Up until this point, I had been using several Safari Add-ons to bring functionality that I missed using Firefox. Such as, undo closing a tab, always open in a tab, remember last session, etc. I had been using ForgetMeNot and Safari Stand through SIMBL, which worked but I think ForgetMeNot made Safari a slight bit more unstable. I’m also too cheap to use anything that I’d have to pay for, such as Saft.
I was happy to find there’s now a single add-on that would do everything I wanted, and more: Glims. Yes, it’s in beta, but I’ve been using it for the past week with no problems, and I’ll keep using it as long as it’s free! :)
