  • I can't get that workaround to work. I have a notepad file in that folder I created with the code

    @namespace xul url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);

    min-width: 12px !important;
    max-width: 40px !important;

    why don't it work?

    do I need a different program than notepad to create a css file?

    edit: yes u need to use notepad++
  • Since this plugin isn't working in FF 57, there's workaround.

    Minimum tab width may be specified in about:config option browser.tabs.tabMinWidth. Though FF would ignore values below 50 px.

    To make thin tabs you would need to use userChrome.css setting (see instructions: https://github.com/Aris-t2/CustomCSSforFx).

    To specify min and max width for tabs you would need to add the following lines in userChrome.css (min width in example is 12 px, specify your own values):

      min-width: 12px !important;
      max-width: 120px !important;
  • An excellent addon - without it having lots of open tabs is much more troublesome.
    Hopefully a FF57+-compatible version will be available soon...
  • All,
    to change tab width manually on 57+
    On your profile, create a folder called chrome/userChrome.css

    and inside it, this (change the values to what suites you)

    .tabbrowser-tab[fadein]:not([pinned]) {
    max-width: 250px !important;
    min-width: 40px !important;
  • plz update to ff57
  • It's the most useful extension...
  • It does not work in the latest version (57) please update the plugin, it is really useful.
  • Fantastic app, works very well. Incredibly useful, since I often have a ridiculous amount of tabs open in one window.
  • This extension does nothing on Mac Firefox 53. No matter what number is set in the extension's dialog or in the about:config option that it creates, tabs are still the same width as before, forcing the hateful scrolling behavior that cripples the Firefox UI.

    The person who ruined Firefox's tab behavior by removing tabMinWidth is the same person who offers this extension, and who justifies his sabotage of the browser's usability by citing this extension. The fact that this extension does not work completely undermines that justification.
  • Since 2004 i work with mozilla, and this addon help me with work in mozilla. thanks :)
  • from the previous review: use about:config
  • No issues. One weird thing: it doesn't let you set a max width above 1000 in the preferences. If you want to set something higher than 1000 you can go to about:config and search "tabs.tabMaxWidth" and change that to whatever you want. I set the max width really high so that I would get Safari-style tab widths.
  • The add-on works nicely on Firefox 49. And the right button on tabs works as normal as well.
  • Wish the instructions were posted!

    There's no right-click functionality or keyboard short cut -- but I wish there was.

    Change the tab size by going into your Three Bars Menu, Add-Ons, Custom Tab Width, then Options.
  • Never had it break; using it in Firefox 46 with no issues.
  • This doesn't work properly for FF 44. I cannot give a short size to tabs, I have to see always the titles of them, and I just want to see the favicon.

    This is a shit add-on. Delete ir and give us back the possibility to change it by firefox configuration.
  • Dão Gottwald, the creator of this add-on, is the same person responsible for the removal of "about:config" settings that let you customize tab widths. See for yourself: https://bugzilla.mozilla.org/show_bug.cgi?id=574654

    Now that's one more extension just to fix his mess...
  • Just what I needed. Thank you so much for this. Short tabs were last thing which Chrome was better in.
  • Always working faithfully
  • Works and rocks
  • I recently came back to Firefox (40.0.3) after several years with other browsers, and I found I'm no longer able to adjust minimum tab width with about:config. This add-on restores that very useful function.
  • No need to restart. No unneeded things. Just simple and working.

    P.S. This website is awful, but it's not your problem; it's Mozilla's problem.
  • works
  • The max tab width setting will not allow me to type anything that does not start with '10', which appears to be the minimum by text.
    For me, this is a useful addon for using themes that set a really small min tab width.
  • Worked perfectly before Firefox 29, now it still works, but as Firefox no longer seems to take browser.tabs.tabClipWidth into account, there are no close buttons if the tab width is below 140px(the default), even if usually they are. A workaround for this is to use stylish or userChrome.css to set this:

    .tabbrowser-tab .tab-close-button{display: block !important;}
