Redlib Redirector — dfisch15

Firefox extension that redirects reddit.com to a redlib instance, and optionally auto-applies your redlib settings there.

Features
Redirect to redlib: any reddit.com (and subdomain) page is redirected to your chosen redlib instance. Direct media links (redd.it, i.redd.it, v.redd.it, preview.redd.it) are left alone since redlib has no route for them.
Private windows by default: redirection only happens in private/incognito windows unless you opt in to regular windows too, so normal browsing is unaffected out of the box.
Auto-apply redlib settings: since private windows don't keep cookies between sessions, the extension can re-apply an exported redlib settings string on your behalf so your preferences (theme, layout, etc.) are restored automatically each time.

Menu options
Click the toolbar icon to open the settings popup:

Redirect target: pick which redlib instance reddit.com redirects to (safereddit.com, redlib.catsarch.com, red.artemislena.eu, or redlib.privadency.com).
Windows: check "Also redirect in regular (non-private) windows" to extend the redirect (and settings auto-apply) beyond private windows.
Auto-apply settings: paste a redlib "export settings" string here to have it restored automatically after redirecting.

Click Save to persist your changes.
