Q. Where do I start?


First download the extension from here and install it to your computer.




Q. I try to install the extension to my computer according to your instructions but get the following error: Could not load manifest.json.


Please check that you extracted the [version].rar file correctly. Ensure that after extracting you have [version] folder --> manifest.json, background.js and some folders, not [version] folder --> [version] folder --> manifest.json, background.js and some folders.




Q. I still fail to install the extension locally, the error is: Could not load background script ‘background.js’. What to do?


First check that you extracted the archive correctly (see the question above). Ensure that you can actually see the background.js file in the folder to which you have extracted the extension. If you are absolutely sure that the extraction was correct, and the background file is in place, the problem might be with your antivirus program, which sometimes overreacts on .js files.




Q. The extension does not save pictures or emoticons. Is it possible to make it save them?


The extension allows you to save chats in 4 possible ways: as a plain text file, as a stand-alone .html file (with pictures and emoticons displayed), as a .csv file and as an archive (zip file). To change the settings you need to right-click the extension icon after you have installed the extension, and choose the Options menu item. This will bring you to the window where you can change the settings.




Q. Where can I find the saved file?


Open your Chrome browser, go to Settings -> Downloads. Download location shows the path where all your downloaded files are saved.




Q. The saved file doesn’t display the special symbols of my language. What do I do?


Change the encoding of the file. Open it in the Chrome browser, go to Settings -> More Tools -> Encoding, choose UTF-8. Check the ‘Auto detect’ option.




Q. Does the extension have access to my private data and account?


No, it does not, and it’s virtually impossible to do. The extension is open source, and its code can be freely studied.




Q. I have a big chat (60 / 100 / 400 thousand messages). The file that is saved doesn’t contain the whole conversation. Where is the rest of the chat?


If a chat is really big, Facebook might stop returning the data at some point due to a big amount of requests being sent, and returns a ‘temporary error’ instead. In this case, an incomplete chat will be downloaded. In general, you are advised to save your chat in parts by experimenting with the Date fields of the pop-up window.




Q. The ‘total amount of messages’ field says ‘not counted’. The Save button is unresponsive. How to fix it?


Here are some troubleshooting tips:

  • Make sure you’re saving from the correct URL - either https://www.facebook.com/messages or https://www.messenger.com/
  • Slowly toggle your chats, sometimes the extension just needs a refresh to start working.
  • Check that your chat is not muted, the extension won't work with muted chats.
  • Check that the chat you are trying to save is in the same folder as stated in the Options of the extension.
  • Try disabling any other extensions you might have installed. Sometimes some extension might prevent the normal work of the Chat Saver.
  • If your Chrome browser is heavily loaded with dozens of opened tabs, extensions and applications, try reinstalling and using a clean version of it.
  • If you don't want to reinstall your Chrome browser, try to first close all tabs and restart the browser. If it doesn't help restart your computer.
  • If you experience this kind of problem with a chat on a business page, try reloading the page.




Q. When trying to save my chat as a zip file I get the ‘Failed - No file’ error.


It might be an obsolete problem but if you still experience it, here is an explanation. This error is caused by a well-known Chrome bug (discussed here). Chrome would not let you save more than 500 Mb at once. The only way out is to save your chat in parts.




Q. I opened an old saved file and can see no pictures, the links seem to be broken. Why is it happening?


When you save your chat as a stand-alone html file (with the ‘ Save pictures, emoticons and other files locally ‘ field unchecked) all your pictures and other files can be seen in the file, but they are still kept on Facebook servers. The links to the pictures that are kept there have special tokens which expire after some time, and then the link can no longer be seen.

You have to either save the chat again or, if you really want to keep all your chat files on your computer, save the chat as a zip-file. For this check the ‘ Save pictures, emoticons and other files locally ‘ field. The links to the pictures in your chat will then point to the actually saved pictures in the created zip-file, and not to the ones kept in Facebook servers.




Q. Can I also save archived chats?


Yes, it is now possible. First, make sure you’re using the latest version of the extension. If you want to save archived chats or message requests, you should go to the Options of the extension, and choose the corresponding folder there. Press Submit to save your changes.




Q. I saved a chat with your extension, and now can’t see the whole of it in my Facebook account. Can the extension make changes to my chat?


No, the extension can’t change anything at all with your chats other than saving them. All your chats are kept at Facebook servers, and it’s a Facebook glitch if something isn’t shown. I personally experienced it on a couple of my chats, when they were not shown in full to me. After some time all went back to normal.
