I'm looking for ways to speed up Firefox because it's really slow and frustrating to use. I want it to open faster and use less RAM. I came across a couple of strategies: one is running Firefox from RAM (as detailed in the Arch Wiki), which I know might increase RAM usage but would potentially boost speed. The other option is the profile-sync-daemon, but I'm not entirely sure how that works. I'm using Ubuntu 24.04 with the i3 window manager and believe I already have profile-sync installed. Which approach should I go with, or do you have other tips for optimizing Firefox?

If Firefox is struggling with slow page loads, it might be time for a CPU upgrade if that’s an option. Alternatively, consider visiting lighter websites that aren’t so resource-heavy. Sometimes, it’s more about what you’re browsing than the browser itself!
I get how frustrating it can be! Many users are switching to profile-sync-daemon for better management of Firefox profiles, which can help with speed. Just make sure to check out the documentation to set it up right since it can be a little tricky at first.
Honestly, I’ve noticed that Firefox can be hit or miss lately. It feels like it’s struggling more than it used to. But don't lose hope! There are still plenty of tweaks you can apply to make it faster. You can find some great custom settings online to enhance performance.
