firefox w/o snap ubuntu 22

Snap sucks.  Firefox under snap sucks worse.  

Blocks access via links to local storage, which might seem useful, but is poorly executed with the snap solution.  

When updates are due, locks up firefox and forces a restart at the convenience of the update.  Again seldom happens at a good time.

Rather than install a down rev of ubuntu, the build with a deb install is available, no snap.

vnc security failure connecting to vncserver. desktop encryption setting

This seems to fix a problem connecting to Ubuntu.  Encryption is set to a level from other systems to work with vnc viewer, so can be disabled.  Might not be useful if not on a secure channel.  But tested and works.  This goes to the desktop software on the Ubuntu server machine.  

https://askubuntu.com/questions/1126714/vnc-viewer-unable-to-connect-encryption-issue

gsettings set org.gnome.Vino require-encryption false

Error message (or such)

Unable to connect to VNC Server using your chosen security setting.
