12/22/23 - Firefox Takes 10 to 15 Seconds to Start
Just recently, within the last two weeks (today is 12/22/23) Firefox it taking a long time to start. Firefox version is 121.0 (64 Bit) Windows 11 Home Ver: 22H2, OS Build 22621.2861 This is a reasonably new Acer Nitro PC (August 2023) with a solid state drive.
When I double click the Firefox Icon a large white box opens on my PC and remains that way for 10-15 seconds, then the white box fills-in with the Firefox screen. Once opened, Firefox works perfectly.
I tried the troubleshooter and Firefox starts instantly, as it did previously. I have no Extensions, Themes, or Plugins. I even disabled: OpenH264 Video Codec and Widevine Content Decryption Module. I tried Google and DuckDuck as the Search engine with no difference.
Any suggestions?
Thanks for your help.

Does it still happen with hardware acceleration disabled?

So it does not happen in Troubleshoot Mode?
Visit about:support in the address bar and try clicking the "Clear startup cache" button on the right side.
Good suggestion! I cleared startup cache and it made no difference, it still took 10-15 seconds to start.
I also just tried Troubleshoot Mode again and Firefox starts instantly. I also double checked that there are no Extensions, Themes or Plugins. There are none!
I tried Microsoft Edge to check if the start-up delay is related to out internet connection. Edge started instantly!
I am ready to to uninstall and reload Firefox, I'm hesitating because I'll loose all my bookmarks.
Any other suggestions?

Thanks for your suggestions:
I disabled Hardware Acceleration and now Firefox starts instantly. However, I did not previously set or alter this setting. So why is it suddenly causing a problem?
I also looked at Accessibility Services and found: UIAUTOMATION|C:\Windows\System32\EoAExperiences.exe. Even though disabling Hardware Acceleration seems to work, I'm going to disable EoAExperiences anyhow.
Thanks for the help.
Merry Christmas, Paul
