browser.tabs.cardPreview.enabled revert back after closing the browser

Since "browser.tabs.cardPreview.enabled" is set at "true" in the user.js file, it overrides what is in about:config.

You need to edit manually user.js.

With the Search tool of your code editor, look for "browser.tabs.cardPreview.enabled" (it should be around lines 280-290, depending on your Firefox UI version and variant.)

If you don't have a code editor, you can use Notepad.

Also, for some general information, here is an article describing more in details the tab preview feature : https://www.omgubuntu.co.uk/2024/02/firefox-devs-working-on-tab-hover-previews

you're absolutely right. I completely forgot about the user.js file, I'm a layman with zero experience in these things, it is not really an excuse, but accept my sincere apology for the inconvenience I made.
