How do I change the minimum tab size?

Firefox 59 changed the user interface. One change ruined the Tab Bar for me, making it unreadable by reducing the minimum size of each tab displayed across the top of the screen. When more tabs were open than could be displayed, as many as 60 black square tab buttons could appear across my 27 inch iMac screen, the native resolution of which is 2560 x 1440. Back then it was several weeks before I found a developer in the community who could explain how to resize the buttons in the Tab Bar.

Then recently I was having a problem with malware forcing (or trying to force) me to link to an ad before allowing access to a chosen link. There was a workaround, but sometimes this forced redirection was legitimate. So I fixed this problem by running Adware Doctor. Unfortunately, in addition to fixing the malware problem, that reset everything to the default state. Changing the tab appearance back from white-on-black to black on white (active) or black-on-gray (inactive) was easy. But I have forgotten how to resize the Tab Bar buttons since it requires entering actual numerical horizontal and vertical dimensions in a specific location which can only be accessed by entering the proper code, again in a specific location. In other words, programming. So I need help.

Do you mean this pref on the about:config page?

  • browser.tabs.tabMinWidth
  • /questions/1198099 I HATE the new v.57 tab bar; how do I go back to the old one?

If you want to change the height of the Tab bar then you will have to use code in userChrome.css
