unicode ATL80.dll error message when trying to run firefox
Every time Firefox opened
Opera/9.80 (Windows NT 5.1; U; en) Presto/2.6.30 Version/10.60
Additional System Details
- User Agent: Opera/9.80 (Windows NT 5.1; U; en) Presto/2.6.30 Version/10.60
I had this problem as well. I found that somehow the firefox.exe file had been set to run in compatibility mode for Windows 95.
To check this on your system Browse to the firefox folder (C:\Program Files\Mozilla Firefox\) and right click on the file "firefox.exe".
Select "Properties" and then the "Compatibility" tab. Make sure the option "Run this program in compatibility mode for" is UNCHECKED.
Then try running Firefox as normal. Worked for me.
Best of Luck.
