adb and fastboot must know

Install android SDK (bottom of the page) or full android studio if you need to develop on android.

fastboot looks like adb but it is used when device is in bootloader (or fastboot).

Check connected devices

adb:

stephendonner

driver = webdriver.Firefox()
driver.get('https://pypi.org')
with driver.context('chrome'):
    driver.find_element_by_css_selector('image#pageActionButton').click()
    driver.find_element_by_css_selector('#pageAction-panel-screenshots').click()
    with driver.context(driver.CONTEXT_CONTENT):
        sleep(2)
        onboarding = driver.find_element_by_id('firefox-screenshots-onboarding-iframe')
        driver.switch_to.frame(onboarding)
        driver.find_element_by_id('skip').click()

Preferences

All preferences for the DNS-over-HTTPS functionality in Firefox are located under the "network.trr" prefix (TRR == Trusted Recursive Resolver). The support for these landed in Firefox 60 but will be polished further in 61.

network.trr.mode

set which resolver mode you want.

0 - Off (default). use standard native resolving only (don't use TRR at all)

1 - Race native against TRR. Do them both in parallel and go with the one that returns a result first.

Preferences

All preferences for the DNS-over-HTTPS (DoH) functionality in Firefox are located under the "network.trr" prefix (TRR == Trusted Recursive Resolver). The support for these landed in Firefox 60 and has been improved in Firefox 61. Goto about:config to set these preferences.

Some users have reported needing to restart to have the changes take effect. The DNS tab of the about:networking page will indicate whether a name was resolved via TRR or not.

network.trr.mode

set this preference to 2 to enable DoH in a mode where DoH is used as the first choice for DNS, but it will still fallback to native DNS for full backwards compatibility. Set to 0 to disable DoH.
