#6744 closed defect (fixed)

An exception thrown from the `inject.preload.js`

Ubuntu xenial 16.04
Google Chrome Version 67.0.3396.79 (Official Build) (64-bit)
ABP v3.1

How to reproduce

I noticed this problem recently and I think it came together with v3.1 update.

inject.preload.js:373 GET blob: 0 ()

Steps to reproduce: open

It reproducible on basically every page.

It's not a 3rd party filters problem: reproducible with all filters disabled as well

I could successfully reproduce it on the other machine (windows). Exact steps there:

  1. Install the latest stable chrome
  2. Configure nothing go directly to the extension store and install adblock plus
  3. Open any page, eg
  4. See the chrome dev tools

I'm not sure what else I could do to help debugging it though

Ross and Rick, can either of you reproduce this? I couldn't so far.

It seems that, having an iframe on a page might be a necessary condition in order to reproduce it. There is a related stackoverflow question:

The last quote from this question makes me think that some recent changes to iframes in chrome might have broken the adblock.

Hopefully it's of any help to you.

  • Ready set

I reproduced it with Chrome 67 (previously I tried on Chrome 66 which doesn't appear to be affected). The problem appears to be that frames with a blob: URL (created by the extension) fail to load.

This bug is still present in

ABP 3.31.2
Chrome 67.0.3396.99 (64bit) / Windows 7 (ultimate)

Not sure if it is of any importance, but when i first enter a url the problems shows, if i refresh the problem is not there, and if i force reload the problem appears. So cache is involved in the problem (if it helps).

Hi, which url are you using/entering to reproduce? I've tried this again with the latest devbuild and Chrome 67 and cannot reproduce it.

comment:12 Changed 2 years ago by Eugene

From the screenshot and version numbers sent, it appears the error seen is from AdBlock and not Adblock Plus. Please contact the AdBlock support team for more insights.

Like Ross says this issue is for Adblock Plus not AdBlock, so for any AdBlock users please go to the AdBlock team for support.

I can't reproduce this in Adblock Plus any more since Sebastian's fix, in otherwords with development build

Like Trevor says the current stable version of Adblock Plus is 3.1, Sebastian's fix won't be included in the stable version of Adblock Plus until the next release which will be 3.2. There's no concrete release date so far as I know, once testing has finished we can begin preperations.

Thanks for the feedback everyone, sorry for the inconvenience.
