[Bug] Scrolling of tabs is broken on Nightlies #3605

Closed vflaux closed 3 months ago

vflaux commented 3 months ago

Abstract

Scrolling tabs is broken in Firefox Nightlies since they removed "overflow/underflow events" by disabling "layout.overflow-underflow.content.enabled_in_addons" pref. See https://bugzilla.mozilla.org/show_bug.cgi?id=1907460 & https://bugzilla.mozilla.org/show_bug.cgi?id=1897595

This can be fixed for now by re-enabling the pref in about:config. But the option might be removed one day.

Steps to reproduce

  1. Start Firefox Nightly (since 2024-08-06-21-12-39) with clean profile.
  2. Install TST.
  3. Open tabs until it fill all the vertical space so we can scroll
  4. Try to scroll

Expected result

You should be able to scroll the tabs

Actual result

Nothing moves

Environment

Ditto on:

Can confirm that setting layout.overflow-underflow.content.enabled_in_addons to true (and then false) in about:config seems to bring and persist scrolling within the same browser session, i.e., once the browser is closed and reopened, the scrolling issue remains.

I've also moved the sidebar to the left and right but it did not resolve the scrolling issue.

Have also closed/opened (F1) sidebar and the issue remained.

According to this comment https://bugzilla.mozilla.org/show_bug.cgi?id=1912224#c3, this should be already fixed by this commit https://github.com/piroor/treestyletab/commit/fb01a8ca455735913b495b0323ecffda2853ca73. I tried with dev builds before & after this commit and I can confirm that it fixes the issue. We just have to wait for new a release of TST.

I've uploaded TST 4.0.22 including the fix.
