Forum zhromadźenstwa Firefox

Hi, I have a brand new macbook air and wanted to install my preferred browser, Firefox, but after installation Firefox will not launch. I’ve tried to install version 133.0.3 and when I try to launch it, Firefox always freezes and show 'Firefox (not responding)'. I have restarted my mac, reinstalled Sequoia OS, uninstalled/redownloaded/reinstalled, and I cannot get Firefox to launch, ever. Safari (built in) and DuckDuckGo (new install) browser both work.

Please let me know what I can try to do to get Firefox working.

This issue is about two executables in C:\Program Files\Mozilla Firefox:

• firefox.exe, which starts Firefox, and
• private_browsing.exe, which starts Firefox in Private Browsing mode.

If you start firefox.exe while private_browsing.exe is running, it restores the last session. I have been experiencing this issue for about a year.

Steps to reproduce:

• Start firefox.exe.
• Open x.com instead of your home page, and xe.com on a second tab.
• Exit Firefox (Alt+F4).
• Start private_browsing.exe.
• Start firefox.exe.
• Actual result: Three tabs are opened: x.com, xe.com, and your home page.
• Expected result: only your home page is opened.

Can anybody confirm the bug? Will there be a fix for this?

Every so often for the past few days this "unfinished" program window has appeared on my pc on top of a normal Firefox window (see attached png). Does this have something to do with Firefox? I think the same thing appears when I first open Firefox, then it gets "filled in" and appears as a normal Firefox window. I am running Firefox 133.0.3 (64-bit) on Windows 10 Pro Version 22H2 build 19045.5247 Windows Feature Experience Pack 1000.19060.1000.0.
