Hello Firefox You are very good I use Firefox since a long time I wish that Firefox create an addon to enable us to colour every tab in a session where that colour of the tab can be saved for this single tab and we can change the colour of the tab according to our browsing meanings, because we tend to give the colours meanings so that we categorise the coloured tab in its place without changing the ordinary and usual user interface, that will make browsing more funny and productive, that's it

Thank you Firefox you are very good
