Firefox hangs on attempts to "Save as"

Posted

Firefox often hangs when I try to download files from the internet. This is independent of the directory to which I am saving (I have "ask me" enabled"). I have cleared the download history, but the problem persists. Typically, if I terminate Firefox during the hand and restart it (normally, not in safe mode), subsequent downloads are successful. The behavior is consistent over different websites and file types. I am using Firefox 71.0 under Windows 8.1 Pro x64. I don't have problems with "Save As" in any other application. There are reports of similar problems in Bugzilla and MozillaZine going back many years. I attempted to automatically add troubleshooting information, but got a message about missing a plugin instead, and lost all the text I had typed in here, so I have now added it manually.

The problem seems to occur when I haven't logged into my Firefox account. For example:

  1. if Firefox is not yet open and I try to download a file from a link in an e-mail
  2. if Firefox is already open, but I haven't yet entered my password in the pop-up login dialog
  3. if Firefox is already open and I have canceled the login dialog without logging in
The problem seems to occur when I haven't logged into my Firefox account. For example: # if Firefox is not yet open and I try to download a file from a link in an e-mail # if Firefox is already open, but I haven't yet entered my password in the pop-up login dialog # if Firefox is already open and I have canceled the login dialog without logging in

Thanks, but I was mistaken. I just experienced the problem again, *after* deleting my Firefox cache *and* logging into my Firefox account.
