This might just be another instance of bug 403199.

Probably just a dupe of bug 403199, so not blocking

Was this (partially) solved by bug 403199 check-in ?

Tested several times on: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:29.0) Gecko/20100101 Firefox/29.0 (20140121172905) Firefox leaks nsSimpleNestedURI but it doesn't have to have any certain tabs open, nor to be at the first start with FlashGot. It's enough to have FlashGot installed and restart Firefox. Bloat log: 803 nsSimpleNestedURI 136 2720 23 20 ( 8.19 +/- 5.01) 2384 199 (298765388805976576.00 +/- 0.00)
