User Reviews

Change Case is a simple, useful Firefox add-on that converts text case and helps prevent CAPS LOCK mistakes. Users praise its straightforward functionality and broad applicability, including on social sites. However, its reliability varies across sites, it can introduce trailing spaces, and it can struggle with multi-line text or dynamic pages. Overall, a handy tool with room for improvement in site compatibility and edge-case handling.

Pros

Does exactly what it’s supposed to do: converts text capitalization and fixes CAPS LOCK mistakes.
Simple and easy to use, and generally effective.
Useful across many sites and contexts (works on social sites and comments).
Long-lived and continues to be available for Firefox, maintaining usefulness over time.

Cons

Not reliable on all websites; performance varies by site (Gmail, freetm.com, Twitter/Disqus on some pages).
Can add a trailing space at the end of sentences in some cases.
Does not always handle multi-line text or text spanning lines.
May be blocked or less effective on pages with dynamic JavaScript content.

Recent reviews

Greatest tool ever for morons who accidentally hit CAPSLOCK Key instead of Shift key and then type sentences or whole paragraphs before they notice all the capitalization is reversed

Very useful extension, I suggest to add the option "Capitalize only the first letter" of a sentence.

Is Change Case 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.

Change Case requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Change Case has earned a fairly good reputation and likely can be trusted.
