Makes the tab bars much less distracting. Thank you!

Works beautifully. Two suggestions:

1) The possibility to customize the level of desaturation;
2) The hability to desaturate tabs' titles as well (while being able to separetly customize the level for that as well).

Any chances we can get these, Tulirebane?

I don't know what happened but my favicons now resaturate. I've changed nothing and am not aware of any updates, but it works now and I really like this app.

Be careful when testing this extension! I was testing with the Mozilla Add-Ons page, which doesn't work with the extension. It works with everything else. My only problem is that tabs don't gain color when you go back on them, but I'm sure that'll be fixed and am anticipating that update.
No websites currently become recolored after I swap to them.
