A few words of thanks would be greatly appreciated.
FireFox - Change the interval for updating RSS feeds
The Live Bookmarks updates feature of Firefox will check for new RSS update at each hour, but if you feel that the time interval is to great, you can modify it!
Open Firefox:
In the address bar, type the about: config and press Enter.
Click I'll be careful, I promise!.
Right click on any of the entries and select New > Integer value.
Name the new option as:
browser.bookmarks.livemark_refresh_seconds
Click on the OK button and specify the number of seconds between each update - the minimum allowed is 60 seconds .
