Resetting FF didn't solve toolbar icon removal upon restart. Any ideas?

After setting up my toolbar with the new toolbar menu, it keeps removing most icons upon restart. Not even to the menu, but removing them completely to the big bin of unused features to the left of the menu in Customize mode. I reset Firefox per the support page suggestion, but this hasn't had any effect. Oddly, I haven't had this problem after updating to version 30 on my laptop, only on my desktop. Any suggestions? I'm on a Mac Pro running Mavericks.

الحل المُختار

Current Firefox releases store the toolbar customization in the browser.uiCustomization.state pref. You can inspect and modify prefs about:config page.


You can check for problems with preferences.

Delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.

It worked — thank you! While it's a pain to reset all my preferences, it's worth it to get back my custom toolbar. Almost was thinking I'd have to move to Chrome.

Didn't it work to only reset the browser.uiCustomization.state pref and possibly delete the localstore.rdf file?
