Clicking "Allow" on the permission dropdown will allow flash until the browser is shut down in Firefox 70 and later.

Note that Flash Protected Mode is different than "Ask to Activate" and "Always Activate" (the latter is no longer possible).

There are ways of allowing Flash to remain activated, but it's highly discouraged due to the enormous number of security flaws Flash suffers from (other browsers such as Chrome have disabled it by default now as well).

To do so:

1. enter "about:config" into your address bar (without quotes) and hit enter
2. read/accept the warning
3. in the search bar type "plugin.state.flash" (no quotes)
4. it'll be be set to "1". click on the pencil icon and replace the 1 with a 2, then click the check mark to save
5. restart Firefox to enable the changes

Note: I have not personally tried this but from what I've read, you may still be prompted for each new site you visit that uses Flash but will just need to enable it that one time for each site.

You can use the policies.json file to allow Flash.
