Tor is one of the most popular anonymity networks that allows Internet users to hide their browsing activity. Hiding browsing activity is essential for Internet users to increase their privacy. Only Tor users should know the website they are browsing. However, an attacker can utilise the Website Fingerprinting (WF) attack to identify webpages browsed by Tor users. WF is a significant threat to Internet users' privacy as Tor should conceal the browsed webpages' information. Existing WF studies focused on the investigation to improve the identification capabilities, overlooking the systematic discussion and assessment of existing techniques. In addition, existing surveys and analyses reviewed insufficient variation of WF on Tor techniques. Therefore, this survey paper aims to provide a systematic and thorough review of various WF on Tor techniques. First, we discuss WF on Tor techniques in five primary aspects: threat model, victim target, website realm, traffic feature, and traffic clas-sifier. We analyse and classify the reviewed studies on each WF aspect. The classification facilitates in-depth understanding and comparison between WF on Tor techniques. Furthermore, this paper investigates nine as-sumptions exercised in WF on Tor: closed-world, sequential browsing, isolated traffic, replicability, traffic parsing, passive webpage, disabled cache, static content, and single webpage. These assumptions limit the WF on Tor's practicality in real-world scenarios. Our analysis and classification indicate that most WF on Tor studies apply these assumptions despite being only suitable in controlled environments or laboratory experiments. In addition, most reviewed studies often lack transparency on the assumptions exercised in their studies, risking misunderstanding the WF on Tor techniques' actual practicality. At the end of this survey, we present WF on Tor taxonomy and highlight 21 WF on Tor research's limitations and gaps with plausible recommendations. We also discuss the WF on Tor studies' contribution category and development phase.
