PERFECT little extension for my use case, thanks! I make extensive use of filters on both my ISP's IMAP server (where I have messages pre-sorted into topical subfolders of my Inbox) and in Thunderbird (where I use filters to manually archive mail into sender-specific local folders).

BTW by "little extension" I mean that it's just a couple of kilobytes of JavaScript and JSON code that add an "Apply Filters" option to the bottom of the right-click context menu for folders and messages in Thunderbird. In fact the code is so brain-dead simple that I managed to tweak the context menu label more to my liking. Instead of generic "Apply Filters" labels I changed them to say "Run Filters on Folder" and "Run Filters on Message" for folders and messages respectively, using Thunderbird's own terminology (see "background.js" in the .xpi archive).

Message to Mozilla: Maybe this scary language: "This add-on can: Have full, unrestricted access to Thunderbird, and your computer" ... should be changed? I see nothing in the extension code that could possibly steal anything from my computer, or even from Thunderbird. It would be a shame if anyone passed up this extension due to this ominous language.

Message to everyone else: Give this extension a try. You'll save a lot of mousing up to and down the Tools menu (especially if you Run Filters manually a lot like I do), and your wrist will thank you.
