The colour of an inbox no longer changes sufficiently (dark blue) from its normal colour (black) to be easily noticed. Is there a way to change this colour of the notification.

This can be done with a userChrome.css file:

/* Change the color of folders with unread messages */
treechildren::-moz-tree-cell-text(hasUnreadMessages-true)
{color: red !important;}

/* Change the color of folders with new messages */
treechildren::-moz-tree-cell-text(newMessages-true)
{ color: green ; font-weight: bold ; } 

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 above code, change the colors as desired. Double-click toolkit.legacyUserProfileCustomizations.stylesheets to true in Options/General/Config. editor, restart TB.

Many thanks. However I am using 78.4 (when these changes appeared) but cannt find toolkit.legacyUserProfileCustomizations.stylesheets in Options/General/Config

The pref. exists in profiles created by newer versions of TB, but if your profile was originally created by an older version, it may not be there. Right-click a blank area in Config. editor, New, Boolean, and name the pref. toolkit.legacyUserProfileCustomizations.stylesheets and give it the value true.
