No page can load while uBlock is active

[j36e]

Prerequisites

• I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
• This is NOT a YouTube, Facebook or Twitch report. These sites MUST be reported by clicking their respective links.
• This is not a support issue or a question. For support, questions, or help, visit /r/uBlockOrigin.
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.
• I checked the documentation to understand that the issue I am reporting is not normal behavior.

I tried to reproduce the issue when...

• uBO is the only extension.
• uBO uses default lists and settings.
• using a new, unmodified browser profile.

Description

output.mp4

Pages won't load with UBO enabled but everything works fine when it's off. Everything was fine a couple of hours ago and yes I did reboot my computer.
Sorry for the bad video quality my laptop is slow

A specific URL where the issue occurs.

https://github.com/uBlockOrigin/uBlock-issues/issues/new?assignees=&labels=&projects=&template=bug_report.yml

Steps to Reproduce

1. [Enable UBO]
2. [Try to load a page]

Expected behavior

The page to load

Actual behavior

It did not :(

uBO version

1.57.0

Browser name and version

Chromium (chromium-123.0.6312.86_1)

Operating System and version

Void linux

The first tab title seemed to load but it was probably cached since I tried the same query minutes before

When you click uBO's "background.html" link in chrome://extensions/, this opens the browser tools for uBO. Can you see something reported in the console pane?

[j36e]

Lmao the addon wouldnt do anything when I clicked on it so I reinstalled and it's all working now sorry for the stupid issue report

[gorhill]

We had other reports of such behavior, so I don't consider this invalid. Problem is that so far I have been unable to investigate further since the issue disappear upon reinstall.

@j36e Do you think that uBO had just updated to 1.57.0 before the issue occurred?

I faced the same issue too. But in my case, after updating to 1.57.0, i lost all saved filters too and uBO was completely reset to default. allReadyAfter after this incident was over 80k ms. The dashboard was completely blank after this, restarting my browser did fix it, but had to continue from a old backup.
Browser used: Edge
Possible in #3219, OP did face something similar (chromium used)

@voidlyvidevoid Can you do the steps described in this: #3217 (comment)

j36e : No page can load while uBlock is active
j36e : Pages won't load with UBO enabled

Also possible you encountered the same like here:

• Kiwi browser #3198 : (spain): "y no me carga ninguna web se queda cargando" :
  (enlgish): "and it doesn't load any web site it just keeps loading"

---

voidlyvidevoid : allReadyAfter after this incident was over 80k ms

In this one 85k ms too:

• drakescans.com: detection uAssets#23344

also you can read (if you didn't see them before):

• Longer time-to-readiness with Chromium 110 uAssets#16939
• Investigate unduly high time-to-readiness as reported in uAssets issue tracker #1865

Tho this happend a few weeks ago when the update was pushed. Never had anything over 15k ms except when this occured. I get 12-15k ms consistently in FF and Edge and I take the blame for that as I have nearly 500k+ network filters (mostly badware, malware and anti-paywalls)
Also, something maybe unrelated, Edge takes a good 30s after restart to load anything.(this is with and without suspendUntilListsAreLoaded: true)

@voidlyvidevoid Can you click on uBO icon > 💬 Report button > scroll to the bottom > click on Troubleshooting Information and copy paste it here?

I usually don't find them these high, but 12-15k ms and some 3k is mostly consistent. This is immediately after a restart, with 12 tabs open from previous session. (Using hard mode,with block large media)
Other extensions: Webtime tracker and Dark reader

@voidlyvidevoid This gitlab user is removed by Gitlab already so its filter list cannot be updated: https://gitlab.com/magnolia1234/bypass-paywalls-clean-filters/-/raw/main/bpc-paywall-filter.txt

You are using a heavily modified configuration so we cannot pinpoint what causes the issue. Backup and reset to default settings and test again. Then restore your configuration one-by-one and see which one is causing issue.

Anyways, since you can access uBO's dashboard, I don't think your issue is the same as this issue. It's more similar to this: #1865 so please continue in that thread instead. But do what I said above first.
