Load iframe only when needed

[sahithyandev]

The iframe I am talking about is the sidebar that appears when the extension is activated (by clicking the icon).

Currently, the extension creates and loads an iframe for each tab on load. However the iframe is only shown after the user activates the extension. This causes unwanted resource usage (CPU and RAM) for users.

I suggest we only create the iframe when the extension is activated.
This might cause longer response times to show the iframe. I don't think it will be notable though. Will update if I measure it.

@sahithyandev Can explore. Unless u think it will have significant impact on performance, ignore this.
Assume even low end PCs for our users.

I did notice a little performance issue on particular websites while I was using. This is very low in priority though.
