The best Google Chrome extensions is, without any doubt, AdBlock [do not confuse it with his “little-big” brother AdBlock Plus]. I simply can’t live or even think to browse the web without having it installed anymore. Nowadays nearly all webpages are full of ads and there are so many types that you can even distinguish between them: banners, pop-ups, pop-unders, etc. and they all share the same aspect: intrusiveness. Not only, in fact they can even follow and track your browsing experience site-by-site without caring about your privacy and/or giving you to ability to opt-out from this process. Luckily AdBlock give you the possibility to block ads on all websites even before they get loaded from your browser and it also blocks companies which tracks you on the web [like Google’s DoubleClick] at the same time. Be sure to select EasyList and EasyPrivacy from the blacklists menu.
The second best Chrome extension in my opinion is Auto HD For YouTube by JRA Apps. This simple and lightweight extension makes your YouTube experience more seamless by automatically selecting the video quality you prefer for any videos you watch. If you’re like me in fact selecting video quality for each videos is a pain and if you’re also as lazy as I am sometimes you prefer watching a video at the ugly resolution of 240p instead of selecting 1080p or 720p and waiting for the YouTube player to reload the entire video from the beginning with the selected quality. This extensions also works with embedded videos, unlike other similar extensions.
The third best Chrome extensions is DoNotTrackMe by Abine. This extension, also available for Firefox, protects your online privacy by blocking nearly all tracking and advertising companies from seeing which sites you visit, videos you watch, purchases you make, etc.. If you use it in conjuction with AdBlock your browser will be able to protect your privacy from 99.99% of websites out in the internet. It needs no configuration so it does the job for you right after you install it.
