I am experiencing a Firefox crash when I tried to upload images to WordPress using the built-in WordPress Flash image uploader. In Google Chrome it works fine but Firefox crashes immediately when i try to upload an image.
The issue seems to be caused by the Google Gears extension for Firefox, I am using Google Gears to speed up WordPress on the local machine. If I disable the Google Gears extension the wordpress image uploader works fine. Strangely the problem occurred yesterday for the first time and it is continuing, i donâ€™t remember updating Google Gears addon for Firefox or Firefox itself.
There is an option in Google Gears settings to selectively disable a single site or more, i tried this option also but it is not a solution as Firefox is still crashing. The only option now is to completely disable Google Gears or just use another browser like Google Chrome or Opera.
