Description

Original discussion here: https://www.reddit.com/r/uBlockOrigin/comments/dpnpk8/ublock_possible_automatically_closing_tabs_when/

New tab is closed by matching popup filter when opened by middle click or Ctrl + click.

uBO had protection to not close tabs when opened directly by user: gorhill/uBlock@7713597

This stopped working after gorhill/uBlock@f204d24

$ git bisect good && ./tools/make-chromium.sh

I added a test, no. 14, to detect this kind of regression: http://raymondhill.net/ublock/popup.html.

[uBlock-user]

add ||netdna-ssl.com^$popup,third-party to My filters
middle click on http://ffp4g1ylyit3jdyti1hqcvtb-wpengine.netdna-ssl.com/opendesign/files/2019/06/FX_Design_Blog_Logos_Family.jpg

Can't reproduce on my Nightly, it's a week old version.

Can't reproduce on my Nightly, it's a week old version.

uBO version? Tested also on Firefox beta Version 71.0b6 Build ID 20191031113544

It's fixed.

[uBlock-user]

uBO version?

1.23.1b15

[gwarser]

Also with test 14 on http://raymondhill.net/ublock/popup.html ?

[uBlock-user]

Also with test 14

Yes, with ||example.com^$popup,third-party

logger never shows popup entry..

[gwarser]

Maybe somehow related with this about:blank entry? I don't see it in Chrome.

+0	/adhandler.aspx?$popup	--		3,3	popup	http://example.com/AdHandler.aspx?
+0					popup	about:blank

Filter: /adhandler.aspx?$popup
Filter list: EasyList

---

Try latest Nightly? If it does work in beta try bisecting https://mozilla.github.io/mozregression/

[uBlock-user]

It rather show example.com/adhandler.aspx, as new navigational entry in dark grey border.

It's okay, it's one of those times where something is working as expecting without a fix, it's rare but it's good and the fix is already implemented, not worth investing time in mozregression...

[gorhill]

The link at example.com is https://www.iana.org/domains/example, the URL of the final page in the new tab is https://www.iana.org/help/example-domains, so there is a mismatch between the link and page URL in new tab, thus it will be considered a candidate for popup filtering.
