It also manages the interaction between the browser and the Document Object Model (DOM), allowing scripts and plugins to manipulate the content of a web page dynamically.
Given its critical role in the functioning of Internet Explorer, any errors or issues related to the mshtml.dll file can have a significant impact on the browsing experience. Common symptoms of mshtml.dll errors include browser crashes, slow loading of web pages, unresponsive tabs, and error messages stating that mshtml.dll is missing or not found.
