Very well to correct people's misspellings.
I would like the extension to correct the text on some url only.

Nice, but very heavy, 1.39 MB

* If you need to use simple search/replace - use "Replace" from erosman, 57 KB
* If you need to use automated search/replace (but without regexps) - use "Search and Replace" from rwanyoike, 36 KB
* If you need to use favorites, find/replace history and templates for cursor auto-inserting - take "Find & Replace for Text Editing" from Dalimil Hajek, 945 KB

A sanity saver! I used it to replace Trump with F***face and I can actually smile again. Thanks Marc!

This addon almost worked perfectly, but the replacements aren't working on page load with Azure pages. Have to manually apply the translations once the page is loaded. I was looking for an automatic solution. Otherwise, this addon has it all.

This doesn't work for Firefox Android. You cannot add anything because the keyboard does not show up when you tap on a text field.

This addon uses F9 as a hotkey to view the sidebar. The same hotkey used by Firefox for reader mode. As a result, whenever you press F9 to invoke reader mode, the sidebar is also activated. Please change the hotkey.

Great extension, extremely useful for language learners.

Awesome. I'm using it to replace the huge greeting on Google Hangouts with some generic text so I don't have to worry about opening Hangouts when I'm in a public place.

Works okay, but it's per-page. Have to redo this 1000 times? No thanks.

It's very good, and much better than word replacer II that I used to obliged to use on chrome.

Awesome addon, that does exactly what it says and more!
This is the only addon i found, that can replace links and urls on load automatically.

It doesn't work at all. The words I want to have replaced still show up on websites as usual. When I refreshed the website it replaced the words for a split second, and when the page finished loading the original words popped back...

TO THOSE GETTING "FIX ALL ERRORS" !

You have to press enter after filling out the "with" column.
It will then add your replace as a row and you will see a new row below it.
you should then be able to click apply/ok.

Works great, as far as I can tell. using to modify html on page load. Thanks!

I have just used this powerful add-on to fix the problems with my net bank's report pages, making them work exactly as I want them NOW - no need to wait for the bank to update their web app :-)

Good for simple texts. I missed the possibility to save/view replace history and to replace large content in text areas like youtube description videos.

Could not add filters，error MSG “You must add at least one substitution and correct all errors”

Could not add filters, got a cryptic error message with no indication what to fix.
