[Bug 1650412] [NEW] Firefox fails to display a webpage properly, prints out a stack trace instead

[Ceridwen]

Public bug reported:

If I try to visit a game's page on terra.snellman.net, for instance
http://terra.snellman.net/game/4pLeague_S16_D1L1_G3, most of the page
text, after the map, is replaced by a red block containing the following
text:

TypeError: ERROR.captureStackTrace is not a function
getStackTrace at http://terra.snellman.net/game/4pLeague_S16_D1L1_G3:81:7 getOriginatingScriptUrl at http://terra.snellman.net/game/4pLeague_S16_D1L1_G3:96:19 trapInstanceMethod/item.obj[item.propName]</<@http://terra.snellman.net/game/4pLeague_S16_D1L1_G3:147:28 drawText at http://terra.snellman.net/stc/game.js?tag=81867ef83de6136d15ba9f0a28c6110511fc9cd7:29:5 drawCults at http://terra.snellman.net/stc/game.js?tag=81867ef83de6136d15ba9f0a28c6110511fc9cd7:459:17 draw at http://terra.snellman.net/stc/game.js?tag=81867ef83de6136d15ba9f0a28c6110511fc9cd7:3800:5 previewOrSave/<.onSuccess at http://terra.snellman.net/stc/faction.js?tag=9619f6a626a064d11830eb0c725c71b7a9ac7416:113:21 Ajax.Request<.respondToReadyState at http://terra.snellman.net/stc/prototype-1.7.1.js:1801:10 Ajax.Request<.onStateChange at http://terra.snellman.net/stc/prototype-1.7.1.js:1746:7
