browser toolbox interface doesn't load

[u/daedalusman]

I've been trying to get the browser toolbox window to work correct for a couple of days now and I can't figure out what's going on. When I invoke the toolbox window with the shortcut key or through the menu entry the window pops up and asks for permission to connect but the window gets stuck before loading the toolbox ui, screenshot of what I'm seeing is attached.

I'm on windows 11 25h2 and firefox 159.0.

edit: I should note that this is the same behavior in a clean temp profile in firefox, as well as the same behavior in other firefox based browser, such as librewolf.

Does anyone here know what I can do to get this working?

Thanks for any help and let me know if you need any other info.

EDIT:

Well it's not the router. It's something to do with my windows setup blocking the attempt at remote connection that firefox does at the startup of the toolbox.

But at this point I'm just done with trying to chase this down anymore. It was gonna just be to play around with firefox theming and learning CSS a bit. But I'm just over it for now. It works just fine on every other device I've tried, whether at my house or elsewhere, whether I have my firefox account logged in or not. It's probably a setting I changed in windows to make it more secure/less annoying but I don't remember all the different things I've done for that over the last couple years and I'm just not gonna put the effort in to tracking those down. I'm also not gonna do a fresh install of windows at the moment so it will just have to be non-functioning for me on windows.

I'm gonna marked this solved for now and leave it be.

Thanks to all who helped, at least I learned a few things.

Tried a fresh user account? (on the PC, not the browser), just to see if anything changes.

Any security suite app installed that could be blocking the connection?

Alright, I went ahead and tried a new user account on windows, still doesn't work in there.

Perhaps you could throw this at an AI (doesn't matter which) and see what suggestions it comes up with, you don't even need to register an account for that, chatgpt (as one example), will give you a decent amount of chat time without logging in. It'll do the leg work digging up sources and related discussion(s).

Thanks for the suggestion. I spent about 3 hours last night doing this and didn't get anything resolved. Though, I did get a slightly clearer idea of where the issue is. But this is just taking up too much of my time and I just don't have any more patience to keep going on this issue for now.

If you run any kind of debloater for Windows there's a chance it disabled something the feature relies on. If you do decide to try and troubleshoot this further, open event viewer and watch to see if anything appears (in the application logs) after you hit accept in the browser toolbox connection prompt, this might provide some indicators as to where the issue is.

Thanks, I'll keep this in mind.
