User Reviews
Pros
- Adds useful highlighting features similar to IDEs, beneficial for developers and code review.
- Persistent highlighting when scrolling, better than native Firefox highlight」「Simple and effective functionality that 'just works'.
- Native Mode improves functionality and speed, similar to old FindbarTweak addon.
- Select and highlight feature is excellent for quickly identifying instances on a page.
Cons
- Does not work inside scripted elements like search bars on Google/Bing.
- Page refresh resets all highlights, causing loss of persistent highlights.
- Lacks integration with Firefox findbar such as sending highlighted text to findbar and match case option.
- Lacks predefined keywords feature for highlighting multiple terms automatically.
- Interferes with some websites like Microsoft Teams, blocking access due to security policies.

Is HighlightAll Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
HighlightAll requires a few sensitive permissions. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on.
