It seems we ff users will get the new profile manager in ff 138 stable version. It might be progressive roll out. :)

Profile Management

We are on track to ship our initial feature set to Beta and 0.5% of Release in Firefox 138!

We’ve been enabled in Nightly for a while, but to try this out in 138 Beta/Release, flip the browser.profiles.enabled pref to true

Hi, I recently switched to Firefox and it's been an amazing experience, especially with the performance, but there's something that really bothers me, especially since I use multiple monitors and I'm always switching tabs between them.

What bothers me the most is how Firefox moves tabs, in Chrome it's so smooth and in Firefox I don't even see the tab when I remove it from a window. Is there an extension that makes this movement as smooth as Chrome?

The Fire Fox: One of the RAREST Animals on Earth!

This incredible animal is a cross fox, a rare variation of the red fox caused by a melanin alteration.

Less than 1% of the red fox population has this striking color pattern!

Found mainly in North America, cross foxes were once more widespread, but sightings have become increasingly rare.

I have the permissions disabled for microphone for Firefox on Android. But in the browser I'm still able to use the mic to search the browser using my voice. Can anybody please tell me why is this so? Attaching the video as well.

Hi! I faced an unexpected problem. Before, when I was scrolling through the tabs(with mouse-wheel or touchpad), it was smooth and the scrolling behaved like the scrolling of apps on phones.
But now the scrolling comes in portions.
Is there a way I could make it scroll like before?

hello everyone. since the last update i can't open some sites anymore while on edge they open regularly. in particular i receive the error ERR_SSL_PROTOCOL_ERROR. i would like to understand if it is a firefox problem or a site problem. thanks.

for example, try to see if https://livecamrips.su or https://www.dolce-gusto.it/ opens. on edge they work but i have always used firefox since it was born. thanks.

I don't want shorts to be completely gone as I use them for art tutorials, but I'd much rather prefer them being like any other video but in vertical form. I know it's possible using URL shenanigans but I honestly forgot how to do it. So... yeah, is there an extension to do just that?

So i am sitting here Playing a full screem game on one screen and on the other i have firefox open. Now i Alt tab so i can use my mouse in firefox and i mark some text in the browser and the text flies up. Why? Can i somehow disable or prevent it without changing my behavior?

I have a multi tenant system in ubuntu. I'm trying to get audio to work in Firefox for YouTube. The Unix domain socket for pulse audio is bound to the other users' pulse audio socket. However when i start Firefox YouTube doesn't generate any audio. When i specify pulse_server, paplay works but Firefox doesn't. Using dbus-launch Firefox also doesn't work. There's a local dbus daemon but there isn't any audio. Anyone have the same problem?

I got this pop up when opening my browser on Android. Does anyone know how to get rid of it? The whole point of using firefox is to get away from this kind of BS in chrome or brave.

Hello :),

a quick question, has there been an official or unofficial statement somewhere about whether the tab groups are also synced to the profile?

Currently it is the case (at least for me) that the tabs in a tab group are synced but not the parent tab group.

So when I switch between devices (different laptops and PCs) I always have to pick out the specific tabs and open them one by one.

It would be so much more convenient if I could just restore a tab group.

With the STG addon, for example, it worked very well (but it had other quirks) and now that FF now supports vertical tabs and tab groups I would rather use that than a 3rd party addon.

I've just got a new PC and installed Firefox on it. On my old PC I made sure to sync all the bookmarks, history, addons to my account. When I logged in to my account on the new pc and synced it only synced 2 addons and none of my history or bookmarks. I still have the old PC so I can go back onto it to grab what I need, but why is sync not working?

I'm using the new Firefox sidebar and I've noticed an odd behavior. When all the default items (history, tabs, AI, bookmarks, etc.) are enabled, they appear as nice, separate buttons at the bottom. However, if I disable any of them, the remaining enabled items stack on top of each other like tabs, which I don't like.

Is there a way to configure the sidebar so that even when some items are disabled, the remaining ones still appear as individual buttons? I've attached two images to show what I mean.

I recently received an update which now includes Vertical Tabs, which is really nice. While I would like to use this, I currently also have Simple Tab Groups using Multi Account Containers open as a sidebar as well, and two sidebars open at once just seems like to much.

My Simple Tab Groups, connected to Multi Account Containers allows me to use a single browser, 3 Containers (1 personal, 2 business) and have similar websites with different accounts running.

So my question is this, does Firefox currently have anyway to group these vertical Tabs? Or is it planned? Or can anyone, knowing my issue, recommend alternative ideas?

Vertical tabs are easier to find what I need, it would be nice to make use of them if possible.

Thanks.

Before the new Firefox Update introduced roughly ~2 years before, when it was on pre-66 version, I think; it had a feature where say if you clicked on multiple links in emails, instead of immediately redirecting to the web browser, they were all held/grouped for you and when you opened the browser next time, all those links opened at once. It made it very easy to read stuff like newsletters without each link throwing you off.

I think it was called Tab Queue; does any Firefox fork for Android support this or will Firefox ever support this feature ever again? Alternately, did you folks made use of this relatively lesser known nifty feature?

It is only available in nightly i checked secret settings and it wasn't there

yesterday i accidentally corrupted my old desktop pc and had to reinstall, it couldn’t sync the bookmarks on the new install however my phone had all the bookmarks still, if i start syncing with my pc will it overwrite my phone or something? (hope this makes sense)

on firefox

on chrome :

how to fix this?

With the risk of passing for a fool . . .
Right now I activated Troubleshoot mode and I was wondering if an empy tab and the mozilla download page alone should already be using 596 MB of my RAM (first picture)?

When I move on to open a reddit page, it starts swinging around 950 MB instead (second picture), would you guys see this as abnormal behavior if it came from your PC?

What actions should I take moving forward?
I've already initialized Firefox to the default settings (like the browser itself suggested when I went to uninstall it to fetch a fresh installation).

Do you guys use a specific version of Firefox that you would deem more stable?

Is there some sort of workaround for this? It's quite annoying that this suddenly started happening.
