I'm almost sorry to ask this, but does anyone have experience with Firefox on Linux taking a long time to open? I'm running Pop!_OS on a fairly modern machine. All other programs open pretty quickly, but Firefox seems to drag its feet on startup. Once it's open it's great, no problems with speed.
I have tried disabling extensions (ublock origin, sponsorblock, decentraleyes, i still don't care about cookies) and I have tried setting my default profile as one without any custom user.js (I have a profile with Arkenfox and one with Betterfox's user.js). Nothing I have done so far has seemed to make any difference, but Help->Troubleshoot Mode allows Firefox to open quickly, so there must be something that I can disable that is causing the issue... Any ideas? Thanks.
Edit: Seems like swapping to the flatpak version made things much faster. The Pop!_OS .deb version must be snap like you all said :) Thanks everyone!
Try changing away from Ubuntu to something better, like Mint
Lmao isn't Mint based on Ubuntu also? If you're going to suggest switching distros entirely for slow loading on a single app might as well choose one that's not derivative
Its Ubuntu with all the bloat stripped-out, which is why I recommend it
