I see this too with Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9b3pre) Gecko/2007121304 Minefield/3.0b3pre; not sure when this regressed.

(It's going to take me a while to find out, but according to tomcat's past test, this last passed on 10/28/2007: https://litmus.mozilla.org/show_test.cgi?id=4718.)

I get a regression range of between 2007-10-01 and 2007-10-02:

There is a whole bunch of download manager related check-ins.
Regression from bug 393821? Or bug 382388?

Thanks for the regression window. It's bug 382388.

WebBrowserPersist is giving us a status code 0x804B0002 (2152398850) NS_BINDING_ABORTED.

This only shows up if you save the local file to the same location. If you save a local file to a different file (for web pages or single files), there's no problem.

I guess WBP doesn't like overwriting the file it's reading..

WBP issue? dlmgr issue? dlmgr work around? Ignore some error codes?

Not blocking as this is pretty edge-case-y ...

If I follow the steps from the testcase using any page, I get a confirmation prompt informing me that the page already exist and asks if I want to replace it, which seems to be the expected behavior. Considering this I will close the bug as WFM.
