Reinstate connecting lines in thread pane for threads.

[Toad-Hall]

If using Sort by > Threaded :

Then thread pane is missing the connecting lines. 

Problem - This can make it difficult to figure out indentation with bare eye for deep and long threads.

If possible perhaps set up as a user preference. Enable/disable converation hierarchy lines.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

I like the idea.  Even if TB 102 didn't have them, I was able to expand the lines with CSS.

I like the idea too! 

My CSS didn't work for me!

Any attempt now that I've seen also does not work in 128.

I did get this code and tried it, no go.  But the user said it worked on his MAC.  You can give it a try in the userChrome.css, obviously use any color that fits you theme.

#threadTree treechildren::-moz-tree-line { visibility: visible !important; }
#threadTree treechildren::-moz-tree-line(selected, focus) { border-color: #FFFFFF !important; }
