Word about a new caching back-end for the Firefox web browser first spread when the lead designer of the project revealed that Mozilla was working on it in an attempt to protect the cache from crashes or kills of the Firefox process, and also to eliminate any caching related hangs.
The new caching back-end launched today in the latest Nightly version of the Firefox web browser.
It is interesting to note that it landed in desktop and mobile Nightly versions of the browser, and that it is turned off by default.
Interested Firefox users, and who would not be considering that they run the most cutting edge version of the web browser, can enable the new http cache of Firefox in the following way:
Note that you need the latest Firefox Nightly version for this. Make sure it is up to date if you do not get the preference listed here.
The preference has two values: 0 means it is disabled and the old caching back-end is used, and 1 means it is enabled so that the new cache is used by the browser.
Before you restart the browser, you may want to hear about other new preferences that have been added to Firefox in the wake of this.
The lead developer notes that the system has some bugs currently. The disk cache is for instance not automatically cleared of old files if it is about to exceed its default limit. This needs to be done manually for the time being, but will be handled by Firefox automatically in the near future once the bug has been fixed.
Mozilla plans to enable the new HTTP Cache in the fourth quarter of 2013. It will still take several release cycles before it lands in the stable version of Firefox.
Most Firefox users should benefit from the new caching back-end performance-wise, or do not notice much of a difference if they work on a fast system (e.g. with a current generation Solid State Drive).
Performance is just one aspect however, and most users will certainly appreciate the fixing of cache related hangs and caching related issues when the browser crashes or is terminated in another way.
