Hi! I'm experiencing a strange issue with Firefox. Every time I start Firefox, the site addons.mozilla.org opens automatically — and it opens in fullscreen mode (as if I pressed F11). Here's what I've tried so far: I disabled all extensions, but the problem still persists. I changed the homepage settings to a blank page and even other websites, but it doesn't help — addons.mozilla.org still opens. The issue happens even after restarting the computer. I haven't reinstalled Firefox yet — I’d like to understand what might be causing this first. Any help or suggestions would be appreciated!
