List of Chrome Extensions you should try!

CLEAR

Extension:

When available always prefer a bookmarklet over an extension

Since control is within your hands when using bookmarklet

Extensions I.. don't like...

Extras

use shift+Esc to check memory taken by each extension

disable extensions with extension manager so chrome doesn't take much memory at once
disabled extensions only slowdown opening time of chrome

when selecting which extensions to keep,remember specific site extensions don't degrade performance

many suspicious extensions exist, and if an extension asks you to sign in without extra functionality, then it is prolly garbage
