My Firefox sync stopped working after the latest update. Bookmarks are not syncing between my desktop and laptop. I have tried signing out and back in but it still does not work. Any suggestions?

Anyone succeed with running Firefox in headless mode under Ubuntu?

I tried:

firefox --headless --safe-mode -P headless https://quan.hoabinh.vn

but got this error:

[12545] Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM

• • • You are running in headless mode.

[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt

I installed Firefox as from "https://packages.mozilla.org/apt" repo.

Hello all, I have FF 152.0.6 in use on Fedora 43 xfce Qubes OS VMs. The only issue I have encountered is when I try to load the web UI for Proxmox Datacenter Manager. As soon as I log in to the web UI Firefox vanishes. I have tried this in troubleshooting mode with the same results. I can open the same web UI in a Debian 13 Qube and it works perfectly. The FF version there is v.140.13.0esr. These are simply the default versions that come with Qubes 4.3 templates. I can also access the web UI in the original Fedora Qube with Chromium browser with no crash. I have also tried a different Fedora qube with the same failure result as the original.

I can use Chromium but would prefer a streamlined experience with just one browser. I thank all of you in advance any thoughts or suggestions. I am a long time Firefox and Mozilla user.

Have a great day. SS

After updating Firefox to the latest version, my bookmarks are no longer syncing across devices. I have Firefox installed on Windows 11 and Linux, and the sync was working fine before the update. I have tried signing out and back in to my Mozilla account but the issue persists. Any help would be appreciated.

I have used Firefox since version 1.5 and have loved it and the community since. However, since finally scrapping Windows and switching completely to linux, Firefox has been frequently troublesome with random crashes. The crashes occur on any website I may be on and for seemingly no reason. It happens when I'm in the middle of browsing a page, just opened a new tab, or even when Firefox is simply open and I'm active on another open application.

Environment is as follows:

OS: Zorin OS 18 (Latest patches) (Based on Ubuntu) Mobo: Asus Crosshair VI Hero (Latest available BIOS) CPU: Ryzen 9 5900XT GPU: EVGA GeForce RTX 3080 XC Gaming (10GB) Ram: 8GBx4 G.Skill TridentZ RGB DDR4 (3200) Sys Drive: Samsung 970Evo M.2 Nvme 500GB

Firefox is installed via Flatpack through the built in app store in Zorin OS.

The crashes will sometimes be constant as well. Such as when it crashes, crash reporter comes up, then I click "Restart Firefox" and the second I see the window, it crashes again. This has been a constant problem though at random times ever since I switched back to Linux about 5 months ago.

Any help would be greatly appreciated. I don't want to have to change my primary browser from one that I am generally so happy with, and is also the browser that I recommend to everyone.

Hi I noticed that some old links in my history are automatically deleted. How to configure expiration rules (if possible) in order to keep links forever, until manual deletion? I know that links can be saved in the bookmarks, but when browsing the Internet, unless bookmarking everything :(, no one knows if a link can be useful in the future.

Thanks for your help

This started since Firefox 153.0 (Debian package).

When I open Firefox for the first time after a reboot, it opens my latest tab but all the other tabs on that window are lost, and they show as "ghost tabs" as seen in attached image.

No other issue, other windows are preserved properly when I Ctrl + Shift + N

Sometimes, the bookmarks toolbar disappear and the history list became hidden for no clear reason. Then, after I reboot my laptop and log in again, everything is back to normal.

Hello I am using Google Flow on my Linux PC and when going to edit scenes I get an error about a missing Codec. If I use Brave browser works fine so this makes me think this is not an OS issue but browser.

Hi,

last year I deleted my paypal account. Before that I deleted all entries and connections to abonnements in paypal. A few days ago i received an e-mail from Mozilla that I should pay my VPN abonnement. I would like to do so, but after logging in, I was shown an error message: "Invalid payment information. There is a problem with your account. Manage payment method."

When I go to "Manage payment methods," no options for other payment methods appear, only a PayPal link. What should I do now?

Thank you for your help!

I am using Firefox on a LLinux Mint 22.3 - MATE 64-bit operating system.

Recently, I went to www.homedepot.com. The page did not fully load. It just kept trying to load the page. I waited for a few minutes and tried to do a search for an item I wanted. I got a message that indicated: "OOPs! some went wrong. Try refreshing the page."

I tried refreshing the page. I got the same situation. The page would only partially load and each time I did a search, I got the same "Opps!" message.

So, I went into setup and deleted my cache. This did not help. I also uninstalled Firefox and reinstalled it. That still did not help.

I started up Google Chrome. I went to the site and it worked just fine. So there is something wrong with Firefox.

Hello Mozilla VPN Support,

I recently purchased Mozilla VPN and installed it on my system using the Flatpak version.

My operating system is **Linux Mint 22.2**.

The problem is that the VPN connects successfully to any server, but after a short time it disconnects automatically. This happens with every server I try.

Interestingly, if I use the Mozilla VPN browser extension, it works correctly and stays connected. However, the browser extension does not provide access to all the countries that are available in the full VPN application.

Could you please help me determine why the Flatpak application keeps disconnecting and whether this is a known issue with Linux Mint 22.2 or the Flatpak version?

If you need any logs or additional information, I would be happy to provide them.

Thank you for your assistance.

Kind regards, Nikos

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!
