Can you make a shortcut for example - Alt+1 - for Sentence case too? (but not Alt+S, this activates the help menü in my browser :) )

Works great! Thank you for this.

It works... but it doesn't. I select the text I want to transform in the browser form, I right-click the mouse, I change the case in the addon, the text's case changes. But after I bring the mouse away from the changed text, its orignal casa is back.

It works, thx

It's an excellent extension but it lacks two of the tools I use the most on the website version: "Text Replacement Tool" and "Sort words alphabetically". It would be better if you can add all the missing tools at once, instead of having people to ask about every tool on the website.

By far, the best case converting tool for Firefox. It's one of those extensions that should be part of Firefox's code! Works both on HTML text and in form fields. It has a user defined exception word list for those that shouldn't be capitalized when converting to Title Case. There're 4 hotkeys for quick conversion (Title, lower, UPPER and Capitalised cases), which can be assigned from Firefox's extension setup to any free key combinations.

Very excited to see this add-on as we are long-time users of this tool. The reason for the four stars is that we most often use Title Case; any chance you could add it? It would be such a timesaver! (At present, for those tasks we are still having to paste text into the website tool and copy it out.)

Update: with addition of Title Case, we are very happy! Updated to five stars.

I was unaware of this tool, and amazingly it can save your day more than once. Forgetting to enable/disable CapsLock is no longer a hassle of deleting EVERYTHING and retyping it, just to mention a few of its utilities. It is ideal for editors and developers. It is a pity that many users are unaware of the existence of this excellent utility.
