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.
Okay. I could spend hours and hours criticising GNOME for a lot of things, but this is not one of them. It is not removing functionality, as the article implies; as others here highlighted, it’s simply changing a default. That’s completely fine.
No default gnome app will be able to toggle that default. You can hack it in gsettings.
And worse, the fact there is a setting means that only the default will be tested. The feature will slowly but surely bitrot. In a few years we’ll see a proposal to remove it entirely. This is how software development works.
