> Does this still reproduce for you? No. It has not occurred in recent memory. I had created an OS/X command file that increased the number of file handles before opening TB. That stopped the issue from occurring. I cannot say if the issue would arise again if I started TB normally. I had also mentioned "Message list settings were not saved when quitting" in the original post. That is still an issue. See [861747.](https://bugzilla.mozilla.org/show_bug.cgi?id=1861747).
