The latest report failed to be upkoaded...

And I forgot to mention, that I have aready uninstalled Firefox and reinstalled a fresh installer download (using Chrome!!!).

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Bug 1662317 About Throttling My Firefox crashed but did not submit the crash report.

I tried to manually send the report, and the system gave me the message: About Throttling

If Mozilla does not need the report, I, the user, still want to know what happened. How else can I fix or understand what went wrong?

Safe mode did not help. I did not mention that, but of course I had tried that earlier, it's the first thing to do when something goes wrong... I repeated it now: browser stil disappears silently after attempt to navigate to target folder for a download.

I tend to think that I should uninstall Firefox and clean the register from remnants of it before reinstalling. Would that be a logical step to perform?

(I will also try to find a Microsoft forum on details of File Explorer failing to do it's job under Firefox :-) )

Let’s do a full clean re-install;

Note: Firefox comes in three or more folders on all computers. They are;

Maintenance: (Programs Folder) <Windows Only> Firefox itself: (Programs Folder) And two folders in the profile of each user on the computer for each Firefox profile for that user.

If you remove the Firefox folder, the user profiles would not be affected.

Download Firefox For All languages And Systems {web link}

Save the file. Then Close Firefox.

Using your file browser, open the Programs Folder on your computer.

Mac: Open the "Applications" folder. https://support.mozilla.org/en-US/kb/how-download-and-install-firefox-mac

If you downloaded and installed the binary package from the Firefox download page, simply remove the folder Firefox in your home directory. http://www.mozilla.org/firefox#desktop ++++++++++++++++++++++++++++ Look for, and remove any Mozilla or Firefox program folders. Do not remove the Mozilla Thunderbird folder if there is one.

Do Not remove any profile folders.

After rebooting the computer, run a registry scanner if you have one. Then run the installer. +++++++++++++++++++++++++++ If there is a problem, start your Computer in safe mode and try again.

Yesterday I did as instructed, and I could save a download in the desired folder again. But today , after shutdown and this morning a restart, situation is restored: I can't save a download. What on earth...

I called for more help.

Maybe call again? :-)

As a workaround, for downloads I now use a fixed folder, and move files from that folder to their destiny. But I now have to upload files very frequently, and there is no workaround for pointing to the file. Firefox is now unusable HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Have you tried using upload/download managers?

No. Never had any need of a download manager. I never upload or download huge files. I would not even know how to install one.

Go to the Mozilla Add-ons Web Page {web Link} (There’s a lot of good stuff here) and search for what you want.
