Fix uBo (network blocking) in sidebar webpages

[trickypr]

@surapunoyousei you might find this interesting. The reason why ads aren't blocked in the sidebar is because the messagemanagergroup is set to webext-browsers on the container <browser> element. If you set it to browsers, it treats it as a regular browser (e.g. no webext permissions, content scripts work, etc).

Depends on #237
Fixes #157

I didn't notice that at all. I never noticed this because the console was giving me an error about not having permissions as a tab.

wonderful. Thank you for the information.

This PR/issue depends on:

If I may be so bold, 🐛 Fix uBo in sidebar webpages (#238) pulse-browser/browser@79f15ee seems to only work with 3rd party builds version, is there a way to apply this change to the official version of Firefox?

[surapunoyousei]

You can edit browser/base/content/webext-panels.js in omni.ja file.

1. into Firefox installed dir.

2. search omni.ja file.

3. Extract omni.ja file use 7zip.

4. search "webext-panels.js" in extracted files.

5. edit the file. search:

browser.setAttribute("messagemanagergroup", "webext-browsers");

replace it with:

browser.setAttribute("messagemanagergroup", browsers");

finish.

move edited file into omni.ja & boot firefox.

Thanks for your pointers🌹

According to the steps you mentioned, I modified chrome\browser\content\browser\webext-panels.js in <Firefox Installed Dir>\browser\omni.ja.

After restarting the browser (Firefox 114.0b2), the messagemanagergroup attribute of the browser element in the sidebar does change to browsers, but Ublock Origin still cannot work on the web pages in the sidebar.

[surapunoyousei]

I will test it.

I think it works. but, cannnot block contents. The blocked ads number is up.

[surapunoyousei]

In Pulse, YouTube Video ads cannnot block. I think this happens regardless of Firefox.

It's a pity

Sorry for asking, but did this really
change anything or are any additional steps/flags required? I tested in floorp and pulse, but didn't notice any perceivable difference in adds blocked or other add-ons (like darkreader) working there. I still have static adds in the sidebar too and can't select anything with unlock in the sidebar...

What are you asking "did this really" for? against my validation? Or on this PR itself?

As I am Japanese, I may not be able to grasp the intentions properly.

Hi @surapunoyousei,
No worries.
I'm referring to this fix ("Fix uBo in sidebar webpages #238) in general, as using releases with this fix applied doesn't seem to make uBo work in the sidebar on my end. It seems like @wordpure is also experiencing these changes not actually fixing uBo in the sidebar.

[surapunoyousei]

I see. We still need to make the addon work in a different way. I research it.

[trickypr]

Hmm... Messing around a bit, it looks like networks requests are blocked but content scripts aren't executing correctly. So, if your ads are loaded via an external script (e.g. adsense) or trackers (e.g. GA) can be easily blocked. But ads that are server side rendered (e.g. search engine ads, youtube's voodoo wizardry) can bypass adblocking.

There are probably some primitives that are missing. I'll open a new issue and work on it eventually.
