Yeah thanks for that. Even I am not so absolutely excited about opening 3'200 Websites just to get the Favicons down and show it up for less then two days... Then the sync taking place and overwrite all the bookmarks with the favicons again..

My question is, why the heck Opera manage this without a big theater since ever and FF is not able to get this really annoying little problem solved...

Syncing from browser to browser is a daily task and using an extra add-on just to get the favicons back is more then annoying. Nothing against your add-on. I moved back to the old school bookmark import (just for FF as its's anyway not my main browser) upload and renew the bookmarks by a html file incl. the favicons .... :)

Great for when you reinstall firefox cleanly and Want to refresh the icons!

Works great. It opens all favorites and updates the favicons.

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.

Nice!

But please add the ability to update individual bookmarks!

It's a major pain to update 3000+ favicons when a single bookmark has wrong favicon. (or atleast update toolbar bookmarks individually.)

Perfect reload favicons, thank you.

PRO's: Great add-on. I love the orange error; excellent detail in icons and reasoning behind each one makes things easily identifiable. Bonus for having the folder icon to indicate physical location of bookmark and the ability to update links. I have tested several others and this is the first one that doesn't crap out on me after checking 24K+ bookmarks. Side-note it took 5:53:08 to check all 24,653 bookmarks. UPDATE: Something else I noticed this seems to catch more bad links then others. I ran Bookmarks clean up which I found is the only other one that would run thru 24K+ bookmarks however it didn't flag as much; roughly 2500. I ran Checkmarks afterwords and it has caught about 2800+ more and so far I have verified 600 as being bad or potential risks.

CON's: I only gave it 4 stars due to lack of ability to select multiples to delete.

Wish-list:
Sort based on error and/or hide certain errors only showing specific ones.
Select Multiples. e.g. using CTRL+Click a check-mark box to select random ones and check-mark a box scrolling down then SHIFT+Click to check-mark another box in-turn check-marks everything in between.
Save previous search to pick-up later if browser was to crash.

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.
