No problem here with the latest 34.0 beta version.

Firefox uses too much memory (RAM) - How to fix This article describes how to make Firefox use less memory to make it run faster and prevent crashes.

So it seems to be something wrong with the report information. I tried with different profiles (default one, new one, ...) and different PCs, it wasn't a memory problem.

Now I tried at home with Firefox 34beta9 and it crashes again: https://crash-stats.mozilla.com/report/index/7dd2c3c5-3a01-4936-9efc-b191d2141119

I updated to Firefox 34beta10 and now it works :)
