Still working. Unfortunate about the tag bug in firefox though, but I did not expect that to work given the clear warning.

A website I use changed their domain and I had a ton of bookmarks of that site. This add-on made it so easy and quick to change the domain on several bookmarks. So much better than manually changing the bookmarks one by one.

Very easy to use and understand. Replacing the domain on a bunch of bookmarks was as simple as typing in the old domain, typing in the new domain pressing scan bookmarks and then update bookmarks.

I received a warning but I think that because I wanted to change like 300+ bookmarks so depending on how many you want to change it might not show up

Very useful for replacing a changed or outdated domain name with the new domain name in the URL of in all your bookmarks for a particular site. Easy to use.

Did exactly what I hoped, thanks!

It wasn't explicitly noted that the regex version does show the proposed changes and then lets you explicitly enable/disable each one, which is exactly what I had hoped for!

All my reddit bookmarks are now explicitly old.reddit.

Easy to use. Does what promises.

Great! Uses a lot of system resources when having tens of thousands of bookmarks, but works absolutely perfect!
You save my life!

Very helpful. Many thanks to the dev :-)

Nice. Nice. Quickly became one of my most used extensions as I have multiple profiles synced across multiple Mozilla browsers (Firefox Nightly, Waterfox, etc.). Slowly approaching my ultimate bookmarks collection this way. (of course in no small part, facilitated with the convenience of your extension; your hard work!)

**My favorite benefit** :
Having development servers setup on my LAN, some of my BM titles represent stuff like 10.0.0.38 (or, whatever it might be). I've since switched to using named hosts, as my ISP service goes out frequently and the router assigned new IP addresses. Lesson learned, but a lot of my BM's (bookmarks, not the other bm) represented <-- past-tense, those IP's, in the title as well. So 10.0.0.38 easily becomes DevServerOne in both title and URL in one fell swoop.

Awesome!

Disclaimer: I may be crazy, but occasionally, I have a bright idea.
:)

This extension does its job as advertised, thank you for saving my hassle to replace hundreds of invalid urls to the working urls.

exactly what I needed. Used regex on my 17000 big DB, modifying 500 entries. Works OK.

What a life-saver!

I used it to replace a Nitter's instance by another one in 88 bookmarks, it is fast and reliable. Thank you!

Works for me, tried both RegExp and Domain Name modes. Just what I needed, thanks!
