It got reset to zero tabs stored when it had more than a thousand of them and I don't know what to do with that fact. And i feel dumb for removing OneTab before upgrading it. Add cloud storage as in uBlock to prevent it from happening, please. With a custom password only it will be perfect.
Open the link above directly to cover the installation of version 1.25. Note that it is not to uninstall version 1.26 before installation, but to cover the installation of version 1.25 directly on the basis of 1.26. Lost tag page groups can be retrieved. May the Force be with you!
