Type about:studies into your address bar to see a list of your studies. Click the Remove button next to the study you want to opt out of.

Hi Agent Virtuel,

Thanks for your reply. It's very helpful and worked right away!

I didn't know about "about:studies". It's interesting to see all my "studies".

Thanks again! - Andre'a

Hello again,

Removing Group Tabs from "about:studies" only worked for a short time. I've tried removing any study that mentions "group" and nothing works. I've made sure to restart the browser so that's not the problem.

Any more ideas??

Hello

For information purposes https://connect.mozilla.org/t5/discussions/help-shape-the-future-of-tab-groups-in-firefox/m-p/95970/highlight/true#M37458 with Firefox 138.0.3, the preference, browser.tabs.groups.enabled is true, by default.

Hi again Agent Virtuel,

I was mistaken. I didn't even try to disable Group Tabs via "about:config" since I'd read somewhere that only the items listed in bold face were able to be reset. Apparently I misunderstood.

After reading the links you provided I decided to give "about:config" another try. It worked!

Hopefully the disabling of group tabs will stick this time.

Thanks again for all you do! - Andre'a
