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 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

uBlock Origin breaks "Open image in new tab" when there is a rule to block popups.

A manual "Open image in new tab" should not be considered the same as an automatic popup and should not be blocked, the same way as "Open link in new tab" is not.

A specific URL where the issue occurs.

https://bato.to/title/81559-skip-beat-official/2492793-ch_299
https://hentai2read.com/a_former_brave_resident_in_the_dungeon/ (nsfw)

Steps to Reproduce

1. Go to one of the example urls
2. Rightclick any image and chose "Open image in new tab"

Expected behavior

The image should open in new tab and stay open.

Actual behavior

In Edge a new tab briefly flashes and immediately disappears.
In Chrome, it doesn't even flash briefly, it just never opens.

uBO version

1.60.0

Browser name and version

Edge 130.0.2849.56
Chrome 130.0.6723.92

Operating system and version

Windows 11

Can you open new tab > reproduce the issue and on that page > click on uBO icon > 💬 Report button > scroll to the bottom > click on Troubleshooting Information and copy paste it here?

do you have easylist filters enabled when trying to reproduce it? the rules that block popups on the example sites are part of easylist.
the "block all popups" button you highlight at the start of your video is not required for reproducing the issue (but should not hinder it either).

[stephenhawk8054]

I'm using default settings.

This EasyList filter is causing the new tab to close:

/^https?:\/\/.*\.(jpg|jpeg|gif|png|svg|ico|js|txt|css|srt|vtt|webp)/$popup,from=...

Unfortunately uBO doesn't know that the tab was opened using a context menu entry, that information is not available to uBO. Not something which can be fixed.

AdGuard and ABP also suffers this issue.

The issue does not exist on Firefox because the event listener onCreateNavigationTarget() is not called in Firefox.

#932 talks about middle-click which i can not test, however it should be the same as ctrl+click or "open in new tab" for links instead of images, which works fine here. Either things have changed in the four years since, or maybe its just in that specific "Cent" chromium derivative.

And it was actually asking for an easy way to temporarily allow a popup, not to fix how the $popup filters work (if you say this is impossible). I think that's actually a reasonable idea/alternative. Perhaps something like the browser's built-in popup blocker which iirc showed an indication for the blocked popups in the address bar and you can click it to allow/open a specific popup that was blocked. Or, if uBlock Origin is able to see the modifier key state at the time the popup is opened, perhaps allow them if "Ctrl" is being held, or similar.

I'd go as far as to suggest uBlock can probably remove the built-in "Open image in new tab" if its code is such that its impossible to distinguish from automatic popups, and replace it with its own menu item with code that sets a flag or uses a way to open a tab which can be distinguished. Or are extension APIs so limited that even that is impossible now? (I know that was the trend things were going but I'm not aware how bad it's gotten yet)

Not something which can be fixed.

suggest uBlock can probably

Whoever thinks it's possible to fix can submit a PR. I prefer people prove me wrong with a PR than me having to spend a lot of time to explain why suggested ideas don't work.

@garry-ut99 all those are about opening normal links in new tab, which actually works now.
edit: I mean it works on the sample pages above which have $popup filters applied to them. IDK what "no-popup switch" is in comparison and if opening links in new tabs also works with that.

i added fix in uBlockOrigin/uAssets@cc49b9f as i see valid content is blocked
regarding the above regex filter ,EL has been informed
