Yes, follow the instructions here:

Hope it helps.
In my case, it just shows a black rectangle :( https://fedia.io/media/f0/18/f0180aa24497689d44b0e199a6e0617f8a6628f12466257fb10dfeda004629e4.png
That tab you are hovering is “special” (because it has a protected domain addons.mozilla.org, there are a couple of them ) addons can not inject content so i assume generating a screenshot also wont work here.
Also the addon wont be able to generate previews if the tabs are discarded, so the tabs need to have been active at least once in the current sessions, otherwise there also wont be a preview available.
Thats what i gather from my own knowlege and from this issue https://github.com/easonwong-de/Tab-Preview-On-Hover/issues/1
tldr;
- Some protected domains wont have previews (addons.mozilla.org)
- unloaded aka. discarded tabs which havent at least once been active in the current browser session (restored as unloaded) wont have a preview either.
Hope this info helps.
It didn’t work on the google search page either :(
Is it working for you?

Well … in my case the hover cards dont show up at all. The tab image generation seems to work, from what i can see when i debug the capture loop, so i assume there is some issue with the CSS theme.

If you have show read posts disabled, there’s currently a bug where it hides your own posts. I think a fix is in the next release.

The download link of CSS theme doesn’t work. So I created a folder chrome and pasted the text into a userChrome.css file.
But it just shows a black rectangle :(Did you toggle on toolkit.legacyUserProfileCustomizations.stylesheets? Firefox stopped parsing userChrome.css by default since several years ago.
Yes I did… Is it working for you?
Do you mean this setting?
Nope I’m not taking about windows taskbar… I want to see the preview when I hover over a tab… see gif
