Toolbar requirement is dependent on country you're in.
For Firefox there is (in addition to original toolbar) this addon:
https://addons.mozilla.org/en-US/firefox/addon/3843
It won't work in K-Meleon, but I looked at the source and it just creates fake cookie and sets user agent string to IE6, nothing more.
For someone with expirience in K-Meleon scripting, it must be a ten minutes job.
Or it might be possible to enter required data manually in cookies.txt in K-Meleon's profile.
