The problem is when I remove a silverlight application from the page in Internet Explorer, it actually starts up a new (invisible) version of the application. If your Silverlight app is big or gets data during startup, this means there is a delay where it seems like the browser isn't responding. Currently, the only major browser that continues to support Silverlight is Internet Explorer 11 for Windows 10. And even it will discontinue it by the end of 2021. The end of Silverlight.
As the web, and the technologies that drive it, have evolved, some of the early technologies that filled gaps are becoming obsolete. Internet Explorer used ActiveX to fill gaps with plugins like Flash and Silverlight. Modern browsers have already begun excluding these dated technologies as we approach the end of support life cycles. Modern, more secure, technology has moved in to take its place and end users need to prepare for the changes to come.
Here are the official statements of the respective companies:
Microsoft, on Silverlight 5, has announced the End of Life (EOL) through October 12, 2021, or the lifecycle of the underlying browsers, whichever is shorter. ( https://support.microsoft.com/en-us/help/4511036/silverlight-end-of-support )
Microsoft, on Internet Explorer 11, does not have an officially announced EOL date. They say they provide a minimum of five years of mainstream support, and an additional five of extended support for business. Internet Explorer 11 released Oct 17, 2013. This would imply that mainstream support ended Oct 17, 2018, and extended support would end Oct 17, 2023. Microsoft encourages the use of the Microsoft Edge browser and to limit use of IE11 to backwards compatibility only. ( https://support.microsoft.com/en-us/help/17454/lifecycle-faq-internet-explorer )
Adobe, on Adobe Flash, in collaboration with Apple, Facebook, Google, Microsoft, and Mozilla, is planning to EOL Flash. They intend to updating and distributing Flash Play at the end of 2020. They are encouraging content creators to migrate any existing Flash content to a new open format such as HTML5, WebGL, or WebAssembly. ( https://theblog.adobe.com/adobe-flash-update/ )
What does this mean to the end users?
End users should begin seeking alternatives to dated web applications that require Internet Explorer, Flash, or Silverlight to run. Once these products reach EOL they will no longer receive important security updates. This will ultimately lead to vulnerabilities on systems using these technologies.
End users who proactively move to modern browsers such as Microsoft Edge, Google Chrome, or Mozilla Firefox will be ahead of the change. However, they also need to find alternatives to dated technology or push to have those resources updated to modern open formats.

Compatibility Add-on for Chrome or Firefox
There is a free browser extension called 'IE Tab' that runs Windows Internet Explorer (IE) components within a tab in Chrome or Firefox. This enables you to display web pages that use Silverlight (such as CTI Navigator Web) within your Chrome or Firefox browser, even if the browser itself does not correctly load Silverlight. The IE Tab also includes an 'Auto URL' filter and a Bookmarks feature that allow you to specify which URLs should always be loaded with IE Tab.
Even though it does not open the IE browser per se, IE Tab uses the IE Browser Control core engine. Therefore, to ensure full security when using IE Tab, the latest version of Internet Explorer should be installed on your computer and it should be kept up-to-date with the latest security patches from Microsoft.
You can read about and download IE Tab at www.ietab.net.
