Just upgraded to Quantum. Now i miss a (for me) very important function: Is it possible to show all open Tabs in more than one row. In TabMixPlus (in the old version) it was possible to make a second or third row to display all open Tabs. Now i have to scroll left and right to find my Tabs. And i h…

The github link to that css tweak seems to have disappeared… Do you still have the file? :sweat:

The file mentioned in the video description is still present: https://github.com/andreicristianpetcu/UserChrome-Tweaks/blob/09fa38a304af88b685f4086bc8ea9997dd7db0fd/tabs/multi_row_tabs_firefox_v57.css

Oh… so it is… Thank you… I was looking at the list at https://github.com/andreicristianpetcu/UserChrome-Tweaks/tree/master/tabs

Drag-and-dropping tabs doesn’t work so well, though, when moving between rows…

Thank you for the video. (And also to Frank Sheiness, who wrote the steps. It was easier for me to follow in writing… :blush:) I have several pinned tabs. When doing your mod the tab rows are all left aligned after the last pinned tab. Any ideas to have the regular tabs wrap all the way to the left…

Great fix, worked like a charm! congrats and thank you, Martin. Do you have any solution to move tabs from top row to any row below it though? I can move (drag&drop) tabs in the top row with no issue, but cannot move them between rows at all…

Thanks a lot. Your links are very helpful. Hats off to your great work. Also, just out of curiosity I wanted to know, what is the use of creating userChrome.css in the end when we have already pasted content in style editor?

Hi, this solution stopped working in FF58.

For new release, it’s needed to replace ‘.tabbrowser-tabs’ by ‘#tabbrowser-tabs’ (at 4 places)

Tabs in two or more Rows (like TabMixPro) in Quantum?

Just restart your browser. It should be fixed. At least that’s what I experienced.
