How to install driver for AMD video card in xubuntu 14.04?

Question

linux

I ran into a situation where the transition from xubuntu back to windows7 is at stake. Already goosebumps.
I need hardware acceleration for Canvas WebGL for learning, but as it turns out,
ubuntu 14.04 is not supported.
I got into Google and found the article Proprietary driver for AMD video cards and installed it, as evidenced by the picture below -

But everything remains the same, I look in opera: gpu and it says -

Graphics Feature Status
Canvas: Software only, hardware acceleration unavailable
Flash: Hardware accelerated
Flash Stage3D: Software only, hardware acceleration unavailable
Flash Stage3D Baseline profile: Software only, hardware acceleration unavailable
Compositing: Hardware accelerated
Rasterization: Software only, hardware acceleration unavailable
Threaded Rasterization: Enabled
Video Decode: Software only, hardware acceleration unavailable
Video Encode: Hardware accelerated
WebGL: Hardware accelerated

I was also advised to install a blob, but I could not find the meaning of this word and
generally did not install it. What is it?
Here .. In general, what do I need to install and how? Here are the specifications of the video card -

pc:~$ lspci -vnn | grep -i VGA
00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Wrestler [Radeon HD 6320] [1002:9806] (prog-if 00 [VGA controller])

A blob is a proprietary driver without published sources. Compiled binary file, loading of which initializes the device as intended by the manufacturer.
Alsoo, opera?
Chrome and Firefox block drivers because they are buggy, but there is a way to unblock:

EDIT:
Works fine after adding the "chromium-args": "--enable-webgl --ignore-gpu-blacklist" line to package.json

Chrome on Linux
WebGL is enabled on ATI/AMD GPUs with proprietary AMD drivers 8.98 or newer.
