PassIFox, firefox 42.0a2 KeePassHttp 1.8.4.0 KeePass 2.30

• Open a page with credential input fields (i.e. this)
• Right-click and select the menu item to enter redentials

Result: Firefox freezes. There is a tray notification that KeePassHttp is sending the credentials.

As @robertgzr figured out, probably it is important to note that this happens with e10 enabled. However, it does not happen on all the sites.

Same here: FF 42.0a2 with e10s passifox 1.1.13 MacPass 0.5.1 (keepasshttp-enabled fork)

switching to a non-e10s window everything works fine and as expected otherwise ff freezes and I have to restart
