Receiving XSS warnings for EVERY website - Firefox

Post by option1 »

As the title says, I'm receiving XSS warnings for every website I go to in Firefox. This only started in the past day or so and may be related to the most recent MS Windows 11 update installed about the same time.

The origin of the supposed cross-scripting attack is different for every website, and can include from parts of the same website, e.g. a warning/attempt to block media.reddit.com when on reddit.

Incredibly moronically annoying. Please fix or explain.

What version of NoScript are you using?

Could you please share the full text of a few of these XSS warnings from different websites?

What other extensions are you using?
Does disabling all extensions other than NoScript stop this behavior? (Tools > Add-ons and Themes)
*Always* check the changelogs BEFORE updating that important software!
