Is it possible to opt back into a study after removing it?

more options

I found the tab groups more annoying than useful, so I went into about:studies and removed it, but doing so just makes a study entirely disappear with no way to bring it back if you misclicked, so that made me wonder, is removing studies permanent? Is it impossible to opt back in once you've opted out of a particular study?

I'm not particularly regretting my choice in this case, but it made me nervous how easy it would be to lose access to a feature just by accidentally clicking the wrong thing.

If you wish recover Tab groups, take a look at, browser.tabs.groups.enabled

1 - Go to Configuration Editor for Firefox https://support.mozilla.org/en-US/kb/about-config-editor-firefox 2 - Enter a search term browser.tabs.groups.enabled To change a boolean (true-false) preference's value, double-click on the preference. Alternatively, you can click the Toggle button. Try true
