TwitterTweetFilter_WebExt per Leejo, Neil

EDIT: In June 2017, the Twitter began to support the own 'Muted Words' feature. You don't have to use this addon 'TwitterTweetFilter_WebExt' anymore.

Setting in the Twitter Menu -> 'Settings and privacy' -> 'Muted Words'.


Configurations
========
- configure words list you don't want to see. (Regular expression)
Add-ons -> Extensions -> TwitterTweetFilter_WebExt -> Set 'filter words list' -> Save

KNOWN ISSUE ( was fixed in version 1.4)
============
- Once go to other pages like 'https://twitter.com/<user>' or like 'https://twitter.com/<user>/lists/<list>', this addon will not work any more.
- Just reload 'https://twitter.com/' when this issue happened.
