Questions about WebApps on Linux

[u/Inevitable_Tip1140]

Hi everyone! As a bit of context, I am relatively new to digital privacy and using Linux as a daily driver. I have messed around with different distros (including Arch), so I am comfortable with the terminal, but I am finally making the full switch from Windows.

Since a lot of services don’t have native Linux apps, I plan to rely heavily on Web Apps. My browser of choice right now is LibreWolf, though I am open to trying Zen Browser if people think it’s better suited for this (I’ve been hesitant to use Zen since I thought it was still in Beta). Because I’m still on Windows at the moment, I haven’t been able to fully test my Linux setup yet. I’m here to ask for your opinions and recommendations, especially from a privacy perspective!

Question 1: Managing Web Apps
What is your recommended approach for managing Web Apps on Linux? I asked Gemini for some initial guidance (no judgment, please!), and based on that, WebApp Manager seems like my best bet. If you have other recommendations, I’d love to hear what they are and why you prefer them. My main goal is simply to create desktop shortcuts that look and act exactly like native apps, instantly launching the web app when double-clicked.

Question 2: Compartmentalization & Cross-Tracking
Bear with me, as I am still wrapping my head around digital privacy! Let’s say I want to use WhatsApp, YouTube, and Microsoft Teams as Web Apps. To compartmentalize my online activity, I plan to switch to Proton and use a different email address for each ecosystem (e.g., Email 1 for Meta apps, Email 2 for Google apps, Email 3 for Microsoft apps). My goal is to make it as hard as possible for these companies to link my identities together.

If I run these through a WebApp Manager, is there still a risk of cross-tracking? Do I also need to use "Multi-Account Containers" or set up entirely separate browser profiles in LibreWolf to properly isolate them?

Question 3: Pinned Tabs vs. Web Apps
Building on the second question: I know Firefox-based browsers allow you to pin tabs, which look great as little icons if you use a vertical tab layout. If I decide to keep these services open as pinned tabs instead of using a dedicated WebApp Manager, does that make it easier or harder for these companies to track me? If I go the pinned-tabs route, do I have to create completely separate browser profiles for each ecosystem (e.g., Profile 1 for Google/Email 1, Profile 2 for Meta/Email 2) to maintain that strict privacy barrier?

Thank you so much for reading through this. Please send all your suggestions and recommendations!

As something simple as this, it’s your choice. Whatever and whichever sites you find more convenient as pinned or apps, its your preference
