I've used and recommended this addon for many years. Unfortunately the new 2.0 version of the Web Developer addon has lost all of the functionality that made it relevant for me:

- quick access to the proxy settings
- control over the browser cache
- ability to disable javascript entirely
- controls for changing the useragent

I'm guessing it's just not possible to support that sort of functionality inside the new webextension addon framework. Hopefully some other tool that fills these needs will become available.

Thanks for all your efforts over the years building this excellent tool.

Con gran pesar veo como una de las mejores extensiones para firefox de todos los tiempos se ha transformado en una parodia de sí misma.
Cuando en Firefox llegan a la conclusión de que el 40% de los usuarios no usa extensiones, seguramente no han tenido en cuenta el gran uso que se les da a móviles y tabletas.
Además los que formamos parte de ese 60% creo que nos merecemos algo más.
Espero que el desarrollador pueda solventar las restricciones y pronto podamos ver un add-on como en sus viejos tiempos.

With great regret I see how one of the best extensions to firefox of all time has become a parody of itself.
When in Firefox they reach the conclusion that 40% of users do not use extensions, surely they have not taken into account the great use that is given to mobile phones and tablets. Besides, those of us who are part of that 60% believe that we deserve something more. I hope the developer can solve the restrictions and soon we can see an add-on like in his old days.

Keep Up the Good Job.

With this version of the WebDeveloper you need many more clicks to get to the desired options. I want a full bar like in version 1.2.
The current version is designed to be childish.

WARNING: The new version kill's my bar who i have searchfield, https, adblock and other symbols. (Firefox ESR 52.4. - 52.5) I Use the Classic Shell addon.

I've now moved back to the older version, which I like version 1.2

Thanks for your job and the uptade with firerox quantum

I miss the special toolbar. Version 2 only has only this small dropdown menu which needs more mouse clicks. With the old permanent toolbar I would give 5 stars.

I understand the old one will not work under the new version. That's not nice but you can't help it.

I found the little block in the top right of firefox. I will need to find out how it works. Perhaps itś possibe to show what every part is when hovering over it?

Hi there!

I'm a web developer. been doing this for 20 years now. your plugin has made my work much easier.

Just updated to Quantum to realize my developer toolbar has disappeared. I'm looking around to find a way to get it back. Is there one?

Thanks for your time and keep up the good work!

Does clicking Miscellaneous | Clear History
give me a dialogue that lets me clear just the disk cache?

I want to keep my history but still empty the cache - as was possible pre-WebExt.
Empty Cache Button
https://addons.mozilla.org/en-US/firefox/addon/empty-cache-button/
lets me do that.

Bonjour,

J'utilise ce plugin depuis des années et il absolument INDISPENSABLE pour travailler.

Mais quelle idée à Firefox de ne plus le rendre compatible !! j’espère que cela va se régler rapidement.

1 stars pour Firefox et 5 stars pour vous et le module quand il fonctionnera à nouveau

Such a shame that Firefox have royally screwed this up.

I just updated Firefox, to my dismay discovered what they did to this amazing Add-on.

The five stars are all for Chris for developing this amazing tool and supporting it over the years. The newest version of Firefox (57) has absolutely neutered this extension. My response goes a little beyond just being sad. I'm actually feeling more than a little shock right now. I'm a professional web developer, and have been for well over a decade now. I've used the Web Developer plugin pretty much continually for as long as I remember. I've shown dozens of people this amazing tool; I've evangelized it all over the place. It truly is a cornerstone of my work and my career, I rely on it every bit as much as I do Illustrator, Photoshop or my IDE.

The new version of Firefox has clearly hobbled this add-on. It's upsetting because I've suffered with Firefox and its infuriating memory hole bugs through the years exclusively because of this amazing plugin. This could finally be the end of my time as a Firefox user. Can I live without this Add-on? Sure, but it undoubtedly makes the design implementation phase of my work much, much more difficult. The built-in developer tools (the likewise neutered Firebug) simply don't cut it, not for writing and editing style sheets.

Chris, I'm not sure how I can thank you enough for building and giving away this amazing tool. I hope the Firefox folks will correct their mistake in the very near future. I genuinely feel a little sick over this, time for a tall glass of wine.

Not liking the new update. Want to be able to pin the tools open for easy access. Could also quickly access items by using keyboard combinations. I hope this is temporary and can be fixed.

oh no where is gone old features? I am very disappointed with new version. I am happy for old version that was best.

Hey guys! I have been using this add on for long time. I recently updated to Quantum and the "view generated source" option seems to have disappeared. Using Windows 10 home, 64 bit, with Firefox 57.

As a front-end developer, this tool is irreplaceable. A couple features that are no longer available, and I very much miss are the pin-able settings and "disable javascript".

Great add-on, my constant companion for years. But with the latest Firefox changes, 2 of its most useful (to me) features - CSS > Display Style Information and Information > View document size - are gone. Workaround! What I did was: a) Downloaded and installed Waterfox (I have v.55), then (b) installed in Waterfox an older version of Webdeveloper from the URL Chris gave: https://addons.mozilla.org/en-US/firefox/addon/web-developer/versions/ I got Version 1.2.13. (c) Make sure you set Waterfox updates to "let you choose whether to install them" and set the webdeveloper add-on to "Automatic updates: off", otherwise you might launch Waterfox one day and find you've got webdeveloper 2. Adding an add-on to Waterfox is the same as for Firefox - you'll get a message saying "add to Firefox", but if you're doing it from Waterfox, it adds it to Waterfox. All of this is just to keep "the old webdeveloper" working, cannot vouch for it being safe.

Oh and... be careful. Waterfox just advised me to update to the new "responsive design" module (or whatever), which I did. And webdeveloper lost half of its tricks. Will have to restore the system, I guess.

בינתיים עובד ניפלא...

i just installed some new firefox (unwanted and unasked) version 56 it is now, and for some reason the "web developer toolbar" is no longer a toolbar, but an icon that holds a million subicons. i HATE that. how can i get the "web developer toolbar" to be a TOOLBAR again?

UPDATE: i changed my rating to 3 stars. i understand its not your fault, but still, this addon is useless to me this way. i would have appreciated it more, if it were a number of separate icons, that i can arrange in my toolbar to "recreate" the original toolbar. perhaps that is something you want to consider...

somehow, firefox manages to get crappier with every new version. whenever i update this PieceASheet, all my plugins stop working and the whole thing falls apart. great work, firefoxers.

This new version is totally useless for me. I need the tool "Display style information" back. Also this change made the whole Firefox totally useless for me. Where I could download the old version of the developer toolbar and old version of Firefox. This is really important and freezes all my work. Used to be 5 star extension, now 1 star. All I can do is star a uninstall process of Firefox browsers from all our school computers and searching a new tool. Sad end for such a great browser.

I know the "disable javascript" Tab has gone, but I need to put the javascript on. All slideshows and dropdown menus are no more working since update to Firefox Quantum.
How I can remove the web developer tool complete with all settings and restore the basic settings again.

Used to be able to move the tools around. Now, with the current version (2.0.1) we're stuck with them in specific locations and it makes it nearly impossible for me to use this addon with my job.
