Does this forum use META redirects?

I have removed all pre-installed whitelist rules (except about: ones).
I have checked an option to forbid META redirects.
However, whenever I submit a post to this forum - it opens a temporary page which then redirects me back to the topic I posted to.
How is that possible? Scripts are forbidden globally, this site is not whitelisted, META redirects are forbidden too.

Code: Select all

<meta http-equiv="refresh" content="3;url=http://forums.informaction.com/viewtopic.php?f=7&t=14140&p=52556#p52556" />
Though that is not within <NOSCRIPT> elements, so NoScript does not block it.

Mozilla has a general accessibility.blockautorefresh (about:config) which should block it.

So it is possible to create a site consisting of two pages with each of them redirecting to another one [in a loop] and NoScript won't be able to block that?
Why does NoScript handle META redirects then at all? I think NoScript should either handle ALL the redirects, or NONE.

If that is the normal behavior of those sites, regardless of script execution, then yes. If you want to control redirects, try RequestPolicy.

I believe this is primarily to stop sites from saying "Since you've disabled JavaScript (and hence our advertising), we'll redirect you away from our content."

So NoScript loses even to such an outdated add-on as RequestPolicy.
That's lame, mmkay?

You should double-check your sources on the whole "RequestPolicy is out of date" joke. You've been rickrolle'd.

As for the meta redirects, you can use RefreshBlocker add-on. It deals with that particular kind of redirects.

Possible? Yes. It is also possible for websites to serve blank pages for instance. What do you recommend? Block all pages from loading so we never get the hypothetical blank page?

Thrawn explained that very nicely.

I recommend the user to have control over all redirections, so the user decides whether to block or to allow them.

Firefox Options - Advanced - General - Warn me when websites try to redirect or reload the page.

Thanks, Thrawn.
But there is no whitelist for sites to allow redirections.

RefreshBlocker has already been mentioned. I'll once again mention RequestPolicy, too.
