That's great to know that FF-ESR 45.90 is more secure than the regular FF 49.0X.īrummelchen wrote:there exist NO current firefox build for XP, neither with´or with or without SSE2. In the meantime, I've also acquired the latest ESR 60.X version for other systems, though normally I am a Seamonkey user and am only using Firefox as a back up browser. So in this case, it was necessary to select the latest available non-SSE2 required ESR version, which was indeed ESR 45.9, which is what I've got installed now. Only ESRs will comply with that configuration switch value. Yes, the SSE2 compatibility issue was the constraint at hand hence the pre-version-49.0 requirement, but since then I've also discovered that ESRs also allows unverified plug ins / extensions to be installed without being blocked, despite the fact that in the regular Firefox consumer releases, it ignores the ABOUT:CONFIG parameters that disables the plug in signatures requirements. The ESR versions were based on 10.0, 17.0, 24.0, 31.0, 38.0, 45.0, 52.0 and now 60.0 The only reason why you could not use Firefox 49.0 or later versions on Windows is because the CPU you have does not support SSE2. I will try upgrading the graphic driver to the latest version and try again.James wrote:There was no ESR based on 48.0. The same blacklisting happens in Firefox portable 50.1.0 where the Cesium map has no issues.

I opened Firefox 52.0.2 about:support and the page is listing Hardware H264 Decoding with the following information: No D3D9 blacklisted with DLL atium64.dll (9.14.10.996).

Would this other app working fine would rule out a blacklisting of the driver? Tested using another app based in webgl and the app has no issues. The performance issue is happening in all the computers with the following OS and graphic card: Both show different errors but the errors in Firefox 50.1.0 are not affecting performance like it does for the errors in 52.0.2. I also attached the console errors when using Firefox 52.0.2 and 50.1.0. FPS in firefox 52.0.2 is 9, while in Firefox version 50.1.0 the fps has an acceptable 34 to 40. The report is identical when using Firefox 50.1.0 portable. Attached you can see the webgl report when using Firefox 52.0.2.
