Description

2 years ago
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0
Build ID: 20160623154057

Steps to reproduce:

Attempted to View Source on a message consisting mostly of a 15MB GIF


Actual results:

TB went totally unresponsive (Windows "dimmed out", title bars show "Not Responding") for about 5 minutes.


Expected results:

TB should not have completely locked up, and/or should have been able to View Source with less delay.
