Latest Stable Firefox, windows, over 4000 tabs. Overall Firefox works great for me. but when I restart it to install the latest versions etc, it only restores one active/loaded tab per window. Rest are restored, but in a closed/unloaded state. I usually have 5-20 open tabs per window, and hundreds more unloaded, it's how I work. How on earth can I get it to restore all the open/loaded tabs as they were, not in the unloaded state they default to?

Issue still occurs in a new install with no addons, default settings, under 30 tabs etc. Ditto Win 10 or 11.

Also, how on earth can I get official Mozzilla pages to use Dark Mode??

I don't know what happened. I must have hit the wrong button but I can't get back to what I had. This is a nightmare. I forced quit Firefox and restarted but it did no good.

would it be possible for me to save a whole window for a later date. this window has multiple groups and tabs. I'm looking for something like the recently closed window but it is there permanently for when i want to open up that window again?

Hi All,

I had several tab groups. I open and save and close them every day. but since yesterdayI cant find them at all. If I create a new tab group it appears but those old tab groups not! I've tested troubleshooting mode but noting.  

Firefox 154.0 (aarch64), macOS 26.6.2.

Hi,

Now when I do a Command N, a new browser window is opened, but I always get the same dozen or so tabs that open. This did not use to happen and I do not recall changing any settings.

I can close all those tabs, close the window, and when I open a new window again, that tabs are all back.

Thanks so much, Charlie

PS Yes. It's driving me crazy.  :-)

How can I make sure the Vertical Tabs sidebar stays visible in full screen mode?

It worked this way by default until the [154.0 release](https://www.firefox.com/en-US/firefox/154.0/releasenotes/#note-792047):

> Fixed the Vertical Tabs sidebar staying visible in full screen mode. It now hides along with the toolbars and reappears when the cursor moves to the edge of the screen.

Is there a config setting that re-enables the old behavior? I want the address bar to be hidden in full screen mode, but not the Vertical Tabs sidebar.

Tonight when I launched Firefox, I started getting everything opening in a new window, rather than a new tab, which is what I have indicated in settings and have always had before. Even if I drag a tab from a new window to a previous window, I cannot close the tab. All I can do is close the window.

I have vertical tabs turned on. Say i want to watch a movie, i press F11 or fullscreen to open it fullscreen. It makes the whole page fullscreen, but the vertical tabs remain still on the left. I want that fixed so that vertical tabs are hidden when its fullscreen.

Trying to get stuff done. It's hard when you start a task in one tab ,switch to another tab to start another task, and when I switch back to the first tab, it hadn't completed the task, it actually paused when I left it. What's the point of multiple tabs, when only one is working at a time? I expect it to continue with the task, while I go elsewhere to complete a different task.

This should be simple. Your site sends a message saying do I want to update MY TABS WILL BE RESTORED. It DOES NOT say I need to go through history and check forums and consult outside parties. I'll keep this in mind the next time a silly tedious update comes around.

Previously all my tabs would launch when I opened Firefox. Recently it has stopped doing so. Only one tab opens. All the other tabs I use frequently do not open. Why is this? How do I have all my tabs open when I open Firefox

Hi, I was a heavy user of the multi-account containers extension. Since FF now has that functionality built in I disabled the extension recently (more than a week ago). My company keeps FF up to date - currently on 153.0.3 aarch64

All tests have been performed with other extensions (ublock origin and auto-reader view) disabled.

Since the last update (last wednesday I think, 5th. Aug.) I've been unable to access the AWS or Azure portals from a container tab, though it works correctly from the 'bare' browser.

I've cleared cookies and site data for the whole browser (made no difference)

I've cleared cookies and site data for the container tab - this now allows me to sign into Azure (which is a prerequisite to signing into AWS), but AWS is still blocked with a microsoft message "We cannot sign you in, try a different user name"

If I use the bare browser, no container, I can sign into the AWS SSO portal correctly.

What can I check to help diagnose this? MacOS Tahoe 26.6.1 Firefox 153.0.3

regards

Chris

I discovered tab grouping and find it moderately useful. There was an update, now I cannot group and tabs. They simply will not. Spent a few hours with ChatGPT trying a range of things. Al settings are right for tag grouping, but it simply does not happen.

I am unable to press new tab or even use Command T to open a new Tab. The New Tab button seems greyed out as if I've hit the limit for tabs, but I don't have too many tabs open. Not even the keyboard shortcut is working which quite surprising. I am able to create new tabs if I open a new window, so I am not completely unable to create new tabs, but i was just curious as to why this might be happening to my current window.

The plus sign to add a new window has disappeared. I search and went into Customize toolbar but there is no option to add the + sign back in. This happened previously and I was able to fix it. Now I can't. What is going on? what are you doing with firefox to make it so difficult to use. NOW I have to use chrome. I have been a loyal advocate for firefox for decades!

It seems I can no longer set a link to open in same tab. There is a Government webskite that won't let me open a link in a new tab and I can no longer find a way to stop a link being opened in a new tab
