Works for me..

-Clicked the 'new reply' button.
-Clicked the 'choose file' button.
-Selected a file
-Clicked the 'add attachment' button
-The filename appears in the attachment list at the bottom.
-Clicked the 'insert into post' button.

This was on Chrome. But Im sure it also works on Firefox.
Otherwise you can use google photos to share pictures, almost everyone has a google account so that wouldnt be too difficult. You can create a share link on there that can be used in forums.
