Getting this:

ASSERT: Giving up waiting for the tab closing animation to finish (bug 608589)

Stack Trace:

0:([object XULElement],[object XULElement])

All the time now. It's said to be, "fixed", but, well, there it is.

Anyone else getting said message?

Type in url bar about:config -> hit enter -> confirm Mozilla Security "Bla bla" -> in Filter bar past this text browser.tabs.animate -> double click on search result to switch from true to false-> suppose be solved.

I think Your problem is causing some tab extension, in my case that was Tab Utilities, now I use again Tab Mix Plus dev version and my problem is solved once for good ;)

Hmm, is it just me or does release 19.0 starts spiking CPU usage after a while which causes strong lagginess? One half of a core's usage is in the top 3 all the time and CPU usage of the process is 12-13 of a Quad Core machine.

It was not for me but maybe I didn't use it long enough. I went to the Firefox 20 Beta

It will might solve issue which is more like suppression but if you look at my addons list, it is just three ABP Dev build, Element Hiding Helper Dev build and Last Pass, nothing more but still I get this weird annoyance issue.

It is more like triggered by Firefox tab strip snappiness bug fixing.

In Your case this is kind strange, in my case I was sure that some of addon messed up, any way I've posted this solution as temporary for Users facing problems as Your. I remember from MozillaZine forum a User facing identical problem as Your, in past He have TMP, already uninstalled or disabled, but still problem persist, disabling tabs animation resolve His problem, maybe You have also some old pref in about:config, some rest after tab addon.

GRT ;)

I did do this before, and it does work. Thanks for mentioning it.

That said, I'm always enabling the animations again to see if the problem eventually goes away. No luck yet, though again, the bug is labeled as fixed, so I'm not sure what else to report.

Regarding Tab Utilities and TMP, I've read other reports that are in line with what you said, but I never installed either. Plus, none of the other addons I actually am using have been mentioned, and according to Zlip792, they probably don't really affect the issue anyway. I've left the telemetry and whatnot enabled, so I guess it's up to the devs now.

I made this profile on 1st Feb and I am pretty sure I didn't install any Tab related addon even though I liked your detective skills of finding workaround for this annoyoance. I will surely go with it unless FF dev notice and fix it.

i see they have enabled InContent in UX again which makes me wonder if there gonna enable the new one this week or next?

Addon Style one InContent UI work is not started, a contributor said that he wanna work on it but after one week. So lets hope a new contributor (first time I thin) will help out FF in this.

    • Microsoft making much needed change to Windows 11, 10 Patch Tuesday security updates by Sayan Sen Recently, Microsoft delivered its latest Defender patches for Windows 11 ISOs. These definitions are released from time to time alongside the general security updates available during Patch Tuesday. Speaking of Defender, the company has now announced another important change that affects how security updates are delivered to enterprise devices running Windows. According to a recent announcement, Microsoft Defender for Endpoint's endpoint detection and response (EDR) updates will no longer be bundled with the monthly Windows security updates or Patch Tuesdays. Instead the company is shifting delivery of these updates to Microsoft Update, bringing EDR servicing in line with several other Microsoft Defender components. If you recall, Microsoft last year moved PowerShell updates to Microsoft Update (MU) as well since it provides automatic updates for Microsoft products and services. Thus the move is intended to allow Microsoft to deliver EDR improvements and security enhancements independently of the OS's regular monthly update cycle; this should enable faster deployment of protection updates without requiring organizations to wait for the next Patch release. For those unfamiliar, Microsoft Defender for Endpoint's EDR capabilities are designed to help organizations detect, investigate, and respond to advanced threats across managed devices. Keeping these components updated is critical for maintaining protection against evolving attack techniques. The rollout has already began for Windows 10 devices in late May 2026 (last month) and Microsoft says it will gradually expand support to Windows 11 and the remaining supported Windows versions over the coming months. The company expects deployment across Windows 10 and Windows 11 to be completed by fall 2026 or around Q3 of this year. Once the transition is complete, EDR updates will be delivered through Microsoft Update using KB5005292, provided the required prerequisite updates have already been installed. Microsoft is also introducing a new Defender Update Service as part of the change. Following installation of the first update, devices will automatically create a new directory located at %ProgramData%\Microsoft\Microsoft Defender\Defender Update. Microsoft notes that restarts may occasionally be necessary in case of "rare" failure scenarios. For most organizations, the tech giant says no action will be required as long as Microsoft Update is already permitted within their update management strategy. Admins who rely on manually deployed update packages, however, will need to adjust their processes to ensure the new Defender update package is included. Microsoft also recommends reviewing internal documentation and notifying helpdesk and security operations teams about the updated delivery mechanism to avoid confusion during the transition. As a prerequisite, the tech giant notes that systems must be running Sense version 10.8798.25857.1000 or later and have one of the following Windows updates (or later) installed: Win11 24H2 KB5062660 (2025-07 Cumulative Update Preview) Win11 23H2 KB5062663 (2025-07 Cumulative Update Preview) Win11 22H2 KB5062663 (2025-07 Cumulative Update Preview) Win10 22H2 KB5062649 (2025-07 Cumulative Update Preview) Win10 1809 KB5063877 (2025-08 Cumulative Update) Server 2019 KB5063877 (2025-08 Cumulative Update) Server 2022 KB5063880 (2025-08 Cumulative Update) Server 2025 KB5063878 (2025-08 Cumulative Update) As always, organizations should verify that their update policies align with the new servicing approach before the broader rollout reaches all supported Windows platforms later this year. In case of major problems, the EDR update can be rolled back to the inbox version stored in %ProgramFiles%\\Windows Defender Advanced Threat Protection (ATP) using: MpCmdRun.exe -RevertMde -Product Edr -ToVersion Inbox For those who have access to the Microsoft 365 Admin Center portal, you can view the message here under ID MC1381119.
    • My problem with these smart scopes is that IMO they're not really an entrance into astronomy, they're an entrance to looking at pretty(ish) pictures that you take by essentially pressing a button and letting the scope do the work. I still maintain that getting some binoculars or a solid dedicated telescope (which doesn't have to mean expensive) and actually spending time learning the night sky and using a telescope is a much better way to actually learn. But, granted, the learning curve is a bit steeper (as it tends to be).

    • The perception of Microsoft Edge is unfortunate as it's a world class browser. I'm not exaggerating when I say it's the best browser I've ever used with its feature set, speed, reliability and advanced security. Running the extension Ublock Origin is a must though to deal with advertising and trackers.
