Hi all,
I prepared beta builds of the next Wine Gecko release. They are available via our new download site [1]. If you want to help testing, all that's needed is the attached patch (Wine will dowload the package for you).
This build is based on Firefox 44 sources. It includes a few Wine-specific bug fixes. Also the way we hook IO in Gecko is redesigned. The new interface should be more stable and the code is cleaner.
I think wine-staging may be a good way to have more testing before we do the final release. Please commit the patch to the tree.
Thanks, Jacek
