My rule for reddit:
reddit: www -> old
Redirect: https://www.reddit.com/*
to: https://old.reddit.com/$1Also useful, for example, if you want to be the one in charge of whether your browser uses the desktop version of Wikipedia rather than the mobile one:
https://en.m.wikipedia.org -> https://en.wikipedia.org
Redirect: https://en.m.wikipedia.org(\/.\\*)?
to: https://en.wikipedia.org$1Just go to your Reddit account settings[0] and click "Opt out of the redesign" at the bottom. (Or on old Reddit you uncheck "Use new Reddit as my default experience"). Once you do this you'll now see old Reddit on www.reddit.com.
https://reddit.com/prefs is similar but not actually the same page and, conversely, this old page will only load with the old interface regardless of your preference as it doesn't exist in the new interface.
It’s frustrating that there are clear regressions on mobile even for a mobile centric overhaul.
On mobile particularly if logged out (or particularly particularly if in a private browsing mode) it's quite aggressive about trying to push you to the app, or letting you view only a couple comments in a thread before saying you're not allowed to see more, or not letting you view some subs at all. "Old" reddit doesn't do any of this.
