Hello all

Firefox is preventing certain websites from being diaplayed in the Tiddler.

For example, when I use the following code:

<html><div align="center"><iframe src="https://www.google.com"frameborder="0" width="100%" height="600"></iframe></div></html> ,

the message is get is :

Firefox Can’t Open This Page
To protect your security, www.google.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

Are there other options to get around this?

This is also happening when I use the weblinks to mythreadreader links compiling Twitter threads.

Thanks in advance

Manish

It is not Firefox that is blocking the use of an IFrame... the request is being refused by the source URL by returning an "X-Frame-Options" response header value of "DENY" or "SAMEORIGIN". This issue occurs in any browser. There is no general workaround. See https://stackoverflow.com/questions/6663244/cant-show-some-websites-in-iframe-tag
