Set the source url, set the destination url, et voilà, you have a redirect! Now all requests that try to open that source url will get automatically transferred to destination. We are also redirecting "before request", so the source won't be loaded at all, instead, it will be completely bypassed. Still not satisfied? No Worries! this addon comes with a few additional features too, read on,

Deep Redirects - When turned on, redirection rule will apply to background requests too. This is especially useful in redirecting those pesky background third party request to whatever destination you like.
Regex Matching - When turned on, matching is done based on regex patterns. Use this to set single destination for multiple URLs using regex patterns.
Notifications - Notifications can be selectively turned on or off for each redirect. They get triggered when a redirect happens.
Header Copy (Advanced) - Copy POST request parameters to GET query string. This is especially useful in converting link handling POST request to link handling GET request

Some examples of use cases

Redirect reddit to old reddit directly ("www.reddit.com" -> "old.redirect.com") or via regex matching to handle multiple cases ("http(s)?://(www.)?reddit.com" -> "https://old.reddit.com").
Redirect duckduckgo to non-js duckduckgo ("duckduckgo.com" -> "duckduckgo.com/html")
Redirect a blocked site to its proxy with background resources also loading properly from proxy site by setting Deep Redirects ON.
Block a domain completely by redirecting it to a non-functional site and setting Deep Redirects ON. This will also block any third party background requests to that domain.
Transfer POST search queries (eg: html.duckduckgo.com) to GET queries (duckduckgo.com) using Header Copy
