Hi, its been a while since I posted anything on here. Below is the content of my userChrome.css

@namespace url( ... s.only.xul);
/* Message header colour (Message header colour - found via gimp programme – TB2 colour = #d3daed) */
#msgHeaderView {background-color: #d3daed !important;}

/* Message header line height */
.headerValue {line-height: 1.00em !important;}

/* Account name label & Inbox label stay black */
treechildren::-moz-tree-cell-text(folderNameCol, isServer-true) {color: Black !important;}
treechildren::-moz-tree-cell-text(folderNameCol, newMessages-true) {color: Black !important;}

/* Hide white bar top of screen win 10 */

/* Add Back Asterisk on Folder Icons */
treechildren::-moz-tree-image(folderNameCol, newMessages-true) {-moz-image-region: rect(16px 16px 32px 0) !important;}
treechildren::-moz-tree-image(folderNameCol, selected, open, newMessages-true) {-moz-image-region: rect(16px 32px 32px 16px) !important;}
treechildren::-moz-tree-image(folderNameCol, specialFolder-Inbox, newMessages-true) {-moz-image-region: rect(16px 48px 32px 32px) !important;}
treechildren::-moz-tree-image(folderNameCol, specialFolder-Virtual, newMessages-true) {-moz-image-region: rect(16px 176px 32px 160px) !important;}

/* Folder pane(color/text) and Message pane(color) */
treechildren {background-color: #d3daed !important;}

/* Toolbar background colour - Menu bar, folder pane, mail toolbar. */
toolbar {background: #d3daed !important;}

/* Removes date field from Message header */
#dateValueBox {display: none}
#header-view-toolbox, #otherActionsBox {display: none !important;}
#expandedHeaderRows {padding-top: 0px !important;}

/* Remove stars beside new email in subject column */
.emailStar {display: none !important;}

/*Horizontal lines between messages */
#threadTree treechildren:-moz-tree-row {border-bottom: 1px solid threedlightshadow !important;}

/* Add zebra striping, Safe with noglass extension installed */
#threadTree > treechildren::-moz-tree-row(odd) {background-color: rgb(255,255,255) !important;}
#threadTree > treechildren::-moz-tree-row(even) {background-color: rgb(246,248,249) !important;}

With Thunderbird 45 & two or more tabs open I get a noticeable line between top of tabs & where the main toolbar buttons are (write / reply / delete junk etc.). The guilty code is below, I am sure its this as I have taken out the entire content of userChrome.css & gradually restored / saved the file & restarted thunderbird after each. Disabling add-ons makes no difference, tried default theme as well no dice.

Guilty code:
toolbar {background: #d3daed !important;}

Now the questions:
Anyone know why the above code generates a gap with two tabs or more open & how to tweak it whilst still having both tabs open?
Is there anyway to hide the white bar at top of screen?
Any way to shift the tabs over to left so they line up with edge of screen.
Cant find / interpret it with dom inspector.
