Thread/Post Updater

[fms007]

Hi
I was hoping to get your help on this.
Is there any software/addon for Firefox by which one can keep a track of different threads in different forums.

Meaning let us say i want to keep track of a thread(only one) on BSNL section and i want to keep a track on another thread in some other forum like afterdawn (just example), a third thread on some other forum (total different forum),
and i want to load all these specific threads without having to go to each section in each forum....as u spend a lot of time doing that

Subsription of threads is for one forum...meaning you can subscribe to different threads in that forum, but you have to go to that forum only.

What about a program/addon where you can view different threads of different forums and maybe even check if any new post has been updated in that particular thread.
