Ive had the pro version for several years now. It used to be quite a strong offering. It always had issues with crashing and difficulty seeing text boxes as one was typing.
But the last few updates have really destabilized it. Many of the once great features have been stripped or reduced to shambles.
I wont be melodramatic here. Its still slightly better than Safari. However, Im sure there are much better paid browsers out there.
Its glitchy, slow and often frustrating. Im definitely going to retire this once loved gem soon if Adblock and other features dont return soon.
