This has been confirmed by dozens of members of my website, all using Firefox, only started happening recently (after latest update I beleive), happens often.

My website contains an iframe, with an advertisement displayed in it. I use the onload event to track how long it's taking the ads to load. Sites that hang crash the browser. After removing the onload from the iframe tag all problems go away.

By hang I mean sites that have a high ping/latency and or have lots of content to load.

Reproducible: Sometimes

Steps to Reproduce:
1. Add onload="itloaded();" to iframe
2. Try to load the page with a hanging site in the iframe
Actual Results:  
crash

Expected Results:  
wait till page loads to run function itloaded()

Could you attach a testcase with the Add an attachment link on this page?

Comment 2

Sorry but I'm not sure what a "testcase" would be.

Attachment: Simple test

Tim,
does this problem still exist? If so, would you try to load the attached test in your browser?

(I couldn't come up with any other site that hangs - feel free to replace it with one of those you're using on your site if this makes a difference.)

WFM using mozilla-central Firefox on Mac.  I get "The connection has timed out" in the iframe, and no onload or onerror alerts.

Bjarne, is that what you saw?

Comment 5

[Bjarne (:bjarne)]

Yes, this is also what I see on Linux.

Comment 6

[Tyler Downer [He/Him]]

I see no issue, as there is no hanging site int he iframe :)

WFM -- we can't reproduce using Bjarne's guess-at-testcase, and Tim hasn't responded.
