Hello Everyone, Since the last week, my Firefox is continue crashing with most of pages I visite. I tried the following: 1- Update Flash player plugin to the last version. 2- Uninstall and reinstall Firefox. 3- Uninstall, delete data at %appdata%, install again. 4- Install Firefox extended support version. Nothing works. Checking the crash log I noticed the issue is related to the following signature: Signature GlyphDataElement<T>::TryGetExistingGlyph Which reports this Crash Reason EXCEPTION_IN_PAGE_ERROR_READ / STATUS_DEVICE_DATA_ERROR Not sure how to proceed at this point. Please advice. Thanks, Denis
