Gave it a quick try. Annotations didn't work at all in Fierfox, but all annotation types (underline, highlight, etc.) worked as expected in Chrome.

I haven’t had the chance to test annotations in Firefox yet, so thanks for pointing that out. I’ll check what’s going on there, good to know they’re working fine in Chrome.

If you haven't checked yet, you'll notice:

    Uncaught ReferenceError: TouchEvent is not defined

Yep, that’s exactly the issue! I’ve fixed it so it no longer throws the TouchEvent error in Firefox. Thanks for flagging it.

Sounds like a mobile-vs-desktop issue, since the error mentions TouchEvent. The Firefox error fires even when just hovering the cursor over the PDF in View mode, and text is also not selectable.

While I'm here, a suggestion to add Undo/Redo; yes HN, I know I could make a PR..

Thanks for pointing that out! I’ve fixed the Firefox issue. And we actually already have Undo/Redo on the annotation toolbar.

Redaction doesn't seem to work in Firefox either. Otherwise looks great!

Thanks! The redaction issue in Firefox should now be fixed.

Would love some more info about how redaction works. We currently use Acrobat Pro for redaction mostly because of 'trust' issues, but I'd love to replace it with a web tool. I just need to convince our CFO that it's safe.
