QUESTION
I'm trying to load a texture into a 2d plane like demonstrated on this post How to draw 2D image with TWGL (WebGL helper Library).
It works fine when including the script tag like so
But when when trying to do so with the exact same code with es6 modules I get the following error [.WebGL-0x7f90b084f000]RENDER WARNING: Render count or primcount is 0.
Using gulp and browserify like so

QUESTION
I am currently developing an image processing tool for a webapplication. I need to take to png-images of the same size and combine them pixel by pixel. So far, I have set up a prototype (very much inspired by the tutorials on webglfundamentals.org) that takes two images and just multiplies their pixels. I am using the twgl-helper library for webgl from http://twgljs.org/ . (Which I could unfortunately not put into the fiddle).
I have the following question: Can anyone explain or give hints, why Firefox 78 is so much slower in this than a recent Chrome? FF averages about 34ms per render (complete refresh and wipe cash between samples) while Chrome averages 0.27ms per render. This is two orders of magnitude of a difference which i just can't explain. I have tried webgl2, it is slightly faster for both but keeps the insane difference between the two.
If I need to provide more info, pls let me know, I will be back in the office on thursday. Thank you for your support and ideas.

Answered 2020-Jul-11 at 16:55It is not really possible to count on browsers having similar performance. There are plenty of tests where one browser is 2x to 40x faster than another.
In this particular case I don't know why modern Firefox is slower than Chrome. Chrome is multi-process (I thought Firefox was too at this point but maybe not) so in Chrome the timing is only timing how long it takes to insert commands into a command buffer to talk from the process that's running webpage to the separate process that talks to the GPU. It's not timing how long it actually takes to run those commands which run in parallel to the webpage.
If I add this after your draw call
