UBlock Origin Lite - Nice adblocker for modern challenges

EUREKA !!!
Said the great Archimedes out loud.

Guys I got it.
Unfortunately, it is necessary to distinguish each and every TLD rule + exceptions.
Other important point the priority,you need to give the same priority to all the rules.

Code:

priority: 4
action:
  type: block
condition:
  urlFilter: *
  domainType: thirdParty
---
priority: 4
action:
  type: allow
condition:
  urlFilter: *://*.eu/*
  domainType: thirdParty
---
priority: 4
action:
  type: allow
condition:
  urlFilter: *://*.info/*
  domainType: thirdParty
---
priority: 4
action:
  type: allow
condition:
  urlFilter: *://*.io/*
  domainType: thirdParty
---
priority: 4
action:
  type: allow
condition:
  urlFilter: *://*.ms/*
  domainType: thirdParty
---
priority: 4
action:
  type: allow
condition:
  urlFilter: *://*.net/*
  domainType: thirdParty
---
priority: 4
action:
  type: allow
condition:
  urlFilter: *://*.it/*
  domainType: thirdParty
---
priority: 4
action:
  type: allow
condition:
  urlFilter: *://*.org/*
  domainType: thirdParty
---
priority: 4
action:
  type: allow
condition:
  urlFilter: *://*.edu/*
  domainType: thirdParty
---
priority: 4
action:
  type: allow
condition:
  urlFilter: *://*.com/*
  domainType: thirdParty
---
priority: 4
action:
  type: allow
condition:
  urlFilter: *://*.co/*
  domainType: thirdParty
---

The 'last rule is the exception for the image in MSFN.
Although it is not very easy to insert exceptions,because often the specific url seems not to work.

If you want to do another test you can momentarily change the rule com in som.
And then go to ChatGPT -test.
In the absence of third party the website has a broken layout.

However, it is quite a feat to be able to use uBlock origin Lite in Hard Mode + TLD.

P.S.

Now for those using uBlock Origin Lite will need to check if there are any other exceptions to add to any broken websites.

How do you go about identifying what is not working?

It will be necessary to use another extension that has Log.
Or more simply disable filtering in some websites that are not working.

P.S.1

I have included the necessary exceptions (7),the same ones used in AG.

 

Thanks, I will end the short period I experimented with it. So goodbye uBO Lite.

I wrote 3 DNR rules to block malicious files from Github.com ( only exe,7z,zip):

Code:

action:
  type: block
condition:
  urlFilter: github.com/*/*.exe
  resourceTypes:
    - main_frame
    - sub_frame
    - script
    - image
    - object
    - xmlhttprequest
---
action:
  type: block
condition:
  urlFilter: github.com/*/*.zip
  resourceTypes:
    - main_frame
    - sub_frame
    - script
    - image
    - object
    - xmlhttprequest
---
action:
  type: block
condition:
  urlFilter: github.com/*/*.7z
  resourceTypes:
    - main_frame
    - sub_frame
    - script
    - image
    - object
    - xmlhttprequest
---

For any tests (be careful to choose exe,7z,zip links):

https://urlhaus.abuse.ch/browse.php?search=github

P.S.

Obviously the rules also block legitimate Github exe,7z,zip downloads,to avoid this inconvenience you need to set the extension slider to no filtering.

I was sceptical when I first switched Chrome and Edge from uBlock Origin to uBlock Origin Lite. But it works very well. It works much better than I expected.

By the way. It appears that uBlock Origin Lite is no longer available for Firefox.

 

Mozilla Add-ons messed up the review of uBlock Origin Lite, see:
https://github.com/uBlockOrigin/uBOL-home/issues/197#issuecomment-2329365796
That is why the developer, Raymond Hill, gorhill, decided to stop offering uBOL for Firefox:
https://github.com/uBlockOrigin/uBOL-home/issues/197#issuecomment-2377395301

 

"Malicious URL Blocklist" has 3391 network rules.
Few rules to be efficient.
So it is not only a problem of late update of filter list.
Better search for anti-malwares protection elsewhere.

 

Unfortunately, the new rules must be entered later separately:

Code:

action:
  type: block
condition:
  urlFilter: raw.githubusercontent.com/*/*.zip
  resourceTypes:
    - main_frame
    - sub_frame
    - script
    - image
    - object
    - xmlhttprequest
---
action:
  type: block
condition:
  urlFilter: raw.githubusercontent.com/*/*.exe
  resourceTypes:
    - main_frame
    - sub_frame
    - script
    - image
    - object
    - xmlhttprequest
---
action:
  type: block
condition:
  urlFilter: raw.githubusercontent.com/*/*.7z
  resourceTypes:
    - main_frame
    - sub_frame
    - script
    - image
    - object
    - xmlhttprequest
---

With the current sampes, the blocking performance is 100%.

 

Thanks for the info.

Interesting possibility in the next version of uBo Lite for many users.
Note that you specify network filter (not cosmetic).

I have 2025.709.1622 in Chrome.

 

In uBlock Origin Lite it is now possible to create a custom filter that is specific to each web page.
That custom filter can then be removed from the same web page where it was created.

 

https://www.ghacks.net/2025/07/13/i...me-use-ublock-origin-lite-or-another-browser/

I have included some comments.
There's no use wrapping your head before you break it.

 

@Sampei Nihira

quoting from the link you provided above:

Do you actually find this to be the case?

 

Not really,my implementation of Hard Mode + TLD via DNR rules proves it.
Certainly uBlock Origin still has some advantages over uBlock Origin Lite for example the Log,which can be remedied via browser development tools.

Or this:

https://github.com/uBlockOrigin/uBOL-home/discussions/385

I hope Gorhill can implement this feature I requested,and uBlock Origin Lite could become in daily use friendlier than what is perceived currently.

 

Thank you I'm still using Floorp browser with uBlock Origin, so no concerns yet about using a Chrome-based browser with uBO lite.

 

But this is beside the point of @wat0114's quote, which refers to very average µBO users, who "as a rule of thumb" use no special configuration except default.

 

Very average users will not (even now) use uBlock Origin Lite without noticing any difference with uBlock Origin.
So I equally disagree with the quote from the article.
The 'very average user even currently is not able to properly make a temporary exception in the block page of uBlock Origin Lite,which is super simple in uBlock Origin.
I would bet that such very average users will instead make a permanent exception and not be able to change this unintended permanent choice of theirs.
This is one of the reasons why I requested the feature change.

 

Average users will hardly notice this because not many of them will encounter blocks, especially large numbers of blocks. And this is not one of the main features in any case.

 

Average users couldn't care less; they just use uBO's default settings.
