While this add-on is only temporary (if you refresh the page, it goes back to it's previous state) it is VERY helpful. I use it to block annoying sidebars on forums. Thank you!

Perfect for hiding the tiktok chat to watch content fullscreen on a vertical display

and ofc other things

Works like a charm! Thank you, author!

It would be a nice touch though if the link to plugin's homepage[^1] as displayed at plugin's Mozilla page worked. It's broken currently at March 23 2022.

This is great, it is like the element zapper in uBlock Origin, but much easier to access, and with a nicely working undo!

Unfairly, there are a few bad reviews from people who want something different, an automatic or permanent element blocker, rather than a one time element picker. There are other good extensions for that, such as uBlock Origin.

Génial. Marvelous ! Juste ce qu'il faut pour gagner de la place dans une page web. Pour remettre à zéro sans tout annuler un par un il faut actualiser la page ...

It works, but the functionality is not enough. Need to add hiding rules or, at least, the ability to save settings for sites

Exactly what I've looked for! Thanks David!
On my FF 61.0.1 the crtl+shift highlighting overlays its color, i.e. the element colorization remains after mouseout. After ctrl+shift+dblclick the underlying element is highlighted and remains like this.

Control+shift+double-click will pop-up menu, can you customize the key combination?
