In Chrome, click on the spanner symbol in the top right corner, just below the red box with the white cross.
Click on Options
On the left side, click on Personal Stuff
Next to Browsing Data click on the box marked Import data from another browser.
You should find that already filled in with the options ticked. If not, click on the down arrow to choose the browser you want to export from.
I downloaded Chrome a few days ago, & was surprised to find it did this automatically from Firefox.
