This question reminds me of another interesting way to use a bookmark with a sidebar. Not trying to hijack but mention it here in case it helps with MickG's scenario.
Easier to demonstrate than explain:
1. Create a bookmark for aulro.com
2. Right click and go to properties
3. Turn on the "Load this bookmark in the sidebar" option and "OK"
4. Now left click on the shortcut
It should open the aulro page in a sidebar of the current tab. You will not see all of the page but you should see a list of the latest threads.
Why is this useful?
You can now use this list of threads as a menu. Select one of the threads and it will open in the tab leaving the aulro page as it is in the sidebar. Saves you having to go back and forth all the time. I use this for the general chat bookmark as well. Okay also for Google when you expect a small number of useful results.
You can still use the drag and drop option as described in the previous post (#10) or right click it for normal operations. It only affects the left click operation.
