Firefox has this really unsolved issue for me where firefox and firefox based forks basically first load through all of my cache which after months of using will take literal minutes and then and only then would my search queries / network requests by browser take place.

That means, to use my browser I have to wait literally minutes and yesterday, it was so long somehow on Zen (I created an issue there but they linked me to the firefox (downstream?) issue which wasn't solved in like sooo many years)

I basically just use a password manager and just create a new profile and start afresh most of the times but still its a little inconvenient I guess.
