How to more easily mark ALL messages as read in Thunderbird?
I don’t know of a way of marking all folders read with one command, but you can mark all the messages in a folder as read by either right-clicking the folder and selecting Mark Folder Read or selecting it and hitting Ctrl-Shift-C. There is an extension you might want to try: https://addons.mozilla.org/en-US/thunderbird/addon/2273 I think it just adds a button on the toolbar that does the same as Ctrl-Shift-C for a whole folder, but I’m not positive if it’s just one folder or all of them. Give it a try and see if it works better for you than what you’re doing. I hope this helps!!
