I'm using Floorp, a Japanese open source fork, since a week. Much better than vanilla Firefox, you can give it a try: https://github.com/Floorp-Projects/Floorp

Open tabs. I want to see them all, always.

If you are fine with running nightly, maybe multiple tab rows could be helpful

You can easily scroll through the open tabs :) I don't even use the dropdown menu.

What you want is ridiculous and counter-productive, and you should feel bad for even desiring such nonsense.

Having said that - this appears to suggest you're not alone in your self-harming endeavours and proposes editing userChrome.css to achieve it. Technically it is setting a min width to a tab, but <1px would be impossible to display and click on anyway.

As far as I know there is no way to make it exactly the same as chrome, but honestly I think the ways you can do it in Firefox are better, here are some tips:

• you can hover over the tabs and scroll to shift left and right, or click the little arros on either side. It will still always show you what each tab is, and still access all of them.

• the tree-style-tabs extension, it's fairly hard to get into the habit of using and is a big change (I'm still getting used to it myself), but it can make organizing giant tab messes easier. It can be used similarly to tab groups in chrome where you can minimize child tabs

There are some other tab management extensions out there too that you can look further into if you want as well. Hope this helps!

People that keep more than 5 tabs open at a time need to look inward for change :) What the heck are you doing!?

Treestyle tabs is the very reason I am still with Firefox. It’s a fantastic plugin which allows me to indulge on my bad tab management habits.
