could you please make it warp long lines then mark the line number Rated 5 out of 5 stars

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.

Problem Rated 5 out of 5 stars

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

Russian Firefox ?

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 mgueury@skynet.be 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 !

Must Have Rated 5 out of 5 stars

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!!!

OSX

The extension is compatible with FF14 on MacOSX.
Note that there is no version check in FF since FF11.

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 :)

Please add Windows 64 bit support Rated 5 out of 5 stars

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.

Poor HTMLValidator, poor Marc.

Firefox has problems but all we notice is that an extension is not prepared to cope with the bad attitude of the Firefox-developers.

I love this extension and will rather stop using Firefox than do without HTMLValidator!

Having overcome the worst trouble with the 10.x releases of the browser, I am glad to say, that the extension works fine under Linux 64Bits.

Rápido, cómodo y simple.
Verifica la sintáxis de una página HTML o XHTML desde el mismo navegador, tan sólo basta mover la vista a la esquina del navegador y saber si nuestro sitio tiene una correcta sintáxis o no, nada de salir de Firefox, validar en el sitio de la W3C o usar oscuros programas de MS-DOS para validar nuestros sitios, tan solo mirar a la esquina de la ventana alcanza.

Muy simple y totalmente práctico.

Problem with new Firefox Releases Rated 3 out of 5 stars

Really good tool and i like it very much.
But with every new Firefox Major Release it does not longer work and we have to wait for an update.
Can you please rewrite the tool in that way that it is no longer depending on upcoming Firefox Releases?
Thank you so much.

This review is for a previous version of the add-on (0.9.1.2). 

It is already done. Look at version 0.951. Now does not complain to me but to Firefox and Chrome who created this maintenance nightmare due to 2 wrong decisions. The fix was to rewrite a major part of the binary and work still need to be done on other platforms.

I love this tool. I really appreciate the work you've done.
I only hope that FF will stop with this ridiculous updates.

Please update this Add-ons. I'm looking forward to. Please publish a compatible version. I would like to thank everyone who contributed. This is a very useful software.

Config file ? Rated 5 out of 5 stars

What a great addon !

I've done a configuration (hidding some errors or warnings), do you where the config file is saved ? I need to share my config.

Thanks a lot

Config

Type About:config in the URL of Firefox and look for tidy.
I am not sure maybe the real value is today, firefox changes too fast.

fatal error Rated 5 out of 5 stars

on FF7
FATAL ERROR : The dynamic C library contained in the extension file could not be found.

Add-on bug

You need version 0.911.
To make the story short, there is a bug in addons.mozilla.org (https://bugzilla.mozilla.org/show_bug.cgi?id=689733)
that detect that the version is compatible with FF7.0 automatically. But it is not.
0.911 is submitted for review since last week.

Solution in the meanwhile: get the version 0.911 here: http://users.skynet.be/mgueury/mozilla/download_090.html

Rated 5 out of 5 stars

Is there any chance to make this work with FF 6.0.x on 64 bit Linux? Then I will give five stars for this addon, because it was great... but now it is useless for me.

(Update: Sorry about if you think my review was unfair, Marc, but i don't know nothing about what is going on with Firefox XPCOM compatibility - actually I don't know nothing about XPCOM neither -, but because of I can't register to your htmlpedia.org forum, I've had to ask it here. By the way, the linked version is not working for me, I've tried that.)

(Update 2: Jaure's version now works on 64 bit Linux:

Unfair review

It is here http://www.htmlpedia.org/phpBB/viewtopic.php?f=11&t=992&hilit=

As the author, this quite unfair. Linux 32 and 64 versions were never available from this site for such reasons. Now, if Firefox decided to drop XPCOM compatibility each new version, each 6 weeks, it is not my choice. It is impossible to follow as a free work for a person like me with family.

Great addon! I've been using it few years :-) I really need new version for Firefox 6 Mac OS X. Where and when can I get it?

Very nice add-ons which allow to quickly validate a web page without any hassle or even clicking! However it is not compatible with Firefox 6 and upgrade seems a bit slow, especially for Linux.
