STEP 1 - Open the Chrome browser.
STEP 2 - Go to the upper right hand corner and click on the icon represented with 3 lines.(Customize and Control Google Chrome)
STEP 3 - Go to Settings
STEP 4 - Go to the left hand column and click on Extensions - a list of extensions will be generated.
From here you have the option of running in a Developer Mode - this gives you a quick way to update/upgrade the current list of extensions. Extensions can also be enable/enabled allow the extensions to remain, but not run or take up space. The user also has the ability to completely delete any extension...which we suggest it you start noticing a lag in your Chromebooks operation or a web browsing hangups.
