Change Developer Tools Responsive Design Mode default resolution

jab_creations

I'm a web developer and I've been using the web developer Responsive Design Mode for some testing.

Unfortunately the default resolution is 320x480 and while I do occasionally test this resolution (it's our bare minimal mobile resolution) it's obnoxious to have to always choose the drop down menu to change the resolution every-single-time!

I've already searched through about:config settings for queries such as 320 and 480 separately.

So: how do I change the Responsive Design Mode default resolution?

Your browser identified itself as Waterfox on a basis of an older version of Firefox, so this may or may not apply to you.

My Firefox always re-uses the last resolution. In about:config, I notice these preferences, which could be the way that happens:

  • devtools.responsive.userAgent
  • devtools.responsive.viewport.height
  • devtools.responsive.viewport.pixelRatio
  • devtools.responsive.viewport.width

Or maybe it's something in

[profile.folder]\storage\permanent\indexeddb+++fx-devtools\idb

Didn't you found these two prefs ?

  • devtools.responsive.viewport.height = 480
  • devtools.responsive.viewport.width = 320

@jscher2000 That works in Firefox however since they destroyed Firefox as of 57.0 I rarely test it.

I did a fairly thorough search of the Waterfox Classic files and I just can't find anything correlating to a preference let alone the DOM used for the Responsive Design Mode tool.
