uBlock Origin and meteoblue.com and other sites too

[Lucio Chiappetti]

uBlock Origin 1.16.6.0 suddenly started a curious behaviour on meteoblue pages.

Try e.g. this page https://www.meteoblue.com/it/tempo/sett ... ia_3166763 with and without uBlock. Before it blocked the ad pictures on the right hand side but showed correclty the weather summary. Now with uBlock the weekly summary plot appears like if a css or some useful resoruces are blocked.

Edit: it looks like other sites are affected, like if some common infrastructure used by more sites has been changed. I cannot say whether this infrastructure is an anti-ad-blocker, or some other provision (perhaps cloudlfare related perhaps not ... it seemed to me a turnstile appeared sporadically somewhere). I had a change of look to an unusable form on sites like https://www.jetpunk.com/user-quizzes/91 ... i-elementi or https://www.trenord.it/

jetpunk is a fun site I visit very rarely, meteoblue is a wheather forecast service it's always in my browser. Trenord is a train operator.

On meteoblue, when I was using ABL instead of uBlock, I got "sporadically" a popup "ask consent to use personal data". By "sporadically" I mean as infrequently as phpBB forums request me to do a complete login (I use Session Manager and load the last saved session when I restar the browser ... a login in this case is requested only after a major machine andf browser restart (e.g. a crash), not if I exit graciously. This popup offers a button to "manage options", which presents categories of ads with consent switched off by default for most cases, and switched on by default for categories listed "legitimate interest". What I did was to turn all off and "confirm". And this was remembered until the "sporadical restart".
Now today also jetpunk shows the same consent popup (that's why I think is a third-party common infrastructure".

Trenord should not have external ads. It is simply a heavilyt javascript infested site. It was very slow to load with ABL, but worked like a charm with uBlock until today.

Now all three sites, with uBlock. show pages with an unformatted layout, like if some CSS or alike was blocked (this sometimes occurred occasionally in a phpBB forum when they were particularly slow, for overload or slow link, like if the content is loaded first and the CSS later).

You are not the only one this is happening to with uBlock Origin (1.16.6.0) enabled for many of the sites I visit everyday. It started happening with me too as of yesterday (Saturday 7-19-25). Some of those sites are mentioned below:

1) YouTube
2) Pale Moon Forums
3) Mint Forums
4) MX Forums
5) gHacks
6) The Standup Zone
7) Weather.gov

The only way to get those sites functioning properly is to "disable" UBO for Pale Moon which is something I do not want to do. I am searching for another solution. One solution is so drastic I will not mention it because it is one of "last resort". BTW, I noticed this after shutting and rebooting thinking it was a "glitch".

On a side note. With Waterfox and Firefox, my backup browsers, using uBlock Origin 1.65.0 and enabled, it is not affecting those same sites.

I suppose you mean mark the site as trusted in uBO.
This is not a problem for ... trusted forums like this one (which anyhow looks unaffected). Or for public sites which have no "ad" (but maybe just the EU cookie notices or some other javascript ... I just disabled UBO on the Regional Health Service site to book a CAT ... not sure if the problem I had with buttons was due to UBO or to the fact I was working without mouse since I had to plug in the smart card reader in my only USB port)

Incidentally ... wikipedia is another site affected by this "new uBO problem"

I am not expert enough to diagnose what was changed in some undetermined common infrastructure ... but I presume an UBO expert could tell which particular filter is affected.

EDIT: as said in viewtopic.php?f=61&t=32566#p264140 disabling the builtin uBlock filters – Badware risks is effective to clear the problem on all sites I tried. However it looks like it is a family of about 10000 individual filters (sic!) and I don't like the idea of running without them when maybe just a handful of them is the culprit. I hope the filter maintainers can do a selective fix

The fix is at the link below in the Goanna Platform (Basilisk).

It's common problem with broken filter "badware risks", does not depend on browser. You can always check UBO's logger.

[moonbat]

In general, any problem with uBO or any other adblocker on other browsers as well, boils down to the filters in use.

[Lucio Chiappetti]

The fix is at the link below in the Goanna Platform (Basilisk).

The "fix" was also quoted in my message just above yours. However as I said I'd feel ill at ease to disable permanently a filter family with thousands of filters when possibly just a handful were causing problems.
Anyhow now it looks "all clear" with filters enabled on the sites I mentioned. I suspect the filters were updated.

For my education, the "last update" time (clock icon) in the uBO dashboard does refer to a periodic automatic update or to a manual action ?
For me it says 12 hours, which could be more or less the time I disabled and later re-enabled the filters.

Keep in mind I am a non-technical user where you have much more computer software knowledge than I have.

With my above statement, concerning the Badware filters, if there is 10000 individual filters and maybe a handful of them is causing a SEVERE problem in Pale Moon, how do you think a non-techncial user like myself is going to find those few by myself and solve the problem?

The answer is basically, I will not be able to on my own. Then for all intents and purposes, Pale Moon would be useless for me to keep using it. Speaking just for myself, any browser where an adblocker does not work........is a "death knell" for that browser.

You state that you do not like the idea of "running around without them" when a handful of filters is causing a problem. But for me, I do not mind running around that way if those handful of filters act up again. In essence, I will "cross that bridge" if and when I come to that bridge if this ever happens again.

I think you are overestimating my competence!!!. I might have knowledge related to my former job (astronomical data analysis), but I am surely not an expert in adblock filtering. And I had no idea of your personal competence, or the one of any other forumer. I just hope that some uBlock developer is listening and able to intervene and/or explain,

My dislike for disabling in full something called "Badware filters" is just due to the intimidating name.
Since now all seems back to normal with the affected sites, I am presuming (or guessing) that there was a handful of filters wrongly included in the badware risk family, and that they were sort-of-promptly (1-2 days) removed and propagated. Or otherwise that several websites were using some common infrastructure which triggered some of the badware filters, and this infrastructure was fixed.

Off-topic:
If your former job was dealing with astronomical data analysis, your knowledge is "w-a-a-y-y-y" beyond my knowledge since my former job, which I retired from, was in the maritime industry where I was "comfortable" (knowledge wise) at sea at the helm of a sea going vessel during a minor or major storm instead of "navigating my way around a desk" at the corporate headquarters on dry land.

But I too was glad to see this problem was fixed because it was really causing HAVOC with "all" of my forum sites I visit everyday using 64 bit linux Pale Moon. This problem also caused damage on my non forum sites as well and there are a lot of those I visit everyday too.

Looks like the recent filter was also causing trouble with newer uBO on some other browsers.

[Night Wing]

So someone made a commit which caused the problem(s)? Either unintentional or intentional? If intentional, evil.

[UCyborg]

The one above didn't strike me as intentional.

There's also an error in Phishing URL Blocklist, first thing on the list is &

Does anyone have GitLab account to report an issue here? I can't sign up, I just get an empty verification page.

[UCyborg]

Filed an issue for Phishing URL blocklist.

[Blacklab]

Filed an issue for Phishing URL blocklist.

Thank you for the explanation. It had seemed most bizarre that the Phishing URL Blocklist was only causing problems with Pale Moon & Basilisk... as I'd noted in another thread last weekend:

Definitely an odd change to the 'Phishing URL Blocklist' recently... if enabled in uBlock Origin that filter list now blocks searches using DuckDuckGo with message "Oops... The server encountered an error and could not complete your request."... exactly the same result in Basilisk.

More curious is that with the same 'Phishing URL Blocklist' enabled in current Firefox 141.0 or LibreWolf 141.0-1 all works normally?

[UCyborg]

I updated our legacy filterlist to mark & as bad filter. Either use Purge all caches in uBo's settings on Filter lists tab then click Update now or just click the clock icon near uBlock filters – Legacy under Built-in and then click Update now.

At least that'll work assuming you're using uBO from https://github.com/UCyborg/uBlock-for-firefox-legacy and not the old one from https://github.com/gorhill/uBlock-for-firefox-legacy.

Done!

Really, it feels pretty magical to check for updates, FINALLY get one, and from 40 minutes ago no less.

@ UCyborg

Thanks for updating UBO to version (1.16.6.1).

I checked as I still thought I had the older version (1.16.6.0) and I do not. Guess it might have updated on it's own.

Again, thanks for keeping an eye on it and updating it. It is much appreciated by me.

And many others.

Technically, it was Pale Moon that updated it.
