Thank you.

Okay, so I type in my query, and instead of using the default search engine I specified, it decides I must mean search using php.net's internal search engine, and so I have to manually override that? And this doesn't happen when i type in 'bing' or 'duckduckgo', why?

Hi jacob.ian.lee, at the moment before you submit the contents of the address bar, what does the top row of the drop-down say that Firefox will do?

The reason I ask that is it's possible to define keywords for search engines or bookmarks. Firefox should tell you in the top bar if it's going to do something different from sending the address bar contents to your default search engine.

says " php.net: search terms"

Most likely you have a "smart bookmark keyword" set up for some URL on php.net.

If you open the Library window ("Show All Bookmarks" or Command+Shift+b) and search for php.net in the little search box in the upper right, you can click each bookmark in turn and glance at the bottom of the screen to see whether any has php assigned as its keyword. And if that is more annoying than helpful, you can delete it or change it to something like pn that you would only type intentionally.

Was that it?

Thanks, jscher2000, it looks like I had once added a bookmark:

www.php.net/%s

Deleting the bookmark removing the (now) unwanted behavior.
