<h1>Legacy QtWebKit backend</h1>
<span class="note">Note this warning will only appear once. Use <span class="mono">:open
qute://backend-warning</span> to show it again at a later time.</span>
<p>
You're using qutebrowser with the legacy QtWebKit backend. It's still the
default until a few remaining issues are sorted out. If you can, it's
strongly suggested to switch earlier, as legacy QtWebKit has known security
issues and also breaks things on various websites.
</p>
<h2>Using QtWebEngine instead</h2>
<span class="note">This is usually the better choice if you aren't using Nouveau graphics, and
don't need any features which are currently unavailable with QtWebEngine (like
the <span class="mono">qute://settings</span> page or caret browsing).</span>
{% macro install_webengine(package) -%}
You should be able to install <span class="mono">{{ package }}</span> and start qutebrowser with <span class="mono">--backend webengine</span> to use the new backend.

{% macro please_open_issue() -%}
If you know more, please <a href="https://github.com/qutebrowser/qutebrowser/issues/new">open an issue</a>!

QtWebEngine is only available in Ubuntu's repositories since 17.04, but you can <a href="https://github.com/qutebrowser/qutebrowser/blob/master/INSTALL.asciidoc#installing-qutebrowser-with-tox">install qutebrowser via tox</a> with <span class="mono">tox -e mkvenv-pypi</span> to use the new backend.

<h2>Using QtWebKit-NG instead</h2>
<span class="note">This is a drop-in replacement for legacy QtWebKit.</span>

There are unofficial QtWebKit-NG packages <a href="http://repo.paretje.be/unstable/">available</a>.

No easy way is known to install QtWebKit-NG on your system.
There are unofficial QtWebKit-NG packages <a href="http://repo.paretje.be/unstable/">available</a>, but they are intended for Debian Unstable.
{{ please_open_issue() }}
{% elif distribution.parsed in [Distribution.arch, Distribution.manjaro] %}
With an updated <span class="mono">qt5-webkit</span> package, you should already get QtWebKit-NG.
{% elif distribution.parsed == Distribution.gentoo %}
There's an unofficial <a href="https://gist.github.com/annulen/309569fb61e5d64a703c055c1e726f71">ebuild</a> available.
