[Ext] uBlock Origin

[GHM113]

I have a stupid question. I tried to import 6 filters into uBlock Origin (latest beta) using the box at the bottom of the page in settings - 3rd-party filters (the one under the title "One URL per line. Lines prefixed with ‘!’ will be ignored. Invalid URLs will be silently ignored"):

https://easylist-downloads.adblockplus. ... ilters.txt
https://easylist-downloads.adblockplus.org/easylist.txt
https://easylist-downloads.adblockplus. ... s_full.txt
https://easylist-downloads.adblockplus. ... social.txt
https://easylist-downloads.adblockplus. ... rivacy.txt
https://easylist-downloads.adblockplus. ... sylist.txt

However, after I press Parse only 4 new filters appear under "Custom" title, two filters are missing: https://easylist-downloads.adblockplus. ... social.txt and https://easylist-downloads.adblockplus. ... ilters.txt
Why are two filters missing?

I'd guess it's because they're already in the built-in list of filter subscriptions.

How to force an update of subscriptions in uBlock Origin 1.10.7rc0?

[Virtual_ManPL]

@ barbaz - "Purge all caches" first, and next "Update now"

@ barbaz - "Purge all caches" first,

I only want to force update individual subscriptions, for which the "purge cache" buttons are gone. They seem to be replaced by a clock icon that just says when the last update occurred.

It's not very intuitive, but I figured out how to do it...

• Click on the clock icon - It will turn into an exclamation mark within an orange triangle
• Then click on 'Update now' and only those subscriptions that have the orange triangle will update

@ barbaz & Soothsayer - nice find

That works, thanks Soothsayer!

@gorhill, can you please make this feature obvious again?

I'm finding some sites intermittently problematic, and I'm not sure if that's due to my uBlock Origin filters. So I'd like to have the logger always open in the background. Or running even when not open, so that when I open it it shows all the logged requests.

How to do this?

I tried setting "chrome://ublock0/content/logger-ui.html#" as an additional homepage, but it doesn't log anything in that case.

If I pin a tab with "chrome://ublock0/content/logger-ui.html#", it works in my case with both Nightly/Firefox stable, the log is getting filled with entries at launch time.

What version of uBO is that? With version 1.11.0, if an imported filter list matches one of the stock filters, the matching stock filter one will be automatically selected. See issue 1181.

Thanks. In light of this, I'm doing some troubleshooting, and it appears that the problem is some horrible extension conflict. I've outlined my findings below in some detail. Where should this be reported to?


In my main profile, both "Mozilla Archive Format" and "NoScript" appear to be preventing the uBlock Origin logger working as a homepage. Disabling both of those addons gets it working again.

However, that's not the whole story - disabling "µMatrix", leaving all my other addons enabled, also gets it working.

But, however, installing all four of those addons in a clean profile is not enough to reproduce the issue.

After hours of fiddling about, I finally got it reproduced in a clean profile. As it turns out, uBlock Origin plus any one of the aforementioned other extensions is almost enough. (note: I was disabling the others, not removing them.)

And with that - setting the following homepage prefs, closing all webpages, clearing all browsing history, and restarting/retrying a few times seems to do it.

Code: Select all

user_pref("browser.startup.homepage", "data:text/html,%3C%21%64%6F%63%74%79%70%65%20%68%74%6D%6C%3E%0A%3C%6D%65%74%61%20%63%68%61%72%73%65%74%3D%22%75%74%66%2D%38%22%20%2F%3E%0A%3C%73%74%79%6C%65%20%74%79%70%65%3D%22%74%65%78%74%2F%63%73%73%22%3E%0A%62%6F%64%79%20%7B%0A%20%20%62%61%63%6B%67%72%6F%75%6E%64%2D%69%6D%61%67%65%3A%20%2D%6D%6F%7A%2D%6C%69%6E%65%61%72%2D%67%72%61%64%69%65%6E%74%28%2D%36%30%64%65%67%2C%20%67%72%61%79%2C%20%61%7A%75%72%65%29%3B%0A%20%20%62%61%63%6B%67%72%6F%75%6E%64%2D%72%65%70%65%61%74%3A%20%6E%6F%2D%72%65%70%65%61%74%3B%0A%20%20%62%61%63%6B%67%72%6F%75%6E%64%2D%61%74%74%61%63%68%6D%65%6E%74%3A%66%69%78%65%64%3B%0A%7D%0A%3C%2F%73%74%79%6C%65%3E%0A%3C%64%69%76%20%73%74%79%6C%65%3D%22%6D%61%72%67%69%6E%2D%74%6F%70%3A%31%30%30%70%78%3B%6D%61%72%67%69%6E%2D%6C%65%66%74%3A%35%30%70%78%3B%22%3E%0A%3C%70%72%6F%67%72%65%73%73%20%69%64%3D%22%6C%22%20%6D%61%78%3D%22%31%30%30%22%3E%3C%2F%70%72%6F%67%72%65%73%73%3E%0A%3C%2F%64%69%76%3E%0A%3C%73%63%72%69%70%74%20%74%79%70%65%3D%22%74%65%78%74%2F%6A%61%76%61%73%63%72%69%70%74%3B%76%65%72%73%69%6F%6E%3D%31%2E%38%22%3E%0A%76%61%72%20%6C%20%3D%20%64%6F%63%75%6D%65%6E%74%2E%67%65%74%45%6C%65%6D%65%6E%74%42%79%49%64%28%27%6C%27%29%3B%0A%77%69%6E%64%6F%77%2E%61%64%64%45%76%65%6E%74%4C%69%73%74%65%6E%65%72%28%27%6C%6F%61%64%27%2C%66%75%6E%63%74%69%6F%6E%28%29%20%7B%0A%20%77%69%6E%64%6F%77%2E%73%65%74%54%69%6D%65%6F%75%74%28%66%75%6E%63%74%69%6F%6E%28%29%7B%6C%2E%76%61%6C%75%65%3D%22%31%30%30%22%7D%2C%31%30%30%30%29%7D%2C%66%61%6C%73%65%29%3B%0A%3C%2F%73%63%72%69%70%74%3E%0A%3C%62%72%2F%3E%0A");
user_pref("browser.startup.homepage.1", "chrome://ublock0/content/logger-ui.html#");
user_pref("browser.startup.homepage.count", 2);

Browser is SeaMonkey 2.46, as indicated below.


EDIT I just tried on another machine, with my same profile, and there it seems some other addon(s) are also conflicting with uBlock Origin in this same way.
EDIT2 There are two additional culprits - both are my own addons. These same versions of these same addons did not produce the issue in the first machine. Same version of SeaMonkey on both machines. What to make of that?

What version of uBO is that? With version 1.11.0, if an imported filter list matches one of the stock filters, the matching stock filter one will be automatically selected. See issue 1181.

To say honestly, I don't remember. I've just tested the latest beta and it looks like this feature is working as intended.

Also, a little question about ABP and uBO performance parity.
https://bugzilla.mozilla.org/show_bug.cgi?id=1280368

...we should consider implementing an asynchronous API for content blocking which could replace nsIContentPolicy. Our content process code needs to query the parent for content policy decisions because that's where the state is. Currently it has to happen synchronously because nsIContentPolicy requires a synchronous decision - so rather than delaying a single network request slightly we block the entire content process every time. This is currently causing performance issues in Adblock Plus

Does anyone know if this asynchronous API for content blocking is supported by WebExtensions? I am trying to figure out when ABP will finally catch up with uBO in terms of performance.

Bug or feature? I tried to google but didn't find anything.

From the releases page -

New static network filter option: badfilter. Using this option will prevent the filter to be loaded in memory. See uBlockOrigin/uAssets#192 for rationale for having such a filter option.

I had been, informally, using the "fake" filter option $invalidated to cause uBlock Origin to discard an otherwise-valid filter. What is the difference between continuing to do that and using the new $badfilter option?
