Firefox reality browser - bad performance

We’ve build a scene out that using the 4.2.0-beta-6 engine, and we’ve noticed on firefox reality browser the performance is really bad. Has there been any updates in the engine to resolve this sort of thing? I ask as I need to engage an external party to deal with updates if I need to update to the latest version of the engine.


I’m afraid this has to be seen with Firefox directly ;(

oh wow, it’s a real shame. Chromium based browsers work really well.
