Cannot restore extensions with Fx v42?

[cbaker_admin]

It would appear that Fx 42 has broken the ability for FEBE to restore extensions. I am working on a fix. In the meantime, you can still restore extensions by using Tools > Add-ons > (gear icon) > Install Add-on From File...

For the time being, themes can still be restored with FEBE > Restore > Restore Themes., but this may break also.

Hi Chuck

Don't know if this is related but I am also having trouble getting FEBE to work with Tor Browser and the Tails CD. I am using FEBE 8.8.1.

I got in touch with them (the Tails people) and they said to ask you about it. I seems that recent changes made to Tor Browser could be the problem but they would not elaborate.

For windows (XP Pro Sp3) I am using Tor Browser version 5.0.6 (based on Mozilla Firefox 38.5.0). It just hangs forever when trying to do a backup and I cancel the operation.

For Tails I am about to download the new version 1.8.1 and will burn it to a DVD and see if has made any difference, if not I will let you know.

What specific problems are you encountering? Are you getting any FEBE related messages in the error console (CTRL-SHIFT-J, type febe in the 'Filter output' field in the upper right of the console window, copy/paste in your response)?

I don't have a Tail CD, nor the Tor Browser installed, so I cannot test it myself.

Sorry about the delay. The main problem (XP) is that Febe will not perform a backup - it just stalls. Here is the error log:

On Tails 1.7 it gave this message (not tried 1.8.1 yet):

"An error occured reading the permissions table. no such table:
moz_host."

What type of backup are you trying to perform (Full profile, selective, both)? It appears that FEBE is failing while trying to "phone home" to Mozilla when getting your installed add-ons information. Try running FEBE Options > Advanced > Attempt to load and save extension data to see if it can complete without errors.

There is also a reference to 'getFirstPartyURI' failing. This is a Tor specific error. You say your Tor browser is based on Fx 38.5.0. Try installing and see if it makes a difference.

It also seems FEBE is balking at attempting to backup your permissions data. Try unselecting FEBE Options > What to backup > Backup permissions.

Interesting. If files can only be written to Home > Tor Browser perhaps you can create a new Fx profile in that location.

Start Fx from the command line with [path_to_Firefox_executable]/firefox.exe -p. This will open the profile manager dialog. Follow the prompts and create a new profile in some sub-directory of Tor Browser.

Install FEBE into the new profile and set the backup destination directory in some other sub-directory of Tor Browser.

If the FEBE Options > Advanced > Attempt to load and save extension data is successfull, the data should be in a file named 'febeExtensionData.json' in your new profile folder.
