the Safari dev. community has the same problems
for example: Note to Saft users: Using both Glims and Saft on the same browser could have unexpected results.

I bought a Saft license and used it while I went through my Safari phase. At the end, I really didn't like how deeply it got its hooks in but was worth it for the undo close tabs alone. Uninstalling Saft can be a pain in the but unless you know specifically how to uninstall it. Otherwise, keeps coming back. Like a piece of Windows malware.
