Been using this one for over a decade. Works with Firefox’s bookmark keywords feature.
Make a new bookmark, set the link as follows:
https://lemmy.world/c/%s (or your own Lemmy instance)
And in the “Keyword” field, use “c” or “lemmy” or whatever.
Now, when you want to visit a specific Lemmy community on your home instance, you can simply type:
“c community_name” in the address bar, or “lemmy community_name” in Firefox and it will automatically open the community.
This works in Chrome as well, also this is a nice (firefox) addon to go along with it so you can select text and right click to use one of your keywords.
You can also combine it with bookmarklets for more advanced things like
javascript:void(location.href='http://www.google.com/search?&q=site:'+location.href.split(%22/%22)[2]+'+%s')Which lets you search the current site using google.
