The new version is now available on addons.mozilla.org:
https://addons.mozilla.org/addon/45281.
Here is what I changed:
Changes
- Now it's possible to read the book content in several columns, so it's easier to read if the lines are long. This can be configured in the preferences.
- A button for opening the ePub-catalog can now be added to the Firefox toolbar.
- Plugins (e.g. for display of SVG images) can now be enabled in the preferences.
- Firefox 4.0 is now supported.
Bugfixes
- Sometimes the book content wasn't displayed with the configured font size.
- Font size changed via the zoom-buttons was reset when the Firefox tab was changed.
- On some websites the filename of ePub-files was not displayed in the Firefox "Save as" dialog.
- In some cases "ePub-file corrupted" was displayed instead of the loaded page (e.g. login).
As always, please let me know if you experience any problems and for the case you like the new features, I'm also very happy to hear from you
