You are saying the browser will not open in Safe Mode.

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there? Starting Any Computer In Safe Mode; Free Online Encyclopedia

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

Configure firewalls so that Firefox can access the Internet. {web link}

"safe mode with network support." I don't know what you mean by network support but I did start computer in safe mode and it did not help. I downloaded Firefox Nightly, then signed into mozilla account and retried to download firefox quantum ( I don't think I had firefox quantum before, just firefox). My computer did tell me I had updates today and I clicked "try tonight." After this issue, I looked for software updates and there weren't any, so I don't know if that is the issue. I cannot access my profile to import my bookmarks to firefox nightly and fire fox quantum still won't open, even after adding them to my list of "ok to open" in firewall and restarting computer. I really need firefox and my bookmarks.

Quantum is the current Firefox browser.

I downloaded Firefox Nightly

Did Nightly work properly?

Open Firefox Nightly. Then open your file browser to the bookmarks backup folder of your normal profile.

jscher2000 has a tool on his website to extract out your bookmarks and save them to an HTML-format bookmark export file. If you want to try it, here is the page:

To open the bookmarkbackups folder in Finder, use the "Open in Finder" button in the first table on the Troubleshooting Information page, and double-click into bookmarkbackups where you should see several dated files. From there you can drag and drop onto the conversion tool.

To import the HTML file, see the steps in this article: Import Bookmarks from an HTML file.

I was able to import my bookmarks to "Firefox nightly 2" but after the computer put itself to sleep, upon waking Firefox NIghtly 2 also does not open, the same as Firefox Quantum, even after restarting computer.
