I am on Ubuntu 18.04 using Wayland session. I installed many extensions trough Ubuntu Software > Add-ons > Shell Extensions to support my daily activities,

but I want to kill some of them because they sometimes slow down the computer, especially when I work with huge programs at the same time.

Is there a way to kill some specific extensions in Gnome Shell temporarily (just for the current session)?

    I am not sure about that method to install extension, I usually install them from the website through the browser. To disable them I then go to Gnome Tweak > Extensions and I disable what I do not want (see imgur.com/rt9TB7o for a screenshot)

  • Thanks. But, I thought 'disable' option will affect the next login session.

  • Yes it will, but it's easier to disable/enable them than uninstall/install via the software center...

Generally speaking, I'm not aware that any GNOME extensions seriously slow down the computer.


Using standard Ubuntu tools, use Firefox (or other web browser) and go to https://extensions.gnome.org/local/. There you can enable or disable individual extensions at will.

To complete the task, restart GNOME Shell with ALT+F2, then r.

You can also use GNOME Tweaks (gnome-tweaks) to do the same thing (except for the GNOME Shell restart).

  • I don't know if it doesn't happen to you. But, they really slow my computer down sometimes. I installed more than 10 extensions, maybe not all of them, but some of them do it, and I don't know exactly which ones. I appreciate your answer, also like @dadexix86 commented on my question. Thanks for it. But I wonder if there is a way to just kill it using command line, because if we disable it, it will affect to the next login session and I want to kill it just for the current session. And btw, restart GNOME shell using that shortcut is not available on Wayland session.

  • @fsevenm have you considered trying to run without Wayland, and seeing how it effects your perceived speed?
