    Just updated I guess (10/31/18), and now have to refresh to make changes from on to off? Used to be able to turn off to load certain pages, then turn back on once loaded. Now, it does not work at all. If you refresh the page with it on, after loading it with abp off, it detects and will not reload the page.

    Reply from Thomas Greiner:

    Does this also occur on other websites and/or using a different browser? Because ad blocker detections that websites use are generally quite unreliable since they don’t detect ad blockers directly. Furthermore, they may not check for it again after reloading the page.

    If you can reliably reproduce this issue, it’d be great if you could report it at so that we can have a closer look at it.

    Update: The behavior as it was in the old version remains unchanged so en-/disabling the extension without clicking on "Refresh" should have the same effect as before. We are currently discussing how we can make it clearer that clicking on "Refresh" is not mandatory (see issue 7092) so we'd be happy to hear from anyone who wants to see this improved.

    I suddenly found on Firefox 52.9 ESR on my old Windows XP machine that Facebook had become virtually unusable. Extremely slow and kept locking up, and Firefox kept popping up messages about unresponsive scripts. If the script was stopped all immediately returned to normal, but failed again on going to a new Facebook page.
    After a lot of head scratching, I discovered that ABP was the cause, and I’ve had to disable it on Facebook. The problem I’m sure started when ABP updated to 3.4 in the background without me being aware of it. My Windows 10 machine with Firefox 63 shows no such problems. Cheers, Dave.

    Reply from Thomas Greiner:

    Thanks for reporting the issue. We got another user who experiences a similar issue on Firefox and Windows XP but using Adblock Plus 3.3.

    Therefore our assumption is that this issue was not introduced with the latest update but is occurring due to an update Facebook made to its website that’s potentially related to circumventing ad blockers.

    We’re currently analyzing the situation and will make the necessary changes to resolve this issue.

    Strange, as ABP 3.3 was released two or three months ago, and my problem hasn’t been happening anywhere near that long! I only noticed it in the last week or two in fact, which is why I assumed it started with 3.4.
    Glad to hear that it’s being addressed anyway!
    Cheers, Dave.
