Start with the symptom.
Understand likely causes, run the right browser-based check, and try low-risk fixes before making bigger changes.
Performance and browser
Slowdowns, memory, tab crashes, and web storage
Why is my computer running slow?
Separate browser limitations from wider device performance problems before changing hardware or reinstalling software.
Open guideWhy is my browser running slow?
Identify whether extensions, tab load, storage, graphics acceleration, or the network is making browsing feel sluggish.
Open guideWhy is my browser using so much memory?
Separate normal tab isolation from extensions, runaway pages, memory pressure, and a damaged browser profile.
Open guideWhy do browser tabs keep crashing?
Find out whether crashes follow a specific website, extension, graphics path, profile, or system resource limit.
Open guideBrowser storage is full or unavailable
Understand browser quota, site data, private-mode restrictions, and why free disk space is not the same as web storage availability.
Open guideService Worker is not supported here
Check whether the browser, secure context, embedded view, or site configuration is preventing offline and installable web-app features.
Open guideDisplay, graphics, and input
WebGL, acceleration, mouse, and touchscreen problems
WebGL is not supported or unavailable
Understand why WebGL may be missing and verify whether the browser can complete a controlled graphics render.
Open guideBrowser hardware acceleration may be disabled
Check for software graphics fallback and restore GPU-backed rendering without treating a renderer string as absolute proof.
Open guideMouse clicks or movement not working
Separate a browser or application mapping problem from wireless, sensor, button, cable, port, and operating-system causes.
Open guideTouchscreen not responding in some areas
Check repeatable missed regions, interrupted gestures, protectors, moisture, software overlays, and possible digitizer faults.
Open guideCamera, microphone, and calls
Media permissions, device selection, and WebRTC connections
Camera not working in the browser
Check browser and operating-system permissions, select the intended camera, and preview it locally without uploading or recording the image.
Open guideMicrophone not working in the browser
Distinguish permission denial, a missing input device, another app using the microphone, and low input level.
Open guideWebRTC connection failed in the browser
Separate a missing browser engine from media permissions, firewall policy, VPN routing, TURN relay, and service-specific failures.
Open guideNetwork and internet
Ping, speed, request loss, and Wi-Fi disconnects
Why is my ping high?
Measure browser-to-server response time and separate Wi-Fi instability, routing distance, VPN overhead, and local congestion.
Open guideWhy is my internet slow?
Use transparent transfer measurements and repeatable comparisons before blaming the browser, router, or ISP.
Open guideHow to investigate packet loss
Use repeated HTTPS samples as an initial signal, then confirm the affected route with tools designed for the application or network layer.
Open guideWhy does Wi-Fi keep disconnecting?
Determine whether the interruption follows one device, one access point, one room, or the wider internet connection.
