  • Easy and works!
  • This is exactly what I need. Small and simple. My only wish would be for a whitelist feature.
  • This add-on has potential, but the fact that I cannot move the buttons to anywhere I like turned me off on this add-on, allowing the ability to move the buttons or remove them individually and this add-on would be perfect in my opinion.

    Armed with this new info (thank you Dev!!) this add-on gets 5 stars!!
    You can customize your toolbar and put any of the icons anywhere you want (google for help on this if needed). The icons in the 'add-on' bar are depreciated (since the add-on bar has been depreciated by Mozilla) but remain there for the users who want to use it still. You can turn off all of the add-on bar icons by hiding them (in the options, right click any icon to get to options) and then just use the customize feature in firefox.
  • La extención siempre fue muy buena pero en estas horrendas nuevas versiones de Firefox no funciona adecuadamante.
    Espero que actualicen esta extención ... y a los de Firefox ¿De donde sacan que parecerse a Chrome es bueno?
  • At the moment I use 21 Firefox add-ons. If I were allowed to keep only one, it would be QuickJava. It blocks so many annoying things, it allows you to pick and choose what to block and what to allow, and it does all the above with a minimum of fuss.
  • Still works nicely with Awstralis, I'm relieved to say.
    One of the essentials.
    Much praise and Thank you.

    I have put the [JS] button on the nav bar (for emergencies!), and the [QJ] button in the new C̶r̶o̶m̶e̶ FF tweak panel.

    That nav bar is going to fill up very quickly with status indicators!! I hope all indicator icons I use there will soon have a 'microscopic' option. (It seems to be a mozilly decision to insist on biggish icons.)

    One small usability gripe is that one can only change one option at a time in the [QJ]v drop-down; I change any one setting and FF bounces me out again, so I have to dig my way back down to change the next.
    I suspect this too is more a FF usability imposition than anything else (?).

    Even more confusing is that if I click the [QJ] itself, it toggles all settings but one never sees the change (because again, FF immediately bounces me out) - I would have to dig down again into FF tweaks if I wanted to check the status, but I guess I trust it by now (probably a bad decision...).

    Also, it isn't explicit that right-click on the [QJ] will bring one to the hidden QJ option panel, something one finds by guesswork. For new users it might be advantageous to have an explicit "options" choice in the drop-down. It's moot.

    btw, what does "reload on change" mean?
    Am I being dense or have I missed some documentation somewhere? (Reload what to what on change of what?)

    One further question - when I toggle JS (or J) to 'off', does it actually stop/kill the relevant background processes, or does the setting apply only to new instances?
    My preference would be for killing off rogues in the backbround.
    Typically the review section shouldn't be used for asking questions, in the future please use the support site, github issues tracking and/or Contact Me option on the support site.

    1) Yes, FF limits the types of buttons you can use and the dropdown automatically closes. When you click the QJ icon it should change colors to indicate the status of ALL of the items, the only time it doesn't do this is if not all of the items are the same status in which case it indicates On with a "!" next to it.

    You could try using the custom style piece to remove padding and change the font size smaller to get smaller buttons.

    The extension description clearly states in the Usage section that right clicking any visible QJ icon will display an ability to get into the options. There is also a menu for "Help and FAQ" and the main support site which answers some of your other questions (such as "reload on change"). Some settings apply immediately (such as CSS and I believe J,F & SL), while others apply to the next page load (such as JS, Images), these are controlled by the browser (JS used to be immediate) which is why I give you the option to reload the page on a change.
  • An amazing and very useful add-on, but Firefox 29 broke it.
    In addition to removing the add-on bar, forcing QuickJava to clutter the single control bar instead of sitting unobstructingly in its rightful place, it also made it not work at all:
    All options now appear disabled all the time, and won't change when clicked.

    "Refresh icons" doesn't work.

    Edit: Enabling/disabling images does seem to work when one refreshes the page, though there is no feedback at all on the icon itself. It never updates, not even with "Refresh icons", and that applies both to the toolbar and to the horrendous new Firefox menu.

    Edit2: And now after rebooting Firefox, it appears to work.
    Strange, I've been using it in FF29 for weeks now without issues and other users have also been using it. I'm not sure what fixed it but at least it is working for you now. Please note that the review section is not valid for bug reports, please use the github repository from the website for issues reporting/tracking.

    I'm sure some of us know about the JS fail suddenly across Gecko engines. Well this plugin works to re-enable JavaScript if need be including CID. Of course, this was a last ditch effort to secure my knowledge and moved on (back) to CD (Webkit.) It was a nice 2.5 - 3 decades Mozilla. Farewell.

    Thank you.
  • i have found out that quick java does not stop already working javascripts any more. that is bad, but quickjava is still good addon, for that i set 5 stars.
  • Thank you for this amazing extension – it can help in making browsing faster, solving compatibility issues, and maintaining privacy!

    I'd have just one request: could you make QuickJava addon icon movable, or the option to have it on the navigation and menu bars?

    Thank you!
    This functionality already exists, you can even add other icons that are directly for JavaScript, Flash, Java, ect. Please google "Customize firefox toolbar" to find step by step instructions.
  • A must have - brilliantly simple and easy to use, this is the first thing I add in any new Firefox install.
  • This is addon is very useful because it allows to enable or disable plugins and settings with a mouse click.
  • Instantly optimizes my webpages. Especially the chunky ones, full with flash animations
  • This add-on is brilliant! Saves me lots of money every month. My choices for internet are dial-up, satellite or mobile; no cable, no DSL. This add-on cuts my bandwidth to less than half every month. The only problem with this add-on is it's name; should be called Bandwidth Reducer or something more descriptive. Absolutely love this add-on so much, I'm making a contribution. Thanks Doug G.
    Thanks for the kind review. While some users appreciate the ability to easily reduce their bandwidth, most users appreciate the security benefits. I will note it in the item description which should help it show up in searches though :)
  • Being able to click JavaScript on and off is great. The presentation by the author is also great. No hocus-pocus - it's right in front of your face.
  • Ottimo add-on per un controllo completo del proprio browser, magari all'utente entry level sembrerà inutile, ma molte features sono sicuramente vincenti
    - andrea valori
  • Even though Mozilla doesn't want you to, you may occasionally need to disable Javascript, Java or similar features on webpages either for testing or maybe since a page is using the features in an abusive way. QuickJava is a very simple and simple to use addon to do exactly that without fiddling with about:config options directly. It even supports disabling animated images, that is a feature I didn't use ever since I stopped using Proxomitron :-)
  • If your a developer your better off with WebDeveloper Tool Bar as it offers more features
    There are times I need the items offered in Web Developer Toolbar, but usually it's turned off to save the space of an entire toolbar. In any case, to each their own, the extensibility of FireFox is part of what makes it so great.
  • This addon went from good to great with the 2.0.2 update. I got rid of a toggling proxy addon since there is a toggle proxy button. Now if I could whitelist a site with the Flash part of it I would get rid of another addon.
    Glad you love the addon. FYI the Proxy button has been available since Version 1.7.3 Released May 16, 2011 ;)
  • A great add-on, especially since Mozilla has decided to cater to a few noobs by removing the Javascript on/off option in Tools.

    Hopefully it will continue to work on future versions of Firefox.
  • Thanks for the update! Could you also consider adding a button for enabling/disabling "work offline"? It'd be very handy. Thanks
  • I didn't expect to see this updated for FFox 23 and wasn't looking forward to searching for an alternative. Thanks David, for the update!.

    Edit: Ooops. This update brought to you by the letter D. Thanks Doug! :)
    David provided some of the visual changes, all functionality changes were done by myself. :)
  • love it, great addon, but was really irritated did not work with FF23, and i made it check for update but nothing would work. but after i came to the addons.mozilla page and had to manually download to update. thought i would tell you.back to the rating. its great when multiple tabs are open i can just click the little FLASH (usually) button to kill all flash to speed up and free CPU. thank you for such a great addon.quickjava and adblock plus are a must have whenever i reinstall firefox.

    edit: looked below at a suggestion, ads are bound to migrate to html5 video soon as well. i agree would be great if we could disable that.
    I have looked into how to handle HTML5 elements and how to provide a proper GUI. Unlike any of the other buttons, disabling HTML5 will require changing multiple options. (Go to "about:config" in your url and put "media.*.enabled" in the filter to see a list, most of which would need to be modified) This is on the "being considered" list for now but may not make it into the next major version which I am currently working on/testing.
  • Great addon but it's not working correctly in Firefox 23 (at least for Flash) because Plugins page and permissions have been changed by Mozilla.
    A new version has already been submitted and is waiting approval from the Firefox team. You can see the support site for more information.
  • This extension is extremely useful for anyone looking to get rid of all the cruft from their web browsing experience.

    Bravo to the author!
