Technical details

• The popup the user interacts with is called "config", under popup/. It has an HTML and CSS file as you'd expect, defining the styles.
• config.js defines interactions with buttons on the config popup, and fires every time it is clicked to grab all current browser window tabs
• config.js requests the background script, scripts/background.js, to monitor the tab requested
• config.js also requests it to be removed, and handles all front-end mechanics for refreshing and updating the popup lists
• background.js is persistent as long as the addon is enabled, hence why it must be used to track timers and refresh/search tabs
• background.js receives messages to monitor tabs, stop monitoring them, and manages the timers with listeners
• background.js injects the content script scripts/content-script.js into the monitored tab when it is refreshed, and sounds the alarm/notification should results come
• content-script.js is responsible for searching for the string term/regex in the tab it is injected to. It must be done this way, because background.js cannot interact with the document in any tabs. It passes back its results to background.js.
