GNOME and Mozilla Discuss Proposal to Disable Middle Mouse Paste on Linux (linuxiac.com)

Some projects keep surprising me with their “solutions,” and this is one of those cases. A proposal under review by developers from GNOME and Mozilla could change how middle-mouse-button paste behaves on Linux and other Unix-like systems.

The discussions, visible in Mozilla’s Phabricator revision D277804 and a linked GNOME gsettings-desktop-schemas merge request, focus on disabling the traditional primary selection paste by default.

Mozilla proposes changing the default behavior of the Firefox browser on Unix builds so that pressing the middle mouse button no longer pastes text by default. The author of the revision frames the current behavior as a source of confusion and accidental pastes, especially when users press the middle button without expecting the clipboard contents to be inserted into text fields.

Mozilla’s Phabricator revision D277804

The proposed change just stops setting middlemouse.paste to true by default, and there are comments suggesting tying it to GTK's corresponding preference.

GNOME merge request: Disable primary-paste by default

People that know about this functionality and really love this functionality can easily override the setting.

gsettings set org.gnome.desktop.interface gtk-enable-primary-paste true
