I am not a big fan of Tab Mix Plus (TMP) may be because I hear of so many issues it causes with Firefox. Yet it is by far one of the most popular add-ons for Firefox. Now comes word the latest version of TMP breaks the Add-ons Manager in the newly released Firefox 17. There is a work-around which involves installing a developmental version of TMP.
What I don’t understand is why are they just discovering this now? If this add-ons is so popular there should have been users who reported the issue during the Beta cycle in the past six-weeks, or even the Aurora cycle which started six-week before the Beta merge. I could even say the same during the Nightly cycle which was six-week before the Aurora merge, but Nightly releases are notorious for being buggy and having issues.
