I don't feel it as my tool. I'm used to check errors online and there I can see all the messages in proper way. Here they are listed at the bottom and can't see all of them, yes there is a plus because when you click on a error/warning it shows you tha exact place of it but I can't say I got used to using it yet.
Even if you don't rely on its entire functionality and windows, it's good because this extension shows you if your page is correct or not. You are aware of all the errors/warnings during coding so the result would be - better code writing and developing the skills and knowledge.
I use it every day. I like it, because if you forgot something you would find out what would be the mistake. That way you learn to code more efficient and probably won't need validator in the future. Another positive thing is that you can check either through the extension or use both online validators by passing the current page to them.
It comes in great help for beginners in web developing.
We can work more efficient using this checker.
Very helpful HTML validator. I recommend to disable checking HTML for all pages to speed-up Firefox. You can check it in the code view (Ctrl + U).
Problem in the Firefox profile, subdir \tidy which contains the file 'spvalid.err'. Normally this file is zero bytes, with no data. The file had been 'restored' from another PC running a different o/s. Removed subdir \tidy, then re-installated Add-in which has repaired the issues and HTML Validator is now running as anticipated. Thanks to Marc for hint about Firefox profile.
I'ts a great tool. But, I have Firefox 29 and the icon don't appear on Add-on Bar.
Thanks for the feedback. You are the fisrt person to complain about it. And seen Firefox 29 is new. I would like to solve your problem asap. I have Firefox 29 on my machine but no issue.
Please do this:
- Click on the new menu toolbar of Firefox 29.
- At the bottom, click customize. Do you see the HTML Validator icon there ?
If yes, drag and drop it on the toolbar where it was.
- if not, right click on an empty space in the toolbar and click "customize..."
- the same list should show.
Whatever is the result, good or bad. Can you send me the result to my email "email@example.com" ?
- please add the OS and OS version
- the version from which you upgraded or after which change that
the problem happened.
- also if possible screenshot of the issue if it is still there.
My son likes this. Says he can do his job better with it.
As far as I know, it's the only add-on of its kind. Its automatic validation approach allows to detect that elusive unclosed tag that only shows up when you've loaded certain data (thus goes unnoticed with manual validation). Definitively, a must-have for webmasters.
The only major drawback is that it doesn't support HTML5 (it only provides a link to submit code to an online validator and such feature is provided by other extensions that do it better).
BTW, make sure you only use it on your own sites. There's no point in wasting memory and CPU cycles validating HTML at Google or Yahoo.
very often it hangs on different sites, so i close the FF with the Taskmanager. I cant say what site it is, one time it goes, other time it hangs
When I enable this addon, after several minutes Firefox stop to follow clicked links... I must close FF. However it still run in background and I must close it "really" via Task manager. No more problem when I remove the addon.
Can you mail me ? firstname.lastname@example.org. It would be interesting to know after which website visit that this is happening. There is a diagnostics logging to find this out. This is very probably related to Firefox bug https://bugzilla.mozilla.org/show_bug.cgi?id=839414
Fabulous tool. It's the biggest reason for my continued usage of Firefox.
But it lags to computer bad after a while, and sometimes just goes into a jquery error loop making the computer unusable unless firefox is close and the computer is rebooted, This is on a vista with firefox 23.0.
I am not sure of your issue. There are nearly no such issue reported since years about the extension. Except this firefox bug: https://bugzilla.mozilla.org/show_bug.cgi?id=839414
The extension contains a work-around to try to avoid it.
Also note, you need version 0.957 for FF 23.
I would be pleased that you send me a mail explaining what you see, what you found. (email@example.com)
Firefox 23.0 update causes a problem. The application claims "not in domain list". This can be circumvented by invoking the page source, but that means an unnecessary extra step.
Thanks for the problem report. It is a FF23 issue only.
A new version 0.957 will be available at home page http://users.skynet.be/mgueury/mozilla tonight (14 august 2013).
Then it will take some weeks to be approved and published in this site.
Very helpful and easy to use. Good results and advices are retrieved.
Very handy to have in the view-source!
Very good extension/add-on, can't live without it.
However, I'm using Waterfox since I want to take advantage of the 64-Bit technology (speed, performance, etc.) since there's only 32-Bit Firefox (except the Nightlies), and HTML Validator doesn't work anymore.
Any idea when we could expect a 64-Bit-compatible version of this add-on?
Quite useful when validating the page per line and get errors corrected.
One suggestion, could you please make it warp long lines then mark the line number? I know it's hard to achieve, but it could much better to check for HTML on a responsive screen.
Something wrong with extension. Use Firefox few years and auto update it to latest versions. This Validator always be in my set. At last time I can't update settings (can't press Ok in plugin setup menu) and see blank window in place where must be code inspection
Are you using Firefox in Russian, I have 2 other users reporting this issue in Russian only. It seems to be linked to the "-1" of a preference who is not recognized as number only in FF 16-17 in russian. Don't ask me why :-) Mail me to firstname.lastname@example.org for more info. Thanks
Ps: I got this from another russian user:
tidy.options.accessibility-check had STRING type in my about:config :
tidy.options.accessibility-check string -1
So I reset it and restarted firefox
After restart I have this
tidy.options.accessibility-check integer -1
It worked !
This is a must have add-on for web developers. Any chance it will be updated for FF 14 on OS X anytime soon?
Edit: I was able to update using the link below. The version displayed was FF 10.0x but I had no problem installing. Thanks!!!
The extension is compatible with FF14 on MacOSX.
Note that there is no version check in FF since FF11.

Please send a mail to email@example.com if it does not work.
essential add-on, use it practically every day
This is one of the most helpful extensions in my day to day work, along with Firebug. It's one of the things that brought me back to Firefox since it's available exclusively for it and it does such a good job.
For a long time I could not use it (on Linux 64bit) mostly because of Firefox breaking extensions on every release. I'm very glad it works again.
One feature I wished it had is an offline validator for HTML5, but maybe this will come too once the standard is closer to completion.
All in all, a great extension. Thank you Marc for taking the time to create and maintain this :)
With Waterfox there is now a well working 64 bit release of FireFox for windows and everything works very well, except this one extension. I like the extension and would be happy to be able to use it again.
