[Feature request] redirect nitter mirrors to actually set mirror

[derdershat]

Hi and thank you for this nice extension!

could you please consider to redirect a nitter mirror to actually set mirror?

If I have saved a bookmark par ex with nitter.net and I open it again, sometimes(often) the message "use another instance... Instance has been rate limited" pops up. Here it would be awesome if it redirects automaticlly to the set Instance in your extension.
