But let’s face it, I don’t know if it can really replace Safari and Firefox for now. It’s stable, fast and definitely gets the job done. I’ve been plain’ around with the latest build of Stainless for a while now, and I must admit I’m really satisfied. So, you can fire up Stainless, start two single session tabs and log into Twitter with two accounts. Last, another thing I liked about Stainless is the possibility to start “single sessions” tabs: it’s not about the process, it’s just that you’ll be able to log into the same websites with different accounts in one Stainless instance.
