Build ID: 20180704194937

Steps to reproduce:

i open a url with a login form.
i clicked in the username field and typed my username.
i clicked tab to switch the focus.
i type my password in the field. (My password contains the char '@')
If i typed the '@' char, the input will complete marked and with the next char it will be overwritten.


i have tested all firefox versions at ubuntu 16.04 64bit.
at windows 10 64bit this bug is not present.

i have tested with my nextcloud and grafana homepage:
https://cloud.elaon.de
https://monitor.elaon.de


Actual results:

with the '@' char all text in the input will marked and overwritten.
if i clicked in the input field, than this bug will not occur.


Expected results:

i can type my password with the '@' in it, without marked all text and overwrite it.

I have tested this report on Windows 10 x64, Ubuntu 18.04 & 16.04 x64 using the latest Nightly and Firefox release build. I did not manage to reproduce the mentioned behavior. I have tested with different pages like Twitter, Grafana, GitHub, Youtube, and Facebook. I`m not able to mark nor overwrite my password that contains '@' char when I`m tabbing to change the focus or when clicking in the password field.

Can you re-test this using a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause?
Do you have any add-ons installed to the browser you are using? 

Please change if this is not the correct component.
