MEGA sets a CSP so scriptlets will not work on Firefox and json-prune doesn't stop the ads from getting loaded even we disable CSP on Firefox.

Setting localStorage item pra to {"1":99999999} works.

[uBlock-user]

For Chromium browsers, where site CSP is not an issue, this scriptlet works --

(() => {
		'use strict';
		const item = 'pra';
		const setItem = ev => {
		 			   if (ev) { window.removeEventListener(ev.type, setItem, true); }
					   try {
							if (localStorage.getItem('pra') !== null) { return; }
							localStorage.setItem('pra', '{"1":99999999}');
					   } catch { }
		};
		if (document.readyState === 'loading') {
		    	    window.addEventListener('DOMContentLoaded', setItem, true); 
	   	} else {
		    	    setItem();
	   	}
})();

Will work for Firefox too but will need a bad workaround by disabling CSP functionality via about:config

not fixable with the current weapons

[ghajini]

Why labelled "won'tfix" if there are chances gorhill will fix in near future?

May be good label= Currently No Solution

Probably to add a localstorage scriptlet we would need a few more use cases on other sites.

[uBlock-user]

Why labelled "won'tfix" if there are chances gorhill will fix in near future?

Because it's not fixable with current scriptlets as mapx already said. It will be removed when a fix is added, untill then, label is for clarification. All cases which are fixed never get a label.

I am not subscribed to receive notifications from here -- the reddit thread led me here.

Whenever there are cases that are unsolvable with current arsenal, please mentions me. I have to be aware of all these case for me to understand what is missing in uBO and what is worth to work on. It's also useful to know whether other blockers can deal with these.

@ghajini's suggestion make sense, having a label can't fix or something like this would help list all the currently unsolvable cases to make development decisions.

The code is open source FYI:

a filter of this style would work?: Content-Security-Policy

||mega.nz^$csp=script-src etc.. 🤔

[liamengland1]

why closed?

[gwarser]

@llacb47 They stopped playing ads? I think someone mentioned this on Reddit.
