Remove space in tabs on tab toolbar

more options

Is there a way to "auto" size the width of tabs to remove the excess blank space in the tab title area?

I have tried setting "browser.tabs.tabMinWidth" to 10 but that does not remove the space. I don't know what a lot of the content means in about:config.

I also have a custom css file I am building but I don't know what coding to use in here if nothing works in about:config.

Can someone tell me if this is at all possible or not. If yes, what can I adjust or what lines to use in css file. Thank you.

All new code so what used to work does not. When run 20 Tabs that space shrinks with each new tab added, some have 100's running at the same tame. How they figure that out, no idea.

Not all code is in one place. Search Github or Google Search it and there is a Firefox thread on Reddit.

Someone here may know the code. So it may turn up for you.

So think at worst a reinstall of drivers would be useful if can not find newer ones.

Thank you Pkshadow for taking the time to respond. I think I am asking and expecting too much. I will live with what I see. I have been to most of the links listed with no help- thank you.

For those considering Waterfox - I now have that installed. It is great too. Going forward I am going to use both Firefox and Waterfox for different things now that I know about Waterfox.

Given that the volunteers work hard on both browsers I appreciate everything done and have no complaints for either group. It is still wonderful to have software that is free to use and that my friends is most appreciated.

Thank you!

A kind of "shrink to fit" feature might be visually appealing if it's possible. On the other hand, having all the tabs the same width may make it faster to scan across them from one to the next.

(I guess I normally have so many tabs open that I don't notice any wasted space.)
