Support Hunspell spellchecker dictionaries in Android

[ssvb]

Is your feature request related to a problem? Please describe.

Spellchecking support is also necessary in Android. Normally this task is delegated to a virtual on-screen keyboard in Android, which does spellchecking as you type. So the Firefox developers made a decision to disable Hunspell in their Android build, wrongly assuming that none of the users will miss it there. However this is not good enough for at least two use cases:

• using an external bluetooth keyboard with an Android tablet instead of the virtual on-screen keyboard.
• spellchecking is sometimes desired for a full page of already existing text (e.g. when editing a Wikipedia page) rather than merely spellchecking the newly entered text as you type.

The desktop version of Firefox still supports Hunspell.

Describe the solution you'd like

Enable the Hunspell engine in the Android build of Waterfox and allow installing Hunspell dictionaries.

Describe alternatives you've considered

• LanguageTool browser extension - does the spellchecking job, but it sends the typed text to a remote server on the Internet (essentially works as a keylogger spyware).
• Harper browser extension - does the spellchecking job, but it's too heavyweight (high memory usage in about:processes) and, more importantly, only supports English.
