Perform Responsive Design Testing

Responsive design testing helps ensure that your website correctly displays all content on a number of devices and differing screen sizes. Firefox uses the name Responsive Design Mode that shows different resolutions and orientations and allows one to see how an application behaves under various conditions of the display environment. Ensuring that your program is functional on desktop monitors and mobile devices is imperative. You can find the layout, navigation, and content display problems that may impact consumers on smaller displays or different devices by testing responsiveness.

Run Accessibility Audits

Performing accessibility audits is crucial to ensuring that those with impairments can utilize your web application. By checking your web pages for compliance with the Web Content Accessibility Guidelines (WCAG), tools like axe DevTools assist you in identifying accessibility concerns. These audits point out issues, including inadequate color contrast, missing alt text for photos, and navigational hurdles, and offer suggestions for fixing them. It is not only a great practice but also a legal requirement in many places to make sure your application complies with accessibility standards. 

Monitor Network Activity

It is essential to keep an eye on network activity while identifying problems with resource loading and server interactions. Firefox Developer Tools’ Network Monitor gives you comprehensive information about every network request your application makes, including image loads, script executions, and API calls. You can detect failed requests, slowly loading resources, and other network-related problems by looking at request and response times, headers, and status codes. Using this information, you can improve the speed of your application by resolving issues related to loading times and data transmission.

Conduct Security Testing

Identifying vulnerabilities in your web application requires security testing. Check your application for security flaws like missing security headers or incorrectly configured settings by using tools like the Mozilla Observatory.
