Is your Firefox slow like mine? Make it work really fast very easily!!

From the past few days I have begun to find Firefox to become slower and slower by the day. First I thought I must blame the latest 3.5.3 version for Firefox being slow. Even it took a whole lot of time to start-up and that's when something irked me to research further on what was happening.

I could make out that there was a lot of Read (I/O) operation happening when Firefox starts and also the RAM took a big hit. So I could narrow it down to be some faulty add-on that must have been playing the trick. So, I went ahead and opened the options and began hacking a few settings.

Opened the Tools > Options > Privacy. Change the drop down to "Use Custom Settings for History" and then you will find the culprit sitting quietly over there. There is a default setting in Firefox to remember history for 90 days which is really huge. This basically means that Firefox will be remembering each and every site you have been visited with the details such as date and time of the visit for the last three months that you have been using Firefox!!!. This will be really very very huge if you are a power user like me who spends considerable time online.

Well, to fix the slowness of your Firefox is to
simply goto the Privacy tab (Tools > Options > Privacy) and changing the drop down to "Use Custom Settings for History" and then change the setting to a much smaller value say 5 days!!
Then head over to Tools >> Clear recent history and select "Everything" in the drop down and hit Ok. Once that is done - close and open Firefox to see so much of speed!!

Hope this tip helped you in making Firefox work much faster.

    Nice one Jason. I would also add that we should the option of "Automatic Updates for AddOns" since that would always take time[while starting up as well as while browsing since it would keep on checking the updates for XXX interval of time]

    Very helpful indeed, I was wondering why my firefox had been slowing down since the last update. Now it's much faster and doesn't lock up between tabs either.

    Thank you very much Jason!
