In today’s fast-paced world, productivity tools and travel solutions need to be more than functional — they need to be intelligent, intuitive, and stress-reducing. Two standout innovations doing just that are Tree Style Tab, a Firefox extension by Piro (piro_or), and TruAirFare, a travel booking platform that’s changing the way people fly.

It's a good addon. I can't use firefox without it. However the recent update seems to be greying out some (but not all?) discarded tab favicons when I already have something to display that they've been discarded.
I tend to recognise tabs in part by favicon colour; is there a way to disable this behaviour? Nothing in the options for Tree Style Tab. Recent updates mentions some 'secret options' and I've no idea how to even access those.

Besides that, Tree Style Tabs sometimes loses the highlight of the active tab, and the only way you can identify it is mousing over all tabs and checking which one doesn't highlight.

I have a problem with the sidebar and creating new windows. It automatically disables the TST sidebar and it's somewhat annoying to press F1 each time I need to create a new window. Hope it's fixed soon or that there's a toggle option somewhere!

worked as advertised, but I didn't sign up for an "ai chatbot." such a feature frankly seems unnecessary, and should be left for extra extensions.
