Check and tell if its working.

The above reply has done nothing for me to resolve the major issue of FireFox 6 running so slow.

My Box Dual 3.8 Xeon Processors 16 Gig Ram Windows 7 64 bit.

No antivirus

FireFox setup is Remember No History Running default theme I have maybe 6 plugins all of wich are up to date Network Cache is always cleared

The above poster is merely working on getting his post count up or something because he has responded to every thread with a firefox 6 issue being slow with the above answer.

Would someone from support chim in because this has become a major issue.

Thank you very much.

@tobynt,

mha007 has posted the reply for the website not being displayed correctly first time. It has nothing to do with Firefox 6 is slow.

Clearing the network cache fixed the problem for me (I did not think it would be that easy).

Running Firefox 8 on 64-bit Windows 7 Home Premium.

I still do not understand why everyday I use firefox my cache is all cleared.

• Make sure you are using the "Remember History" setting as described in this article -> Settings for privacy, browsing history and do-not-track

• IF you use "Clear Recent History" feature, DO NOT select "Cache" as described in this article -> Delete browsing, search and download history on Firefox

• IF you use Privacy Cleanup softwares like CCleaner, DON'T SELECT FIREFOX IN ITS SETTINGS. These softwares can be responsible for Deleting your Firefox Settings.

Check and tell if its working.

Make sure that you do not use "Clear history when Firefox closes" to clear the "Browsing History".
