How Do I Change Browser Identification to Firefox?

  • I got Opera 11.52. I want to change my Browser Identification to 'Identify as FIrefox' for all webpages.So, I want to make this is a global change, not just for one webpage. How do I do this?

  • Go to opera:config and change the number at "Spoof UserAgent ID" Firefox is number 2.

  • Don't know about 11, but Opera 12 has a Custom User-Agent field in opera:config where you can goto in Firefox, select its user agent, copy it and paste it into the field. That way, you get an updated Firefox UA string.

    Opera will still expose window.opera in Javascript though. If you create a folder and put hidewinopera.js in it, goto "alt + p -> advanced -> content -> javascript options -> choose button" and choose that folder, it can sometimes help to further hide Opera.


    delete window.opera;


    window.opera = undefined;

    Doesn't work for everything though.

    The probably with all of that though is that Opera might get advanced code that it can't handle. But, it's something you can mess with.

  • Go to opera:config and change the number at "Spoof UserAgent ID" Firefox is number 2.

    Hey leocg.. That looks like the solution. Can you tell me what numbers are associated with Opera, IE, both masked and identified, etc? I'd appreciate it if you would provide me with a run down of what all the numbers are for all these user agents.

    Also, Can you oplease tell me the difference between 'Masked' and 'Identified'? Thanks!

  • @xxlook click on the ? icon on the right of that field, it will show you the numbers.

    Masked means that there is no mention of Opera on the ua.
