How can I tell if a site is built on Flash or Silverlight?

I use Lastpass (and have for years). I have a site I use frequently that won't fill the username and password, even when I try manually. I have to copy and paste them in. While looking for a solution in on the Lastpass support site I found a page that has the following sentence: "First check that... The site is not 'Flash' or 'Silverlight' - LastPass doesn't support these sites. Right-click on the site's login fields and look at the context menu information to check if the page is built on one of these platforms." My issue is that when I right click on either of the fields (username or pw) I don't know where to find the context menu information it is referring to. The closest thing I see is Inspect Element but when I click that all I see is a bunch of stuff that is WAY over my head. Can someone tell me how to determine the answer for this and other sites? This particular site is Wright Express (wexonline.com) if that helps. Thank you

Oh, thanks for the URL, I just noticed that. So that form is a little tricky. I'm attaching a screenshot of what you see if you right-click > Inspect element, and then put a little fake data into the form.

The page is copying what you type in the "password" field to a hidden field, and presumably the server uses the hidden field. I put "password" in quotation marks because unlike most sites, instead of using:

<input type="password">

This site uses:

<input type="text">

and a script in the page converts what you type to bullets.

This odd design may be confusing LastPass. Maybe send them information about the form and see what they can do.

Unless the site says they use Flash or Sliverlight you won't know til you go to the site and it informs you. Otherwise you can install Flash and Silverlight and if the sight uses it then it will run otherwise most times it won't run by default.

Firefox 58 doesn't run Silverlight, so if you see a login form, it's not Silverlight.

The Flash plugin has a distinctive context menu. When you right-click content displayed by the Flash plugin, you'll find a shorter-than-usual menu with some special items at the bottom specific to Flash.
