Description (last modified by kzar)


Firefox 59 / Windows 7

How to reproduce

  1. Navigate to
  2. Open the Adblock Plus devtools panel.
  3. Refresh page.
  4. Add the RuAdList+EasyList subscription.
  5. Refresh the page again.
  6. Close the devtools panel.
  7. Reopen the devtools panel and refresh the page.

Observed behaviour

The Adblock Plus devtools panel does not always seem to load correctly. Sometimes at Step 3 or 5, none of the requests are displayed in the panel. Nearly always at Step 7 the devtools panel is completely blank without even the filtering dropdowns displayed (see attached screenshot).

(The page is also blank after Step 5, but not sure if that is just filtering issues from RuAdList - See hub ticket 7906).

Expected behaviour

The Adblock Plus devtools panel to reliably load and display what is occuring with the page.

I can reproduce this, I suspect it's a bug with Firefox's WebExtension API. If that turns out to be the case we should close this issue and open one at instead.
