Highlight My Site
What it does
Highlight My Site lets you provide a list of domains you're interested in, and then whenever you do a Google search that matches a page on any of those domains, it highlights that result in yellow.
Why it's useful
If you're a webmaster, you may find it a convenient way to check at a glance how you — or the competition — fare in the search rankings.
Other users will find it handy if they have a set of sites, for example Wikipedia, where they prefer to get their information. With this extension they can quickly jump to the search results that come from their trusted sites.
How to use it
First, make sure you're using Firefox, version 1.5 or later. It shouldn't matter whether you're on Windows, Mac, Linux, or anything else.
Second, install the extension by clicking this link: download Highlight My Site. If Firefox says that it has prevented this site from asking you to install software, follow the prompts to add freesoftware.cr.uz to the allow list.
Firefox will ask you to restart the browser (not your entire computer) in order to complete installing the extension.
Then, once it's installed, choose "Add-ons" from the Tools menu. Locate "Highlight My Site" and click the Preferences button. That will bring up a window like this:
Enter as many domains as you like, one per line, just like in the screenshot above. To include all subdomains, use a * like in the wikipedia example. Click the "Google" checkbox to activate highlighting for Google search results. Then click OK to save your changes.
Then do a Google search. If everything worked according to plan, any search results that come from the domains you entered should be highlighted in yellow, like in the screenshot below:
What if you have problems?
Eventually I will set up a comments section here. For the moment, please use the mozilla.org page for this extension to discuss any problems you encounter.
Add support for other search engines, such as Yahoo and MSN. At the moment it only works with Google.
When saving the preferences, check to make sure the domains are valid, and provide a chance to fix them if they're not.
Add the ability to store multiple sets of domains, each with its own color coding. For example, someone might want to tag some sites green for "informative", and others red for "the competition".
