Can Firefox 64-bit be updated to support "browser.cache.disk.capacity" over 4 GB?

Postáilte

Hi,

It looks like that despite being 64-bit "browser.cache.disk.capacity" is still limited to 4 GB. So I was wondering if it will be possible to update 64-bit version to support cache size over 4 GB?

It is possible to set / modify the value of "browser.cache.disk.capacity" in "about:config" to be over 4,194,303, but it won't work, as browser will stop caching altogether.

Thanks

4GB cache is about 1 mega of cache entries for most users. The index is going high and performance is decreasing quickly.

I don't think they would decide to increase this limit at this moment, even for 64-bit systems.

This setting has nothing to do with 32bit or 64bit. It has to do with the disk space Firefox uses to store your browser's cache (instead of re-downloading websites you visit frequently, it stores a copy locally). I'm not sure why you think this would be different with 64bit.

The only thing I noticed that while it is possible to modify setting to value over 4 GB (see screenshot) it actually won't work. But for 64-bit version user should be allowed to increase it as systems nowadays have larger RAM and SSD storage, so performance won't be an issue.

That pref has nothing to do with RAM, it is a file stored on your hard drive. Increasing it too large can slow Firefox down, which is why there is a limit.

I am positive it is 4 GB, as I tested it with latest version 60.

I'm wondering both why you want to raise the limit, and why you think 64bit makes a difference?

Because sometimes it is very convenient when traveling to browse websites that rarely change, for example docs, and large cache allows to do that.
