Crewdroog: Is this happening to anyone else right now? If i have chat open on another tab, it keeps causing firefox to crash. 
  Vythonaut: Just noticed the crashes too. I'm logged in from another laptop (Win8.1, Firefox 40.0.3, ABP 2.6.10, NoScript 2.6.9.36, Greasemonkey 3.3) and already had two crashes the first 5 minutes i've used the chat.  
 From my laptop (Linux - Peppermint OS, Pale Moon latest version, ABP 2.6.10, NoScript 2.6.9.36, Greasemonkey 3.3) never had a single crash or anything. 
  Hmmm... I have no problems with chat on Ubuntu 14.04 LTS and FF 40.0.3 (opened 10 chat tabs, wrote some long messages, left them running for 30 minutes). I will test it on Windows and OSX. This is very weird and I don't know what could be the cause for now - it should be possible to debug if we reproduce the crash and locally revert changes that were made on and before 25.08. Please be patient. :)  
 If you have any problems with chat, just ping me on chat... :D Just kidding.
