Falkon browser startpage search does not work

Installed Falkon browser and noticed when I search with startpage it just redirects me to startpage homepage.  Played with the URL and postdata settings some and it just kept doing the same thing.  Even if I used a format that worked in Firefox the same thing would not work in Falkon.  Eventually I got this format to work for using Falkon and startpage as the default search engine.

Falkon browser no menu and certificate errors

 Recently installed Falkon web browser and right away I was getting SSL certificate errors on every site I went to.  Then I noticed there was no menu button / icon either.  Seemed very odd.  When trying to find out what Falkon I installed realized I accidentally installed this

falkon.i686

instead of this

falkon.86_64

After I switched to the falkon.86_64 package everything was normal.
