Add an option to disable this new "Drag to Pin/Unpin Tab" feature

[TheNickm2]

Since this feature hit my browser after an update a while ago, I'm constantly annoyed by it. I've been dragging tabs all the way to the left to rearrange them practically forever, and now suddenly doing this is pinning tabs that I don't want to pin - I'm just trying to rearrange my tabs.

Perhaps I'm in the minority here, and that's fine - this feature can be enabled by default; however, an option to disable it altogether (via settings or even an about:config option) would go a long way. This feature greatly disrupts my workflows and has proven to slow me down when I'm in my flow state while developing websites. I need this feature to be toggle-able to continue using Firefox as my daily driver browser.

Update 2025-09-29: This feature can now be (mostly) disabled via an about:config option (as of v143.0.3). Setting "browser.tabs.dragDrop.pinInteractionCue.delayMS" to any relatively high value should effectively disable the option. The value is the number of milliseconds before the pin tab option triggers. I set mine to 2000, requiring a full 2s before the feature triggers, which has generally solved the issue for me. I encourage you to adjust this config option to your liking once your browser is updated to at least 143.0.3

Echoing the sentiment to let us disable this feature. I have never wanted to intentionally pin a tab, and certainly don't want it to happen unintentionally either.

+1 to this thread. Please remove this feature, or add option to disable it. Highlight annoying. I used to be able to drag new tabs to left to arrange them towards the middle of the open tabs, now it just wants to pin them instead, and I have to try dragging them to the left without triggering the "pin" feature, and the drag speed is also reduced. If you want to have this new feature, no problem, just allow users to disable it.

It is shocking that this reached production without an option to disable it. Anything less than an option to disable automatic pinning is not a fix.

One has to wonder why this is a feature, since one can right click & select Pin Tab in the first place. 🤔

Agree 300% with Add option to Disable Pinning New Tabs

I had the beta version of Firefox installed (didn't even realize it) and when this feature showed up I specifically uninstalled beta and went to the normal branch (which also caused a whole host of other issues due to a popup constantly showing up about my profile being from a new version).

Now the feature is back in normal Firefox and I HATE THIS! This actively makes the experience worse and annoying, and there doesn't even seem to be an about:config option to disable it (someone PLEASE let me know if there is one) which is surprising cause those are advanced obscure settings. at LEAST give an option in THERE. I've searched everywhere trying to find a way to turn this off and am so pissed off that I can't even modify the files of my browser to turn it off in a "jank" way. For the love of god save my sanity and give all of us a way to turn this invasive, distracting, annoying, I won't even give it the benifit of calling it a "feature. just. . . . let us turn this behavior off, via ANY means necescary, I BEG!!!!

Sad, what lately happenning with Firefox.

I left chrome years ago, because of the new mostly visual developments, which made that browser completely useless on pc. There was a solution to turn it of, but they disabled it later, saying, "we know what you want, get used to it." Shame to see the same happening with Mozilla. First they started with tab groupings, which got solved after a month (thaks god, that was way worse than this).

Before you could turn off these things in Firefox, at least in :config or :studies page. Now I turned off this pinning is :studies, but no success, still making it.

This rollout recommends users to try out pinned tabs as a way to keep frequently used websites within reach.)

Agreed, what a terrible idea, or at least, a terrible implementation. It activates when the mouse is as far right as the 6th icon in the toolbar! Like others here, it keeps on activating unexpectedly while sorting my tabs and I totally hate it. Earlier this year, there was the sidebar revamp that at least I could disable from about:config, but I couldn't find a way to disable this. I might have to switch to a previous ESR or legacy version.

Hello

About the subject, drag and drop to pin.
Have you tried the suggestion https://bugzilla.mozilla.org/show_bug.cgi?id=1984420#c8

---

Found a nice workaround in the meantime though:
Just pin a blank tab. That makes it a bit harder to accidentally pin your real tabs.

@Agentvirtuel 

Yes, that does help, thanks. It's not exactly a solution, but it does mitigate the problem quite a bit.

This new feature is so annoying! There should be an option to disable it.

Hello

https://bugzilla.mozilla.org/show_bug.cgi?id=1984420#c24

Add a setting to disable "drag and drop to pin".

I tested, an experimentation, the value 2000, to see, it works.

Apparently, wait and see the next update, release 143.

[Pingouin]

@Agentvirtuel Actually, if I close Firefox and open it again, the pinned tab is gone, so helps a bit short term but definitely not a long term viable solution.

[Martin89]

Yeah, I really need to disable it as well. Some about:config option at least would be great.

Hi folks, 

Appreciate you all raising the issue. As @Agentvirtuel already noted, we have introduced a preference browser.tabs.dragDrop.pinInteractionCue.delayMS that you can adjust once you update to 143.0.3 that will go live on September 30th. Changing the value of this pref to 1200-1500 is equivalent to turning off the feature. 

You may find some background in the bugzilla ticket, discussing the issue, but the tl;dr is that:

1. We have investigated how the sensitivity for pinning can be adjusted to avoid accidental triggers and yet satisfy people who do want it; however, we found that if the delay is high enough to avoid accidents, it becomes frustrating for people who do want to use drag-to-pin. 

2. Adding an about:preferences setting is a more involved process, as it implies adding the setting, introducing it into various tests, and committing to supporting it in perpetuity. We usually do it if we see a string negative signal (in this case that would be, for instance, significant number of pins end up being unpinned within a minute after being pinned) or, when, in a situation like this, following negative qualitative feedback, we see a significant number of adjustments to the relevant pref (browser.tabs.dragDrop.pinInteractionCue.delayMS adjusted frequently). 

We'll keep track of how the new pref is being adjusted (since we don't see other negative signals at scale), and will consider a more discoverable setting.
