This new logo is visible when you enable the Nova redesign on a new tab

I was looking around on the Firefox store and found this one shirt with a very obviously AI-generated background image. This is the only one with a background like this. I don't know why they would use AI art in their shop, considering they clearly have artists. What's your opinion on this? Link

I used firefox from 2020/2021 and back there i didnt really like the browser that much, i had an old HP Laptop from 2009 running Windows 10 at the time, firefox lagged a lot and like in march of 2021 i went to chrome and used until august of 2022 when i got my new laptop i used Chrome there for a month and then i saw the Opera GX ads on youtube that said “opera gx is a gaming browser” and i installed and liked and i used for like 4 years. Back there i installed whatever browser people suggested, now i regret that.

So why i changed to Firefox? I saw some allegations about opera gx being a spyware and owned by a chinese company, and i changed to opera gx as some friends of mine told me that was very good now than 2021, and i installed, moved my stuff to there, and i realized that is so much better and so much smoother than the browser i used, and had more personalization options than opera, i personalized it, installed some extensions that i use and i realized, the cause of firefox being super bugged and laggy in 2021 was because of the pc i used there, now with a even powerful machine i use it with no problems and not of any of those things that i had, also i have lots of laptops, that i use, installed firefox there and logged into my Mozilla account and it started downloading all my personalization settings, extensions, everything!

Of course, there are many features different of opera but i learned how to use them. And i finally can say this was the best decision ever, switch from a supposed “gaming browser” to an real, trusted browser.

Basically the title. After the update to 153 version, as soon I click clear recent last hour history, the browser freezes and crashes. After opening the browser again, all my active sessions/logins in Gmail, Notion, basically everything is reset and I have log in again. Not sure how this version was pushed to public with such bug.

Once every like 10 attempts it is immediate.

seems pretty cool! idk if it's one of the progressive rollouts or if it was added in 153.0

Hi everyone,

I'm not sure if this was caused by a recent Firefox update or if I accidentally changed a setting.

I attached a video showing the before and after.

Previously, when I hovered over the collapsed sidebar, it would expand with a smooth animation. The transition felt fluid, and when I moved the mouse away, it would collapse smoothly again.

Now it feels much more abrupt. Instead of smoothly expanding, it just snaps open, making the whole interaction feel less polished. I still have "Expand sidebar on hover" enabled, but it doesn't behave the same way anymore.

I also noticed that the sidebar now has a dark gray background, whereas before it remained translucent, matching the top toolbar. The old look felt much more consistent with the rest of the UI.

Did Firefox change this behavior in a recent update, or did I accidentally change some setting? If it's the latter, is there a way to restore the previous behavior?

Thanks!

Do you guys think that mozilla would add container tabs for android soon? We really need that feature

Or profiles, at least

It would've better to syncing with pc also

EDIT: I went back to Bonjourr and with some of my sloppy CSS I was able to replicate what I actually want. It would be nice if Firefox would just make a simple switch for it.

I am on Windows 11.

Just moved back to Firefox after using Chrome for the past 15 or so years. I like the shortcuts in Chrome on a blank tab because it gets me to the sites I need quick.

Firefox has the same thing but it just keeps filling with nonsense.

I have dug around other forums and have changed a half dozen different settings in the about:config but nothing has stopped it yet.

I have also tried a couple of extensions like New Tab Tools and a couple others but they either look terrible or don't do what I want.

I don't want to turn off my history as I use it quite often. I like the shortcuts so I also don't want to turn that off.

I just want 8 shortcuts on a blank new tab page and not the other 16 that are just recent random sites I have gone to. What is worse is the random shortcuts start bumping my pinned shortcuts which is weird that I can pin them if they are just going to get bumped around.

This has to be possible right? It is such a weird design to have my new tab filled with random news stories that I have already read, I don't plan to read them again and don't need a shortcut automatically created for them.

Everything else with the move has been great, finding a lot of different things that I didn't have in Chrome that I really like. BUT, every time I open a new tab it is like nails on a chalkboard for my eyes.

I've been experience this very persistent and annoying bug(?) Where out of nowhere, the page will go blank and refreshing the page doesn't fix it. More often than not, I'll just open up another tab just to bypass it, but even then sometimes that tab will be blank just the same as the first so I'll having to just open 2 or 3 extra tabs until it just decides to stop blanking out on me. The main websites I visit are usually just YouTube and Twitch, so it may have something to do with video streaming sites, but I'm not entirely sure as I don't visit many other sites on this device. The tab will often continue running in the background, but the page will remain blank and I can't seem to do anything to reverse it.

Can anyone using Flightradar24 on Firefox tell me if the cursor is still showing correctly when moving it across the map.

The cursor is only showing as the “hand” cursor, not the pointer. I can't select a flight. When I move the cursor across the map, the cursor remains as a "hand" regardless of where I am, even hovering over an aircraft. When the "hand" cursor clicks on an aircraft icon, all it does is toggle the map controls.

Tried Troubleshoot mode to no avail.

Latest Firefox version under MacOS.

Safari works fine.

I have been using Firefox since the very beginning. I switched from Netscape to Firefox back then and never really had any major problems.

However, since the latest update, which was supposedly meant to fix stability issues, Firefox keeps freezing on my PC.

It usually happens when I drag a tab out to open it in a new window or move a tab to another monitor. But it is not consistent. Sometimes it also freezes when I minimize or maximize the window, open a new tab, or try to load a website in a new empty tab.

Sometimes all tabs suddenly turn blank and Firefox freezes. Other times the tabs remain visible, but the browser still becomes completely unresponsive.

I have already disabled all extensions, but they do not seem to be the cause. The problem still occurs.

So far, this only happens on one PC. I have not experienced it on my laptop or work computer.

Has anyone else encountered this problem? Is there a known solution?

Hi everyone,

What exactly is included under "remote improvements", which can be controlled via the "Allow Firefox to improve features, performance, and stability between updates" option?

Is it basically everything that would eventually be included in a future Firefox release anyway, and things like enabling certain features (e.g. the VPN button) through a gradual rollout?

Also, why does "about:support" show the following as active even though I have this feature disabled?
bug-1712189-rollout-keep-firefox-up-to-date-even-when-it-is-not-ru-release-90-94
bug-1766468-rollout-win32k-rollout-release-100-101
bug-1766618-rollout-disable-websocket-over-http2-release-91-100
bug-1802286-rollout-fix-webcompat-shim-breakage-release-103-107

So, in general, would it be fair to say that "remote improvements" are actually beneficial and it's perfectly fine to leave the option enabled unless you specifically want to avoid feature fragmentation between different devices? Or are there any other downsides?

By the way, regarding features... if someone from Mozilla happens to read this:
The marketing team seems a bit overenthusiastic. Release notes often advertise features that don't actually reach everyone until weeks or even months later due to staged rollouts.
That's honestly really annoying. It would be much clearer if features that are available immediately and those being rolled out gradually were distinguished more explicitly.

Thanks in advance for any replies!
Cheers, Martin

Is there any way to enable smooth scrolling on Nightly for 120 hz Macbooks? The regular version of Firefox is very smooth but Nightly is juddery.

Hello, all. It's been an issue for a couple of months now.

Looped YouTube videos do not stop buffering until I click anywhere on the timeline. Clicking anywhere on the timeline fixes the buffering and the video proceeds normally.

With all cookies and site data cleared and uBlock Origin disabled, it still happens.

According to the YouTube stats, there is 0 KB of network activity and 0.01s of buffer health when it happens. There are 0 dropped frames.

I watch videos on 1440p, if the option is available.

uBlock Origin and Enhancer for YouTube are two of the add-ons I always use.

I've been testing it out on this HDR video., but it happens on SDR videos as well. I like looped videos that contain multiple songs within a single video.

How come this happens and how can I fix this?

Thank you for your time. 🦊

I can join a google meet call, then for 5 seconds i can hear the audio, but then it just goes mute making me then have to join on my phone. I thought it was my uBlock origin extension, but i disabled it and it still happens. Here are the other extensions I use.

Hi all,

My machine updated to Firefox 153 this morning and since updating it’s not been able to open, I’ve created a new profile, tried booting into safe mode, uninstalled and reinstalled Firefox but it’s not opening.

The event viewer shows that it’s not being able to open because of microsoft.ui.windowing.core.dll.

Has something changed that requires this? I’ve not been able to find anything about this, I’ve got another machine on 152.0.6 and I’m not wanting to update to 153 just incase it crashes again.

Any ideas?

Trying to block a few websites. I tried with AdGuard’s filters, and while it works with some of the simpler website, I can’t manage to block YouTube and Instagram.

Is there a free or cheap (JFC subscriptions are everywhere) app or extension I could use?

For what it’s worth I’m on macOS.

Thanks!

Can we please fix Sign in bug?

Every time I load up Firefox on Android 16 it doesn't display my email address but instead it always displays Sign in. If I tap on it it exists out fast.

Currently using Edge with most telemetry disabled, standard privacy without 3rd party cookies and uBol for Ad blocking on Android and Windows. I recently tried to play around with Firefox and found the page loading and interaction performance to be the same, if not better than Edge in certain circumstances.

I'm considering a full time switch to Firefox with Ublock, but my main hold back is the rendering engine.

With that being said, how often do you run into sites that just will not work? I'm pretty particular and typically hate duplication of products on my phones and PC, can I get away with ONLY Firefox and never have to use a Chromium browser, or is it just not possible?

Tried:

1) Deleting cookies/cache

2) Going to Firefox's Enhanced Tracking Protection and putting Kick on as an exception

3) Spoofing my Browser Agent (which AI said was most effective)

None of it worked.

I updated today firefox and now is the system background too dark then before. It was more like gray yesterday and now it's extremely dark like black. How can i reverse this? I really don't like this color. Please help me. 🙏

I built Notte because I have a degenerative eye condition and bright websites are genuinely painful for me. It darkens glaring sites while keeping high contrast (WCAG-friendly), leaves sites with a proper dark mode alone, and keeps photos/videos in full color. No data collection, no ads, no subscriptions — free forever. Open source (MIT).

Feedback welcome!

Hey folks, right now im using Speed Dial 2 as new tab. It was my goto on chrome, it is my goto on firefox and you can migrate everything without premium plan. But as far as im aware Speed Dial 2 is not supported on mobile and i would like a completely free alternative that works on mobile and desktop, and it must have some kind of sync (of course automatic one using mozila's service would be awesome).

So any suggestions?
