TLDR: The gnome keyring daemon is causing authenticated web pages to not load. Kill the gnome-keyring-daemon process for a fast fix (sudo killall gnome-keyring-daemon). See below about how to keep this from happening.
If you are trying to login to websites on Chrome on a Linux desktop, and your browser freezes after clicking the login button, the Gnome keyring might be the cause of your agony.
On Linux, when Chrome loads a web page where credentials are involved, it seems there is a hook in the Gnome desktop software, where if Gnome keyring is turned on, it will try to save your credentials before allowing the web page to load in Chrome. Unfortunately, if the box for this does not pop up, or the pop up window is buried behind other windows, it looks like your Chrome web page (likely Firefox as well, but I have not checked) just freezes and it will not respond to any input at all.
For a fast fix you have to kill the gnome-keyring-daemon process. Usually it's just "sudo killall gnome-keyring-daemon". It might be called something else on your machine. I suggest looking for something with "keyring" in then name. After killing it your pages should load as expected. But your wondering how do you keep this from happening again?
To keep Gnome keyring from doing this to you again you can try a few things.
First thing to try is turning off the Gnome keyring daemon, if you are not going to use it. The daemon is used to store credentials like ssh keys or passwords for you. If you know your not going to use it just turn it off. Usually on different desktops there is a area in the settings that will show you what things run on desktop startup. You will have to find that for your Linux desktop distro (there are to many ways for to many desktops to list here), and see if Gnome keyring daemon is there. Then uncheck a box to turn it off. The logout and log back in.
The second way to handle this is to leave the keyring daemon on, and just set a blank password (insecure yes, but if you are not going to use it then who cares). For an example on how to do this in the MATE desktop you go to Applications -> accessories -> passwords and keys. Delete the "Default" Keyring that has the lock symbol. Close your browser and open it back up. Go to a web page that requires a login, and try to login. Gnome keyring should now ask you to choose a new password. Don't enter a password, and click the ok button. It will warn about credentials being unencrypted, but that is ok if your not going to put things in it. This will now keep it from opening again in the future.
