site bancsabadell.com hangs with NoScript

For some time I've been unable to access one of my banks' website, https://www.bancsabadell.com, in Firefox. It works fine in Chrome.
I recently got tired of occasionally hanging myself :) and started properly debugging.
Here's what I've found:

This is reproducible on Firefox, any recent version up to the current 44.0.2, in my case on Windows 7 64-bit (with all service packs and patches applied).
With NoScript any recent version up to the current dev 2.9.0.4.

Site: https://www.bancsabadell.com

To reproduce the problem:
Start with a blank Firefox profile.
Install NoScript.
Visit the site [url]https://www.bancsabadell.com[/url]
Click the NoScript toolbar icon and select the Allow the bancsabadell.com site.
Watch Firefox hang :-(

No debug log is available as Firefox hangs hard and must be killed to recover.

Issue certainly sounds familiar.
And almost always, banks are involved.
Some odd Full Domain (subset of bancsabadell.com) that buggers things up.
Don't know that I've actually seen a reason why this seems to continually affect NoScript users?

Once I allowed datalog.bancsabadell.com it says, "waiting for datalog.bancsabadell.com...", at which point it is hung.


NoScript | Options | Appearance ->
(check) Full Domains

Load www.bancsabadell.com
Temporarily Allow www.bancsabadell.com

At that point datalog.bancsabadell.com should then become visible

Go to the Untrusted menu, & mark datalog.bancsabadell.com as Untrusted

Options | Appearance
(uncheck) Full Domains (if you no longer need it)


See if that then works for you.
(Other threads talk about messing with ABE, if I recall.)

Hi @therube,
Thank you! I don't understand why ALLOWING a particular (host with).bancsabadell.com would cause the site to hang, but in fact that was it exactly - with Full Domains displayed, allowing me to Allow the top level domain while leaving specifically datalog.bancsabadell.com Untrusted, the site works in Firefox with NoScript!

It does seem to be something that the NoScript team should look in to for a future more general fix.

cheers,
Jay

Downgrading from NoScript 2.9.0.4 to NoScript 2.7 allowed me to login to my online bank without any problems and without changing any of my previous NoScript settings, just as I was able to do before. I am currently using Firefox 44.0.2.

Previous versions of NoScript can be found here: https://addons.mozilla.org/en-US/firefox/addon/noscript/versions/

Downgrading NoScript may not be the best solution but I do not know of any other solution.

*Always* check the changelogs (at AMO too - changelogs there are at billdfixer's link) to see what fixes you'll be missing out on, BEFORE downgrading NoScript that many versions!
In this case, I think that old NoScript will not work at all with recent Gecko, due to Gecko removing features those old NoScript versions depended on.

@billdfixer: Is NoScript 2.7 the latest working rc build?

The latest rc is 2.9.0.4. With 2.9.0.4, I had to completely disable NoScript in order to successfully login to my online bank. I downgraded Firefox from 44.0.2 to 43.0.x then to 41.0.2 but neither downgrade allowed me to login. The only solution that I found for ANY recent version of Firefox was to downgrade NoScript to 2.7 (note: there is no 2.8). I do not condone downgrading but I could not find any other solution after spending about 8 hours testing different options. If there is a more elegant solution, it is beyond my knowledge.

Based on another post, I upgraded NoScript from 2.7 to 2.9.0.2 and can now login using Firefox 44.0.2. I tried using 2.9.0.3 but the login problem happened again. Obviously, something changed after 2.9.0.2 that causes this login problem on my banking website.

@billdfixer: Until the OP confirms that this issue is the same as what you experience, can you please keep discussion of your issue in viewtopic.php?f=7&t=21630 only? It's really hard to keep track of a single discussion in multiple places.
Thanks.

I'm happy to try 2.9.0.2 to see if the problem with the Banc Sabadell site does not exist in that version.
How do I install a specific NoScript version, e.g. 2.9.0.2? (Sorry to have to ask).
thanks,

Going to say from here, https://addons.mozilla.org/en-US/seamonkey/addon/noscript/versions/ (only because they should be signed, & not sure of otherwise?).

See my earlier post in this thread from Fri Feb 19, 2016 6:34 pm with the link to previous versions of NoScript. Scroll down that page to find the desired version then hover your mouse pointer over it then click on the "Install" button.

My post at the quoted link was to report my problem issue, not knowing where else to report it. My posts in this thread were intended to confirm the issue and help someone else resolve their issue until the underlying problem could be determined and fixed. I can certainly understand the confusion, now, and will post no more. Thank you for pointing this out.

Usually because the site is running a misbehaving script. For example, it might be trying to load something from a domain that is still blocked, and retrying endlessly when it fails...

I tested with 2.9.0.2 - still hangs if datalog.bancsabadell.com is enabled.
So, whatever bandsabadell.com is doing wrong, it triggers something different (or isn't a NoScript problem at all, but rather a badly written script on the bank's website) which is causing it.
thanks to all. I'll pass this along to the bank. (And I won't hold my breath!)
