Have you tried Save File As

Do you still have the Old Firefox Data folder on your desktop from the Refresh? You may be able to research old extensions in there, as follows.

Click into the Old Firefox Data folder on your desktop. Then you should see:

• a semi-randomly-named folder, often with "default" in the name
• inside that, an extensions folder
• inside that, various files and/or folders for your old extensions

The challenge is that extension files/folders often are named using unique id's instead of friendly descriptive names.

If none seems obviously useful, try this instead:

Return to the main level of the old settings folder and find the file extensions.json and right-click > Copy it. Then right-click > Paste in a blank area of the list. Windows should now show extensions - Copy.json. You can rename that with a .txt extension to access it more easily using a text editor.

In the file, search for any part of the extension's name and you should see information such as the following (example is Adobe Create PDF extension):

{"id":"web2pdfextension@web2pdf.adobedotcom","syncGUID":"v4hJ7nJBAhrE","location":"winreg-app-global","version":"2.0","type":"extension","internalName":null,"updateURL":null,"updateKey":null,"optionsURL":null, "optionsType":null,"aboutURL":null,"iconURL":"chrome://web2pdfextension/skin/C_AdobeLogo_48x48.png","icon64URL":"chrome://web2pdfextension/skin/C_AdobeLogo_64x64.png","defaultLocale":{"name":"Adobe Acrobat - Create PDF","description":"Converts a web page to PDF","creator":"Adobe Systems Incorporated","homepageURL":"http://www.adobe.com/"},"visible":true,"active":true,"userDisabled":false,"appDisabled":false,"descriptor":"C:\\Program Files (x86)\\Adobe\\Acrobat 11.0\\Acrobat\\Browser\\WCFirefoxExtn","installDate":1389397098333,"updateDate":1437178060195,"applyBackgroundUpdates":1, "bootstrap":false,"size":286843,"sourceURI":null,"releaseNotesURI":null,"softDisabled":false,"foreignInstall":true, "hasBinaryComponents":false,"strictCompatibility":false,"locales":[],"targetApplications":[{"id":"{ec8030f7-c20a-464f-9b0e-13a3a9e97384}", "minVersion":"4.0","maxVersion":"*.*"}],"targetPlatforms":[],"multiprocessCompatible":false,"signedState":0}

Note: turn on word wrap if necessary, since otherwise it's one long line.

If you skim through the parameters, hopefully you can find the full title.

By the way, if the document title is blank, then Firefox will use the file name. Which means you could try a hack to address this situation, which is to blank out the document title or change it to something you prefer. Probably the simplest way to do that is using a bookmarklet. That's a short script you save on the Bookmarks Toolbar or Bookmarks Menu so it's easy to run. Here are two examples:

(1) To blank out the document title -- the URL then should appear on the tab

javascript:void(document.title="");

(2) To display a dialog that lets you edit the file name and make that the title (in this example, it adds the site at the beginning, e.g., support_mozilla_org)

javascript:var fn = window.location.pathname.substr(window.location.pathname.lastIndexOf('/')+1); var p = prompt('You can edit the new title to your liking (to use only the actual file name, click Cancel):', window.location.hostname.replace(/\./g, '_') + '_' + fn); if(p) document.title = p; else document.title = fn; void 0;

To try out either of these, here's how you create a bookmarklet:

Select and copy (Ctrl+c) the script code you want to use.

Right-click a spot on the Bookmarks Toolbar or Bookmarks Menu where you would like to add the button, and choose New Bookmarks.

Click in Location and paste (Ctrl+v) the script code.

Click in Name and assign something convenient like ClearTitle or EditTitle. Then click the Add button to save the bookmarklet.

To test it out on a page, just click. If you would like something more customized for that particular site, there's a good chance it's possible, so feel free to ask.

Thank you! Once I'd added the "Title Save" extension, the "Save File As" option showed the original filename (which is how I want to save the files). Without that extension, "Save File As" showed the title, necessitating much tedious & error-prone cutting+pasting.
