Possible Logo Quality improvement Fix for Fast Dial 2.22b only

This is definitely not for the faint hearted !!

Thanks to user Darkobra for bringing up this question. and for his work with telega to find a resolution to this

The question was first brought up on Userlogos here


This was a fix made by telega for 2.22b only
(Will not work in 2.23b1)

Below is the modified fastdial.htmal file

fastdial.html is to be found in
extensions/[email protected]/chrome/content

This whole file needs to be edited in to replace the previous file in the regular Fast Dial 2.22b.

Best done with 7-zip
As then a modified xpi version can be reloaded easily to Firefox

Here is the modified code
