Tab previews are annoying

[thaliel]

I really do not need or want anything popping up when hovering my mouse over any tab. It should be easier to entirely deactivate the tab previews

[Luca_Pavan]

I disabled this new unexpected feature easily on the settings but actually the tab title and link is still being previewed 😑.

"browser.tabs.hoverPreview.enabled" disables the two line hint, but unfortunately it keeps reverting each time I start firefox.

I had to put a user script user.js into my profile folder
user_pref("browser.tabs.hoverPreview.enabled", false);

it fixed the problem for now

For quick reference, here is a screenshot of the checkbox that controls whether to show the thumbnail image. This doesn't remove the second line from the tab hover tooltip. There is help on that further down in the discussion.

The tab previews are annoying to me as well, especially because they draw attention from the web page, where I want to be focused.

I see a lot of replies on how to work around the browser, but I think there should be a plain simple setting to disable the tab preview altogether. I hope a product manager/designer will see this thread.

I see no benefit in that feature so I wanted it turned off. Since I could not find anything in Settings, I tried browser.tabs.hoverPreview.enabled to false in about:config. That disabled the feature (yay!) but next time I restarted Firefox, the feature is restored and the setting resets to true. This is a bit annoying since I have to do that every time I restart Firefox.

Maybe, you are under Studies

Type about:studies in the address bar
The tab will open

Yay! Worked! Thanks a lot!

I don't have it, and have to disable "browser.tabs.hoverPreview.enabled" every time I start Firefox 😞

See DrVint's post above.

Chrome introducing them, but without the ability to switch them off, was one of the reasons I now use Firefox.

I accept that what's annoying bloat to me is somebody else's useful feature so if I can switch it off I'm happy.

Firefox's settings really do need an overhaul.  There are several things in about:config, about:profiles &c that should be normal user settings and others in bizarre places.

It appears the Tab Hover "study" has ended and now this super annoying feature is permanent. Please get rid of this or at least give an option in Settings to disable it permanently. Right now I've disabled the tab image preview in settings but there should be a preference to disable the link preview as well. Instead I have to go into configuration every time and manually select browser.tab.hover.preview - false, but it reverts every time Firefox is restarted! Please include a fix in future update!

It's annoying and unnecessary.

DrVint's answer above gives a way around it not sticking.  This is how to implement it of you don't already know how.

Open Notepad, or whatever text editor you like, and enter this:—

user_pref("browser.tabs.hoverPreview.enabled", false);

Save it somewhere easy to find and name it user.js.

In Firefox type about:support into the search/URL bar. Look down the blue block on the left of the screen that will open until you come to "Profile Directory". Click the "Open Directory" button next to it. This will open your Profile Directory in Windows Explorer, or whatever file browser your system uses.  Drag the user.js file you made into it.  As a precaution right-click it and choose Properties and make sure it's really called user.js and not user.js.txt.  Rename it if needed.
