Firefox loads the wrong site when you attempt to visit a site from the location bar history, if that site is on an intranet and contains a space in the name. These sites can be visited if you type the address by hand, and they work from if you select the link from the History tab, but they don't work if you try to select them from the drop-down list that appears under the location bar. If I add the domain name to the URL, the site will load from the history. (for example, http://server.domain.com/share/look at this file.html) It still doesn't work if the domain.com part is removed. Here are the steps to recreate the bug: 1. Visit an intranet site that has a space in the name. http://server/share/look at this file.html 2. Close the tab 3. Type part of the file name in the address bar 4. Select the site from list of suggestions (it will appear as server/share/look at this file.html) 5. Firefox will use the URL as a search term in your default search engine
