so good! Wish you could change the speed of the colour transition since its quite fast and would be so much better for people sensitive to light/people with epilepsy! :))

Great extension and idea.
Unfortunately, last update broke it for me and deleted all site lists (i.e. customisations), hence why not five stars. I'm not going to spend hours after every update just to recreate a experience which then just becomes lost.

me gustaria que se fucione con los otros temas que tenemos en firefox esta bonito pero si se fusiona con varias imagenes de los temas ejemplo estaba usando un tema de bleach, si se adapta esta funcionalidad manteniendo el diseño del tema que usaba anterior mente seria estupendo, gracias por el desarrollo le da otro rostro al navegador :D

This is so cool

How can we make zen browser also perfectly compatible?

feels very good but a little slow

Beautiful extension, unfortunately it keeps forgetting all of the custom/specific site list and colors after a few restarts, tried to only start the browser with admin previleges and got no results (Tried on both Firefox and Firefox developer edition, everything up to date from the date of this review, i have a few custom about:config's but only on the main Firefox app, so i guess theres nothing there that could be interfering).

EDIT: Going to test the new 2.4 extension version right now.

Interesting idea. Advanced settings are not as advanced as I would like for this to be actually usable. Time delay settings would be nice or a setting to wait until the tab is finished loading. Lots of false changes when the site is redirecting and flashing when it could be resolved by waiting a second. Turning off Dynamic Update of the tab color still sometimes has the tab color update, maybe when opening a new tab, but still distracting and against my wanted behavior. Amazing attempt, maybe Firefox's design disallows the true potential of this idea. I want a browser to do this seamlessly now.

Edit: appreciate the response!

I love this idea but I've had to disable it. On many sites I can't tell which tab is active. When you have many open its hard to hunt and peck when the highlight color is too similar to the rest of the theme.

The only disadvantage as for now is that when I type something in the search bar the first option is highlighted in bright blue. It would be nice to change that color as well.

Works very well but on some sites the color is slightly off.

Unfortunate oversight of the addon being that the bookmark overflow menu is not affected by the colour shift which makes the appearence of the browser ui inconsistent, which can be jarring. Would love to see this issue fixed.
