How to make your own extension for Chrome?

Can Chrome extensions inject JavaScript?

When I load a page and add a simple Google Maps script to the page, the map works fine.

However, this works only once per page, whereas I need to refresh the same page to see the changes and for the first time it loads, Chrome says: We don't want extensions to execute any scripts. How can I change the rule for a specific extension? Update 1: I cannot see any extensions listed under the extensions menu, but if I add my extension's name in about:flags, and reload a page, I can see it. Update 2: I tried removing Chrome and installing it again, no change. Here are my flags before and after: flagextensions == true # Default. Flagrununpacked == false # Default. Flagdebug == false # Default. This is caused by the --no-extensions flag in Chrome. You can safely ignore it or remove it.

To remove it go to chrome://flags/#start-page-with-eula, disable "No extensions" and restart your browser. If you have another (main) profile you might have to quit your other browser before you can disable that flag.
