FlashGot - Best Firefox Download Manager Integration - what is it? - InformAction

FlashGot gets your preferred download manager to work with Firefox! Download it now for free! - what is it?

flashgot.net

uGet is the only download manager I use, because it captures and successfully downloads
more files than all the others. Recently, I installed the latest version of uGet (2.2.3). For
some reason, FlashGot has problem detecting the latest version of uGet. It had no problems
with previous versions.

FlashGot provides a long list of grayed out managers. If you've installed any manager on
the list it should be automatically detected. uGet 2.2.3 was not detected, so I used the "Add"
button.

General Tab -> Add Button

After entering the name uGet, an error message appeared:

"Download Manager name is invalid or already in use!"

The final option that should convert the grayed out uGet to a functional listing is:

Advanced Tab -> Detect Now Button

All options failed. Why is this happening and how can I fix the problem?

FF has a built in feature and doesn't need an additional download app.

Corday, I understand that high speed internet service makes download managers
less important. I use managers with a script to automate downloads. If you read
my post, it's about FlashGot and uGet, not built-in download applets found in Firefox
and all other browsers.

SOLUTION:

The copy of uGet I downloaded and installed seemed to be functioning normally.
I extracted some of the critical uGet files from earlier versions and compared them
to the latest version. Files from old and new versions looked very similar, but there
were a few noticeable errors in the uGet 2.2.3 files. (I used an app that shows any
differences between two files that appear to be identical.)

Downloaded a fresh copy of uGet installer from:

Uninstalled the "damaged" copy of uGet and installed the copy from Github.
FlashGot instantly detected uGet. Problem solved.
