Firefox slow to open
First time posting here, I've been using Firefox for years with no problem but over the last year or so (I can't remember exactly when) firefox starting taking longer to open.
It's not taking forever, only like 6 seconds, but it used to be instantaneous, as every other program on this pc is and it's bugging me. The window opens immediately but it's all greyed out, nothing loads and the blue mouse wheel spins above it.....again, only for 6 seconds. Specs: i9-9900k @ 5Ghz 32GB RAM Windows 10
I've tried every step in https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems this guide, no effect :-(
