Linker Checker Untrustworthy Rated 3 out of 5 stars

Although I believe this is a useful tool, I found that on the first page I checked, Link Checker reported a link as valid. However, clicking on link takes one to a different page reported as malware. Copying and pasting the link also gives a bad link. So use LinkChecker with caution.

I'm sorry you didn't have a good experience, however, the official LinkChecker you can download here has zero malware. I've noticed other non-Mozilla websites host extensions, modify them with malware, and make them available for download under the same name.

Please re-download this extension from here and try it again. If the problem persists it may be a bug. Otherwise, I pride myself on my extensions and would never stoop to malware. Feel free to email me directly anytime at if you want help troubleshooting.

Perfect Rated 5 out of 5 stars

does exactly what I need. I thought there was a problem when it tried to check telephone numbers I had set up with "tel:" links but I added tel: as an exception to the LinkChecker addon options and it ignored the telephone number link.
Have now sent a donation - well worth it

A must have tool for anyone that works on web pages.

Fast, intuitive, effective Rated 5 out of 5 stars

Thanks for this excellent little tool. I found this app by way of Deep Trawl's comparison of their product with yours <>. Their app is great for deep checking of an entire site, but for quick checking of specific pages I don't think LinkChecker can be beat. It will become a permanent tool in my toolchest so long as you keep it alive. And so I just donated $10 for that cause.

Export results Rated 5 out of 5 stars

This is an excellent add-on, I use almost everyday to validate the web page content.
Is there a way to export the results of the add-on to a notepad or a spreadsheet?
Please suggest.

Sehr gut das Tool kann ich euch nur ans Herz legen Top +++

Rated 5 out of 5 stars

Отличное дополнение! Серьёзно облегчает поиск битых ссылок разработчику сайта. Поначалу не совсем ясно, как с ним работать - аддон скромно сидит в браузере и ничем себя не выдаёт :) А работать он начинает, когда активируешь его функции на открытой странице через "Инструменты - Проверить ссылки на странице". Я доволен. Спасибо авторам.

I come to know about this Add-on by SEOmoz blog post. It's quite interesting but takes too much time when page contain too many links.

Very useful! Rated 5 out of 5 stars

This extension is very usful to check all links of a website. It still works with FF7, however, the developer does not seem to support it any more (the link to the project homepage is dead).

Rated 4 out of 5 stars

Great extension, but there are a few features missing:

1) The ability to pause, stop, and play the link checking process. Saves everyone bandwidth and other resources.

2) The ability to check only links you select. What's the point of the right-click menu otherwise?

Hope you consider them in future updates.

Inclusions Rated 3 out of 5 stars

It would really be nice to have an "inclusions" list to trigger "red" links (or defined colour) based on specific URLs (relative/absolute) as a way of QA'ing for links that must not be present. I don't think I've seen this on any other link checker and would be really helpful to have.

Great plugin. Please add test of selected links only and it will be perfect simplicity! :)

Rated 4 out of 5 stars

Very good - works simply and well.

Would be nice if you could configure to also flag 301s.

This review is for a previous version of the add-on (0.6.6). 

Wonderfull add-on Rated 5 out of 5 stars

Simple, but working awesome. I couldn't get the "Checked selected links" working, but still that doesn't take off my five stars. Good job!

This review is for a previous version of the add-on (0.6.6). 

Intranet usage Rated 4 out of 5 stars

It would be great if it could also check links to files shares on local network, other than just skipping.
Otherwise 5 stars for me.
