Stack Exchange in read-only mode

This userstyle aims to remove almost all interactivity with the Stack Exchange network for logged in users. Notably it leaves:

• Chat
• Following a post
• Saves

Removes most other features that produce visible feedback:

• Close voting
• Commenting
• Editing
• Flagging
• Posting
• Reviewing
• Starting a bounty
• Voting

This is done completely light-weight by using CSS to remove the elements. Notably, this means that keyboard shortcuts would still work. This is an accepted limitation - do not use keyboard shortcuts if you do not want to interact with the site. Or directly disable them.

You need a userstyle manager like Stylus:

• Stylus for Chrome - also works in Edge and Opera
• Stylus for Firefox
