Everything related to search doesn't work after upgrading to 45.0
After upgrading from 44 to 45, searching from the address bar will just go to http://[my keywords] and raises connection errors. Search from the search box gives no reaction at all. Clicking the Search tab in Preferences shows nothing (just staying in the previous tab). Disabling all addons and clearing cache didn't work.
Chosen solution
Try to delete the search.json file and possible search-metadata.json and search.sqlite files in the Firefox profile folder to reset the search engines to the default.
You can use this button to go to the current Firefox profile folder:
- Help > Troubleshooting Information > Profile Directory:
Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder - http://kb.mozillazine.org/Profile_folder_-_Firefox
Firefox will rebuild the search.json file from the default built-in search engines that come with Firefox and the searchplugins folder in the Firefox profile folder.

Update to 45.0.1 which has a fix for two different search engine regressions.
