Copy & Paste works fine with some patches from OpenRepos.

I also find the official browser quite good (the choice of Gecko is very welcomed) - the only things that bug me are:

• some videos play distorted
• it cuts out few seconds at the end of a video (you hear only sound) - both these two are not such a big deal, though, I just use a Youtube app for playing videos
• slow tab switching
• sometimes the page changes under your finger and you click somewhere you didn't want to

Other than that, I enjoy using it. I agree that a good browser is crucial on a tablet - take an example of HP Touchpad, but Jolla's browser is already miles ahead of it.
