Add a gecko ID to the extension

[TheFrenchGhosty]

Some browsers (like GNU Icecat) will mark an add-on as corrupt if the manifest.json doesn't contain a gecko ID.

This PR fixes that.

I just noticed that a gecko ID is included in the firefox_manifest-extra.json but sadly it isn't working that way and it really needs to be in the manifest.json

Doesn't the addons store add it automatically? It doesn't work in chrome if added (that's why it is not there)

[TheFrenchGhosty]

Sadly no it needs to be added manually into the file... I guess the solution is to do 2 different manifest.json, one for each browser.

Are you downloading it from the addons store or from the repo?

[TheFrenchGhosty]

I tried both, the problem is here for both.

See this gif for the store:

This applies to Firefox versions <= 48: https://stackoverflow.com/a/56823677/1985387.

I have a fear that adding it back will result in Firefox Sync issues.
