Firefox Community Forum

I recently logged back in to my Firefox account that I hadn't logged into in about 3 to 4 months and all my passwords and links in the sync part are completely gone that took me years to setup. Is there any way of recovering them? Where did they do? I am positive I did not delete the account sync information. I would greatly appreciate any help in this matter.

I have multiple devices all using Firefox with the same account. On one of the devices I swapped the motherboard and since all payment methods in firefox disappeared. Syncing is active across all devices. On all other devices the payment methods are still available.

On the device with the new motherboard, I tried to disable payment methods sync and re-enable it but the payment methods list is still empty. How can I restore all the payment methods on this device? Why they are not syncing?

Thanks

This is Firefox 142.0.1 on Windows 10. I prefer to have a local copy of the Firefox profile saved to a USB stick as a simple backup and for copying to another PC if necessary. I have been doing this for years, but now I am unable to do so because Windows gives me an "access denied" error for all of the files in the top-level profile directory. I cannot even open them in Administrator mode. If I try to copy the profile directory as described in your help pages, it says that I need permission from the account that I am logged in as in order to access the files! I have been using Windows since version 3.0 and I cannot understand what Firefox has done to make the profile inaccessible to everything but itself. Obviously, Firefox is able to read the files without additional permissions, so why can't I?

I used to have the camera and microphone on video conversation using the instant messenger on Firefox browser, but now it says "camera and microphone not supported by browser". So I tried to fix it thru setting, privacy & security, accessibility - camera & microphone, but no joy. Can somebody plese show me how to fix it. thanks.

Every time I am using Firefox to login to an app that requires a passkey (which is many now), it says I will be asked to provide my passkey and no window pops up.

The browser freezes and I have force quit it.

Judging from other comments and questions, this appears to be a bug. Please fix it as it renders Firefox unusable.

I'm using Firefox for Mac v142.0.1

10 September 2025

I'm used to use the sidebar history to open previous links for a variety of reasons. You used to be able to click or middle mouse click the links to open the tab in the current or a new tab. But it seem now i can only left click the links and it opens them in a new tab regardless. Right clicking only allows you to open the link in a new tab or a new (private) window.

Is there a way to fix this? Please help.

Thanks

Hi Mozilla team!

IRecently started using firefox/mozilla exclusively on my mobile phone and HP laptop.

I have an AT&T yahoo email account which I have had for 20 years.

No problem on my mobile, but my email history wont re-sync on my HP laptop at this time, but does display as historically synced, BUT ONLY TO May 4, 2024 (for an unknown reason.)

I currently get to AT&T yahoo email account using:

• https://mail.yahoo.com/n/inbox/priority?.src=ym&reason=myc&accountIds=2
• Mozilla or Firefox Username: bernardjfrazier@snet.net,_
• Mozilla or Firefox Display name: bernardjfrazier
• Mozilla or Filefox Password: Argus01!!##

Can you please help me with why the email account won't e-ync on the HP Laptopeven though I am logged in? There is no such problem with gmail.

Thank you,

Bernard Frazier

Ubuntu - I use the SNAP version of Firefox - I generally have lots of tabs open but only use 5 or so of them and it's generally fine.... but when I am closing Firefox, it USES like 100% of the CPU and ALL of the RAM and ALL of the SWAP memory when closing.

This locks up the computer.

Sometimes it doesn't quite go all the way but I can watch it all happen in real time, using Task Manager - and that shows a solidwall of all resources occouring, when the close Firefox is run.

I am told by research via ChatGPT that this is a very real problem with the SNAP version and it's best to change to the Debian version, copy all the bookmarks etc., across and then uninstall the SNAP version.

It's rather disconcerting to have Linux crash because of this one app locking it up and frequently.

Chat GPT:

Is there a problem with Firefox Snap Version closing and using all the resources while doing so, which results in locking up the computer?

You're definitely not imagining it—there have been reports of Firefox's Snap version consuming excessive system resources (CPU, memory) and even causing lockups or hangs, particularly during closure. Here's what’s going on and how to mitigate it:

What’s Happening with Firefox Snap?

2. Browser Hangs or Locks the System on Close

On Linux (especially Ubuntu), users have reported that closing Firefox can lead to it hanging in memory, sometimes unresponsive and still consuming resources.
Super User
Ask Ubuntu
A stark example from Reddit illustrates the severity:
“About 50% of the time I open Firefox, it'll reach 100% CPU usage in about 30 seconds… PC completely unusable unless I shutdown.”
Reddit

3. Known Wayland Sway Bug

On Wayland/Sway setups, reloading Sway while Firefox is open can trigger intense logging, causing high CPU use and an enormous syslog.
Fix: Set MOZ_DISABLE_WAYLAND_PROXY=1, or upgrade to FF 125 where the issue is addressed.

Alternative Approach

Many users, particularly on Ubuntu, opt out of Snap completely in favor of the .deb package or PPA builds. These alternatives often avoid these specific issues. Ask Ubuntu Reddit
