On one macOS Sonoma machine, Firefox launches very slowly and then crashes. On another Mac with the same macOS version, Firefox works normally.

Even in Safe Mode, Firefox cannot start its GPU and socket subprocesses. Steps to Reproduce 1. Download the latest Firefox from the official Mozilla website. 2. Install it normally in /Applications. 3. Launch Firefox by double-click or from terminal. Firefox starts very slowly and then crashes or becomes unstable.

When launching Firefox in Safe Mode: /Applications/Firefox.app/Contents/MacOS/firefox --safe-mode [Parent 1846, IPC I/O Parent] WARNING: Failed to launch gpu subprocess @MachCheckInListener TimedOut (Error:0) [Parent 1846, IPC I/O Parent] WARNING: Failed to launch socket subprocess @MachCheckInListener TimedOut (Error:0) [GFX1-]: Fallback remains SW-WR [GFX1-]: Failed to launch GPU process after 3 attempts

• Reinstalling Firefox does not fix the issue. • Safe Mode does not fix the issue. • The problem appears to be related to Firefox child process initialization (GPU and socket processes). • The browser often starts in crash recovery state. • Automation tests fail with: “Browsing context has been discarded”

Firefox is currently unusable on this machine due to repeated crashes and inability to initialize required subprocesses. • Any recommended workaround or diagnostic steps.

I rebooted my laptop to find that Firefox removed all of my data. I looked up for ways to fix this and then arrived at the conclusion that I could create a profile and set the folder to one of the profiles that weren't listed on Firefox. It seemed to save my history correctly and my saved downloads, but they all said that they were moved or missing. I checked the passwords and instead of the long list of passwords that I normally have, there were only a couple, and the passwords were also sometimes outdated. I cannot recover some of these passwords. I've tried checking the passwords in the other profiles that were listed in the profiles and nothing shows up. None of the cookies were saved either

I had around 3000 tabs open I closed the browser completely today. Normally when I reopen firefox all those tabs were appearing still. This time none of the tabs restored I can see tabs in history part namede 19.01.2026 although not all my tabs are there. When ever I try to reload them from the restore history part; firefox doesnt reply and doesnt take the command.

Hi, I’ve been experiencing slow startup times in Firefox, especially when I have my Time calculator web app open. The browser takes longer to load and sometimes becomes unresponsive.

I’ve tried disabling extensions and changing my home page, but the issue persists. Are there any specific settings or troubleshooting steps in Firefox that can help improve performance when using online calculators like this?

Any guidance or tips would be greatly appreciated. Thanks!

In the pass while on a tab inside a group[1], whenever I 'open link in new tab' it keeps the group closed, but now it forcefully opens the group. Is there setting I can press to stop this.

Good day, I don't know if this is related to the latest version of Firefox that was installed within a few days. When I'm in a "reel" and I click on either the face or the arrow in the circle, nothing happens. Other times when i'm at an item, the same thing happens. I've rebooted my system: Mac Mini (running Ventura 13.7, 3.6 GHz Quad-Core Intel Core i3, 8 GB 2667 MHz DDR4 memory). Firefox V: 147.0.1 I've swapped my mouse with another known to work, with the same problem.

Tonight I ran Facebook on my iPad (V: 18.7.2 - 7th gen.) and everything worked.

Could the updated Firefox have a problem?

i just update my firefox to a new ver yesterday 147.0.1 (64-bit) today suddenly not playing any reels its just stuck pushing play button also dint not help playing the reels

FireFox Tab Groups can remain closed and be re-opened via "List All Tab Groups"

That's why I use FireFox (v146/v147) and not Edge or Chrome

BUT what worked well these last four months suddenly stopped working TODAY, i.e.

 "List All Tab Groups" has disappeared and all I see are tab groups created today

Sadly I never created any FireFox account until a few minutes ago Does that mean those lost Tab Groups can only be recreated manually or is there an easier way ?

( I don't know how to implement jscher2000's script on GitHub )

Will this catastrophe happen every time FireFox auto-updates itself on start-up (v147 since Jan13) ???

Hi everyone.

Basically when the browser is (I think) idle while watching YouTube, FF is constantly backing up (the timestamp in the backup file name keeps getting updated). From the settings page I thought it once every 24 hours. I noticed from higher than normal CPU usage impacting FF and the Windows search indexer. Which reverted to normal once I disabled the backup.

I checked the about config:

• browser.backup.scheduled.minimum-time-between-backups-seconds

Is set to 24 hours (86400 seconds)

But I also noticed:

• browser.backup.scheduled.idle-threshold-seconds

Is set to 15 seconds(!). Is that what I think it is? Back up whenever there's a 15 sec idle window, regardless of the minimum? Can I safely make that 86400 seconds too, or does it do something else entirely?

Many thanks in advance.

All of a sudden my bookmarks and history have disappeared and I cannot add new bookmarks. I have researched this and tried everything I could find to fix - namely restarting FF, restarting the PC, renaming places.sqlite, using task manger to locate which app is locking the file. I also used the Places Database to Verify Integrity and here are the results: Task: checkIntegrity - Unable to fix corruption, places.sqlite will be replaced on next startup > Task: checkCoherence - The task queue was cleared by an error in another task. > Task: expire - The task queue was cleared by an error in another task. > Task: vacuum - The task queue was cleared by an error in another task. > Task: stats - The task queue was cleared by an error in another task. > Task: _refreshUI - The task queue was cleared by an error in another task.

Nothing has worked. Help!

I am running W11 (HOME). FF is acting like I am running W10 (I keep getting info on needing to upgrade to W11).

Now to the real problem:

It appears since I upgraded FF to 146.0.1 64 bit, FF seems to have problems pulling up password/ids that haven't been used for a while. It actually can't find them as if they had never been used. The number of "passwords" it lists is rather small (like 8). This is causing me to have to go through lost password routines.

Any idea what or why this is happening?

firefox suddenly stopped showing any history or book marks. also no history. i've re downloaded, no change. all works well with chrome but i like firefox. and thoughts?

Suddenly, i am finding when i get to the end of my bookmarks and scroll up, the bottom most bookmarks show up. And scrolling down, as i reach the last bookmarks, the topmost bookmarks show up.

1/19/26 I have used Firefox for years and now it looks like Microsoft Bing has taken over and I cannot get Firefox back. It installs to a certain point and stops. Can you help me? email: [edited email from community support forum]
