Are you just trying to find an addon if so use

• https://addons.mozilla.org/en-US/firefox/
• or if it is a new search engine for the search bar
  http://mycroftproject.com/search-engines.html

It may have helped if you had included the full troubleshooting information, but we will ignore that for now it may not be essential.

Please however say exactly what the software is that you are installing

• Fullname and version
• Where it is downloaded from
• Home or support website of that software

Perhaps a screen shoot of the problem will help us undersatand what you are seeing, you may attach one using the button under where you write message replies

Note Firefox has a few search methods but they all use whatever search engine is selected in the search bar.

What is it you are attempting to do, install some sort of search toolbar ?

If so I hope you checked out reviews of the product and took care not to download other un wanted software at the same time.

I clicked the download link from https://addons.mozilla.org/en-US/firefox/search/?atype=4. I tried this with YouTube and IMDb search engines. I am not sure where the actual add-on is from as Windows 7 doesn't offer that sort of unimportant information to mere mortals.

The search on the search bar that Has as an icon a green jigs-saw piece and the title Firefox Add-ons is specifically for searching for Firefox addons, as you may have guessed from its name. It is available from the addons pages.

It will take you to pages such as https://addons.mozilla.org/firefox or parts of that site. The page https://addons.mozilla.org/firefox/search/?atype=4 is actually many pages with over 3000 items offered.

If with the Firefox dd-ons search engine selected in the search bar you type in IMDb that will give you something like this

• https://addons.mozilla.org/en-US/firefox/search/?q=IMDb
• 1 including https://addons.mozilla.org/en-US/firefox/addon/imdb-search-1/?src=search
  1. that opens to a page with a download button, labelled [Add to Firefox] once clicked that should download the search engine, and give you an option to install it. Other searches for addons work in a similar way.

That specific option may not be a good choice the add on did not actually work for me.

• Note many others available from http://mycroftproject.com/imdb-search-plugins.html

IMPORTANT once you have use the search remember you may wish to reset it to whatever you use in day today browsing. That may be Google. Note the location bar, and other Firefox searches all use whatever is currently selected in the Search bar.
