Currently running Firefox 16.0.1 on OsX 10.7.5: Would like to know if there's a way to increase the number of Personas Firefox maintains? Looked @ about:config but couldn't see the line where to adjust integer. Thanks.

Firefox only stores data of a maximum number of personas (DEFAULT_MAX_USED_THEMES_COUNT=30)

  • resource:///modules/LightweightThemeManager.jsm

If you install more personas then Firefox will remove other personas to make room for the new persona, so it is best to keep a list or bookmark the site of your favorite personas.

You can override that maximum by creating an Integer pref with the name lightweightThemes.maxUsedThemes and set its value accordingly.
