Rated 5 out of 5 stars

Firefox3 accompanied by HashColouredTabs, TabScope & Faviconized makes the best combination ever to me, who more often than not has >20 tabs opened at once. However, could you please make an import/export Hash list for visited sites, so that I can learn to recognize the color for my favorite domains and maintain the same set of colors in my office computer, home computer, college computer and my laptop. Thank you,

This review is for a previous version of the add-on (0.4.17). 

The generated colours are only based on the extension settings; However the original author made one setting (extensions.hashcolouredtabs.salt) random and hidden - it can be set from about:config so all profiles use the same value.

The saved colours and shapes are in the same database as, for example, zoom preferences and so import and export should be part of a more general solution - I don't think that there is a bug on this yet.
