How to block annoying facebook and other social network widgets
That's pretty simple with the Adblock Plus, here see this tutorial - http://www.techairlines.com/2010/12/12/block-social-buttons-widgets/
short summary:
- Install Adblock Plus
- Install this filter: https://monzta.maltekraus.de/adblock_social.txt
Apart from using a classic ad blocker and defining your own rules, I've found Ghostery quite helpful. It blocks most of these add-ons, like Facebook Connect and Twitter, also Google Analytics and all kinds of ad networks.
The idea behind it is to stop those massive ad networks from tracking your browsing habits.
The Fanboy Annoyance Block List for uBlock Origin, AdBlock Plus or any other browser extension that can use AdBlock Plus filter lists in Firefox or Chrome...
...Blocks Social Media Content, In page Pop-Ups and other annoyances; thereby substantially decreasing web page loading times and uncluttering them.
I personally prefer the Fanboy Annoyances block list to the Antisocial list, as it blocks more than just social media content (also in-page popups, newsletters, unnecessary links, self promos and other content that clutters sites unnecessarily). See a comparison between the Antisocial and the Fanboy Annoyance Block List here.
...Or, you could install the Fanboy Ultimate List, which combines the Annoyances block list with EasyPrivacy (blocks trackers), and EasyList (main ad blocking list; a lot of ads are also trackers).
The Anti-Facebook Filters might also be of interest. It is specifically for blocking Facebook content.
