Firefox WILL NOT OPEN at all--even in Safe Mode--and even after a clean reinstall. Goes directly to Mozilla Crash Reporter. Chrome and Safari working fine. Mac desktop, running 10.12.6

This could be a problem with the fbplugin (Facebook photo uploader) in the "Internet Plug-Ins" folder.

What's your computer system and Firefox version?


If you can't get Firefox to open, you will have to do this the hard way.

https://support.mozilla.org/en-US/kb/mozillacrashreporter Open the file browser / explorer on your computer. Note: You may have to enable Show Hidden Folders / Files. Enter this in the address bar;

Windows: %APPDATA%\Mozilla\Firefox\Crash Reports\submitted Win 7/Vista: C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Crash Reports\submitted Win XP/2000: C:\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Crash Reports\submitted

Mac OS: /Users/<username>/Library/Application Support/Firefox/Crash Reports/submitted Linux: /home/<username>/.mozilla/firefox/Crash Reports/submitted

The crash report is several pages of data. We need the report numbers to see the whole report.

Copy the most recent 5-7 File Names in the folder. Post the information in the reply box.

Computer os mentioned in original post. I just downloaded the most recent Mac version. Will check specs on that later.

I'll likely just scrap Firefox and move to Chrome. Not much reason to hassle with it.

Were you able to get the crash report ID's requested above?

No--that path doesn't lead me anywhere. I don't have a "Firefox" folder in my Application Support folder. I do have a "Crash Reporter" folder but there's nothing recent there. All I have otherwise is this, from the Mozilla Crash Reporter:
