What can I do about a site that says "Incompatible Browser" and suggests I get internet explorer when I'm using Linux?

Below is part of the site I got while applying for a job at http://www.securitas.com/us/en/Career/Come-Join-Us/Start-On-line-Application/ I'm not sure how I can use their "career services system" in Linux, much less Firefox.

Incompatible Browser

I have seen this on occasion, and one must thus ask this serious question: "Do you really want to work at a company that cares not about security, or even open standards?"

If the answer is yes, assume the position and boot into Windows. Otherwise, move along, you know you can do better!

That is a problem with the user agent that is not recognized as a standard Firefox user agent.

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.12) Gecko/20101027 Linux Mint/9 (Isadora)


You can set the pref general.useragent.override to override the current default user agent.

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12


Be aware that if you use this method that you will have to update that pref yourself after every Firefox update to reflect the new change. Keep the first part and change the Linux Mint/9 (Isadora) to the current Firefox version reflected by the Gecko version rv:1.9.2.12. The 1.9.2 part specifies the Firefox 3.6 branch and the .12 at the end the current Firefox version 3.6.12. So if that changes to rv:1.9.2.13 then you have updated to Firefox 3.6.13
