@eight04, I guess dropbox changed their API so maybe you can update your db-to-cloud? FWIW, here's how Violentmonkey did it.

The screenshot looks like a login error so I guess something went wrong in token manager or launchWebAuthFlow.

I can't reproduce on Windows 10 + Nightly 117.0a1 + Stylus 1.5.33

Anything I can do to help debug besides building and debugging locally?

[tophf]

Our extension is not using a build system for the source files, which are the same as the shipped version. Try clicking Inspect in about:debugging and see what's printed in console, check the network panel, set a breakpoint in

stylus/vendor/webext-launch-web-auth-flow/webext-launch-web-auth-flow.js

Line 193 in 1da00a9

if (details.frameId || details.tabId !== tabId) return;

then press F10 to verify it successfully completes to the return a few lines below.

Also disable all other extensions temporarily.

I get the same thing migrating from windows 7 where it worked on google drive, now to windows 10 (yet surrendering), latest chrome there and max version on windows 7.

I am using the same google chorme profile and account. upon syncing via extension options, it does present the right google pop up window permission thingy, with correct account, and acknowledging existing permissions, but then fail..

will attempt from windows 7 to sync again.. in case broken there too...

Stylus Extension wants additional access to your Google Account

then upon clicking continue i get the following.

This site can’t be reachedclngdbkpkpeebahjckkjfobafhncgmne.chromiumapp.org’s server IP address could not be found.

I'm getting this same behavior. I can't sync to Dropbox or Google Drive. Firefox console says:

Content-Security-Policy: The page’s settings blocked the loading of a resource at inline (“default-src”). injected.js:1:9445

Still works for me, so I don't know what's wrong. It may be caused by some setting in the browser or another extension. Try removing the Stylus extension and install it again. Try installing it in a new browser profile. Don't forget to click the export button in the manager first.

It appears that it's only a problem with all the other "more secure" browsers based on Firefox. Like Floorp is to Firefox what Brave is to Chromium. Floorp, Librefox, Waterfox, etc. all of them won't sync. So it's some security "feature" they have modified in some way.
Edit: Stylus is now having trouble syncing with Dropbox in those browsers, too. Since it's a completely unrelated addon, it's definitely something the "enhanced security" browsers have added or changed.
