It appears that Mozilla does not intend to fix this version to be used under Windows 7. It continually and suddenly shows the Firefox version of the BSOD with GAH! at the top. I am in a difficult spot whereby I have several legacy programs I use in my business that do not work correctly under Window 10 or higher. I have tried Opera which is a solution other than it doesn't support an extension on Windows 7 for a mainstream program I use all the time. Please advise when you will get this bug fixed. At least provide older versions of Firefox when it used to work correctly.
