Prerequisites

• I verified that this is not a filter issue
  • Filter issues MUST be reported at filter issue tracker
• This is not a support issue or a question
  • Support issues and questions are handled at /r/uBlockOrigin
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue
  • Your issue may already be reported.
• I tried to reproduce the issue when...
  • uBlock Origin is the only extension
  • uBlock Origin with default lists/settings
  • using a new, unmodified browser profile
• I am running the latest version of uBlock Origin
• I checked the documentation to understand that the issue I report is not a normal behavior

Description

When I open the uBlock "popup" button, the "element zapper and picker" buttons do not switch back to the page. The logger button is useless because it does not open a logger tab. The options button works fine.

A specific URL where the issue occurs

https://github.com/uBlockOrigin/uBlock-issues/issues/new

Steps to Reproduce

1. Press the Firefpx dropdown menu, click uBlock Origin (#)
2. On the new tab, click Lightning, Eyedropper, or Logger

Expected behavior:

typing is painful on mobile. considering Github does not show searching on the mobile site. I switched to the desktop site to search for duplicates, reported an indie on desire site, and now i suffer an unusable auto zoom out.

it works

Actual behavior:

see above

Your environment

• uBlock Origin version: 1.16.16
• Browser Name and version: Firefox Mobile 61.0.2
• Operating System and version: Android 7.0

Was this for the tab already present when you launched the browser? There is a known issue with the first tab, you need to close it and create a new tab. Then all should work fine from there on.

See https://bugzilla.mozilla.org/show_bug.cgi?id=1410749.

This is new:

The logger button is useless because it does not open a logger tab.

Cannot reproduce. Edit: on my beta profile with uBO dev.

[gwarser]

Fresh profile of Firefox 61.0.2

Element picker is working when I switch tabs manually - nothing changed here.
Logger stopped working completely - no new tab, so no way to switch to it.

When clicking Logger and Element picker buttons in popup:

Skrypty nie mogą zamykać okien, których nie otworzyły -> Scripts can not close windows that they have not opened

[gwarser]

Switching dom.allow_scripts_to_close_windows in about:config fixes this partially. Popup closes and Element picker can be used, but logger tab did not appear.

chrome.windows is undefined - this still appears in logger.

I'm sorry for spamming :)

How do you create a new profile with Firefox for Android?

[gorhill]

Well apparently it's complicated. Anyways, Firefox for Android does not support the browser.windows API, so that would be the issue (https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/windows#Browser_compatibility).

How do you create a new profile with Firefox for Android?

I use beta daily, so I tested on fresh stable.

[gwarser]

@gorhill do you think window.open('','_self').close(); can be reverted in vapi-common.js to auto-close popup?

[gorhill]

I rather not remove this one for now, it's just a warning at this point, I don't see it happening with Firefox stable (desktop).

[gorhill]

Ugh.. maybe I misunderstood? This is about the warning in your screenshot above?

[gwarser]

Picker does not close popup on Android - no matter on which tab i use it. Logger button works fine - handled differently?

[gorhill]

Picker does not close popup on Android

That's news to me, I am pretty sure it used too work. Maybe just forcing the target tab to be active after the picker has been injected would work.

[gwarser]

Yes, Popup "tab" disappears when I switch to the "page tab" manually. Problem is - it did not do this just after click on the button.

[nyanpasu64]

@gorhill You can use Island to create a "work profile" aka sandboxed Firefox.

[gwarser]

Thank you, 1.16.17b6 fixed it. Picker still not switches to page when run on first page after Firefox start, but works for other tabs. I assume this is still this Android quirk from gorhill/uBlock#3148

[nyanpasu64]

Thanks for the quick response time.
