It’s not absurd at all. They know the IPs, they know those devices use the same network, and they also know where they are located pretty accurately: the Google Street View cars also scan for WiFi networks and map them to their location.

2 devices consistently connected to the same router, to the same network, in the same place… must belong to the same person or to 2 people sharing a home. If cookies set by other websites and seen by Google show similar browsing habits, it’s probably the same person.

You just mentioned 2 different Google accounts: if your devices are connected to Google accounts they are already getting a lot of information from you that way, and Google knows that those 2 accounts are related.

I’m not sure that’s a great idea. I understand wanting to avoid the hassle of reinstalling Mull and having to go through all the Settings again (I just did that a couple of days ago), so if you want to keep your current F-Droid Mull install I’d recommend installing another updated flavour of Firefox, like Fennec or Iceraven, using FFUpdater (https://f-droid.org/packages/de.marmaro.krt.ffupdater/) and using that one until the updated Mull is pushed to the F-Droid official repository.

Yes, there are efforts to build these two and more apps affected by the issue preventing updates to be built

The issue preventing updates should be resolved soon thanks to @linsui fixing it!

You’re probably getting your Mull updates via the DivestOS repository, not the official F-Droid repository.

You can download an updated version of Mull with the security vulnerability fixed, from the DivestOS F-Droid repository: https://divestos.org/fdroid/official/. If you currently have the F-Droid version of Mull installed you will need to uninstall it first.

There was a critical vulnerability found on Firefox some days ago: CVE-2024-9680. Fennec and Mull are forks of Firefox. They both fixed this issue already in their source code, BUT there is a problem preventing F-Droid from building these updated, fixed versions.

In the case of Mull, you can download the updated version from the DivestOS F-Droid repository: https://divestos.org/fdroid/official/, but if you are currently using the F-Droid version you will need to uninstall it first, since they have different signatures.

Google is not killing uBlock Origin, it is making its Chrome browser even less user friendly. Just use Firefox or a Firefox fork.
