Hide the "Browser No Longer Supported" Bar in Google Drive

Google Drive, Docs, Sheets, and Slides can show a blue bar reading "This browser version is no longer supported. Please upgrade to a supported browser." The real fix is to update your browser—Firefox 123 or newer, Chrome 122 or newer, or Safari 17 or newer removes the bar completely. This guide is for the people who cannot update, usually because their operating system will not run a newer browser.

The bar takes about 50px off the top of the window on every page load, in Drive and in each editor.

First: Check Whether You Can Simply Update

Open about:support in Firefox, or Help > About in Chrome, and read the version.

• Below the versions above? Update if you can. That solves this at the source, with nothing to maintain afterwards.
• Already current? Something is overriding what your browser reports. A privacy extension or a leftover general.useragent.override setting in Firefox will trigger this bar no matter how new your browser is. Remove the override rather than hiding the bar.

You do not have to leave the ESR channel to clear Google's cutoff. Firefox 115 ESR is below it, but later ESR releases are above it, so a current ESR keeps the slower release cycle and removes the bar.

When Updating Is Not an Option

Some machines are genuinely stuck below Google's cutoff:

• Windows 7, 8, and 8.1, and macOS 10.12 to 10.14. Firefox 115 ESR is the last version that runs on these systems at all, so updating Firefox would mean changing operating system.
• Managed computers where an administrator controls updates.
• Linux distributions that pin an older ESR for the life of a release.

If that is your situation, the bar is not going away on its own, and the rest of this guide removes it from view.

Do Not Use the X Button

Closing the bar with the X removes it, but Google also drops keyboard focus onto the page body. Typing then goes nowhere until you click back into the document—which is why the page feels frozen or "inactive" after you dismiss the warning.

Hiding the bar with CSS avoids this completely, because the X is never clicked and focus is never moved.

Step 1: Install Stylus

• Install Stylus for Firefox
• Install Stylus for Chrome

Step 2: Create the Style

1. Click the Stylus icon in your toolbar, then Manage.
2. Click Write new style.
3. Under Applies to, choose URLs starting with and enter:

https://drive.google.com/

4. Click Add to create a second URLs starting with rule:

https://docs.google.com/

5. Paste this CSS:

/* Hides the "This browser version is no longer supported" bar
   in Google Drive, Docs, Sheets, and Slides */
.appsElementsBrowserSupportBannerRoot,
div[jsname="uXQRlc"][jscontroller="IsCPXc"][role="banner"] {
    display: none !important;
}

6. Name the style, click Save, and confirm Enabled is checked.

Refresh Drive or your document. The bar should be gone and the space reclaimed.

Why the Rule Has Two Selectors

Google ships the same warning component into Drive and into the editors, but compiles the CSS class names differently for each app. The editors use a readable class, appsElementsBrowserSupportBannerRoot. Drive uses a short generated class that changes between releases.

The second selector targets the component's internal identifiers instead of its class name, which is what makes one rule cover Drive as well as Docs, Sheets, and Slides.

Do not target the element's id if you inspect this yourself—Drive assigns it a counter value such as ucj-1 that changes on every page load.

Why the Bar Appears at All

Google decides this from the User-Agent string your browser sends, and shows the bar below a fixed version cutoff rather than a rolling window of recent releases.

That is why the warning can be misleading. A browser can still be receiving security updates from the company that makes it and sit below Google's cutoff at the same time—Firefox 115 ESR is exactly that case, which is why the message feels wrong to people running it.

Important Cautions

This method only hides the bar in your own browser. It does not change your Google account, your Workspace settings, or what Google reports about your browser.
