Firefox dev tools: change JS execution context
Chrome dev tools allow to change javascript execution context.
It's very handy and I use it a lot in the debugging process.
But I need to test my project in Firefox and I can't find UI to change the execution context.
Does the Firefox has this feature?

Thanks for the link, but it doesn't helpful in my case. I want to execute a function in the extension's javascript context to trace current state. It seems impossible to do with Firefox dev tools. The only workaraound I see is to add a listener in the content to execute the required function and trigger the execution from the background scripts.

You should clarify in your question that you refer to extension development and not to website development.

The Firefox DevTools have the same feature, but you need to enable it first. To do so, open the Settings panel (e.g. by pressing F1), then check the option Select an iframe as the currently targeted document:
Once it's enabled, there is a new button at the upper right corner of the DevTools window:
Clicking this button opens a menu, which allows you to select the iframe. Hovering over the different entries even highlights the iframe or main document within the page to make it easier to identify them:
In contrast to the Chrome DevTools, this feature changes the context in all the panels, e.g. the Inspector will also be restricted to the document of the selected iframe.
(Note: The last screenshot shows Firefox 64.0, where the icon of the button and the layout of the menu changed.)

Thanks, Sebastian, for your detailed reply. If I get it correct, I can change js context for iFrames only. Is it possible to change js context for an add-on currently running in the browser?

I'm not much into Firefox add-on development these days, but if it doesn't work within the normal DevTools, it will probably work in the Browser Toolbox. That window looks basically the same as the normal DevTools but allows you to inspect everything within the browser context.
