FYI AdBlock adding creating large emails on Microsoft Outlook webmail!

I use MS Outlook webmail at my company and people started complaining that an email with "test 123" was received as 418kb! A mail with say 500 characters was blowing up to like 1MB!

I disabled adblock (version updated 12/29/2015) or so (I use OSX 10.11.2) and all back to normal. I re-enabled and added my site to the whitelist in adblock and it's all back to the normal size.

    Hi Soames,

    This doesn't sound like something AdBlock could cause. Can you please remove the whitelist and try a couple of things to isolate the problem?

    First let's get some basic troubleshooting information. Please click the AdBlock button and select Options, then click SUPPORT. Next to "Have our team requested some debug info?" click here. Paste the text from the box into this discussion.

    1. Try updating your filter lists. Click the AdBlock button and select Options. On the FILTER LISTS tab click update now and then reload the page where you're seeing the problem. If the problem goes away, great, you're all done! You just had an outdated list. If the problem is still there, keep going.
    2. Next, try disabling all your filter lists. Uncheck all the lists on the "FILTER LISTS" page, then reload the page where you’re seeing the problem. If the problem goes away, great, we know it's one of the lists that's causing it.
    3. Now re-enable the lists one by one, reloading the page where you’re seeing the problem after each list is enabled. (Make sure to wait for AdBlock to fetch the list before reloading the page.) Which list causes the problem to happen again?
    4. Please report this to the list maintainers. You can find the contact info in our Knowledge Base.

    If unchecking all the filter lists did not fix the problem, try the same thing with your browser extensions: Disable all of them, then re-enable the extensions one by one, reloading the problem page after each. Which extension causes the problem to happen again?

    Let us know how it goes!

    Here is an email directly from my MS webmail account to yourself with Adblock enabled but my manual filters configured WITHOUT the URLs of my webmail client (ie you this email should be way larger than you expect).

    Hi Soames,

    Thank you for the debugging information. It will really help if you can try those troubleshooting suggestions I gave you. Here they are again for reference.

    1. First try updating your filter lists. Click the AdBlock button and select Options. On the FILTER LISTS tab click update now and then reload the page where you're seeing the problem. If the problem goes away, great, you're all done! You just had an outdated list. If the problem is still there, keep going.
    2. Next, try disabling all your filter lists. Uncheck all the lists on the "FILTER LISTS" page, then reload the page where you’re seeing the problem. If the problem goes away, great, we know it's one of the lists that's causing it.
    3. Now re-enable the lists one by one, reloading the page where you’re seeing the problem after each list is enabled. (Make sure to wait for AdBlock to fetch the list before reloading the page.) Which list causes the problem to happen again?
    4. Please report this to the list maintainers. You can find the contact info in our Knowledge Base.

    Please let us know how it goes!
