Leocg thanks for the heads up on the alternative way. I do know about that method though and it is still convoluted and time consuming for me. You have to trawl through all your folders and subfolders to find the right one. Doing it the chrome way is easier because you can simply click on the folder and then bookmark by right clicking. Either in that folder or in a sub folder in that folder.
Bookmarking methodology, for me, is probably one of the biggest usability concerns in any browser.
