Firefox 3 is not caching content

That what happened to me after the upgrade from Firefox 2 to Firefox 3. For some strange reason, cache was totally disable. To solve this problem you need to change 2 of your Firefox configuration settings:

1st Step

Open a new tab an type about:config

2sd Step

On the search bar that appears type browser.cache

3rd Step

Set the following atributes to true:

browser.cache.disk.enable and browser.cache.memory.enable

In my case, they were both set to false so in each browser request all the content was being downloaded… a little annoying.

i hope this helps

The cache is listed as one possible cause of 100% CPU usage. Disabling these properties is a workaround for that.

I didn’t know that ff3 was having CPU usage problems.

Maybe i’ll disable the memory cache and just use the disk cache. Because it’s very annoying to get all the content off the webpage in each request.

There is another parameter in there that allows or block SSL sites from being cached to disk. If FALSE (default) then it seems that memory fills up and future access to SSL sites will not be cached. Setting this to TRUE may be a security issue - but it fixed it for me.

I LOVE you! Thanks. I don’t know why it was doing this but all of a sudden my settings changed and nothing was caching. Erg!
