This bachelor thesis deals with the comparison of various web browsers in the terms of their impact on users‘ privacy while browsing the web. There are two objectives defined in this thesis. The first objective is the execution of a questionnaire survey designed to find out respondents’ awareness of the impacts of web browsing on their privacy online and the use of specialized tools to protect that privacy. The second objective is the selection of web browsers to be analyzed and to compare those in terms of their impact on users’ online privacy, where the criteria of selection are influenced by the results of the first objective.The theoretical part of this thesis focuses on the means through which tracking of users’ internet activity can be achieved, the reasons for such actions, and the possibilities of use or misuse of such tracking and the data compiled from it. The practical part of this thesis first deals with the definition, execution, and evaluation of the questionnaire survey, where the results are used to modify the criteria for the selection of six web browsers to be analyzed with tools designed to detect the possibilities of tracking the users’ internet activity.The main benefit of this thesis is to improve the insight into the given web browsers in terms of online privacy protection. Out of the six browsers two are generic popular user choices, and four are lesser-known specialized browsers designed to maintain a higher level of users’ online privacy protection. It can be ascertained from the test results where the advantages of these specialized browsers lie in comparison to the generic choices, and to what extent these browsers fulfill their claims about their functionality.
