Why is my Google Chrome glitchy?

[663]

Whenever I click a tab, the browser closes. Whenever I press enter after I type something in the site bar, I cant do it anymore after I press enter. Tell me how to freaking fix it! Oh yea and whenever this crap happens it removes my add-ons!
It only happens sometimes. Whenever I restart my computer its fine, for a couple of weeks.

I don't know why it shows update 2. Sorry about that!

Do you have an anti-virus software installed in your computer? It could be a cause of virus.

Check your extensions. They are not made by Google themselves, and many have bugs or unintended side-effects which cause problems, even in areas the extension itself doesn't touch.
