Firefox 58.0.1 (not reproducible on Chrome)
Adblock Plus 3.0.0, 3.0.2 and ae47c9d78ac7 (current master)

How to reproduce

  1. Install/Reload Adblock Plus
  2. Open a new tab and go to
  3. Right-click the Google logo
  4. Select "Block element" from the context menu

Observed behaviour

A window with blank content opens up. I you close the window, reload the page, and try again, the window contains the "Block element" dialog with the suggested filter to add.

Expected behaviour

The "Block element" dialog should be working the first time, right after loading Adblock Plus.

I can now reproduce this behavior in chrome 65, do you mind checking this as well when you have a chance?

*never mind, if you refresh the extension and navigate to a tab which is already opened to the block element option does not appear; this is expected behavior

This doesn't reproduce every time for me. Maybe 50%? Right clicking in the window seems to redraw the content? I do see some error in the Browser Console, but I haven't verified yet if they are actually related.

Did something change? I can't reproduce this anymore.

I can still reproduce it 100% reliably, with Adblock Plus built from master (currently at 53853badc92) and Firefox 58.0.1, when I follow the exact steps from the issue description (most notably I can only reproduce it right after Adblock Plus was loaded).

Also right-clicking in the window correctly redraws the content for me.

Seems I am able to reproduce quite reliably know, pretty much every time and right clicking also redraws the window for me. Is there a way to get the window to update without right clicking as a work around?

Yea, I noticed that it would also redraw when I resized the window, and that we can do progmatically too.
