Basically this works in such a way that a cache mismatch that you save in your system and in the data of the site can cause the problem that a web page is slowing down your browser in Firefox.

In her you will have to go to Cookies and Site Data and click as is obvious on the option that says delete data. Don't forget to check the cache and cookies boxes before, remember. Then you just have to open and close Mozilla Firefox again and navigate without problem to see if the error appears again.

If you have a 32-bit computer you may have this option, if you are 64-bit, don't bother looking for it since it is not present on those types of Windows systems. Basically this is a protection designed by Adobe that serves as a bit of a firewall against malware or viruses, but Mozilla Firefox's own engineers have warned that it can cause some instability in the browser and therefore they recommend disabling it if it gives errors.
