Right now when you navigate to "This Firefox", you can find about:debugging in the list of tabs to be inspected. Should we hide this entry or leave it accessible via a pref for developers?

Summary: Hide the about:debugging tab when looking at this firefox's tab list about:debugging → Hide the about:debugging tab when looking at this firefox's tab list in about:debugging
Priority: -- → P3

After looking at the user testing mocks, I was thinking if we should remote the whole tab section as for me in this-firefox it does not make sense to have them there. It does not serve the purpose of remote debugging as debugging your tabs from your desktop browser is out of scope here and having it adds context as well as a complete topic in the list.

With removing it, we could declutter the page a bit more (and also solve your issue).

Discussed this a bit more on Slack: most of us use Tabs on This Firefox to quickly test things in about:devtools-toolbox.
We could put Tabs for This Firefox behind a preference, that would be set to true for local builds.

Hi! The preference is called devtools.aboutdebugging.local-tab-debugging.

Verified as fixed on Firefox Nightly 68.0a1 (2019-05-14) on Windows 10 x 64, Mac OS X 10.14 and on Ubuntu 16.04 x64.



I really like the option of being able to open the Inspector in a tab instead of a window because I can pin it and make sure I doesn't close it by accident like it happens sometimes in window mode. Also, I can still enjoy having it in fullscreen and easily switch back and forth from the webpage I inspect with ctrl + [number].

So my question is would it be feasible to add an option in the devtools layout menu? (see:

If you think it'd be a good idea to open a separate bugreport (feature request), just let me know. And if it's the case, what would be the appropriate component in the devtools product I should tag it in. Finally, if you know someone I should tag/would be interested to that separate issue, let me know.

Thanks and keep on rocking the free web :).

Hi :sdk, as this bug is closed it is best to file a separate feature request so we can triage and prioritize it. The use case as described is interesting, and we'll have to do some more research to see if and how it fits in our roadmap – which will be reflected in the bug.
