RSS feed not working since this morning

Post by mkz » Wed Mar 14, 2018 2:46 pm

An RSS feed that I use (on an internal server, on port 8080) has stopped working since this morning. Other pages on this server work fine, but the RSS feed just comes up blank (after appearing very briefly). It works fine without NoScript installed. I have reproduced the problem on another machine.

What version of NoScript?
Did FF update this morning too (from FF 58 to FF 59)?

Anything related noted in Error Console?

NoScript 10.1.7, which Fx says was "last updated 14 March 2018", so I assume it's that. I updated Fx yesterday. Nothing related in the error console.

I've reverted to 10.1.6.5 and it's working again. There's definitely something wrong with 10.1.7.

I could reproduce with NoScript's own feed. Investigating, thanks.

I'm afraid I'm still seeing the same problem in 10.1.7.2.

Please double check. I could actually reproduce your problem on https://noscript.net/feed on 10.1.7, but not on 10.1.6.5 neither in 10.1.7.2 (I had actually found and removed a culprit).
If you can confirm, please try to send me at least the source code of this RSS feed and your configuration export for me to test.
Thanks!

I have double checked: it's definitely failing. http://rss.cnn.com/rss/edition.rss fails the same way for me, even though "cnn.com" is in my trusted sites list.

Looks like the rss feed fails if scripts are enabled and works when they are disabled.

Sorry, I cannot reproduce on http://rss.cnn.com/rss/edition.rss either: it works for me no matter if cnn.com is DEFAULT or TRUSTED.
Could you try on a clean profile with just NoScript installed?
If that works, could you please send me your NoScript Options>Export file from your regular profile and check whether NoScript Options>Reset makes things better?
Thank you!

I decided to give a hand and debug this. My test with a clean profile showed this issue occurs when a site with RSS feed is trusted without WebGL permission. Yes, you red that right, what peculiar connection between RSS feeds and WebGL is I don't know, but that's how things stand.

Thank you so much!
Actually there's a connection, which is the way NoScript delivers additional content scripts when WebGL interception is required. It seems the options available in WebExtensions for this are rather buggy yet: I'm investigating what happens actually under the hood and providing a work-around. Thank you for your finding!

This seems fixed at my end. Waiting for @mkz and/or @skriptimaahinen .
