According to examples, an apparatus may include a processor that may identify a navigation event responsive to a URL being entered into an address bar of a web browser, the URL having a domain and a URL component, and may determine whether the web browser received an instruction to navigate to a return URL, in which the return URL includes a suffix domain for a proxy and does not include the URL component. The processor may also, based on a determination that the web browser received the instruction to navigate to the return URL, generate a modified URL by appending the suffix domain to the URL to restore context of the URL for the proxy and navigate the web browser to the modified URL.
