One possibility is a flaw in the site's browser detection script. Is there a public page (no login required) that gives the same error? A volunteer could take a look.

Firefox also has a feature allowing you to lie to particular websites about your Firefox version. This takes a little work to set up, though, so let's try to identify the problem more precisely first.

Also could be an old script that doesn't recognize a 2 digit Firefox version number and sees Firefox 23 as Firefox 2. We had a number problems like this when Firefox 10 was released.

The DocQ site only seems to work with Firefox 18 or lower (Firefox 19 give a warning bar at the top)

You can override the user agent for a domain to make it see a specific Firefox XX version (in this case Firefox 18).

• Name: general.useragent.override.xxxx.com (replace xxxx.com with the actual domain)
• Value: (rv:|Firefox/)\d{2}#$1XX (replace XX with the needed Firefox version)

You can open the about:config page and create a new String pref via the right-click context menu

• Name: general.useragent.override.docq.com
• Value: (rv:|Firefox/)\d{2}#$118
• http://kb.mozillazine.org/about:config

You can toggle site specific overrides on/off via the general.useragent.site_specific_overrides pref.

If the website still doesn't work properly then you can try the Firefox 18 portable version.

The portable version comes with its own profile folder and doesn't interfere with the currently installed release version.

The site works OK even with that banner at the top. Love you guys and Firefox! Thanks loads! Paul Mattson
