User Agent: Mozilla/5.0 (Windows NT 5.1; rv:15.0) Gecko/15.0 Firefox/15.0a1
Build ID: 20120511030513

Steps to reproduce:

I'm using Nightly. While I was looking Facebook photos, this script gave error. Not one time.

Actual results:

This script is giving error "https://s-static.ak.fbcdn.net/rsrc.php/v2/yr/r/NbUH3T8_mCD.js:49"

Expected results:

This script should be work.
Is this only an issue with this build or does this also happen with Firefox12 as example ?
Can you try it in the Firefox safemode ?

We need steps to reproduce, "looking Facebook photos" is not useable.

I realized this isn't only existing on Facebook photos. It's existing anytime you roam at Facebook. I'll try it in SafeMode.

Can it be Adblock Plus' issue?

Not entirely sure why this was moved to the Addon Builder component. This doesn't look like it has anything to do with Builder...

I'm just change it. I'm researching which part of component so it isn't true I know.

Unlikely. Most likely cause of this is a script that assumes that all web requests will load successfully and that goes into an endless loop if this doesn't happen for some reason.

For reference: line 49 of NbUH3T8_mCD.js refers to the ServerJS API (all of it thanks to obfuscation). Obfuscation makes it hard to tell what this piece of code does and why it hangs up.
Duplicate of this bug: 765117
Tried reproducing on vista, with no luck after about 15 minutes.
Changing the status to new due to duplicate bug and 2 more reports in Nightly testers mailing list.

Any chance this is related to bug 690229?

I get this fairly regularly on Nightly and release while using Facebook when the tab has been open for a few hours and I've been using it for photo's and chatting. Closing the facebook tab and reopening clears the issue until another few hours pass.
