Firefox Support Forum

I'm on the Sony Vaio, using Mozilla Firefox but I keep getting this error on the majority of websites.

Where is this coming from and how can I fix it?

Any help would be gratefully received.

I also have Bit Defender (in case this has anything to do with it).

Running OS 10.13.3 and had the latest version of Firefox running as my default browser, auto-updating. on 3.11.2018, I started getting the missing profile error. I followed several support threads with this issue, like https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing-inaccessible. I could not find or repair the profile.ini file or even find a Firefox folder in ~/Library/Application Support or ~/Library/caches. I had a Mozilla folder in the former but not Firefox. I also had Firefox synced to my Firefox Android browser.

I've reinstalled 58.0.2 a few times, nothing helps. I cannot find profiles.ini anywhere on my computer.

I've tried including the Troubleshooting information, but it doesn't work, I assume because I'm on Chrome?

Thanks for any assistance you can provide.

I am on a macbook pro. I have deleted app and at, reinstalled, still get this error:Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I rename the Firefox folder /Library/Application Support/Firefox and still I get this error: Your Firefox profile cannot be loaded. It may be missing or inaccessible.

In terminal I tried ot create a new profile using: /Applications/Firefox.app/Contents/MacOS/firefox-bin -P but receive this error in terminal: Error: Access was denied while trying to open files in your profile directory and this error pops up in Freifox: Your Firefox profile cannot be loaded. It may be missing or inaccessible.

First off, thanks to everyone who pitches in to help resolve this headache. Sheesh!

Problem: The Header image and text do not display properly in Firefox: The content does displays properly in Chrome, Opera and Safari. By the way: I have read and attempted all the applicable troubleshooting suggestions Firefox has supplied without success.

Website: www.twoworlds.ca The page in question is www.twoworlds.ca/other-world.html

Note: I coded the site myself using largely a w3.css framework. Admittedly, the source code is messy. I'm still chimpin' around (experimenting) with things.

Incredibly, am unable to upload two 137 kb screen captures of the problem for visual reference - an endless spin wheel for 12-minutes. Wha..? In that case, please visit my site in Chrome and then Firefox to see the difference. the site again: www.twoworlds.ca/other-world.html

Thanks.

I've tried deleting the firefox profile folders and launching the application. Still get the same error message. I tried deleting all firefox files, restarted and reinstalled and still get the same error message. I had Sophos Home installed and removed that and it still did not fix the problem. Also when i try to launch the profile manager via terminal it still just gives me the profile error message. This is extremely annoying.
