Browser Support • Re: Why is Pale Moon so slow?

Speedometer says PM's pretty slow, along with my experience with real-life web apps. It's not for the impatient, but in my case, it just happens to work a bit better than other browsers due to their inflexibility in places I take for granted. Although performance of Pale Moon is still often aggravating.

And it can be additionally slowed down with extensions and UI styling.

In my case, startup takes 14 seconds! While empty non-customized profile takes 3. That's 11 second difference, which is not insignificant. Recent (customized as much as still possible) Firefox on the other hand takes 5. These results are when browser files are already cached in RAM. Firefox takes about 24 if files are yet to be loaded from disk.
