So many choices.

I have rolled woth Chrome for some time now, but I constantly tweak the experience with different plug-in / extensions.

Spell check (low hanging fruit there) and pop up blocker are old time go to, but what others do you have?

Great new extension for chrome

"The Great Suspender" -

Has your computer ever starter to run slow and you open up task manager to about a dozen chrome tabs eating your memory? This solves that problem. You can set a timer, and this extension basically closes those tabs. The cool part is the tabs don't disappear the just go comatose, you can go back to them and refresh.

Really improves performance of pc.

Password manager, I like Last Pass.

An ad blocker is a must, not just pop up blocker, uBlock Origin is my current blocker of choice.

If you use Evernote, the clipper is great for snagging info for later.
