Reddold is a WebExtension which redirects reddit urls like
https://www.reddit.com/* to https://old.reddit.com/*.
It has been tested on Firefox and Vivaldi, but it should also be compatible with at least Chrome/Chromium and Edge.
The redirection happens before the original request completes.
That is, it doesn't wait for https://www.reddit.com/* to load before redirecting
to https://old.reddit.com/*.
Install it from addons.mozilla.org here or manually download a release from here.
