Q. Where do I start?
If the link does not function for some reason, use the spare one here and install the extension locally to your computer.
Both versions are totally equal and functioning, I have made the spare local version due to possible problems with the Store, which sometimes can unexpectedly ban extensions.
Q. I try to install the extension locally 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.
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.
No, it does not, and it’s virtually impossible to do. The extension is open source, and its code can be freely studied.
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.
First switch between your chats, sometimes the extension just needs a refresh to start working.
If it does not help, check that your chat is not muted, the extension won't work with muted chats.
If it still does not work, check if there is any error in the Developer Tools window (you can open it by pressing F12) when you’re switching between the chats. Send me a pm with the body of the 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.
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.
You have to explicitly select the chat you want to save before opening the popup window. Check the URL of the page, it has to contain words like ‘threadid’ and ‘timestamp’.
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.
