No, but you could take the RSS feed and add it to a widget. - Araceli

@araceli, could you tell me how can I do that?? - me0wth

Use http://www.widgetbox.com/ and put your FF RSS into it. I don't know about putting it in the sidebar, but you can put it in an entry. - Araceli

JavaScript, flash, and embeds aren't allowed in styles (http://www.livejournal.com/support...) but you can usually use them on the profile or in a future-dated entry to stay at the top of your journal (http://www.livejournal.com/support...) - AzureLunatic

I think the only place you can really put a good widget would be your profile. I know on my profile I have different media stuff added, I have a FF box but I know it's not the java enabled one. my sn on LJ is anya1976 if you want to check out the stuff i do have on my profile - Angela P.

I have a widget in a sticky post on my LJ. - Araceli from iPhone
