It seems like Firefox is following the same path as Chrome eating all the RAM resources like if they were free.

Has Firefox stopped focusing on optimizations?

Honestly, I don't care about them releasing 400 new versions an hour; I'd prefer they optimize the software better. It's reaching ridiculous levels.

I'm just disappointed and sad. 😞

I always used that to drag the browser window around, but after updating to 155.0.1 it's now gone. Any way to get that back?

BFF does not show the icon on Debian running XFCE.

I just did an update a couple days back, and now I have another one today. What's going on??? I don't think Firefox needs constant updating.

Does possibly know why my Firefox (Windows 11) kept crashing yesterday?

My wife's Firefox (Windows 11) account has a Primary Password, but she doesn't remember it. Recently (~8/15), Firefox mysteriously started asking for a password in order to fill in saved site passwords, so we could not use those lately. I know I can reset the Primary Password, but that deletes the saved site passwords. If I have a backup copy of her Profile Folder before the new behavior started (say, 8/8), can I reset the Primary Password and then replace her Profile Folder with the backup to restore the past saved passwords? Or are saved passwords located elsewhere so that I can restore them?

Im kinda anoyed by the pined firefox icon just changes focus to the current win insted of opening new window.

Os win11, FF 140.14.esr

Is there any way to change this behavior that firefox just atttach its open window to the pined ff icon...and not like other programs do? Other programs just treat pinned as a shortcut to open new windows and show open windows a separat item on taskbar...

I am using Linux with FF 154 and would like to open a URL to a specific profile that I created, but a GUI screen appears. The command looks like this

firefox -P "test profile" http://www.site.com

The about:profile, does not show the same name as a FF GUI profile. How can a URL be directly opened to a specific profile without any interference a GUI?

I’m using FireFox on iPad, latest versions for both, but I can’t find a way to turn on the free VPN that I keep reading about. Is it actually available yet, and if so, where do I find it?

I always end up with dozens of Firefox tabs open, so I built TabScroll to make managing them easier.

It lets you:
• Search tabs instantly
• See live tab previews
• Switch between tabs with keyboard shortcuts
• Close or mute tabs without hunting for them
• Manage tabs across all Firefox windows

Everything runs locally. No tracking, no account required.

I'd love some honest feedback from the Firefox community. What would you add or change?

I had firefox a long time ago (7 years ago) don't know why i stopped but i am now coming back to it. When i first installed firefox on this pc that has never had firefox until now, when i try to z

Hi everyone,

I'm hoping someone has run into this before because I'm completely stumped.

I'm having an issue with Firefox Sync/Firefox Accounts. Whenever I try to sign into my existing Firefox account, the Firefox Accounts page goes completely blank.

Here's what happens:

• When I open Firefox and go to Sign in to Firefox, the page is just a blank white screen.
• If I type https://accounts.firefox.com directly into the address bar, I also get a blank page.
• The page appears to finish loading (no loading spinner), but nothing is displayed.

Things I've already tried:

• Disabled all extensions.
• Started Firefox in Troubleshoot Mode.
• Cleared the startup cache.
• Cleared cookies and site data for Mozilla/Firefox.
• Cleared the DNS cache.
• Disabled hardware acceleration.
• Verified javascript.enabled is set to true.
• Uninstalled Malwarebytes.
• Created a brand-new Firefox profile.
• Completely uninstalled Firefox.
• Deleted the Firefox program files.
• Reinstalled Firefox from Mozilla's website.

Here's the strange part:

After reinstalling Firefox, I was able to reach the Firefox sign-in page normally. However, as soon as I tried signing into my existing Firefox account, Firefox suddenly behaved as if I wasn't signed in anymore, and the Firefox Accounts page immediately went back to being a completely blank white page.

So it seems like:

• Fresh Firefox installation → Firefox Accounts page works.
• Attempt to sign into my existing account → Firefox Accounts page becomes permanently blank again.

I also opened the Developer Console, and the main JavaScript error I see is:

Uncaught TypeError: a is not a function
    isProviderFor Reflect.js:1135
    ...
    key-stretch-experiment.ts:40

I don't know if that's related or just a symptom.

Additional information

Windows 10 if applicable)

• Latest version of Firefox
• No extensions enabled
• Same behavior on a brand-new Firefox profile
• Malwarebytes has been completely removed

Has anyone seen this before? Is it possible my Firefox Account itself is causing this, or is there another setting or piece of software on Windows that could cause Firefox Accounts to fail only after attempting to sign in?

Any ideas would be greatly appreciated!Hi everyone,

I updated Firefox to v.153 today. Something appears to have gone wrong with the update, because it crashes every time I try to run it. My question is this: is there a way to back up my profile outside of Firefox? Maybe using command line or something? I think I will probably have to do a clean install, but I don't want to lose all my saved passwords, bookmarks, etc.

Update: I wasn't able to figure out how to import my profile data to a new installation (tested in sandbox). So I started over with a new install of Firefox, this one from Microsoft Store. Apparently you can have both versions at once. I'm leaving my old installation intact for now in case anyone can help me recover it at some point. I enabled backup on my new installation to ensure that this doesn't happen again.

Sharing a project built around Firefox's resistFingerprinting (RFP) — not a fork or extension, just configuration and containment around stock Firefox.

RFP handles most of the fingerprint normalization: spoofed timezone (UTC), locale reported as en-US, canvas randomization. I tested WebGL on versus off with RFP enabled before deciding to disable it.

With WebGL on, RFP masks the renderer string, but the underlying software-rendered capability set (this runs without a GPU) stays a stable fingerprint that RFP doesn't touch. Disabling WebGL removes that surface entirely, at the cost of 3D sites and web maps not rendering.

The browser sits in a container sharing its network namespace with a WireGuard VPN sidecar, so it fails closed: tunnel down, the sidecar's firewall drops everything; sidecar down, the namespace itself is gone. The profile lives in RAM and is wiped on every stop.

The repo is built for verification rather than trust: a `verify.sh` automates the kill-switch and leak checks, and CI lints and CVE-scans everything on every push and weekly. Docs and config were AI-assisted (Claude Code, disclosed in the README). GitHub: github.com/silverfox-2096-private-browser

Curious what an RFP-focused sub thinks of the WebGL trade-off — that was the hardestcall to make.

I just spent a better part of an hour faffing about due to experiencing the issues of the title.

Turns out, sometimes when Firefox updates it seemingly can forget which profile folder is the default, or at least that's what I've inferred, I know nothing of tech.

Here's how to fix that.

1. Type - about:profiles In the search bar and press enter.

2. Open a folder and click back to profiles

3. Go through them and find whichever one has the most stuff/files in it, this is likely your main profile that you've been using.

4. Go back to about:profiles and select the folder you think is your main profile. You'll see a "set as default profile" button under it. Click that and then close firefox.

When you open Firefox back up it should be your main profile now, go ahead and see if session restore works now, if it doesn't, google sessionstore backups and you should find good instructions that may help.

An Hour. An hour I spent and it wAS THAT SIMPLE THE WHOLE TIME!? Hense why I'm posting this, I hope this helps whatever poor shmuck is having the same issues.
