    Thank you very much. Really.

    * 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 doesn't work at all! I do everything correctly, but whatever selections I make, it won't allow me to add a substitution! Always I get an error message saying "You must add at least one substitution and correct all errors." WTF!!!
  • 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.
    It's for good reasons that it is marked as not compatible with Android.
  • 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”
