Bug: Finished DLs have incomplete %, won't clear

[gobias]

Download Statusbar has been working great until recently when all of the sudden a lot of downloads would be almost done at 97 or 98% and then freeze, or some would never even start. This is all in the Statusbar, though. If I check in Firefox's actual Downloads window, there would be nothing there, and if I open my Downloads folder the files would have finished downloading. Also, trying to pause, cancel, or clear these problem downloads does nothing. I have to restart Firefox to remove them from the Statusbar. Rather than just sitting at an inaccurate percentage, my last download still says Unknown for the file size, percentage, and time left. I just checked the Error Console, and found these errors with "downbar" in them:

Error: [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIDownloadManager.getDownload]" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: chrome://downbar/content/downbaroverlayNew.js :: _dlbar_setStateSpecific :: line 262" data: no]

Thank you so much for your help.

I have the same problem -- both on Mac (G4, OS 10.4.11) and PC (Windows XP).

I've recently installed BetterPrivacy, Cookie Culler and Tor -- could any of them be causing a conflict?
