Reoccurance of 'Fixed' bugs
I updated from Fx for Android v121.0.1 to Fennec v136.0.0 and noticed a dramatic negative change to scrolling through tabs. In v121 Already poorly distinguished vertical vs horizontal swipes lead to unintended closing of tabs got way worse in v136. (Thumbs are anchored to a pivot point on the stationary hand holding a phone and so vertical movements include some curved, horizontal direction).
To reproduce, open multiple tabs (>16) and in thumbnail view ( not tested in list mode), hold device in palm and use same thumb to swipe up and down through tabs.
Actual results:
Tabs regularly mistake arc of thumb movement to be a horizontal, close tab action.
Expected results:
Scrolling vertically. Tabs not assuming swiped closed.
There are multiple 'fixed' versions of this error on bugzilla so I can't comment on 'resolved' bugs like:

The Bugbug bot thinks this bug should belong to the 'Fenix::Tabs' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Hey Jack,
Thanks for reporting this bug! Although the fix in Bug 1904906 seems that it landed in 136, the fix was actually behind a feature flag, which was only enabled to ride the trains, starting from 137. See Bug 1944681. A new update is coming on April 1 (137 will become release) so can you please test again in a few days?

Fennec not updated yet; I'll test when the update lands. Meanwhile, thanks for the reply.
Marvellous! I can confirm that 137.0.0 fixes this problem.
Thanks! 😁
