Firefox Community Forum

When I open Firefox it opens a maximized window with tabs, then it opens a minimized with a single tab, then it reopens a maximized window with all session tabs. Each window displays in succession, one window at a time.

I'm on desktop using Windows 11.

I just read a post saying this behavior was caused by the resist fingerprinting feature. Can someone explain how that causes the repeated opening of browser window 3 times. Is there a way to retain the anti-fingerprinting behavior w/o the multiple window opening behavior?

Since I updated my MacBook to macOS Sequoia, I have no access to local network pages (except 127.0.0.1, localhost and 192.168.0.1) - an "Unable to connect" error appears. Immediately after the first launch of Firefox, a request for local network permissions appeared, which I accepted, but it didn't help. I performed all the actions from this article, and also used the terminal command reset All approval status for org.mozilla.firefox and Firefox disappeared from the privacy settings. While a request for access to the microphone and camera reappeared after restarting the browser, no question about the local network appeared. The problem only occurs in Firefox (version 128.5.2esr) and does not appear in other browsers (checked in: Firefox Developer Edition, Firefox Nightly, Safari and Google Chrome). macOS 15.1.1 (24B91).
