Since I upgraded to version 20 of Firefox I have found two (likely JS related) problems with Magento 126.96.36.199
The first is that the Insert Image Button in the admin via the WYSIWYG editor no longer works. Clicking on it has no effect at all. Works fine in other browsers though.
The second and most worrying is that I am unable to checkout. When I click the place order button a popup message says the payment has failed etc and it does not redirect me to Sagepay as it should. Again, this does not happen in Chrome or Safari. I use a mac so I’m not sure if this is also the case with FF on Windows.
However, a lot of mac users certainly use FF and if they are customers who cannot checkout because of this issue, it is a real problem for the store.
Anyone else encountered this? And more importantly, does anyone know how this might be resolved at the Magento side of things?
