3.0:

• Navigation bar now on top. I plan to add the ability to move it down like I did in version 2.0 but I don't want to delay this update any longer
• Bookmarks toolbar used now and putted above sidebar. Since it's quite short, it will be more convenient to use folders with short names and emoji instead of regular links
• Thin sidebar mode are removed. This mode was rather inconvenient and I didn't use it. Maybe I'll bring it back someday if someone asks for it
• All panels can be shown or hidden independently. Interestingly enough, I tried to implement it with various crutches for a long time, but nothing worked. It turned out that in userChrome Toggle settings it was possible to enable this functionality

2.0 version still available here

If you migrating from 2.0 you need delete fx-autoconfig.
To do it, at first clean up chrome folder, at second delete config.js and /defaults/prefs/config-prefs.js from Firefox installation folder.

If you new user, skip it.

If you migrating from 3.4 you need delete Sidebery styles from its settings.
To do it go to the Sidebery settings > Styles editor

Before | After

If you new user, skip it.
