One problem that arose because of this switch was an increasing Firefox profile folder size as there was no build in way to optimize the SQlite databases regularly. We reviewed a solution to this problem a while ago (read: optimize sqlite databases in Firefox) which involved running a batch file in the Firefox profile directory to optimize the databases and reduce their file sizes. The process can be best described as a defragmentation to close gaps that contain no data which will free the disk space.

The Firefox add-on Vacuum Places makes this process more comfortable by providing the means to run the database optimization right from within Firefox. The experimental add-on will optimize the SQLite databases of the active Firefox profile whenever its button in the Firefox status bar is pressed.

The database size reduction depends largely on the amount of data in the database, the time it has been in use and the last cleanup. A run on a test system (using the batch file) reduced the size of the profile folder from 64.8 Megabytes to 53.4 Megabytes.

Vacuum Places can be downloaded from the official Mozilla Firefox website. It is advised to create a backup of the Firefox profile folder before running it for the first time.
