If you use Mastodon through a desktop computer, you can install a special browser extension called FediAct which lets you directly interact with other servers' websites:
:firefox: FediAct for Firefox
https://addons.mozilla.org/en-US/firefox/addon/fediact/
:google: FediAct for Chome
https://chrome.google.com/webstore/detail/fediact/lmpcajpkjcclkjbliapfjfolocffednm
This can be very useful if you are following web links to other servers, for example in the listings on https://fedi.directory
