Unable to cannect with ASUS router after upgrade to Firefox 77.0.1
After upgrading from Firefox 76.0.1 to 77.0.1 on Windows 10, I am unable to connect with my Asus RT-AC68U router via the browser interface. When I attempt to login to the router, I get an error message "Invalid username or password". If I use Chrome version 83.0.4103.97, I am able to access the router without issue. I have tried Firefox in Safe Mode, but I still get the same error message. I have also tried resetting Firefox without any success.
I have another computer running Windows 10 with Firefox 76.0.1, so I confirmed that I could access the router with that version of Firefox and it worked fine. I updated Firefox on that machine to version 77.0.1 using the update button under Help/About and then tried connecting with the router again - it fails with the "Invalid username or password" error message. Again, I am able to connect using either Chrome or Edge browsers, but not with the latest version of Firefox.

The router is already running the latest firmware (version 3.0.0.4.385_20490-g57b06ea).
I found the problem to be that the password pasted from my password manager is 17 characters where the router password is limited to 16 characters. I noticed the issue by checking the "Show password" box when Firefox asks if I want it to save the password - the password shown was missing the last character. If I manually typed the password, the router would allow me to login. This problem manifested in Firefox 77 due to a new feature to truncate pasted text. Setting the Firefox parameter editor.truncate_user_pastes to TRUE fixes my issue (using a 16-character password on the router would also resolve the problem). The default value for editor.truncate_user_pastes is FALSE.
