Hi Eric, 

I'm sorry you're having an issue in Firefox. I am trying to reproduce this in nightly, and I am unable to. 

Some things I would check next:

* Does responsive design mode work in other sites?
* If you load the same file, but from a web server does it work?
* Does the page depend on JavaScript to work?
  * If the paths to the javascript files are hard-coded, i.e. "/public/javascript/script.js", instead of relative, i.e. "public/javascript/script.js"
  * Does the site depend on a server to provide data and the server is not available locally?

If those do not work, would you attach the file, or a reduced case of the file, without personal or confidential information, to this bug.

Thank you.

Hi Emma,
No apologies needed; you all make the best browser on the market. Also, the update to 65.0b2 (Dev Edition) seems to have addressed the error. In response to the scenarios you posited when I was using yesterday:

* Yes!
* Yes, loaded from the server it worked.
* The page is progressively enhanced with JS but it is not a dependency for load.
* All the pathing is relative
* No external dependency. The site is really just 2 static HTML pages with some css and js... exciting stuff.

Since this is client work, I can't provide source files but I can say, again, that the nightly build seems to have caught the error.

I have similar problem.
Version: Firefox Developer Edition 65.0b4 (64-bit). Windows 10 Professional.
Responsive Desing Mode often freeze. 
Everyfing works fine, but the viewport area is freezed.
Screen show actual view, and do not change after page refresh.
Solution is I have to disable and enable Responsive Desing Mode. But this is very confused tiring.
It happend on different websites, servers.
I tryed enable / disable hardware acceleration, but this not help.
