Hi, I just noticed, that updating of a dynamic texture drops the framerate in firefox browser (122) to 20fps on my notebook, while chrome stays at 60fps. Here is a simple playground: > **[Babylon.js Playground](https://playground.babylonjs.com/#5ZCGRM%234896)** > > Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes If you do not see any difference, please increase the resolution. Is there any way babylon could improve the performance on firefox? Here a screenshot of firefox profiler with preset “Graphics” - unfortunately in german: ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/0/c/0c169718da1608c4a77022434cece0ea29538529.jpeg) Maybe related?

Kind regards! ---

Yes, I can affirm this is way slower on Firefox, very interesting! I always thought Firefox was just slow, but this might explain why, my game uses a lot of dynamic textures… Thanks for bringing this up! (edit: for me this PG is capped on chrome at 144 fps and 25 fps on FF!) ---

I get the same result. I tried a number of things (change the `premultipliedAlpha` value when creating the engine, change the texture format / the invertY value, …), but nothing worked. I don’t get any error/warning messages in the console, so it’s hard to know what the problem is… ---

Could you raise the issue with Mozilla, it definitely looks like they broke smthg ? ---

Replied in the mentioned issue on bugzilla. Hope it is the right place. 8 year old ticket 😕 ---

not sure if this is true for Firefox, but for Chrome you can download all old versions so you can check if a version from 1-2 years ago already has this issue. If it’s a newer problem it is much easier to report. Me, I just recommend all my players to not use Firefox for games 😕 (and on my landing page I recommend Chrome, sad as this is)
