Web Browser Extension for Web Page Analysis
Novotný, Jakub ; Zaklová, Kristýna (referee) ; Burget, Radek (advisor)
The goal of this project is to create a browser extension that will use the WebExtensions API technology to analyze and process data from dynamically changing web pages. The extension collects data, which it sends in JSON format to the server, where it will be processed. Subsequently, the results are returned to the extension and presented to the user either as text output or visually as an overlay on the page. Thanks to using the WebExtensions API, the extension is compatible with a wide range of web browsers.

Native Code Web Browser Extensions
Vítek, Vojtěch ; Očenášek, Pavel (referee) ; Burget, Radek (advisor)
Nowadays, web applications and browsers are undergoing rapid development - we can say that the progress of Internet technologies is unstoppable phenomenon of the last decade. The need for the best-possible CPU performance in web applications to achieve a smooth user experience is enormous - besides the continuous improvements of existing technologies, we can see several new technologies arising every year. This thesis deals with development of native code web browser extensions whose primary purpose is to use maximum CPU performance as well as efforts to improve the user experience when viewing web pages.

Optimizing JShelter Performance
Zmitko, Martin ; Polčák, Libor (referee) ; Hranický, Radek (advisor)
This thesis aims to lessen the impact of JShelter on the browsing experience. The goal was accomplished by measuring the performance of JShelter and analyzing the hotspots that impacted browsing performance the most. Finally, optimizations based on analysis results while leaving the high provided level of protection uncompromised were proposed and implemented. JShelter's fingerprinting protections based on image and audio data processing were optimized by extending them with a more efficient implementation using WebAssembly, which, in some cases, was faster by up to 50 times. The performance while loading web pages was increased with changes in configuration loading and injection mechanisms, on average by 13.5 %.
