Setting up a new search provider

I wish to add a search provided to Firefox, and I have the needed URL (it’s a wiki, but not Wikipedia). Some browsers let me enter one manually, but I can’t find a way to do this in Firefox. Do I need to create an add-on to do this, or is there an easier way?
Thanks!

Check out this recently approved search add in -

https://addons.mozilla.org/en-US/firefox/addon/putlocker-is-search/

Their code is nice and simple. It’s basically a template, just fill in your URL and submit it to AMO (addons.mozilla.org)

Okay, I see what you mean, though I’m not sure if I’m setting everything correctly. Is there a way to test it?

I see an"Install addon from file" option, but that requires a .jar or .xpi which is a problem since this is an xml.

Test what?

You should be able to install the XPI.

Okay, this is the first time I’ve experimented with these addons, so you’ve complete lost me, and I hate to require you to coax me through ever step.
However, if you don’t mind, what xhtml?
I’m rapidly getting lost here. In Chromium, you can just type into the pretty little boxes the search URL, search name, and hit okay, but I guess nothing’s that simple here. I can tweak the code from here: https://addons.mozilla.org/en-US/firefox/files/browse/540470 but I’m not sure how to package and deploy it.

Oops excuse that! I mixed the reply here from another topic.

How to test:

  1. Download their XPI on that link I gave you.
  2. Rename to zip
  3. Extract
  4. Open the xml file
  5. Change the paramaters (like <Url
  6. Rezip the contents
  7. Name to xpi
  8. Go to about:debugging
  9. Load in your xpi

I can’t download the zip–I get a 403 Forbidden error. I can only see the code displayed on the page. Any ideas?

P.S. No problem thanks for the assistance!
