FPS Issue on Firefox using Physics

Get help using Construct 2

Hi scirra community;
I was not sure if this is a bug, so I decided to post it on here before proceeding, during some of my stress testing I found performance issue when using the Physics Behavior in Firefox 34.0.5 which does not impact Chrome [I did not test other browsers]. I tested this by creating a new project with a TileBackground and running it for a few minutes, then a few minutes later add the Physics behavior, run it and wait a until I saw the FPS start to drop. I did this by running it with the debug layout and monitoring the FPS dropping, this usually happen in about 5 minutes or so. please see picture below for illustration, is this an issue with firefox?

humbly

Hi,i just purchase C2 yesterday and i have the same problem,its running at 60fps for a while then the fps drop to 8-15 and doesnt come back,firefox memory usage also goes all over the place jumping roughly 40mb memory usage.
I also tried an empty project (to be sure if it was not my fault) and i had the same fps drop,no graphic no events. :?:
It happen between 1 to 5min after opening it on firefox 34.0.5
No issue under IE11.

(it seems to work fine on my side now, all i had to do is put the preview back on Localhost and did a 10min test without major fps drop)

@iSebz just to double check, so your not seeing any issues with Firefox anymore using physics?

I just tryed the ragdol example again but with wifi preview on my ip (instead of localhost) , after 36 seconds its went down to roughly 8-15 fps and my whole browser (firefox) was lagging.

No problem under InternetExplorer , 60fps the whole time.
