Created attachment 8862372 [details] v52.png User Agent: Mozilla/5.0 (X11; FreeBSD amd64; rv:52.0) Gecko/20100101 Firefox/52.0 Build ID: 20170326074657 Steps to reproduce: Upgrade TB to v52. Actual results: Color at the heading of mail list area is white in v52 by mistake. Expected results: Color at the heading of mail list area should be gray as before so that one can distinguish from mails.
This is because FX and TB use GTK3 with version 52. Taka, please can you check, how the treeheaders in other GTK3 applications are looking?
Hi Richard, I've checked other GTK3 applications. I couldn't see any problem. For example, headers in Caja is fine as attached. Moreover, I found that even the headers in save dialog of TB v52 is fine. So, I see the problem only in the mail-list headers of TB v52. Now, I realized why I feel it very uncomfortable. There is no border line between headers and items. Perhaps, I chose wrong title for this bug...
Taka, please could you check in Firefox if the treeheader in the Library (All Bookmarks) look like the ones in TB? If yes, I'll move this bug to toolkit.
Hi Rechard, I've checked firefox v53 on my FreeBSD. Yes, treeheader in the Library looks same as one in mail list in TB. Its color is white (not gray) and there is no border line below, as attached. Please move this bug to tookit. I hope this will be solved before long.
Yes the headers are white on TB and FF. I thought we already have a bug for this.
