yes; on my chromebook i have installed Ublock origin, i have never heard of anyone using 2 ad-blockers, I don't think that is necessary.
Check here
https://chrome.google.com/webstore/category/extensions?hl=en-GB for adblock plus
If you are a windows user; install chrome on your windows machine then
1) import all bookmarks from firefox; install extensions required
2) Sign in (or create) your google account
3) Make sure sync is enabled
Then after the sync is complete, sign into your new chromebook with your google account, all bookmarks, history extensions will be synced across.
I only use a windows laptop for VPN'ing in to work; chromebooks rule, especially with android apps.
