Diễn đàn hỗ trợ Firefox

I have two identical computers running Firefox on Windows 7. No serious issues for 3 years or longer.

Just recently, version 100 showed "Unknown Source" instead of the normal UAC authorization window which lists mozilla.org as the source.

The 100.0.1 update showed the same warning.

This only occurred on one of the computers. The other one does not show the warning.

Firefox worked fine after doing the downloads anyway, but the "Unknown Source" is not right and makes the user think security is being compromised.

Find the "switch" that gets "activated" (when using ANY private browser window) that prevents us from using "printscreen" AND...ALL other "printsreen apps" as well (such as "windows snipping tool"). After using ANY private browser, Printscreen just shows an all black screen! Once you've used a private browser window (on a Win 7 desktop)...you no longer have any printscreen ability until after you power-cycle...when it's too late!! Printscreen ALWAYS shows an all black screen!

Try it for yourself on YOUR desktop...regardless of your system!

AARRGGHH!! >:-(
