Pale Moon not saving changes on startpage.com

[SGvagon]

Hello,

I have a little issue on startpage.com , where if I try change settings for Use POST vs GET in Privacy and Safety, id did not save this after click on Save button here https://www.startpage.com/do/settings .

In IE 11, Firefox or Chrome this settings change works.

I am using the latest Pale Moon 28.10.0 64bit.

Thank you in advance for any help, where is the problem.

OT : It's a great alternative for Google search, but these settings for saving history to the browser is important for me.

Ok i fixed it deleting cookies and browser history for this page. Then these settings saved too. Did something go wrong in the first time site load?

No it happened again. All settings has restored to default . But after deleting cookies and history it working again.

Do you use a cookie-controlling extension? Have you tried in safe mode or with a temporary new profile?

vannilla : I don't use any cookie extension. Now I am trying clear profile and still working. As I said, it looks like totally random. Now it still working on my main profile too. Can for example AdBlock breaks these cookies? I have EasyList filters.

You can also save the settings as an encoded URL, without the need for cookies.
