Early 1990s

WorldWideWeb was the first browser for basic text pages.

Mid 1990s

Netscape Navigator and Internet Explorer became popular (browser wars).

Late 1990s–2000s

Browsers added non-standard features, causing inconsistency.

2000s–Today

W3C standards improved consistency and modern browsers now follow them more closely.

• Website Functionality Testing: Checks all features work correctly
• Usability Testing: Ensures the site is easy to use and navigate
• Security Testing: Protects user data and prevents attacks
