Firefox 131.0 Tabs Hover Preview

Usually every new version of FF surprises me unpleasantly, but 131.0 brought a very useful option that is turned on by default.
If you have several open tabs, it is enough to hover over the inactive ones and you will get a preview thumbnail.

I like it, but you can turn it off if you want.

Type in the URL Bar (Address Bar):

about:config

Press Enter (twice).

In the search field, type preview.
Set browser.tabs.hoverPreview.enabled  to false with two quick clicks on the row or one click on the icon on the right.

If you want to restore the old setting, do the same (set to true).

It is not necessary to become active in 'about:config'.

Under
“Edit--Preferences--General--Tabs” you can check or uncheck the box for the preview.

Yes, but it's not the same.
In your case, the header above the thumbnails remains when you hover over the tabs.

With about:config, the entire option is turned off and we return to tooltips.

Re: Firefox 131.0 Tabs Hover Preview

For advanced users using their own custom userChrome.css  these are the new elements:

/* Tab Preview Thumbnails */

.tab-preview-text-container {
  background: ...
}

.tab-preview-title {
  color: ...
}

.tab-preview-uri {
  color: ...
}

OK, I decided to just use thumbnails.

If you like it, add this to your userChrome.css:

/* Tab Preview Thumbnails */

#tab-preview-panel {
  --panel-border-color: none !important;
}

.tab-preview-text-container {
  display: none !important;
}

Ahh good stuff, and having these options to tweak the thumbnails or turning them off is a great thing. Now FF has what Chrome and MSEdge have had for a while.
