The answer in 30 seconds

A page problem does not justify disabling protection everywhere. A list of blocked items shows protection activity, but does not by itself identify the cause of a failure.

Describe the symptom, inspect protection information and test any exception only for the affected site. Review extensions and sync separately.

Examples to adapt

A form starts working after one change

Record the change and assess whether a narrower setting is possible.

An exception makes no difference

Restore it rather than leaving an unnecessary weakening in place.

Follow the method

  1. 1
    Observe the problem

    Record the public URL, expected action and symptom. Check whether one component or the whole site is affected.

  2. 2
    Inspect protection information

    Read the shield information near the address. Compare it with Mozilla’s documentation before attributing the failure to a blocked item.

  3. 3
    Test a limited exception

    If appropriate, use the documented site-specific control, reload and repeat the action. Restore protection if it does not help.

  4. 4
    Check extensions separately

    Inspect permissions and temporarily disable one relevant extension. Retest before changing another variable.

  5. 5
    Review synchronisation

    If using a Mozilla account, inspect the chosen categories on each device and test a temporary bookmark before a major cleanup.

A checklist to keep

Use these checks to record what you found. The grid supports a decision; it does not make one for you.

ExceptionSite-specific testRestore if unhelpful
ExtensionsOne permission or toolTest separately

Read the checklist directly in the table.

What to check

Do not disable all protections at once.

Record exceptions retained deliberately.

More extensions do not always improve troubleshooting.

Common questions

Should I install several protection extensions?

Consider what each adds and which permissions it needs; overlapping tools can complicate diagnosis.

How do I identify the cause?

Repeat the same action while changing only one relevant setting or extension.
