Ciao a tutti
Potete dirmi come posso fare, o quale addon usare per poter visualizzare le mail in questo modo?
Intendo che si alternino una di un colore e una di un altro e così via, in modo che sia più facile la distinzione
Grazie mille
This is called zebra striping and can be applied to the Threads and Folder Panes with a userChrome.css file:

Help/Troubleshooting, Profile Folder, Open Folder, close TB, create a new folder named chrome, create a new document in chrome with a text editor, name it userChrome.css, Save as type: All files ., copy in the relevant code from the above links, change the numbers or colours as desired. Double-click ‘‘toolkit.legacyUserProfileCustomizations.stylesheets’’ to true in Options/General/Config. editor, restart TB.
Yes! It is what i said!
But how i put all that code in Thunderbird??? 
I’m not an expert man in code modifications
Thank you
