2006 bumper extension removal

I've searched the archives and haven't found anything on how to remove the front bumper extensions. I've removed the push clip under the bumper, but the tabs don't want to pop out of the bumper assembly despite some serious force. Does this require removing the wheel well liner to access the back side? Can the tabs be squeezed from the back side to release them?

Thanks, that is helpful for removing the bumper, which I'll do soon to repaint it. But I'm wanting to know how the bumper extensions, i.e., the pieces that continue the fender flares into the bumper, come off. Can these be removed without taking the bumper off? The tabs don't seem to want to pop out.

 

From the video:

I'm pretty sure those blue clips are what holds it on the bumper cover.

 

Thanks.
