Since Firefox 157 introduced Nova, I’m finding container tabs much harder to distinguish.

With native vertical tabs, the prominent vertical container marker has been replaced by a thin horizontal line. The colours and icons also appear more subtle and less solid. As a colour-blind user, that makes it harder to tell at a glance which container I’m using.

This also happens on a PC without Tree Style Tab installed, so it isn’t specific to that extension.

Container identity matters when separating accounts and browsing contexts. I’d like to see:

• A supported option for a thicker, solid container marker.
• A visible container name or distinct symbol on each tab, so identification doesn’t depend on colour alone.
• Accessibility testing of selected and unselected tabs in both light and dark themes.

For now, setting browser.nova.enabled to false in about:config is a potential workaround, but it changes the broader interface and may not remain available.

Has anyone else, particularly other colour-blind users, found this harder to use? Have you found a supported way to improve the indicators while keeping Nova?

I requested an accessibility review in https://bugzilla.mozilla.org/show_bug.cgi?id=2077901.
If you’re affected, please add your Firefox version, theme, and specific difficulties to the report, especially if they provide new information.

This I dont want to be a post interpreted with wrong intention, but just to explain why I think priorities need to be correct when developing the web browser.

We all know they have been concentrating recently on new marketable features, increased the release schedule to be more agressive to get these features out quicker, but I fear this is going to go in the direction of vivaldi where they just made features everything and the browser became like moving through slime.

The reasons I have downgraded back to 156.

• In 157, I have been noticing when accessing a menu, loading a settings page, whatever it may be it would randomly stall, so there would be some lag before the FF UI responded to what I wanted. I have never experienced before in FF, except only if I tried to that right after launching the browser whilst its restoring the session, and even then it was really slight micro lag.
  
• In 157, loading github web pages, caused the entire browser to stall, scrolling would momentarily freeze as an example, after downgrading back to 156, I can confirm the CPU spike still occurs, but it does not block the Firefox UI or scrolling, the browser does not stall.
  
• In 157, we all know nova was added to the UI, we know for the mean time, it can be disabled in about:config, however there is additional UI changes that were made, that do not get toggled when Nova is disabled, so e.g. the density of tabs in the list all tabs pull down menu, is now much lower, there has been considerable padding added, the text and icons are not bigger, so it isnt to make things easier to read, its simply extra empty space. Someone provided me CSS to fix it, I never got round to applying it though due to all the other issues I was fighting. The devs need to stop increasing padding everywhere.
  

I think fundamentally the problem here, amongst all the other bugs people report, and considering all the problem reports on the bugzilla that are basically just being ignored in favour of sponsored/marketing feature additions, I fear Firefox is losing its way. This happened to me in the past with Vivaldi, it started of with me downgrading the build, then not updating, and eventually led to me changing browser as inevitably the build becomes too old. I am now at the point where I have to back out of the latest build on Firefox, and if I dont see bug fixes for the issues, I will be looking at the Firefox forks to see if they are approaching these problems differently.

This is how I felt Nova dark theme should have looked in default theme. My older themes were also struggling with this update so I felt we need a new one.

I have been using this for few days, I am satisfied with it. Clean, basic and comfortable. Do try!

I swear it used to do this but something changed and you have to press the address bar normally to type.

Is there a setting that can change this???

Just made a custom css theme with more depth. It works best with the atbc add-on together but simple themes work too.

Hi. Been having this issue where when I add a new shortcut to my new tab page, it does either of the three:

1. Defaults to a placeholder letter (like in Google Mail) picture
2. Has the correct image, but has a white background on it
3. Has the correct image and no white background

I like 3, 2 is annoying, but 1 is my main issue. Do y'all have any solutions/workarounds to this?

For some reason, my original post got deleted immediately.

Do note, I am following Privacy Guides' recommended configuration. I've posted a question on Mozilla Forums, and enabling Remember History seems to fix the Gmail icon (but not Messenger or Canva).

Thanks!

Happening for anyone else? I tried it in different browsers and it works but on Firefox nothing happens, my file explorer (Finder since I'm on Mac) doesn't even come up. Only started happening after the update

Hey, has anyone seen this over the last month or so? Example video: https://www.youtube.com/watch?v=TDV-GuZO6Z8.

The video starts, then restarts on its own a few times (the frame counter in Stats for Nerds goes back to 0 each time and the video jumps back a few seconds). Then it ends up at 480p, even on my gigabit connection. If I have PiP open, it gets closed every time.

I use a script that forces 4K. With it off, the video drops to 480p after the reloads. With it on, it can't switch down anymore, so I get a playback error and the video stops.

If I disable AV1 in Firefox (media.av1.enabled = false) so YouTube serves VP9, there's no issue at all.

Fresh uBlock Origin install and wiped YouTube site data didn't change anything, and linux-firmware-amdgpu is current (20260916-1).

Anyone else seeing this, or know a fix?

I'm probably just dumb but I don't understand what this little draggable bar is for. I can drag it up but it just creates a blank space and nothing can be placed in it. I assumed it would be a spot where you could add something into it but it doesn't seem to be the case? Thanks.

Moving from Chrome to Firefox, but my bookmarks are not importing.  I get only one.  And no passwords or anything else either.

Leaving the googleverse, I started out on a chromebook and android phone, starting with movingm to my imac as my daily driver.

So, as the title says

I'm living with this issue for a long time, it's not something that happened with 157.0 and it's getting annoying, I tried the problem resolution mode, nothing happened. I even tried to remove Firefox and reinstall it completely, useless.

I wrote in the Firefox forums, no one could help me out at this point.

Anyone encountered this problem in the past? Any suggestion?

The built-in vpn in my android phone is suddenly gone, any idea how to return it.

I installed the firefox and the vpn shows up but in few minutes it will be gone.

How to get back a past Picture Of The Day I had? Is there a list where I can search for Pictures Of The Day?

It's a small issue in the grand scheme of things, but when you're opening up hundreds of new tabs per month, it adds up. Is this new behavior as of the latest Android version? I disabled my only extension (UBO) and it's still happening after a reboot.

Steps to reproduce

1 - Tap the + sign from anywhere

2 - Cursor/focus goes... Somewhere? But not the Address Bar, like usual.

Basically the title says it, it doesn’t let me download anything at all, can someone help me with solution?

The bookmarks sidebar in Firefox has become too wide for my liking, and dragging the border to resize it doesn't let me make it narrow enough.

I've been having this issue since the latest update.

NOTE: I've already set the UI to "Compact" and disabled the "Nova UI" in about:config, but the Bookmarks sidebar is still way too wide.

What can I do?

Hello everyone,

I use cookiebro extension to manage my cookies and somehow when I whitelist a site I get asked again for cookies allowance the next day or so.

How can I solve this ?

Thanks for the help

The extension used to be THE dark mode extension for low end devices, but now it's even heavier than Dark Reader. It used little memory in phones but now it's a memory hog, worse than Dark Reader.

Does anyone know how to fix this? All of my shortcuts were pinned, not just there because of browser history.

edit: also, my browser history isn't showing up when I type in the textbox, and if I try to edit just a part of an URL it won't stay when I hit enter. Example: if I try to go from reddit.com/r/firefox to reddit.com/r/askreddit by just changing 'firefox' to 'askreddit', when I hit enter the only thing that loads is reddit.com/r/ and I'm sent to 'reddit.com/subreddits' like I didn't put anything in.

Hi,

I am in the process of migrating between systems. I have my desktop with Firefox, I use some multi account containers, I clear cache and cookies on browser close and I have some exceptions to not clear cookies, as I want to stay logged into my accounts. It worked fine on my desktop.

Now, I tried to do the same for my laptop. I turned in account sync and add on sync, my browser settings and containers are indeed synced. But the exceptions are not synced, so I tried setting an exception for some of the sites like my desktop, logged in, closed browser, and I am not logged in anymore. Nevertheless, the exceptions are still remembered.

Some details:

1. On my PC, The exceptions are both in the Browsing Data section and in the History exceptions. So I tried setting the exceptions to both on my laptop too, still no success.
2. On my desktop (where it works), I don't use the "Always use private browsing mode" option, and on History->settings "Cookies and site data" are checked, and "Site settings" is not checked.

Can anyone please help me troubleshoot this? I really don't think it should be that hard, maybe as Firefox updated it became bugged or something?

Thanks in advance.

With bottom bar is sometime hard to hide it or make it appear in some case, need option to hide it with pop up klik button or something better idea in option.

And pull to refresh is so sensitive too, is annoying often incidentally triggers it. Need some adjustment in there too.

I'll cut to chase. Both browsers i mentioned feels stable and clean AF. But one problem is random hiccups when searching for anything and occasionally browser gives up and gives me error like there's no internet. People who know depths of the technical side, please walk me through what settings to turn off or on. I want to have as fast experience close to chromium as possible. Thanks in advance
