295989 - Download manager window is slow (5 secs) to open (cmd-j). opens on every download, and so every download is really slow to start.

Status: VERIFIED DUPLICATE of bug 240525

(Toolkit :: Downloads API, defect)

Description

[Roger Wagner]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

Using Mac OS X Tiger (10.4.1), immediately after starting Firefox, I do a cmd-J
to open the download manager window, and I notice that it takes 5 seconds (i.e.
really slow) for the window to open.

Reproducible: Always

Steps to Reproduce:
1. Startup Firefox
2. Press Cmd-J
3. 

Actual Results:  
5 second latency for window to appear.

Expected Results:  
Opened the window immediately.

  Since this window opens any time I save a web-page as an .html file, it means
that every file that I save has this big latency.  Why would opening just a list
of past downloads be so slow?  I checked the list, and eliminated any
"in-progress" downloads (which if present can send the time-to-open on this
window to 30-60 seconds).

Do you have a long list of downloads, if so try clearing the list.

If that fixes the problem then this is likely a dupe of bug 261885

The only method for "clearing the list" that I could find was clicking on
"Remove" after each item in the list.  With LOTS of past items in the list, and
truly 20-30  seconds of delay after each 'remove' command, it would have taken
hours.

So, I looked and found the file "downloads.rdf" in the Preferences file for
Firefox (in Library/Applications Support), and deleted the whole file.

This did indeed solve the big delay problem, but there should be (a) a way to
set the # of download items kept in the history and/or (b) a way to clear the
entire download history in one action.

You can select the clean up button at the bottom right, this clears all the
downloads from the list.
