#3541 closed defect (fixed)

Size of DOM Inspector dialogs is wrong first time they are opened

Review URL(s):



Adblock Plus 2.7.1 (started with Adblock Plus 2.7 according to user report), Firefox 43, Mac OS X 10.11

Also reproducible in Firefox 46.0a1 nightly with multi-process switched off (DOM Inspector doesn't support E10S).

How to reproduce

  1. Install DOM Inspector 2.0.16:
  2. On any web page go to menu Tools / Web Developer / DOM Inspector (alternatively you can customize your toolbar and drag the Web Developer menu into it).
  3. Press Cmd/Ctrl+F to open the Find Nodes dialog, dismiss it.
  4. Select an element and double-click an attribute in the right pane to edit it.

Observed behaviour

The dialogs open with buttons only, the content is missing. Second time they are opened correctly however.

Expected behaviour

The dialogs open correctly

I added a minimal extension to reproduce this issue without Adblock Plus. Turns out accessing document.documentElement from nsIContentPolicy.shouldLoad is sufficient to trigger this issue (content policy is called only once per session to check chrome://inspector/skin/inspector.css stylesheet).

  • Resolution set to invalid
  • Status changed from new to closed

This appears to be the same as - a platform issue, up to Mozilla to figure out what's going on here.
