Why has FF 131.0 broken multi rows again!!!...stop breaking Multi row or implement it into the browser.

Every update seems to break multi rows. Please stop doing this will you or implement it in the browser.

I have the same complaint. FF, either stop breaking one of the best reasons I use FF, or build this feature into the product!

Same here.

Honestly, the ability to get multi-rows is a key reason that I am loyal to Firefox, and they are working really hard on getting me to move to a different browser. Add it as a first-class feature!

Okay slight over-reactions here guys, its a CSS snippet hack. UI changes. I've fixed it in 5 minutes by adding `flex-wrap: wrap`:

You can see what I changed in the latest commit at https://github.com/replete/firefox-userchrome
```
scrollbox[part][orient="horizontal"]{
    display: flex;
    flex-wrap: wrap;
    overflow-y: auto;
    max-height: calc((var(--tab-min-height) * var(--tab-block-margin,0px)) * var(--multirow-n-rows));
    scrollbar-color: currentColor transparent;
    scrollbar-width: none;
    scrollbar-gutter: stable;
    scroll-snap-type: y mandatory;

       /* This selector is the fix: (copy this part into the relevant place in your own userChrome.css) */
       > * {
          flex-wrap: wrap;
       }
}
```

I am fed up with this too! How stupid must one be to design this endless one-row-**bleep**?! I want my multirows back!

Re: Why has FF 131.0 broken multi rows again!!!.

Ulv — Fri, 04 Oct 2024 20:07:34 GMT

Build it into the browser! It is inbelievable it is still not integrated yet!

Re: Why has FF 131.0 broken multi rows again!!!.

Ulv — Fri, 04 Oct 2024 20:08:48 GMT

But is it safe?

Re: Why has FF 131.0 broken multi rows again!!!.

Ulv — Fri, 04 Oct 2024 20:10:31 GMT

Nice, but unfortunately not working with FF 131. I had this line already in the old userChrome.css and it stopped working. So just "flex-wrap: wrap;" won't do the job!

Re: Why has FF 131.0 broken multi rows again!!!.

replete — Fri, 04 Oct 2024 20:10:32 GMT

It's literally a one line CSS fix, the CSS multi tabs you have has nothing to do with Mozilla

Re: Why has FF 131.0 broken multi rows again!!!.

replete — Fri, 04 Oct 2024 20:13:52 GMT

Definitely working here with whatever version of multi tabs I put in my repo. Depends what snippet you are using I guess.

Re: Why has FF 131.0 broken multi rows again!!!.

tajkkj — Fri, 04 Oct 2024 21:10:46 GMT

Bingo! The flex-wrap: wrap; change worked for me after I deleted an extra close brace "}" that had been lying around since 2020, I think. Anyway, I now have my multiple rows back. Thank you very much replete.

Re: Why has FF 131.0 broken multi rows again!!!.

Ulv — Fri, 04 Oct 2024 21:28:37 GMT

No, it is no use inserting this line unfortunately.This may have helped in older versions of FF as I find this line even in my old userChrome.css from 11/2022 (!).It did work until the Update to FF 131.

Now multirow is broken - no matter if i use your script with all the 9 files or my own ccs-file from 2022.

replete — Fri, 04 Oct 2024 22:26:29 GMT

I just realized my git push to https://github.com/replete/firefox-userchrome failed, so the fix wasn't in the repository until just now. The fix has now been pushed and I've pulled to my Windows machine and confirmed the fix has resolved the broken multi-row tabs on Firefox 131.

Effectively though, if we're using the same version of multi-row tabs, adding this would fix it:

scrollbox[part][orient="horizontal"] > * { flex-wrap: wrap; }

Potnoodleman — Fri, 04 Oct 2024 22:07:07 GMT

I use this but I don't want to keep relying on it just in case the guy who makes it, doesn't update it one day.....still annoying though

Ulv — Sat, 05 Oct 2024 07:22:54 GMT

Many thanks, Mr. replete :-).

Aktually I can confirm it is working now! Multirow is on air again.

May God be with you!

P.S.:

I did not get that

"> * {
flex-wrap:wrap;
/* Fix for Firefox 131 */
}"

was not the same as the already existing line " flex-wrap: wrap;"

Probably not. Many of the prerequisite links will not traverse properly. There is a certificate issue.

I use https://github.com/MrOtherGuy/firefox-csshacks, I've got that cloned to my chrome directory, so I only needed to `git pull` and it started working again 😉

If you are a firefox-UI-CSS expert - perhaps.

For the other 99.999% or users and 99.9% of power-users - not at all. 🙂

I use https://github.com/Aris-t2/CustomCSSforFx . It's a great repo, but because it has so many things it can do, and because multi-row-tabs are supported well, but are turned off by default, I only pull it when Mozilla breaks me, which is regular, but infrequent. So every time it happens I have to waste an hour trying to remember what I customized, and how to apply it to the changed repo to restore roughly the previous I state had.

Mozilla, you guys are claiming to listen to your customers and to try to offer differentiating features. Make multirow-tabs a first class citizen!

Here is a pre-configured set of settings for Aris-t2's CSS mod:

It sets up multi-row tabs with fixed with. See screenshot on the linked page.

Hi,

exactly, i use FF mostly of this feature, but there are some others too like customizing colors etc, and also not that big friend of chrome, but i have a feeling that the current devs of FF are really young guys they dont know about Netscape, and im afraid if they works against users they will end like Netscape.

The simplest firefox multi-row tab groups solution:

Mozilla should implement multple-row tabs into firefox indeed!

Please make multirow tabs a builtin in feature. I have tried several patches but eventually gave up on multirow fixes because firefox updates keeps breaking them.

The multi-row tab script, MultiTabRows@Merci.chao.uc.js, still WORKS, on Firefox 145, 146, and 147, even supports the upcoming Tab Split View & Tab Stacking features. 😼
