How do I download my files from
Firebase Studio?
To download your files as a zip file:
Right-click on any directory in the Explorer pane and select
Zip and Download.
To download everything in your project directory:
Select File > Open Folder.
Accept the default /home/user directory.
After the files load, right-click your working directory and select
Zip and Download. If using
the App Prototyping agent, your working directory will be studio. If
using a template or uploaded project, this will be your project name.
When prompted to rebuild the environment, click Cancel.
After your download completes, re-open your working directory from the
File menu to move back into your workspace.
Third-party cookies aren't enabled.
Before you get started, you might need to enable third-party cookies for your
browser. Firebase Studio requires third-party cookies in most browsers
to authenticate workspaces.
Click the visibility icon in the address bar visibility_off to open the Tracking
Protection panel. Turn on the Third-party cookies setting to
temporarily allow third-party cookies. This enables cookies on
Firebase Studio for 90 days.
You don't need to enable third-party cookies for Brave. Open
Firebase Studio.
Why does Firebase Studio need
third-party (3P) cookies enabled?
Firebase Studio needs 3P cookies enabled since we render an iframe from
one domain (a subdomain of cloudworkstations.dev) on another domain
(studio.firebase.google.com), and 3P cookies enable secure cross-origin
communication.
While opening a workspace, the message Unable to forward your request to backend. Couldn't
connect to a server on port 80 appears.
Wait approximately five seconds and refresh the page.
How do I view the request per
minute quota for my auto-generated Gemini API key?
You can view the quotas associated with your auto-generated API key on
the Generative Language API Quotas and System Limits page in the
Google Cloud console.
My preview doesn't load, but I
can't find any issues in code. How can I restart Firebase Studio?
If Firebase Studio isn't refreshing properly (typically as a result of major
refactors, or changes to your environment dev.nix file), open the command
palette
(Cmd+Shift+P on Mac or Ctrl+Shift+P on ChromeOS, Windows, or
Linux) and run the Hard Restart command. If that doesn't work,
try running the Rebuild Environment command.
My workspace is not
responsive, all I see is a blank screen when it loads
If your workspace is not responding, you can try resetting the VM. To do this:
From Firebase Studio, click the
More ( more_horiz ) menu,
then select Reset.
When prompted, click Reset again.
Re-open your workspace.
While creating a workspace, I see a
message, Whoops...We need to start a new VM, and the UI hangs after
that.
Firebase Studio maintains a warm pool of VMs used to provision
workspaces on demand. When the pool runs low, the workspaces are
provisioned after a new virtual machine is started. The process can take
time (sometimes up to five minutes) but eventually succeeds.
When
creating a workspace, I receive an internal error occurred.
In most cases of internal errors during workspace provisioning, refreshing the
page after a minute or so should get you past the error and into the workspace.
How many workspaces can I
create?
The Firebase Studio no-cost plan is limited to three workspaces per user.
You can increase the number of workspaces you can create up to 10 by joining
the Google Developer
Program.
To upgrade to 30 workspaces, subscribe to the Google Developer Premium
Program.
My workspace loads, but the
emulator is blank.
We're actively improving the reliability of our cloud-based emulators. If a page
refresh does not fix the problem, report the issue to Firebase
Support.
Firebase Studio workspaces
have a Flutter version that is incompatible with my project.
You can upgrade or downgrade the version of almost all pre-installed
software inside a workspace just as you would on your local machine (using
apt-get or brew). You can upgrade or downgrade software in your workspace,
but installed software is not persistent across sessions. We recommend
including all required packages in your
dev.nix file.
We're actively working to improve Flutter version management in
Firebase Studio.
I shared my workstation URL with
someone, but they cannot see it.
You can only share a workspace URL with users that have access to the workspace.
Users without permission see an error when trying to visit the URL. Be sure to
explicitly share the workspace with them.
When I share my workstation, what
can my collaborator see?
Users added to your workspace have complete access to the VM's entire file
system, which may contain sensitive files like private keys and access
tokens that are stored on disk. Only share your workspace with
people you trust. While this approach helps other users view the exact
state of your workspace, it means that they see everything on your
workspace.
I shared my workspace;
why can't my collaborator publish or monitor my app?
Users added to your workspace may not have permission to its underlying Firebase
project which powers the "App overview" publishing and monitoring features. To
grant them permission to your Firebase project, see Permissions and access to
Firebase
projects
Can I use frameworks that
Firebase Studio does not have a template for to build my application?
Yes! You can customize your environment to
work with just about any framework or language in Firebase Studio.
What target directory should I
select when publishing a Flutter app to Firebase Hosting?
Choose the build/web directory. This directory should contain an index.html
and all the static assets needed to render your web app after the app is built
successfully (via flutter build web).
How can I set up my app's backend
on my workspace so that my frontend can communicate with it?
You can temporarily publicly open the TCP port your backend server is running on
to make it easier to develop your frontend and backend separately, across
different workspaces:
Start your backend or API server either manually in a terminal, or as part
of your dev.nix file's preview
configuration or onStart lifecycle hook.
Click the Firebase Studio icon in the activity bar (on the left by
default) to open the Firebase Studio panel.
Expand the Backend ports section to see a list of running servers,
including their port number and process ID (PID).
Click the Make
public icon (a lock) to the left of the port number.
Click the Copy URL icon to the right of the port number to copy its
fully-qualified URL.
You can now reference this URL directly (for example, with a fetch call)
from your frontend.
I closed my preview tab. How do
I bring it back?
Open the command palette using Ctrl+Shift+P (or Cmd-Shift-P on MacOS), then
select Firebase Studio: Show Android preview or
Firebase Studio: Show web preview.
What is Code OSS?
Code-Open Source Software (Code-OSS) is an open-source project that's the core
layer of VS Code. Code-OSS is available on GitHub under the standard MIT
License, and is where Microsoft develops the VS Code product.
How can I prevent my code
completions and Gemini chat prompts from being used as training
data?
To block the use of your prompts and responses for model training, do not
use the App Prototyping agent, and do not use Gemini in Firebase within
Firebase Studio. To block the use of your code for model training,
turn off code
completion
and code
indexing
in your Firebase Studio settings.
How do I submit a feature
request or feedback on an issue I encountered?
If you encounter an issue while using Firebase Studio or have a feature
request, contact Firebase
Support.
I was using a particular feature in
Firebase Studio but I can't find it anymore. Why was it removed?
Some of the features in Firebase Studio are experimental. We value your
feedback and actively use it to inform our current and planned feature set,
periodically removing features that aren't living up to your expectations
or our own. If there are features you'd like to see in your ideal version
of Firebase Studio, send us
feedback. We want to hear from you!
I was unable to create a project
When provisioning resources like a Gemini API key or deploying to
Firebase App Hosting, a project is automatically provisioned for you, based
on the name of your Firebase Studio workspace.
If you receive a "Failed to create a project" error:
If your Google Account is part of an organization, it's possible that you
don't have permission to create Google Cloud projects or that you've met
your project quota limit. Contact your administrator for assistance or see
Creating and managing
projects.
If your Google Account is not part of an organization, you may have met your
Google Cloud project quota limit. Request a quota
increase.
