MZLA Technologies Corporation (a subsidiary of the Mozilla Foundation) has issued version 138 of its free Thunderbird email and productivity app with over 20 improvements and bug fixes. The release updates the new mail alert to include message disposition buttons, adds a new mail notification customization to System Settings in macOS, improves message preview truncation in notifications, fixes a bug that caused incorrect message link and text colors when using Dark Reader, resolves an issue that prevented Newsgroups from being re-ordered in the folder tree via drag and drop, and addresses a crash that occurred when adaptive message filtering was enabled. (Free, 135.1 MB, release notes, macOS 10.15+)
I have relied on Thunderbird for years as it seems to be the only full-featured e-mail client still around (apart from Outlook). I have to say that in the efforts to update it (mostly very welcome btw), the number of bugs/misfeatures is growing rapidly.
For example, there is provision for playing a sound when a new mail arrives. I find this useful so set up Eudora’s sound. Until recently, this worked fine. Lately though, the sound plays but no new mail is visible.
It is hard to prove, but I suspect that it is playing when only spam has been received, ie, no new mail that I am interested in. Older versions did not do this.
It also will play multiple times when you have several accounts checking at the same time. This is silly. If it is checking multiple accounts, it should wait to play the sound until all are finished.
