Fx57:tab list arrow not visible

[Diorser]

Hi,

I've noticed something strange on Fx57 tab bar: the "tab list arrow" is only visible during customization.


Normal mode:


I confirm this with a fresh profile, with several open tabs.
Do I miss something obvious ?

It appears when the tab bar can't fit all opened tabs and switches to overflow mode with scroll buttons at the left and right end of the tab bar.

Ok I see. More than 24 tabs need to be opened on my screen to see this arrow, and even more if browser.tabs.tabMinWidth is set to 50 or less.
Is there a trick to get this arrow visible much earlier, or always visible ?

[GHM113]

It is possible to make this arrow always visible using .css tweaks. Try this code:

Code: Select all

@namespace url("https://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); 
#tabbrowser-tabs ~ #alltabs-button { visibility:visible!important; }

Type about:support in the address bar - Enter - Open folder
Create chrome folder, create text file inside it and rename it to userChrome.css
Open userChrome.css and paste the code above
Restart the browser

I already have userChrome.css and userContent.css, and your proposal works fine !
Thank you.
