I found this info on the Firefox Builds board on mozillaZine. Some of you may recall from Firefox 1.5.0.* builds the download manager would keep a history of your downloads. By default it would retain this history until you choose to clear the list or if you changed the settings via a menu option.
Due to possible performance issues associated with having long download list, Firefox 2 by default clears the list as soon as the download is completed. You can change this option by going to Tools -> Options -> Privacy and checking Remember what I’ve downloaded. However there is a third option to retain the list until the browser exits, but this can only be set via an about:config entry:
- Click the about:config button (if you have the extension) or open a new tab and type about:config in the address bar
- In the filter field enter browser.download.manager.retention
- double-click on the entry and enter the corresponding number below:
- 0 ~ List clears when download is completed
- 1 ~ List clears when you exit the browser
- 2 ~ List clears only via ‘Clean Up’ button
- Click OK
- Close about:config editor or tab
Keep in mind the “performance issues” were NOT fixed so the change in the default behavior for the download manger was only a band aid.
The issue I am having is that when I click the “clean up” button (in FireFox 2.0) it only removes one download at a time – usually the most recent download first. Before the update it use to remove ALL completed downloads. I have tried searching for this, but to no avail, as it seems nobody else is having this issue, or is not reporting it. I also tried many tweaks and such to my preferences; still to no solution.
I am running Mac OS x 3.9
I have some management and download extensions that I thought might be the culprit, but I’d like an opinion before removing them;
Download Statusbar 0.9.4.5.1
Ook? Video Ook! 0.6.5
Session Manager 0.5.3.2 (disabled)
Tab Mix Plus 0.3.5.2
send me download entention software
I was also getting this problem, and I have found a way to fix it (for me atleast). I am running a FireFox extension called ‘Download Status Bar’ which keeps it’s own list of files that I have downloaded. This had almost 150 entries in it, and I found that once I cleaned them out, this enabled the clean up button to do its job and remove all entries from the standard Firefox dialouge.
I don’t know is will help, but I know how frustrating it is to search and search, and not find anything.
