Containers graduation from Test Pilot - we still care about 57+

[Jonathan Kingston]

Hi All,

TL;DR - containers is going well, we made it a web extension and it will
continue on addons.mozilla.org

I just wanted to highlight that we have graduated our extension of Test
Pilot Containers to be on AMO: https://addons.mozilla.org/en-GB/firefox/
addon/multi-account-containers/

We have had a few confused users about what is happening with containers.

There is confusion around why the addon doesn't work in 57+ which is due to
it being a legacy addon to support 56, the extension can now be fully
WebExtensions after 57 and to install there you can use: https://github.com/
mozilla/multi-account-containers/releases/latest the addons team is working
on a fix for the website to allow Beta/Nightly users to download there.

We have also removed in Nightly the ability to use the drawer icon which
was native to nightly as it was a subset of features that were provided by
the extension.

To open a container:
- Long press on the + button
- Use the file menu (alt+f)
- Use the extension above (ctrl+period)
- Right click links with the context menu

:bkelly suggested I email here in this bug: https://bugzilla.mozilla
.org/show_bug.cgi?id=1402342 which provides further clarification.

We have exciting posts coming soon to explain further, I just wanted to
highlight we aren't dropping containers just clearing up experiences for
when 57 is stable.

Any user of >57 can actually install any container addon to enable
containers:
https://addons.mozilla.org/en-GB/firefox/collections/jkt/container-addons/

In Beta and Stable releases containers is still disabled by default,
installing a container addon will enable them. To reduce confusion here I
have raised: https://bugzilla.mozilla.org/show_bug.cgi?id=1402608 to allow
users of beta/stable to enable containers through about:preferences also.

If in doubt feel free to reach out to: conta...@mozilla.com

Thanks
Jonathan

Thanks Jonathan.

Also, it seems the link to the web extension version of the container addon
is broken above. This one works for me:

https://github.com/mozilla/multi-account-containers/releases/latest

Sorry, I guess this isn't a web extension yet. Its a legacy addon and
therefore disables multi-e10s.

[Andrew McKay]

Sorry, it disables e10s even though it has
<em:multiprocessCompatible>true</em:multiprocessCompatible> in the
install.rdf? That shouldn't be the case.

[Ben Kelly]

It disables multi-e10s. Forced to one content process.

[Andrew McKay]

Just to close the loop on this thread, in 57 this will no longer
disable multi-e10s.

Thanks for the heads up Ben.

Also AMO is accessible to 57 users to download from there instead too :)
