breakage

Description

Removing ads from the page causes elements to become horizontally squashed, making them awkwardly small, if not completely unreadable. Refreshing the page shows the elements start out at their correct width, then shrink after a split second, as if something is adjusting the page to the elements squishier. Effect applies to all "flashcards" pages on the website. Website sizes elements normally when Ublock is off.

Other extensions used

none

@Agshin2004 You are using a heavily-modified configuration. Test in a new browser profile with only uBO and its default settings (update the filter lists there)

[Agshin2004]

seems to be working but as soon as I import my filters back ui crashes again, is there a way to fix that?

[stephenhawk8054]

Did you click the link above to update?

[Agshin2004]

Yes I did. Btw I tried on google chrome with only 1 filter and it still crashes

But I still think that I’m doing smth wrong

[stephenhawk8054]

What do you mean by it still crashes?

[Agshin2004]

The cards are being squished (look at the photo that was added by shrimp-guy above)

[stephenhawk8054]

I tried on google chrome with only 1 filter

I don't understand what you were doing here. You mean you disabled all the filter lists and added only 1 filter as a custom filter?

Can you go to uBlock filters – Ads list and screenshot the header to here?

[Agshin2004]

yes, sure

[stephenhawk8054]

@Agshin2004 No, I mean screenshot the header of the uBlock filters - Ads list

[Agshin2004]

[stephenhawk8054]

@Agshin2004 That does not look like uBlock filters - Ads list. It looks like your My filters list. Can you screenshot the whole screen?

[Agshin2004]

My bad I’m sorry, I’m just looking at it it’s huge (37737 lines), should I delete it all?

[stephenhawk8054]

@Agshin2004 No, don't delete anything. I also didn't tell you to disable any default lists.

I just told you to SCREENSHOT the uBlock filters - Ads list

Go to Filter lists tab -> Click on the eye icon right next to uBlock filters – Ads word -> It will open a new tab with that list -> Screenshot it.

[shrimp-guy]

Hey I just wanted to say that @stephenhawk8054 was right about the issue, it was "quizlet.com##+js(remove-class, has-adz, div.has-adz, stay)"

I fixed the issue with the following steps:

1. Open UBlock Origin on the Quizlet flashcards page, click "Open the logger"
2. Press the "Reload Tab Content" button
3. Go into the "filter logger content" menu and search for scriptlets
4. Click on "quizlet.com##+js(remove-class, has-adz, div.has-adz, stay)"
5. Click on the #@# button in the menu, which should disable it

Attached below is a demonstration of navigating to a different scriptlet (I think there was 4 before, before the problematic one was removed). Refresh the page and you should see the flashcards in their normal resolution.

[stephenhawk8054]

@shrimp-guy You don't need to manually add that. Updating the filter lists didn't work?

[shrimp-guy]

I was already poking around in the logger and found those javascript files before posting my complaint, so when you mentioned the specific scriptlet file causing the issue I just turned it off rather than resetting the filter lists. I guess the new filter list could be the reason why it doesn't pop up in the logger anymore.

I do agree that just updating the filter list is the most logical course of action. If that doesn't work however, the steps I perform above DID fix the problem for me.

[Agshin2004]

did as shrimp-guy instructed, didn't work for me.

here the list:

[stephenhawk8054]

@Agshin2004 So looks like when you import your configuration, your filter lists do not have differential update. Can you share your backup file to here?

[Agshin2004]

here you go: my-ublock-backup_2024-01-25_16.18.15.txt

[stephenhawk8054]

@Agshin2004 Isn't it your new configuration? I mean the one you mentioned here: https://github.com/uBlockOrigin/uAssets/issues/22151#issuecomment-1909667574

[Agshin2004]

yes, it is, I don't know why but keep filters clean (my filters) solves the issue

[stephenhawk8054]

Yes, that's what I mean

You said

as soon as I import my filters back

so what were my filters that you import and caused the issue. It's this one: https://github.com/uBlockOrigin/uAssets/issues/22151#issuecomment-1910091386 ?

[Agshin2004]

these ones: my-ublock-static-filters_2024-01-25_12.35.17.txt

[stephenhawk8054]

Remove these filters in that file:

! 2024-01-24 https://quizlet.com
quizlet.com##.d3lcmut
quizlet.com##+js(remove-class, has-adz, div.has-adz, stay)

and reset your uBO to default settings

[Agshin2004]

it helped yeah, thanks bud!
