Waterfox works in Windows, no issues with extensions and supposed to have a greater compatibility with legacy extensions.

Fennec works in Android, no issues with extensions and has the third party trackers removed.

If the developer and nightly versions of Firefox 9which are supposed to work properly) make you uncomfortable there are firefox versions that can deliver the same usability and are not affected by this bug.

If you use Android, you can get Fennec from the F-Droid online store.

If you use Windows, you can get Waterfox here: https://www.waterfox.net/

Fennec is just a fork of Firefox with telemetry disabled by default and known third party trackers removed.

Waterfox is a fork of Firefox that tries to be more geared toward users who want more control, its main differences are telemetry is disabled by default and it is supposed to support more extensions but I have not tested this out.

What's there to trust in Chrome? Google not only gets to see everything you are doing that interests them in the browser but also refuses to allow full functionality and/or use of various extensions (depending on the extension) that are available in firefox. Besides, would you trust a browser by a corporation who tries to hinder those who seek to take control over their mobile devices, try to get spyware into everything and has their search engine programmed to allow them to decide what information you have access to on an individual basis to only let you know what they feel you should know?

In Android I would suggest using Fennec (which can be downloaded using F-Droid). On my android phone this uh, bug? does not seem to affect anything and Mozilla's telemetry is disabled by default. Granted, you can disable it manually in any firefox browser by typing telemetry in the search box in about:config and setting the values you do not feel comfortable with there to false.
