Great add-on, couldn't work without it anymore, but it doesn't work properly after updating Firefox. Running version 3.6.10
Maybe an add-on update is required?

This review is for a previous version of the add-on (0.9).

Indeed, it does not work anymore; I believe this is a Firefox bug because copy-pasting tab character does not work either. I reported it as a bug at https://bugzilla.mozilla.org/show_bug.cgi?id=601497

Update: I checked and confirm that the problem goes away in the latest 3.6.11 nightly build.
