A few bugs but still good Rated 4 out of 5 stars

This is a giant leap forward because it allows so much more user input into how it operates (e.g., repositioning the alerts). Maybe it\'s just with my elderly Win98SE, but the main minus I\'ve encountered, but got around by sheer persistence: add-on does not seem to retain changes to its settings. Most often, it goes right back to original choices next time Tbird opens; sometimes the problem is an uglier bug - settings come up totally blank when the settings window is accessed, even though the alert itself still operates. Uninstalling and reopening Tbird to verify that the folder list\'s context menu item for Mailbox Alert is indeed gone produces a big surprise when you subsequently reinstall Mailbox Alert: those settings you were trying to get rid of? Still there! Annoying. Eventually, just by repetition, my \'edits\' have been enacted. \r\n\r\nHere\'s a tip, something I basically forced into existence: among the settings you can choose the icon that will appear in all alert boxes. On a hunch I edited an abstract-looking icon to be double the typical icon\'s size (so it\'s 64x64 pixels) and used this new mega-icon. Now the alert box is *much* bigger, with a generous in-your-face square of color I can spot from across the room. Hurray, my wish come true.

This review is for a previous version of the add-on (0.13.1).
