#WebGL

Research

As more users visit this site and opt into helping Camoufox's WebGL research, I will have a more solid profile of each GPU's parameters, supported extensions, context attributes, & shader precision formats.

#Demo site

This repository includes a demo site that prints your browser's WebGL parameters. You can use this site to generate WebGL fingerprints for Camoufox from other devices.

#Properties

Camoufox supports spoofing WebGL parameters, supported extensions, context attributes, and shader precision formats.

Warning

Do NOT randomly assign values to these properties. WAFs hash your WebGL fingerprint and compare it against a dataset. Randomly assigning values will lead to detection as an unknown device.

Property	Description	Example
`webGl:renderer`	Spoofs the name of the unmasked WebGL renderer.	`"NVIDIA GeForce GTX 980, or similar"`
`webGl:vendor`	Spoofs the name of the unmasked WebGL vendor.	`"NVIDIA Corporation"`
`webGl:supportedExtensions`	An array of supported WebGL extensions (full list).	`["ANGLE_instanced_arrays", "EXT_color_buffer_float", "EXT_disjoint_timer_query", ...]`
`webGl2:supportedExtensions`	The same as `webGl:supportedExtensions`, but for WebGL2.	`["ANGLE_instanced_arrays", "EXT_color_buffer_float", "EXT_disjoint_timer_query", ...]`
`webGl:contextAttributes`	A dictionary of WebGL context attributes.	`{"alpha": true, "antialias": true, "depth": true, ...}`
`webGl2:contextAttributes`	The same as `webGl:contextAttributes`, but for WebGL2.	`{"alpha": true, "antialias": true, "depth": true, ...}`
`webGl:parameters`	A dictionary of WebGL parameters. Keys must be GL enums, and values are the values to spoof them as.	`{"2849": 1, "2884": false, "2928": [0, 1], ...}`
`webGl2:parameters`	The same as `webGl:parameters`, but for WebGL2.	`{"2849": 1, "2884": false, "2928": [0, 1], ...}`
`webGl:parameters:blockIfNotDefined`	If set to `true`, only the parameters in `webGl:parameters` will be allowed. Can be dangerous if not used correctly.	`true`/`false`
`webGl2:parameters:blockIfNotDefined`	If set to `true`, only the parameters in `webGl2:parameters` will be allowed. Can be dangerous if not used correctly.	`true`/`false`
`webGl:shaderPrecisionFormats`	A dictionary of WebGL shader precision formats. Keys are formatted as `"<shaderType>,<precisionType>"`.	`{"35633,36336": {"rangeMin": 127, "rangeMax": 127, "precision": 23}, ...}`
`webGl2:shaderPrecisionFormats`	The same as `webGL:shaderPrecisionFormats`, but for WebGL2.	`{"35633,36336": {"rangeMin": 127, "rangeMax": 127, "precision": 23}, ...}`
`webGl:shaderPrecisionFormats:blockIfNotDefined`	If set to `true`, only the shader percisions in `webGl:shaderPrecisionFormats` will be allowed.	`true`/`false`
`webGl2:shaderPrecisionFormats:blockIfNotDefined`	If set to `true`, only the shader percisions in `webGl2:shaderPrecisionFormats` will be allowed.	`true`/`false`
