I'm confused. Did bug 715768 cause this bug, or fix it? If it fixed this bug, then this bug would not be fixed on FF15, where Azure-Content is disabled.

Comment 4

[Alice0775 White]

Yes, Azure-Content is disabled in beta by Bug 769993.
However, that beta does not release yet. so I cannot check.

OK, thanks.

The problem came back. I can reproduce the problem in Firefox 15_0b4.

This affected Firefox14.0 and Firefox15Beta, because Azure-Content is disabled by default.
And, This not affected Aurora16.0a2 and Nightly17.0a1.

Roc can you advise on what our options are at this point for FF15?  We've got one more beta (going to build tomorrow).

Comment 9

[Robert O'Callahan (:roc) (email my personal email if necessary)]

I don't understand this bug. Comment #0 says it's supposed to have been caused by turning on Azure-content. But Azure-content was disabled in FF15, so in comments #4 and #5 I thought we agreed it should be fixed in FF15 and we just hadn't verified that yet. Yet in comment #7 Alice says it affects FF14 and FF15 after all.

(I don't see any problem on that page in Nightly, although my laptop is fast.)

Thanks! I knew I must have misunderstood you, since you don't seem to ever make mistakes :-).

Then, since this is already a bug in FF14, I say wontfix this for FF15.

Thanks everyone, wontfixing.

Comment 13

[Virtual_ManPL [:Virtual] 🇵🇱 - (please needinfo? me - so I will see your comment/reply/question/etc.)]

Can you still reproduce the issue with latest version with clean new fresh profile without any addons and plugins?

[Virtual_ManPL [:Virtual] 🇵🇱 - (please needinfo? me - so I will see your comment/reply/question/etc.)]

We can probably mark it as WONFIX per Comment 10.

Comment 15
