I am using Firefox 54.0.1(64 bit) on macOS 10.12.6
We are running FileMaker server 16.0.2
I have a simple page, with 1 edit box and a button, when I paste some text into the edit box and click out of it, the last character of the pasted text disappears.
There are no Script triggers on the edit box, it displays data from a global storage field, which auto calculates with the following calculation - TextFormatRemove ( Self )
This behaviour does not occur when using Safari or Chrome.
