I like the app, but it makes typing posts and comments into Facebook glacially slow.

Like another review noted, if you have the status bar displayed and print a page to PDF or paper, the status bar is included in the print. Removing a star for that.
Mozilla's page says it the extension hasn't been updated since 2019, although my Firefox addons list says 2023. Either way, not sure if anything will ever change.

Works fairly good with some failed downloads.

I've unchecked the box for playing a sound, so I don't get a sound on download, and it's not working

Yes

Really helpful add-on

one of the first firefox add on downloads

Works well for me (Firefox on macOS). The only reason not five stars is that if I download something, then print a page (to PDF), the status bar is included in the printout.

The chime when a download finishes is absolutely annoying and cannot be disabled...nice otherwise.
