NoContext - Enable Right Click & Select Text от wcoding

Clicking on this extension will bring back your right-click context menu and ability to select text on websites that may have mangled its true purpose. When active for the current tab's domain, you'll see a red "!" badge on the corner of the icon. It will remember the domains you've activated previously and automatically activate when returning to those domains. (Some websites use multiple domains, so you may need to activate it for each of the subdomains, or use wildcards in the Options menu!) You can always click on the icon again to deactivate when visiting the current domain.

Updates:
1.0.13 -- Better iframe handling. Settings now carry over into incognito/private tabs.
