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!
Is Firefox installed as a snap package on PopOS? That could be it if that's your only snap package. I'd recommend installing a Firefox fork that's a regular deb package (Libre Wolf probably?) and seeing if that changes anything
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
I have the exact same issue on PopOS but with Librewolf but not with Brave, so it's related to the engine. Moreover, this bug is funny because I don't know why, but it's related to me being in the exact place. I don't have the same issue when I'm at my family home, but when I'm somewhere other, the issue occurs. It loads about 10 - 15 second. I still haven't figured it out, though. Pacstall also lags when I'm updating.
dpkg -l | grep librewolf ii librewolf 128.0-1 all The Librewolf Browser
That may be because the hostname can't be resolved.
