under the new nova ui style, settings ui now has a left hand column listing the settings categories available the selected catqgory is highlighted in a light purple color. not a fan. how do I change the color. don't mind collateral damage as not a fan of this color.

After an update (seemingly, I did not run 'sudo pacman -Syu'), the tabs have changed in look and to be frank i find the new layout ugly. How do I turn it back? Attached is a photo of the new tab groups, i couldn't get one of the circular tabs.

I play https://crazyshooters.com/ and https://crazyshooters2.com/ a lot! But the game became laggy since Firefox 148 and my ping spikes up. Other browsers play fine. I am on Linux Mint if that helps. (147 and below run fine)

I have credit card auto-filling enabled and several credit cards active. However, most of the time, when I go to use the autofill, though the card choices appear and I am able to select one, and it usually temporarily shows the fields to be filled, when the menu closes, the auto-fills are gone! It's worse than not having autofill at all. This seems to happen the majority of sites where I try to use it.

A couple days ago when I opened Firefox, I immediately started getting pop up messages saying I had viruses. If I clicked on REMOVE VIRUS, it tried to get me to sign up with McAfee. I cannot see my full screen due to all the pop up screens. My MS Defender virus protection is not identifying any viruses.

I have issues discerning where each of my desktop windows are. To help with this I use gtk.css styling to add a border on all of my desktop windows. For some reason, Firefox does not draw this border.

Is there any way to apply a border around the Firefox window?

I was able to get a border around the navigation area of the browser by adding a userChrome.css file but I don't see any way to do the same thing for the whole window.

Can this be done in userChrome.css? Using gtk.css styling? Any other setting or file?

I am running Firefox 155.0.1 on Ubuntu Linux 26.04.1 LTS using the Gnome 50 desktop.

Hello, I'm pretty tired of Firefox updating itself without asking me or warning me, just telling me that it's going to force me to restart and kill all of my private windows without any chance of continuing browsing. I'd like to disable updates but it seems that they are forced upon the user regardless of choice. Is there a way to prevent them from happening? I managed to disable them on Linux by some miracle but can't find a way to do the same on Mac. I'd also like to remove the little popup that suggests updates every time I open it. No chance of that either? The browser is made for browsing and not for serving the needs of the browser. I really love what Firefox used to be but at this point I might as well switch to something else. The blatant disregard for user experience is what's killing me.

Hello everyone.

Firefox updated today. I don't know—maybe some people like the new design of the tabs, the buttons in the drop-down menus, and the gradient borders around the active tab and the tab bar itself. But I’d like to revert to the old interface. How can I do that?

Thanks!

如题，请问如何跨设备同步标签页群组？ 现在似乎只能跨设备同步已经打开的标签页，但是无法同步标签页群组。

As the title suggests, may I ask how to synchronize TAB groups across devices? It seems that now only open tabs can be synchronized across devices, but TAB groups cannot be synchronized.
