Created attachment 8500614 [details] thunderbird.png Entering a word, which can't be found in any mail, and the results-pane will have an unnecessary scrollbar. Adding a space and another string, and the scrollbar disappears. In Daily, there's no scrollbar, but a difference in vertical spacing. Thunderbird 31.1.2 Daily 2014-10-06
Does seem uncessary. Hopefully Richard can offer feedback
Created attachment 8643169 [details] Unbenannt.PNG On TB 38 I don't see it, maybe because the internal search is removed. Also when it presents only one email it expands correctly. But with TB 42 I see the scrollbar again The richlistitems had a CSS toolkit change to look more native on win10. It's not directly a CSS problem but I suppose it's a problem of the calculation of the height. Unfortunately I'm not the right person to find where this is calculated.
