[RESOLVED] XSS filter problems on various sites?

With the last few development builds I've noticed an increase of XSS warnings.
These are reproducible with 5.0.6RC6:

https://www.consoleshop.nl/product/7853 ... -snes.html

Also I've noticed I need to reload a page when I load a page on my local lan, even if I've allowed the page.

See the linked screenshot:

Try manually whitelisting the full address with the port -

Code: Select all

Thanks, that seems to work. still strange it also works without the port number after a reload.

You're welcome.

Regarding the XSS warnings:
When this issue occurs, do you see anything related in the Browser Console? (Ctrl-Shift-J)
(if you don't know what's related, turn off CSS warnings and post everything else you see)

This seems to hit e.g. downloads on github.com quite often. A download of mozregression-gui.exe triggers the XSS protection while Git-2.13.2-64-bit.exe doesn't. Nothing obvious in the console of the browser toolbox.

Does Marking facebook.net as Untrusted make any difference?
