[Support] uBlock Origin

@gwarser, I found the source of the problem I was having last week – it was a conflict with the CanvasBlocker extension, which I’d updated at the same time I updated uB0. See https://github.com/kkapsner/CanvasBlocker/issues/214 for details.

Ah, yes, sorry I did not come up with this. Maybe if you would mention other extension. This Firefox behavior is known for 2 months already (bugzilla 1462989) - was discussed internally with connection to uMatrix, but no official issue on uBO issues tracker exists.

No need to be sorry, of course you couldn’t have known since I didn’t mention it. Thanks for helping us all out here on this forum!

Hi. For starters I’m not at all an advance user. I am trying to save a certain homepage on my browser and after a quick search Mozilla suggested it could be an extension blocking this from happening. My only extension is UBO and I run version 1.16.14. Has this ever happened with UBO? If so, how do I work around it?

^ I should probably mention, of course, that when I try to save a homepage my settings just reset to default after I exit the settings page. I’m not looking for a solution here if it isn’t likely to be anything to do with UBO.

Simple check - disable uBO and try again.

Thanks for you idea!!!

duckduckgo.com uses Javascript to make the entire search result box into a link, even though there are already two normal HTML links inside the box (result title and URL).

Untitled%204

I’d like to deactivate the JS links but can’t quite figure out how to do it.

  • Blocking the script in question (https://duckduckgo.com/d2542.js) kills the entire results page.
  • duckduckgo.com##+js(addEventListener-defuser.js, click) does what I want but also breaks some other functionalities, like switching between web/video/image/news search types.
  • The last comment at https://github.com/gorhill/uBlock/issues/506 is presented as a solution, but it’s not clear to me where I would add that code.

Is there any way to do what I want?

uB0 1.17.4 on FF 64.0; settings: defaults + advanced user, block WebRTC leakage

I can’t find a way either.

Can be narrowed by one more parameter matching in text content of event callback, but ddg uses some library and uBO is seeing only one function.

Defusing mouseover gets rid of this ugly frame at least:

duckduckgo.com##+js(addEventListener-defuser.js, mouseover)

In theory set-constant.js or abort-on-property-read/write.js should help, but nothing I tried works.

Documentation if you want to experiment: https://github.com/gorhill/uBlock/wiki/Static-filter-syntax#scriptlet-injection https://github.com/gorhill/uBlock/wiki/Resources-Library

Yup:

duckduckgo.com##+js(abort-on-property-read.js, fe)

deactivates both the JS links and the frames around them. Thank you for pointing me in the right direction!

fwiw, I recently had a Mozilla problem which I was troubleshooting that lead to starting Mozilla in “Safe Mode” as part of the search for the problem.

As I was opening sites as part of that search, I was dumbfounded by the overwhelming volume of advertisements and other trash which was completely overshadowing the content of every page.

It took me a while to realize that was happening because, among other things, UBlock Origin was one of the things that was not running because of Mozilla’s “safe mode” start.

Bottom line, THANKS!

imho, Everyone should start their browser every few months with UBlock Origin disabled to experience what is being done for us with this incredible tool!

I would like to donate, but it seems that is not possible.

Thanks again,

Beverly Howard

When I attempt to get to certain pages, it blockes bunches of libraries and the page isn’t shown

The page loads fine on my side, using default settings and lists. Given uBO can be customized in many ways (i.e. adding more lists, rules, etc), you need to look into how your uBO configuration differs from default settings/lists. Use uBO’s logger to diagnose such issues.

“abp” subscription link

After using uBlock for almost 2 years now, all over sudden i cant stream any youtube nore bitchute videos anymore. It started yesterday as i noticed a yellow exclamation mark on the menu button of firefox, telling me that uBlock certificate run out (something like that). Since then, no matter what settings i tried, the youtube and bitchute site wont work anymore. I tried removing and reinstall uBlock but with no success.

Are you using Dynamic Filtering? (Advanced Mode?) If yes, you need to adjust your rules for CNAME-uncloaked domains (marked blue).

Youtube is fixed and working. Bitchute is still broken. Changing the rules for CNAME’s didn’t helped. Must be something else.

Hi. I have ublock origin running in expert mode, and I set the red cross on the javascript switch to disallow javascript.
On the website:
https://www.motorola.com/us/smartphones-moto-z4-unlocked/p
below the text more moto z⁴ camera features
I get a working image gallery. As far as I could figure out it’s run by javascript.
Shouldn’t that image gallery be disabled? (Maybe I have some not fitting settings. ):
(I’m not up to date if it is possible to achieve this gallery effect with pure css nowadays; but I doubt it.)
Could anyone help me, please?

This page is blank with JS disabled. Do you have other extensions? For eample Canvas Blocker, HTTPS Everywhere ( encrypt all mode), uMatrix, NoScript?

The only other active add-on was MySessions. (Deactived were DownThemAll, spector.js and stylus.)
Now I tried in the left part of the ublock ui (with all the color red, green, yellow and grey) selecting red in the “local” collum for “vtexassets.com” and “motorolaus.vtexassets.com”, and then I get a blank page,too.
I always thought the red cross in the right bottom border of the UI overrides anything else.
There seems to be only one explanation, isn’t it? I was on that webpage before sometimes, and somehow changed the settings on the “local” collum, though I can’t remember that?
