Not working properly since Firefox 139 :( Selected texts are not changing :(

Not working properly, since Firefox 139 selected texts are not changing, please fix it...

My primary use is to convert text to Title Case, and the title case conversion in this extension is too crude to be really useful.
It would be better, for example, if it did not mess with words in all caps, at least as an option, so ACLU doesn't get converted to Aclu.

So sleek and easy to use, the Alt shortcuts are a lifesaver!

This is a fantastic tool, that I use many times every day, and always recommend to others.

An "Undo" feature would be nice, for the odd occasion when I have clumsily "selected all" a split second before using the add-on (CTRL-Z does not work in this case).

EDIT:
Change the Support site (Error404)

Very interesting addon:
I wanted just a "Case Changer" to replace an old good addon (not supported now)
and i discover a world of other subtle or funny text conversion!
Thanks a lot (and seems like it work perfectly...)....

Change case add-ons are absolutely essential for serious on-line work. This was one of my favourite add-ons, but it lacked an exceptions list. I had manually hardcoded one, until another add-on came up with exactly that feature. The lack of updates of this one also made me drop this in favour of the (better) alternative.

Very usefull

Very Good and more options than from the other Extension "Change Case". !

Not sure from the write-up if it is intended for use on text inside form input fields, but that doesn't work. It only changes text on the page itself.

Great addon! The only con I found is that it doesn't work in Wordpress text editor :/

perfect so far

Works very well, considering the variability of website design and implementation. Sometimes the Alt-key shortcuts work, sometimes not, but the job gets done, one way or another!

I love that addon

Does the job perfectly

Great & Simple Add-on But has stopped Working with the new update

I'd been using Case Change Tool 1.0.rev44.1-signed.1 by "Harry N" without any hassles for many years but this does not work in the latest version of Firefox.

I've now switched to TitleCase 3.1.1 by Joshua Pack. This does work and I've breathed a sigh of relief.

(I can't seem to get the Alt shortcuts working but maybe I'm not doing that part right...)
