Rated 3 out of 5 stars

With TBBiff installed in both FF24 and TB24, and both running, the TBBiff tray icon in FF tray constantly shows that TB is off-line. Clicking on the off-line tray icon showing in FF does bring up TB display, but the off-line icon remains. Path to TB is correct.

This review is for a previous version of the add-on (2.4.1-signed.1-signed).
