When I open any stream, it takes about 2.5 seconds from the start of the page loading to the appearance of the stream image and playback. For comparison, in version 137 it took about 1.0 seconds.

I tried to launch the browser (Firefox 138.0.1) in troubleshooting mode, and also created a new profile, but the problem remained.

I also downloaded portable versions: 137.0.1 - everything is fine. 138.0 and 140.0a1 - slow loading.

I also have Zen Browser installed (the latest version is based on 138.0.1) - everything is fine.

This is the link. I can't send animated images as the text is too small, so I'll describe it instead. It's so hard as a loyal fan, I'm crying.https://www.bilibili.com/bold text。There is a bug. Why does the Bilibili website not display the corresponding screen when I try to move to it? Speed playback cannot be used at all, and there’s also the issue of not being able to use fullscreen on Firefox. Are you forcing me to use another browser?

The latest firefox update introduced tab groups, something I've been eagerly waiting for ever since chrome released it!

However, my firefox's tab groups don't hide the tabs correctly. In the video demo I see that when you click on the name of the tab group, it should collapse all the tabs and hide them.

In my firefox, when I click the tab group name, the tabs don't get hidden as expected.

Here is a video that shows the bug I'm referencing: https://imgur.com/a/8ewW1a2

I tried disabling all my extensions and restarting firefox, also tried in private mode, and it still was having the same experience.

Are there any about:config settings that I might have accidentally changed that could be causing this?

Thanks!

Hello, after installing a new hard drive (the old one died and I couldn't recover the data), I reinstalled everything on my PC, except that a friend recommended installing Arium (Windows 10.8 LTS). It works fine, except that now I have no way of connecting my Mozilla account to Firefox to recover my passwords and other saved tabs.

I've searched a lot, tried several installations, and even installed a previous version of Firefox, but nothing works...

Do you know why? Is it because of Arium?

Thanks

After updating to version 138.0, the browser put up an announcement page that informed me that I now have access to a great new feature, tab groups. It's actually a great addition to the browser IMO.

But it's absent. I read the announcement page, then the help page it links to. Every description is inapplicable to my browser, there us no drag-over behavior for tabs, there is no "add tab to new group" option when right clicking. I updated to 138.0.1, same thing. There is a topic in Connect.mozilla.org about tab groups as a beta feature, and it's been up in beta since March. But my browser does not have it.

Granted, the help page vaguely says that no all users will see this feature as it's rolled out gradually until May 6th. But why then tell me that I already have it on update? And why is it rolled out gradually if it's already been in beta?

I just got a new pc, and added Firefox, and also imported all of my bookmarks. But I don't see any way to add tiles to the new tab page. There are no Tiles there, even after 3 days. I really like having the links I visit most listed in tiles on the new tab page. Why don't I have any and how can I add them? I don't see anything the settings, and the help answers don't help because there are no tiles to right click on.

I logged into my Firefox Sync account last week on a newly re-imaged computer. My old computer is listed under "Connected Services" and for the first few days, when I selected "Sync" from the top right menu, the subsequent menu included the name of the the old computer and the list of tabs. That list of tabs is no longer listed and I haven't been able to find a way to access it. Attached is an image of the menu where the list of tabs was previously listed. Any suggestions are appreciated.

Windows 11, v23H2

After the last update, I have a problem opening some links just with a left click. Most open fine, but on some sites, I can open the site fine, but all other links have to be opened in a new tab. Sometimes, I can't even get that menu to come up, so I have to save the link URL and open it in a new tab manually.

I have my browser set to open all tabs in a new window, so that's not the problem.

It's very annoying, especially when I'm trying to get something done quickly.

How do I fix this? TIA
