Hello,

is this only me or do others have this effect, too: If I check
"Disable HTTP Cache" on devtools settings I'd expect that the page I
work on is not cached (loaded from source file any time I reload).

However, if I change something on the page (in my case some javascript)
with an external editor and reload it, it is not updated in the browser
and in devtools. It doesn't matter whether I press F5 or Ctrl+F5.

If I uncheck "Disable HTTP Cache" the page is updated properly, if I
press Ctrl+F5.

Tested both in FF53 and FF54 developer edition.

I normally keep "Disable HTTP Cache" checked. As it happens I just yesterday unchecked it (that is, I enabled the cache) because I was working on a JS 'preload components' function and I needed to see whether the items were caching properly or not. (I'm running Mac FF 53.0.2).

The devtools checkbox setting seemed to work correctly; my page loaded correctly whether or not I had the cache enabled; and my function affecting what gets cached worked correctly too. Lots of things in the devtools seem broken to me, but that's not one of them. So I'm guessing it's something in your setup. You use the phrase "loaded from source file"... are you loading HTML files directly from your file system, or are you using a development server? Perhaps that might affect how the cache works? (I'm using a local Apache dev server.)

BTW... I think I read somewhere that the cache checkbox in the devtools only has an effect if the devtools are open; i.e. that setting is not "persistent" once you close the devtools window. However I haven't tested this.

Hello,

I use a local server as well.

The option label says that it only works for tabs with opened tool box.
First I closed and opened the devtools to get the page to load properly
until I tried to uncheck "Disable HTTP Cache"...

If your page is in an iframe the file may be reloaded but the JS tab in devtools does get updated.

This has been the case since the JS2 update and affected firebug too.

That should have read : but the JS tab in devtools does NOT get updated.
