging this so low: it's a regression that could bite us pretty bad in the event of Flash 0-day updates. Not plugincheck in particular, but any site like youtube that does Flash version checks and alerts users to update.
