FF42a1 unsafe CPOW usage

Post by therube » Wed Jul 01, 2015 3:28 pm

FF42a1

Error Console is spitting (spamming) out:
> unsafe CPOW usage

various places/lines:
> view-source:jar:file:///.../extensions/%7B19503e42-ca3c-4c27-b1e2-9cdb2170ee34%7D.xpi!/components/flashgotService.js
...

Ah well, suffice it to say that it happens in MediaSniffer.js too.

(No clue how that foreakin' 'Browser Console' works. Seems as if I should be able to copy the affected file name/line, but I'll be if I can figure it out.)


I'm seeing this while logged into http://www.amazon.co.uk/musiclibrary.
Don't know offhand if it generally happens, everywhere, or at other particular sites?


Oh, I also have not checked any other FF (or SeaMonkey) versions to see if the same happens elsewhere.


(Also, separately, saw a "FlashGot might be making Nightly run slowly, but that might be "normal"? And in any case, I had just finished purposely "crashing" FF 42, e10.)

This is all relatively "normal" and "expected" during the transition to E10s, which will take some other weeks at least.
"Unsafe" here just means that the observed IPC pattern might (but in this case doesn't, actually) cause the browser to hang.
