<p>Firefox 40.0 (40.0.2 update last Thursday) has been the current Release since Tuesday Aug 10. The Fx 39.0.3 was a last minute chemspill security update (for 39.0) the week before.

<p>Try to delete the MRU (Most Recently Used) ComDlg32 registry keys with the registry editor (regedit.exe).
Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32
Delete the subkeys (LastVisitedPidlMRU and OpenSavePidlMRU)
</p><p>Be cautious with editing the registry as there is no Undo possible: all changes are applied immediately.
You can export registry keys before making changes.

</p><p>Any download sites that uses Flash for Captcha and Ads on download page, make sure Flash is set to "Ask to Activate" at time. This alone can have a big impact on how smooth the download manager loads during the save, more so on a older lower spec system. Especially if you have had browser running for a while with a lot of downloads previously or currently going on.
</p><p>Doing the "Ask to Activate" on Flash helped hugely in download stuff on a old Linux box I had before system was taken down by PSU after a bad power outage.

And no, I don't open it during the download.
