+## Known Problems
+### Firefox not interrupting downloads (Issue [#43](https://github.com/slgobinath/uget-chrome-wrapper/issues/43))
+If Firefox does not interrupt the downloads but `Download with uGet` works, delete the `handlers.json` from the following path.
+
+```
+~/.mozilla/firefox/mwad0hks.default/handlers.json
+```
+
+You may have a different folder name instead of `mwad0hks.default`. Firefox Nightly users may have `firefox-trunk` folder instead of `firefox`.
+
+### uGet does not capture the downloads in Windows (Issue [#43](https://github.com/slgobinath/uget-chrome-wrapper/issues/43))
+
+Ensure that `uget` directory is directly under the `C:\` drive and the `C:\uget\bin` directory is added to the environment variable `PATH`. Also start uGet manually (recommended to add to the system startup) before downloading any files.
