Many websites that require login use scripts to process the login. For people who use Noscript, what sites are on your whitelist?
Using NoScript (or another script blocker) doesn't necessarily involve blocking (or allowing) "each and every script on all sites".
I have a number of
domains on my NoScript whitelist ("anandtech.com", for example), but I don't have
any "website" whitelisted in the sense of allowing "all scripts" called from any/all of a particular "site's" pages. And I also have
quite a few domains marked as "untrusted", so even when I "temporarily allow this page", scripts from those "blacklisted" domains stay blocked.
ETA: I also use AdBlocker. I've also tried μblock, which seems to combine both functions, but probably just because I'm not used to it, I've found it somewhat confusing. And so far anyway, the combination of NS and ABer serves my purposes. I'm not trying to pull a Gene Hackman (in
Enemy of the State, that is). I just like to block at least the more blatant general-purpose trackers and ad-servers, and
especially as much as possible of the resource-hogging nonsense that so many sites seem clogged up with these days, to no end that benefits me. Most sites "work" just fine with only some of their scripts allowed, and it didn't take very long to figure out which those critical scripts were, by trial and error. A very few sites act wonky without allowing almost all the scripts they try to call, but those are so rare and so non-essential, I just live with their wonkiness. (Slickdeals currently being the biggest offender, but that site has become so generally pointless I really don't care if I can't access all of its functionality or if some views/pages refuse to load properly.)
