What it does, it does the best (this is my fourth paid manager).

However...
They no longer support Firefox. On their homepage, it even says "Install on Firefox". I contacted email support (and they responded the same day!) and "Unfortunately, some time ago Firefox..."

So that just leaves chromium browsers -- no Safari, no Opera, no Firefox, no DuckDuckGo. Support did say they were working to "...get it published as soon as possible!" Hopefully, they are working on it so intently they forgot to take down their homepage install button.

Support for multiple browsers is why I purchased it, based on Q&A here on AppSumo. I use both browsers a lot, this product is pretty worthless at the moment. Since I have a lifetime subscription, I guess I'll set a reminder to come back in 6 months -- unless a better product is released.
