Question

I have this code and this error in FireBug:

Error: Permission denied to access property \'toString\'

How can i fix this error?

Answer 1

That issue can be caused by an extension that isn't working properly.

Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
