Where to find dTa xpi for download (manual install/update)

[Dibrom2]

Where may I find the releases of dTa (downThemall download manager) for offline manual installation please?
I have only recently found this source of the old v3 legacy dTa and installed it. The version I was given was dta v3.1.2.125.2024.03.18. This was working great, but then it automatically updated itself to v3.1.2.131.2024.09.12 and in the process of doing so, closed down, thereby cancelling some 7 active downloads, only some of which were from resumable servers.

To prevent this happening again, I would like to stop automatic app updates and only update manually when I decide it is safe and convenient to do so, but this obviously requires access to an archive of releases for dTa. Is there such a thing. Could someone please show me where the dTa releases are?

I've managed to pull the two versions below out of profile folders, but there must be a better way than doing that.
dta v3.1.2.125.2024.03.18-xiao.xpi
dta v3.1.2.131.2024.09.12-xiao.xpi

Follow up question:
The old-old v3 official release of dTa (specifically v3.0.8) had nice horizontal green progress bar graphs in the manager display that looked a lot like this:

The new version 3 dTa doesn't seemingly have these bar graphs, or else I can't find in the settings where to turn their display ON. Is there any way of getting the progress bar graphs back again?
