Essential data is not the entire setup
Browser reset descriptions often emphasise retained bookmarks and passwords. A person may also depend on extensions, colour choices, permission exceptions or toolbar arrangements to watch comfortably. Those customisations deserve review before a broad reset, even when the browser keeps the account credentials.
The browsers have different scopes
Google says Chrome’s reset changes several preferences but is not a full reset of every setting, including some accessibility or font choices. Mozilla says Firefox Refresh removes add-ons and customisations and specifically warns that accessibility customisations may need to be added back. Do not apply one browser’s retention promise to another.
Write down the useful arrangement
Record the names of trusted accessibility extensions and the settings you rely on without exporting secrets into a public document. Note a working route to captions, readable text and navigation. This preparation makes a later comparison reviewable and reduces the chance of interpreting a lost support tool as a new service fault.
Use temporary diagnostics first when suitable
Mozilla recommends considering Troubleshoot Mode before Refresh. A temporary comparison can answer a question without immediately rebuilding the whole profile. It still changes several components, so its result should be interpreted carefully, but it provides another step before a more lasting reset.
Restore deliberately after the action
If a reset is warranted, repeat the original failing task and then re-establish needed accessibility and privacy preferences from trusted sources. Do not reinstall every old extension automatically without reviewing it. Report both the playback result and any changed access needs; a fixed error with unreadable controls is not a complete usable outcome.
