Firefox's Web Opening Time is slow.png

The results are measured by DIVA, and firefox is always inferior to chrome, although there may be differences depending on the network.

espn opening Time(Chrome VS FF)
With those sorts of test need to startup Gecko each time. As I understand Android keeps parts of Blink in memory thus does not need to pay the startup costs each time.

The page opening time is slower than Chrome as below sites.

Starting in Firefox 51 we extract libraries to the cache directory on the first one. By clearing the data before each run, this step is repeated every time, which is not what would happen with normal usage. I recommend starting Firefox once without loading a page after clearing the data, then repeating the rest of your test.
You can use the 'Clear private data' button in the Firefox settings to clear the cache, if that's what you're trying to do.
