Subtle changes, bugs and feedback

Updates on latest Firefox image uploading issue?

I have docs on the Files API https://developer.mozilla.org/en-US/docs/Web/API/File/Using_files_from_web_applications but need to weigh up whether fixing it will affect more people than not fixing it as https://caniuse.com/#feat=fileapi shows that UK usage is only 60% support it fully, and only 78% support it fully or partially.

In theory the % that do support it is all of the modern browsers, but in practice I bet a load of people are using old work computers to access this site.

Even after I've figured that out... I'd still need to write all of the code.

It will be a little while... the workaround is try to and attach twice, it works the 2nd time (twice before submitting the comment).
