I figured out how to make the User-Agent Switcher for Chrome (AKA Chrome UA Spoofer) work - All the time. Change the default custom agent!
- Go to the Extensions page - Enter Developer mode
- Go to the User-Agent Switcher for Chrome and open "background page" - which opens the Developer Tools window
- Look for spoofer.js and open the Javascript editing window for it
- Search for: UserAgent("Default","","","",!0,"Chrome"))
- Replace with: UserAgent("Default","Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20120427 Firefox/15.0a1","Mozilla, Inc.","F15",!0,"Firefox")) - or another agent if you like - I think a few others work too
- Save the file somewhere - right clicking gets you the save as option. The save seems not to work - won't over-right for me.
- Go to C:\Documents and Settings\YOUR USERNAME HERE\Application Data\Opera Software\Opera Next\Extensions\djflhoibgkdhkhhcedjiklpkjnoahfmg\1.0.36_0 or where your extension file are
- Make a backup copy of spoofer.js
- Copy the edited copy of spoofer.js from #6 here - over-right it.
- Start Opera
note: If you have a Google search open, refresh it. It should work now!
note: To go back to original default, delete the spoofer.js file and replace it with the original you backed up
I can see this having problems in the future as things change, or possible consequences on other web sites, but it fixes the old-style search results issue.
