Which versions of Firefox do you offer support for (i.e. security patches etc)?

Hello,

I would like to know:

1) the last 5 versions of Firefox for each OS. 2) which versions of Firefox, Mozilla officially offers support for. Does Mozilla offer support only for the latest ? With support I mean security patches etc.

Thanks in advance.

What do you mean? What type of support?

As to updates, only the current versions receive updates. Not older versions.

If you have a question on recent versions, just ask away. Questions on very old versions might not be helpful.

Hi aspa.strouvali, the current releases are supported until they are replaced with new releases. Support for old releases ceases when a new release is available. Make sure to upgrade promptly.

For desktop:

For Android, use the Google Play app to install/update

For iOS, use the AppStore app to install/update
