I still get a script error even tho I have tried all the solutions and It's on more than one site, plus firefox is running very slow?

I started having this problem just yesterday. I tried reinstalling firefox, and all the solutions listed, none worked and it's also running very slow. Help!

Paste the error message or a screen shot of it please.

What do you mean by running slow ? When does this happen is it only on certain sites ?

Have you tried speedtests on your internet connection,could that be part of the problem ?

You have Windows so will have Internet Explorer installed I imagine, how does that compare ?

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

See:


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

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.
