I have listed some information below that may help with the issue you are having with your browser.
Complete a soft reset on your device. To complete a soft reset do the following below:
-Remove the battery on your device (the power does not need to be off)
-Leave the battery out for a few seconds (ex. 5secs)
-Place the battery back in and wait for the full reboot.
Try your browser once again.
***If it does not work I have listed a Blackberry Knowledge Base Article KB21377 below on this exact error message.
I hope this information was helpful.
