I’ve never intentionally changed any settings about browser protection, yet I have for months this problem:
After windows is loaded (v7 64bit) I can’t use Firefox for some time (about minute or two). Browser loads, but with default settings. It happens because something locks prefs.js file - Firefox generates new file with default settings and uses it. I have to:
- wait some time
- close browser,
- goto my profile folder, delete prefs.js
- rename invalidprefs.js to prefs.js
- start browser again, restore tabs from backup
Which is overall annoying.
Before that time file prefs.js is locked by unknown process (not identified by handler64 identifier from Sysinternals).
How can I fix this ?
