FF76 - Hide tab bar with one tab left, doesn't work anymore.

[Centauri39]

I've been using the following script, which, after updating FF75 to 76, doesn't work anymore (in Linux Mint 19.3 MATE 64 bit):

Code: Select all

/*
How To:
1. Find your firefox profile folder : https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data
2. create a "chrome" folder if it doesn't exist
3. Paste content of this gist in a "userChrome.css" file
4. Restart Firefox
Don't hesitate to say if there are bugs, I only tested this for my workflow : I don't use tabs
at all but I want to see the bar if I open a tab by mistake (otherwise I sometimes lose a tab)
*/
#tabbrowser-tabs, #tabbrowser-tabs > .tabbrowser-arrowscrollbox {
	min-height: 0 !important;
}

/* Thanks to @Speravir for making it work again in the latest versions. */
#tabbrowser-tabs tab[first-visible-tab="true"][last-visible-tab="true"] {
	visibility: collapse;
}

/* I don't use tabs so I just hide the new tab button. You should be able to use a similar trick as the rule above with
css siblings selectors if you want to keep it when the tab bar is visible. */
#tabs-newtab-button { 
	visibility: collapse !important;
}

#tabbrowser-tabs tab {
	min-height: var(--tab-min-height)
}

#urlbar-container { max-width:400px!important; }
#search-container { max-width:450px!important; }

and in about:config

toolkit.legacyUserProfileCustomizations.stylesheets

is set to

true

How can I fix this, please?

Unfortunately as Firefox is updated the way you have to target parts of the chrome change. As such, this is not a Firefox bug, so I am moving this to Support.

See if this thread helps:

I replaced the previous code by the one from the 10th post of your link.
Now, that wasted space is gone.
That's very handy especially for small displays like the ones on netbooks.

Great! Thank you!
