Description

Can the security fix for uBlockOrigin/uBlock-issues#1649 be applied to this repo, as well?

I confirmed that the DoS issue also affects the legacy extension and Pale Moon.

Thank you.

Thank you. As soon as I come back from vacation, I will release the necessary update. Fortunately, the problem itself does not look so critical to require immediate intervention.
