📚 Glossary

User-Agent: An identification string your browser sends to web servers. Contains OS and browser type/version information.
Screen Resolution: The number of pixels on your display. Important for verifying responsive design behavior.
Device Pixel Ratio: The number of physical pixels per CSS pixel. Retina displays have a ratio of 2 or higher.
Cookie: Small pieces of data stored by websites in your browser. Used for session management and tracking.
WebGL: An API for rendering 3D graphics in browsers. Support status determines whether 3D content can be displayed.
OS (Operating System): The foundational software running your device — Windows 11, macOS, iOS (iPhone), Android, etc. Essential for isolating bugs that occur only on specific OS (e.g., buttons unresponsive only on iPhone, wrong font on Mac).
Browser & Version: Software for browsing the internet — Google Chrome, Safari, Edge, etc. Older versions may not support modern website features, which is why both name and version are checked together.
IP Address: Your "address" on the internet. Helpful for diagnosing network issues like "can only be accessed from the office network" (firewall blocks).
Screen Resolution & Window Size: "Screen Resolution" is the monitor's total pixel count. "Window Size" is the actual area where the browser is displayed. Needed to identify issues that only occur on narrow screens like smartphones.
Cookie: A browser feature that remembers login status and shopping cart contents. If cookies are "disabled" due to strict security software, critical issues like repeated login failures or empty carts can occur.
JavaScript: A programming language that handles dynamic operations on websites like menu toggling and animations. Most modern websites won't function properly with JavaScript disabled.
Color Depth & Pixel Ratio: Information about how many colors your display can render and high-density pixel displays (like Apple's Retina). Referenced when investigating reports like "photos look blurry" or "colors seem wrong."
User-Agent (Raw Identification): The identification string your browser sends to web servers. Support teams can use this string to emulate your environment on their own computers for testing.
Estimated Network Speed: An indicator of what generation network speed your browser estimates based on actual speed and latency. Due to browser specifications, "4G" is the maximum value, so fiber Wi-Fi and 5G also show as "4G equivalent." Used to check if the customer's connection speed has drastically dropped when they report "the site is slow."
