Be careful with old versions!
These versions are displayed for reference and testing purposes. You should always use the latest version of an add-on.
(*) Improved UI behavior
(*) Improved performance a bit
(*) Now supports Firefox version 52.* as well
(*) Blue Flash icon shows up again
Due to the nature of "WebExtensions", which is the new way (and only way, starting Firefox 57) to develop Firefox Add-ons, the integration of this Add-on with the "DownThemAll!" Add-on for downloading files, had to go away for a couple of reasons, but mainly because "DownThemAll" is not compatible with Firefox 57 at the moment.
If anything changes on that aspect, the integration may be added again.
Thanks and sorry for the inconvenience.
(A WebExtension (Firefox +57) version is coming soon!)
