Firefox randomly slow at startup
Hello,
For an unknown reason, my firefox sometimes is really slow to startup.
It can take up to 10 minutes before the webpage start to load. My hardware is not that bad. I try to use the "performance" to capture the issue : https://share.firefox.dev/3x2rgHj I don't know if there is something to see because, the tool is also slow.
It happens on 3 different computers on linux.
I try to disable all extensions and without telemetry but nothing change. I'm reporting the problem now but it's much older
If you have a idea to fix this issue please share because it's really annoying.
Chosen solution
- In Connection Settings change "Use system proxy settings" to "No proxy".
- Click the "Clear startup cache" button in about:support.
- Try changing widget.use-xdg-desktop-portal.settings to 0 in about:config.
- Keep fonts to a minimum, avoid installing large font packs.

I use the distribution package. I never use the flatpak package.
I may try to see if the issue is present with flatpak.
Hello jonzn4SUZE,
I use Manjaro and Gnome on both of them. One use Wayland and the other two use X11 with NVIDIA proprietary driver.
Before, I used to have Archlinux and the problem was also present.

"Clear startup cache" button seems to reproduce the problem. I was not able to reproduce my issue on an empty profile.
So I suppose startup cache use some cookies and other data. After clearing cookies and data on my other computer, it is better.
So I consider my issue as solved.
