I've been downloading things in the browser from images, .doc's, ppt's, and
pdf's.  I've been using it for a while.  Nowadays, when I want to download an
image, the browser pauses for about 10 seconds.  I created a new profile and I
don't experience this slowdown.  I've tried to clear the cache but this did
nothing.  I think it might be the download manager.  

Reproducible: Always

Steps to Reproduce:
1.  right click on an image.
2.  Select Save Image.
3.  Select a location to save.
This is when I experience the pause.
4.  Open download manager.
5.  select all the items in the list (I have about 1000+ items).
6.  Click "Remove from List" Button.
Completely lock out.  I have to go to task manager to end the program.

Actual Results:  
See above.

Expected Results:  
After step 3, I should not have experienced a pause.
After step 6, the download manager and mozilla should not have frozen.  I should
be able to select every item listed in the download manager and click remove
list.  As is is, I have to highlight no more than 10 items at a time.

workaround: 
Close Mozilla, delete downloads.rdf in your profile. An empty file will be
recreated at next start of Mozilla.

Bug 159107 page saving takes too much time ('marooned' entries in downloads.rdf)
