Hi I am facing a very strange problem. I cannot open the "about: config" page. The page comes out empty (img.1) Tried different search engines, different modes and security settings, nothing. Also, the viewing function in PC mode does not help. Please tell me what to do? I searched a lot for information on the net, but did not find a single site that would talk about such a problem There is also a question about "Secret Settings" that opens in the settings, the "About Firefox" tab, but the tab is empty. Maybe there is an opportunity to make the tab work? P.S. To activate the "Secret Settings" tab, you need to repeatedly click on the Firefox icon in the "About Firefox" tab (Fig. 2), the browser will notify you that the "debug menu is enabled". After that, two additional tabs will appear in the settings menu (Fig. 3). All add-ons were disabled in the "about: config" page and the page was added to the browser security "exceptions". Thank you in advance for your cooperation))
