Replace html is very useful, thank you.

W addon, allows me to replace microsoft with microslop

Works as described. Replace method doesn't mess w/ Google Translated webpages' formatting, so I can use Stylus to get rid of those annoying paragraph indents.

I use this extensively, and lists get very long. A function to insert an entry at a selected location would save so much time. Currently using a Auto Hotkey script as a workaround to position entries.

Bug: After editing a list, sometimes the last list (or extremely rarely the first) gets overwritten with the edited list, losing all data. Unknown what causes this. Currently using empty lists as a buffer. New version prevents empty lists from being created, so as a workaround I have to import old blank entries (or just use the older version).

Usually works nicely, but need to explain how "match case" works. I want to substitute a word that can be either at the beginning or inside of a sentence. The case of that word must change accordingly.

Back with another question for you. Each "replace" entry contains several rows. I've entered additional requests in those fields, but it doesn't seem to work. For example: first row: ". White House" (with period and space) and second row: "White House". No replacements according to the second set of instructions occurs.

Keep up the good work.

Looked promising but does not work for discohook for whatever reason. I'm sure it works great for other websites but I can't be bothered to try when I don't need this feature for other websites.

The "Replace scripts" function can achieve powerful functions on some webpages, but it may interfere with their normal display effects on other webpages. Is it possible for the FoxReplace plugin to not use this function as a global setting, but instead allow personalized choices for each webpage? Thank you for Marc's work. I really like this plugin.

Works well but in march 2026 i can't edit iframe / textarea from TinyMce Editor. Why?

Exactly what I need, super fast, regexp, always there for me. Thanks heap!

The text replace functionality works well, but there is an issue with the changes to firefox which added vertical tabs and the 'show sidebar' setting.
If we switch to vertical tabs or enable the sidebar then it adds an icon for this extension, and it cannot be removed or disabled.
Please update the extension to fix this or tell us how to have the sidebar visible without the extension icon.

So far working as intended but I will need to use it a bit more to see. I found that to add a group of words to replace or have multiple words replaced AND to automatically replace when loading a new page you need to: 1). Go to manage extensions 2). Click the 3 dots next to this extension 3). Hit options 4). For auto replacing, at the bottom of the options page at "Other Settings", check the box for "Apply automatic substitutions on page load" 5). To add a list of words, hit the blue "Add" at the top 6). Select "Substitutions" instead of "URLs" 7). From there you can add your words and their replacement and change the name of the list too 8). Hit "OK" and it should work from now on!

Une extension que j'utilisais il y a bien longtemps et que j'avais perdue de vue. Je viens de la réinstaller sur mon ordi actuel, toujours aussi efficace.

Need checkbox :
start with,
end with,
keep case sizing,
and to take in consideration of lang="?" of html page pro list.

Auto case sensitivity, to adapt replacement to a term, without need to add multiple time the same term with letter variant (capital minuscule).

Like AutoHotKey ::TC0?:: ‖ ::TC0::

; ? (question mark) :
;--------------------
;The hotstring will be triggered even when it is inside another word; that is, when the character typed immediately before it is alphanumeric.
;For example, if :?:al::airline is a hotstring, typing "practical " would produce "practicairline ".
;Use ?0 to turn this option back off.

; C: (Case sensitive) :
;----------------------
;When you type an abbreviation, it must exactly match the case defined in the script.
;Use C0 to turn case sensitivity back off.

Adding new term in end of list is painful and could be reversed,

also sorting list would be cool,

and a checkbox to set a replace as important or not, to made them first.

To add U.R.L. filtering to prevent to act in some URL.

And to use import export, common standard format pro replace / correction, to be able to use them elsewere (Word, Write, other program of this kind).

i added this exstention to replace my deadname, didnt do shit

FoxReplace rocks. Been using it for about 11 years. People online grow dumber and more aggravating every year but this add-on keeps their crap off the screen, easily and reliably.

Simple clear and easy to use so far. Search and replace text, it does what is says. Haven't done extensive testing to see if there are any issues as others have reported, but has been pretty solid for me.

What is the privacy policy of this add-on? Will change the rating to 5 if addon is privacy-respecting.
