The extension uses content scripts to modify the document title of each page. It also sets up a MutationObserver to maintain your prefix/suffix even when websites dynamically change their titles.

This extension requires the following permissions:

• tabs: To access and modify tab information
• storage: To save your prefix/suffix settings
• scripting: To inject scripts that modify tab titles
• host_permissions for all URLs: To modify titles on any website

• The extension cannot modify titles of browser internal pages (chrome://, vivaldi://, etc.)
• Some websites with complex title management might override the extension's changes
