The browser may report Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node. In one documented minimal reproduction, changing two separate conditional text expressions into a single ternary avoids the error. That is a targeted workaround to test—not a universal fix for every translated React interface.
Why can translating a page break React?
React creates and updates DOM nodes according to its render tree. A browser translator or another extension may change the page outside that rendering process, replacing or restructuring text nodes. React can then attempt to remove or insert a node based on a parent-child relationship that translation has already changed.

This is a DOM ownership mismatch, not simply a problem with translated wording or a language code. It can surface when a later interaction causes React to update the affected content. A related browser message is Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted is not a child of this node. In other words, insertion can fail as well as removal.

What does the reported React example look like?
A React issue opened on November 13, 2017, describes a Chrome page using React 16. After translating Japanese text to English, clicking a checkbox triggers the removeChild error. The example renders two mutually exclusive bare text values with separate expressions:

- Magic Capture catches the moment as you live it: With just one tap, Pixel 11 Pro captures video and photos, and automatically edits, crops, and unblurs a curated collection, ready to share – and you get the memory of how it felt to be in the moment
- Two new cameras for more brilliant photos: A larger telephoto sensor captures 30% more light for clear, beautiful photos and videos, even in the dark[3]; Pixel’s longest zoom ever helps you capture details from impressive distances[4]
{this.state.checked && "選択済み"}
{!this.state.checked && "無選択"}In that reproduction, the issue report says to express the choice as one conditional expression instead:
{this.state.checked ? "選択済み" : "無選択"}This is the lowest-impact code change to try when your component has the same pattern. The report demonstrates it as a workaround for that specific reproduction; it does not establish that ternaries prevent all translation-related DOM errors.

Can this happen in newer React versions?
Yes, reports are not limited to the React 16 reproduction. A separate report filed in 2023 against React 18.2.0 describes translating or programmatically clearing a component’s contents, then triggering a render that removes it. The removeChild failure could leave the page blank; that report was closed as a duplicate. Another report describes both insertBefore and removeChild errors after Google translation.
These reports show the same class of failure across different scenarios, but they do not establish which current React releases, browsers, or translators are affected in general.
How should you diagnose the error?
- Check whether translation is a trigger. Reproduce the interaction with the page untranslated, then translate it using the browser setup where the error occurs. Also check whether a DOM-mutating extension is active.
- Identify the state change that fails. Test the action that adds, updates, or removes the translated text, such as toggling a checkbox or removing a component.
- Search for both DOM errors. Look for
removeChildandinsertBeforein console output and error monitoring. Either can indicate that React’s expected node relationship no longer matches the live DOM. - Reduce the case. Isolate the affected component and its state change. If it contains separate conditional expressions rendering mutually exclusive bare text, try the single-expression form shown above and repeat the translated interaction.
- Retest both states. Verify the proposed change with translation on and off, and exercise the relevant additions, updates, and removals. A result in one interaction or browser setup does not validate other paths.
What are the mitigation trade-offs?
| Approach | Preserves translation? | What the evidence supports | Main trade-off |
|---|---|---|---|
| Use one conditional expression for mutually exclusive bare text | Yes | Reported to avoid the error in the original minimal reproduction | Must be tested in the actual component; it is not established as a general guarantee |
| Suppress translation in an affected subtree | No, for that subtree | Mentioned in the original issue discussion as a way to avoid translator mutation there | Users cannot translate that content through the invoked page translation |
| Swallow DOM exceptions with a monkey patch | Not necessarily | Discussed in secondary technical material, but not established as a reliable repair | Suppressing an exception does not reconcile React’s expected tree with the visible DOM; updates can target detached nodes and leave the page stale |
Translation suppression is a product and accessibility decision, not a transparent repair. Likewise, catching or swallowing removeChild or insertBefore errors can hide the symptom without restoring a consistent interface. Avoid a global patch unless you understand its effects and have tested the resulting UI.

The documented conditional-expression workaround applies to one minimal case. The reports do not prove a mitigation across all React releases, browsers, translators, extensions, or application interactions. Reproduce the failure with the app’s actual browser setup, test the narrow code change where it fits, and verify that the visible interface stays correct after translation and subsequent state updates.
