Hi Fabian, I totally understand the problem with bookmarks. Firefox saves the extension link because it is the URL in the address bar. I am planning better bookmark support in near future. Thanks for using doqment!

Hi Fabian, thanks for the review. Once you select dark mode, it applies automatically for all PDFs. Please open an issue at 🔗https://github.com/shivaprsd/doqment/issues🔗 if this is not happening.

There is already the option to set the Default zoom level; please go to Manage Extension ➡️ Preferences and scroll down to PDF Viewer Options.
