You're right chronicman69 - I can no longer drop & drag links either.. That, and countless other changes were encountered when I mistakenly switched to Firefox 4. I'm going to try using some of the instructions others have put on here of ditching Firefox 4 until they get the bugs worked out.

I wish Mozilla Firefox would issue a statement on all of the complaints they're receiving.. But until then, kudos to the volunteers logging on here who are trying to help.

Instead of dragging the link, try dragging the favicon/site identity button that is on the left hand edge of the address bar onto the bookmarks toolbar. That should allow you to add a bookmark to the bookmarks toolbar.

Thanks TonyE! That worked like a charm.

You're welcome

I ditched 4.0 and went back to 3.6.17 but I can't drag and drop with it either. The Favicom idea didn't work for me either. Once in a great while it will work, but usually that ends up screwing up my bookmarks and everything being re-arranged. How could something so simple and basic NOT WORK anymore?

I have read that there are about 5 or 6 other add-ons that also inhibit Drag and Drop functionality, not just the Torbutton add-on. The list is somewhere in the main Firefox support section (but it's tough to find the answer there twice).

The generic add-on troubleshooting page is at:
