Rated 5 out of 5 stars

Here, here. A fantastic add-on; probably my most used... Yes, I know FF 3.5.1 has a keyboard work around but that's not much use when my keyboard spends most of its time leaning against my sofa, not on my lap...
I've had compatibility issues with add-ons when upgrading FF previously; it's a shame FF doesn't seem to let me know about the add-on compatibility issues until after instalation...otherwise I probably wouldn't have upgraded yet, I'd have waited till the software runs and does what I want it to........+ the seemingly, randomly placed immovable "new tab" button...
