Start of Firefox is slow. Startup-Time between 35 seconds and 2 Minutes
Hello,
the Startup of our Firefox is slow on some Machines. With Developer-Tools enabled we don´t see any activity in the Network Tab until the Page starts to Load after 35 - 120 seconds.
What we did to determine the Problem so far:
- disabled Anti-Vir
- Disabled VPN-Client and tried connection via LTE-Hotspot to bypass company Network and Firewall
- Changed DNS to 8.8.8.8 and 9.9.9.9
- Deleted Cache
- Changed Startup-Page
- Disabled Secure DNS in Firefox Settings
- Disabled all GPOs on Workstation and deleted policies.json so no Policies got applyed
- deleted Startup-Cache and enabled secure-start in about:support
- reinstalled Firefox
- changed from up to date ESR to latest Release
- Users Temp and Windwos-Temp deleted
No Problems on another similar Workstation with same Firefox Release.
I wonder if there is any startup-debugging capability.

- Does it still happen in Troubleshoot Mode?
- In Connection Settings change "Use system proxy settings" to "No proxy".
- Reset fonts to default by going to Windows Control Panel > Appearance and Personalization > Fonts > Font Settings > Restore default font settings.
- Set MOZ_PROFILER_STARTUP=1 environment variable to capture a startup performance profile.
Yes, it still happens in Troubleshoot Mode No Proxy setting does not fix the issue Font Reset does not Fix the Issue. Environment Variable: Investigating.
Hi again,
here are the Results of the Profiler while Starting up: https://share.firefox.dev/3TQm7ex
As you can see, the Web-Page starts loading after round about 44 Seconds.
Any Hint on this?

Hi there,
thanks for your effort but we are on windows and pagefilesettings are default.
We´ll have a look at remaining folders after uninstall. Maybe we find smth on Windows too.
After uninstall we´ve deleted %AppData%\Roaming\Mozilla and %AppData%\Local\Mozilla and reinstalled. No Success!
