So I just have Firefox portable with all my bookmarks and all my Add-Ons.īut each time I start Firefox portable, there is 'Setup Sync' in the Firefox menu (the orange Firefox button) instead of Sync now. I also uninstalled Firefox on my work PC. Then I opened Firefox 9.0.1 portable, set up Sync (selected that I have lost the other device and Firefox generated a new Sync key for me).Īfter that all bookmarks are downloaded to the portable version. Here I suddenly had Firefox in English language (instead of German language) but I downloaded Firefox 9.0.1 portable again (from the web site) and installed it manually (see ).Īfter setting up all Add-Ons in the portable version, I opened Firefox 8 (non portable), synced all bookmarks and uninstalled Firefox 8 (I selected to remove all settings). Then I downloaded Firefox 8.0.1 portable and set up some Add-Ons (not the Sync, I was still testing the portable version).Īfter some time Firefox portable was updated by the PAP to 9.0 and some days later to 9.0.1. There I set up Firefox sync to sync my bookmarks between my private PC, my work PC and my Android phone. I had Firefox 8 installed version (not the portable version). In the Firefox menu (the orange Firefox button) there is 'Setup Sync' instead of 'Sync now'.

If I set up sync to an existing account and restart Firefox, then all sync settings are gone. I recognized that Firefox Sync is not working.

Firefox sync encountered an error
