When you search in Firefox using the address bar, the results are forwarded to the AVG search website which blocks out a lot of content that Google would show otherwise.
AVG has changed the Firefox keyword.URL setting.
- Open Firefox.
- In the address bar type about:config and press Enter.
- In the “Filter” input box type keyword.
- In the results that appear, right click on keyword.URL and click Reset.
- Restart Firefox.
