Why does my FireFox take so long to load?
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!
If you try to open FF using the terminal does it give you any error messages?
Good suggestion. What does this mean? [Parent 4226, Unnamed thread 762a7e8fd280] WARNING: Failed to set scheduler settings: Operation not permitted: 'glib warning', file /builds/worker/checkouts/gecko/toolkit/xre/nsSigHandlers.cpp:187
(firefox:4226): GLib-CRITICAL **: 20:17:36.507: Failed to set scheduler settings: Operation not permitted
From the what I have read it seems like this is a Gnome error causing problems for software.
