It can be 👍
I also didn’t have a need for it and wanted to disable it and I found browser.tabs.hoverPreview.enabled
in about:config
(set it to false to disable).
There’s also browser.tabs.hoverPreview.showThumbnails
to only disable the image preview but not the new layout of the tooltip (there’s also a corresponding option for it in the main settings)
for anybody that wants to disable it, go to the settings and search for “Allow websites to perform privacy-preserving ad measurement”
(or through the
dom.private-attribution.submission.enabled
flag inabout:config
)https://support.mozilla.org/en-US/kb/privacy-preserving-attribution
