This was reported back in Aug 2018. Check to see if this problem still exists. If yes, investigate why this is happening and report back here. Cross-platform problems are often complex to fix, so do not try to fix it without first assessing and reporting on the problem here.

The issues seems to be something to do with MacOS specifically where in the filename with extension is not allowed while saving a file using FileChooser API.

Code changes has been done accordingly to avoid the above

Testing Steps

1. Open IGB and add a bookmark
2. Choose Export Bookmarks from the Bookmarks menu.
3. Try saving html/txt file with and without extension in the filename.
4. Repeat the above steps for all platforms - Windows, Mac, Linux.

I have reviewed the code and tested on macOS. Exporting a bookmark without specifying an extension defaults to saving it with an html extension, as expected with the new changes. Moving forward, however, testing on windows and mac will still be needed.

Merged. Master branch installers have built and are ready for testing.

To test:

• Check functionality on all platforms

Tested on macOS, Windows, ubuntu for both scenarios involving each txt and html using the latest built master executables.
