Extensions can improve productivity and privacy, but they also modify browser behavior and may interfere with complex secure workflows.

Safety note: This guide is informational only. It does not host a sign-in form, collect credentials, or provide account recovery. Use only the official service address supplied by your organization.

Script blocking

Some extensions prevent scripts that control navigation or verification.

Cookie controls

Privacy tools may block cookies needed to maintain session state.

Password extensions

Password tools can alter fields or overlays in ways that conflict with page scripts.

Controlled testing

Use a private window or temporarily pause one extension at a time.

Restore protections

After testing, re-enable normal protection and use an approved configuration.
