New Tab to Homepage od Daniël Troost

How to change redirect page/homepage
Go to about:preferences#home by typing it in the address bar and change the url(s) set at "Homepage and new windows".

Or go to about:config, search for "browser.startup.homepage", and edit its value.

If you have multiple homepages set only the first url is used.

Permissions
The "Read and modify browser settings" permission is required to get the browser.startup.homepage setting from your browser config.
No other setting is being accessed, changed, nor stored.
