Removing Preview Hover

Firefox 浏览

I want to disable the Tab hover preview and I follow the instructions per Mozilla Support, which are:

Enter about:config in the address bar and set browser. tabs. hoverPreview. enabled = false.

When I enter about.config and search for "set browser. tabs. hoverPreview. enabled = false" it comes up as false. And there doesn't seem to be a need or way to save that setting, already set to false. But it still has the hover preview.

How do I get rid of the preview mode?

Thanks. Dennis dennis@denniswilder.com

You've misunderstood things slightly. You need to change browser.tabs.hoverPreview.enabled to false; the word "set" doesn't come into it and nor are there spaces after the full stops. I suggest you cut and paste this line into about:config.

browser.tabs.hoverPreview.enabled

In about:config true/false values auto-save instantly.
