Firefox compatibility problems

[stuxt]

I use bootstarp-wysihtml, Firefox browser in the input box input continuous spaces after or enter the number of words to certain length, use the backspace key, the input box will lose focus and need to click re input box to get the focus continued input. But that's normal in chrome.

My Firefox version is: 41.0.2
