Just the extension I was looking for. I have thousands of bookmarks, some dating back almost 20 years. I was never too keen on so-called "tags" to identify my bookmarks, and there was no such concept some years ago. Therefore, I heavily rely on the presence of a favicon to know where a bookmark is coming from and to classify them (a neverending task), as well as to identify broken websites.

In the past, I had to restore Firefox profile from backups because of various crashes, breaking favicons in the process. While keeping bookmarks was my main concern, it did detract from my experience with Firefox, not knowing the original website. Some websites also don't use clear webpage titles, further obfuscating their origin.

This application is very simple: I open it in the side panel, then click "Play": it will proceed on re-loading each bookmark five by five, closing them after timeout, catching favicons in the process and detecting broken bookmarks. Sure, it will use lots of CPU for a while, but probably won't saturate the RAM or crash Firefox. You can change the rather conservative default settings if you have a really powerful computer so as to speed up the process. One caveat: DO NOT close the side panel or switch to another view there: this will stop Checkmarks and you'll have to start all over again. My advice: let it run overnight.

Perfect reload favicons, thank you.

Like how it does the two things that are associated with organising bms.. 5 ⭐⭐⭐⭐⭐'s

Very good

For a visual person like me, this addon is a lifesaver. For a digital packrat like me (with close to 70,000 bookmarks), this addon can seem tortuously slow at times. Thankfully though, there's a setting that lets you only focus on certain directories at a time, so you don't have to do everything all at once.

Paul, as of right now, you are my hero lol

Livesaver, thank you for this! Worked a treat after having to restore my computer and reload Firefox.

Renewed all my missing favicons. Great!

Обновились закладочки, ушло 3 часа 48 минут... охренеть.
но деваться пока не куда...

Must have for new firefox install. It work perfectly and doesn't overflow RAM because it close the tab once the icon is loaded.

This plug in can restore all the missing favicons in Firefox bookmarks. I just used it on two different machines and it worked like a charm.
