The program is good but it doesn't work in some places like WhatsApp, Messenger, etc...

An essential, though flawed, workaround to a longstanding Firefox bug. The fact that Firefox doesn't honor MacOS text replacements has been on Mozilla's bug list for 8+ years. Doubt they'll ever fix it. This plugin does the same thing. Unfortunately, Apple won't let you even cut/paste existing Text Replacements, much less export them, so you'll have to re-enter them manually. The one nontrivial flaw is that it insists on inserting newlines after it makes the substitution, even if you didn't type a newline. If the original text was followed by a space, the substitution should be followed by a space. Doesn't seem to work that way.

I love this add-on, which I use in macOS. I copied my text replacement shortcuts, converted them into a JSON file, and imported them into TextFast. Now they all work on FF.

This add-on could be improved if the shortcut expanded with punctuation such as period, comma, colon, semi-colon, and not just a space.

Thank you for your work, Matheus.

Can you make it don't add space after it automatically complete the text? Good addon btw

I recently installed this Addon, and I am almost happy, except for the fact that when I reply to comments on Youtube videos and hit the space bar, it deletes the first letters of the recipient's name and puts the rest at the end of the phrase, plus it also retains my text shortcut at the end. Except for that, I really love it. Fix that and it would be 5 stars, because it does work fine when one writes on an empty line. Hope the developer fixes that, because I really like it.
