Downloading GeckoFX older versions since Bitbucket repo turned private

Question

Since the bitbucket repo. of GeckoFX turned private, I am unable to download the older version of GeckoFX say 37.0.1 .

Is there any source or way to do it to get GeckoFX dlls from the Browser itself or I will stuck on this catch22 thing.

I really need to implement it an only with that version it is possible the thing

I need to achieve. I need to add a plugin built on XPCOM which i not a part of latest Firefox libs.

PS. I have searched zillions of articles and stckoverflow links but could not find any argument supporting my problem.

Answer 1

I don't think a 37.0.1 version ever existed but there was v33 + v45.

Softwareheritage has archived all the repos:

You can find the geckofx stuff here including the downloadable zip files.

The official source can be found here. Note this source contains tags for all the versions, so if you wanted to build v33, you would just update to the tag v33.0-0.10

Answer 2

Apart from Softwareheritage, you find some older pre-packed versions on nuget.
So, while you are able to fetch a earlier release of a specific package for your project using the package manager console in Visual Studio:

Install-Package GeckoFX -Version <press tab key for autocomplete> [*or a different package name]

you will probably not get far. Most of the GeckoFX releases on nuget are targeting more recent version (like v60, v45). But if you look a bit closer you will also find packages that are based on older releases like v33 (for winforms, and core).
