Not blocking Google ads on first launch

[mattb5906]

For some reason the plugin is not blocking ads on Google each time I initially open Firefox. The "Allow some non-intrusive advertising" check box is unticked.

If I refresh the page the ads disappear as expected. I've had this happen on multiple machines all running Windows 10.

See examples below:

Any ideas if this is Firefox related or the plug-in itself (some sort of delayed start?)?

Thanks

years ago ABP was blocking the ads on the FF start, but this provoked a delay on the whole browser (which was waiting ABP starting), users complained and the devs ... changed the ABP behaviour.

Thanks the info mapx. It's only started happening recently for me (months not years).

If I keep typing in new queries the plugin still doesn't filter the ads even after >2minutes. It only starts filtering if I click through to a link or if the page is refreshed. If I open the links in a new tab/window, it still keeps showing the ads in the original.

Maybe it's how Google uses AJAX to show the new results without refreshing the page.
