Hi there! I see you're experiencing tab crashes in Firefox 151.01-2 on openSUSE Tumbleweed when clicking the 'home' button or DuckDuckGo shortcut, specifically loading the DuckDuckGo homepage. That sounds troublesome. Let me get a clearer picture first:

- Does the crash happen immediately when you click the home button or shortcut, or does the page start loading first?
- Is this issue only with the DuckDuckGo homepage, or any homepage you set?
- Have you tried resetting or changing Firefox’s homepage to something else to see if it still crashes?
- Do you use any extensions or add-ons that modify the new tab or homepage behavior?
- Does the DuckDuckGo VPN app also crash when this happens, or is that a separate issue?

These will help me narrow down the cause. Meanwhile, a few straightforward steps we can try:

1. Clear Firefox Cache & Cookies: Sometimes corrupted cache can cause loading crashes. You can do this from Settings > Privacy & Security > Cookies and Site Data > Clear Data.

2. Test in Firefox Safe Mode: This disables all add-ons. Restart Firefox with add-ons disabled by clicking the menu (☰) > Help > Restart with Add-ons Disabled… Then try clicking the home button again.

3. Check for Firefox Updates: Though you mentioned version 151.01-2, ensure your system and Firefox packages are fully up to date from openSUSE Tumbleweed repositories.

4. Try a Different Homepage Temporarily: Set Firefox’s homepage to something simple like https://example.com and see if clicking home still crashes. This isolates if the crash is related specifically to DuckDuckGo homepage.

If these don't fix it, let me know what you observe based on the above questions, and we can dive into more technical diagnostics like Firefox crash reports and looking into potential conflicts with system libraries, VPN app integration, or underlying rendering engine issues documented on openSUSE forums.

Looking forward to your reply to help get this sorted for you!
