In the "More system details..." for your post, it shows an ancient version:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.17) Gecko/2009122116 Firefox/3.0.17 (.NET CLR 3.5.30729) FBSMTWB

It could have something to do with that acronym at the end, which I think is associated with one of your add-ons.

To see your true current version, you can check Help > About Firefox.

If your true current version is 6.0.2 (today's version), then you may need to clear a setting using the about:config preference editor. Here's how:

(1) Type or paste about:config into the location bar and press Enter. Click the button promising to be careful if it appears.

(2) Type agent into the filter box and wait for the list to be filtered.

(3) Right-click general.useragent.override and choose Reset to return that preference to its default value.

Any luck?
