Description

After navigating on some pages of easyjet.com website, the browser suddenly stop to successfully contact easyjet.com.

I have found a closed issue : #11715 and a reddit thread about that problem : https://www.reddit.com/r/uBlockOrigin/comments/rovnm8/is_ublock_origin_messes_booking_pages_on_easyjets/

I can confirm disabling uBlockOrigin and deleting cookies from Firefox website menu solves the problem : I can navigate fully on the website.

I also experienced it. Like if your IP was "banned" on easyjet side. But if you can try with another IP (or wait some time) and with no ublock addon, it will work, if it is the same behavior as me.

Akamai ban?

https://github.com/easylist/easylist/issues/14805

Indeed, this is the EasyPrivacy filter (see linked issue) causing an Akamai block (confirmed by deleting the ak_bmsc fingerprint cookie after being blocked).

@mapx- Not a site issue. Should be reopened.

Does the filter @krystian3w suggested work?

easyjet.com##+js(cookie-remover, ak_bmsc)

[krystian3w]

For my on my side doesn't work, but I don't have a text message similar to ing.nl - the loading of the page access request has stopped similar to slow bandwidth.

Manually delete itself for few time disable fake slow bandwidth.

[ius]

@krystian3w to clarify, the implementation of Akamai Bot Manager on easyjet.com indeed is slightly different compared to ING. It doesn't return a 403, but simply drops the connection if you provide a ak_bmsc cookie it deems unacceptable.

Another major website. I'd like to reiterate many others won't be reported as far as coming up with a solution. In this issue there's confusion about disabling uBlock not helping and it being a site issue, and that's after someone went through the effort of reporting it in the first place..

Deleting the cookie works (at least temporarily), but that seems like a website-specific fragile solution.

[krystian3w]

But we have to continue to do it manually until someone experienced catches on to what the scriptlet is blocking in both cases.

It is unlikely that Akamai script approvals will be added (they do not fool with noop.js/noop.txt), and the cleaned-up surrogate redirect resource may be too difficult to write.

[stephenhawk8054]

Site-specific unbreaking is not uncommon (similar to many sites in unbreak list), especially if it's related to tracking connections. The important thing is whether there's any solution filter to it except allowing the connections or not.
