Replacement for not working Firesizer Rated 1 out of 5 stars
It WAS one of my favorite Add-on's, but v1.7.1 doesn't work anymore with Firefox v55+.
You can find a similar, but still working Add-on here:
It works for me on 55.0.3 (32bit) together with Add-on "New Add-on Bar" here:
Hope it does it also 4U!
Great Tool for Consistent Window Sizes Rated 1 out of 5 stars
Thank you for maintaining this add-on for so long. Unfortunately when I was auto-upgraded to Firefox 55.0.1 (32-bit) it now reports, "this add-on is not compatible with your version of Firefox." :(
When the addon is compatible again I will raise my review to five stars.
Awesome Genius Simple Idea But Helas The Pixels Are Dead Wrong Rated 4 out of 5 stars
I disagree with the people who need the actual inner viewport pixels: for that there are a dozen other good addons!
The unique thing about THIS resizer is that it measures the actual full browser windows. YES that differs from machine to machine and height of the top section is different for any person but I prefer a realworld total measurement over a theoretical "what could have been" as that is a false sense of consistency.
Back to why I retracted a star! No its not because of the added search for and hassle to install the Addon Bar. Its because when I set the browser window on my machine* to, say 1024x768, and make a printscreen photoshop measures 1014x763 and, when the browser is fullscreen it measures 2576x1616, while I have a native resolution of 2560x1600. As you see, the pixel counts are dead wrong and if this was fixed, i would give this addon seven out of seven stars and donate!
Good luck and Keep the genius vision alive by sticking to TOTAL browser measurement and not the inner window measurements since not a single person will ever use full screen for normal websurfing.

The issue with the incorrect pixel size for a regular window is because the borders added by Windows are not included in the size, and there's no way for the extension to know how big they are. Different versions of Windows have different sizes, and you can also change the size if you want to. Windows 10 also has these borders, but Microsoft made them 100% transparent, so you don't see them but they are still part of the window size calculation. This is why the mouse cursor changes to the "resize" icon when you get close to the border of a window, even if you're not touching it yet.
Also, the fullscreen issue is the same. When Windows makes a window full screen, it really just resizes it to be a little bigger than the screen, so the borders are not visible.
Love it but no longer on toolbar Rated 5 out of 5 stars
I loved this! It gave me my optimum browser size and retained its preferred position. But it's no longer readily available because it's not listed in the customize window and thus no longer on my toolbars. I've tried everything suggested by various sites including the new add-on bar and Barlesque. I've been able to reclaim a few icons but not the ones I use most - including FireSizer. (Obviously I can still get at it through my add-ons page but that's cumbersome and inefficient.) Since this is also true of several other add-ons, I don't think it's the fault of this developer. Hence my rating. Highly recommended especially if it can be returned to the toolbars.
Great, but pls add viewport resize... Rated 4 out of 5 stars
I did read the FAQ and I do understand your reasons... However I'd like to use Firesizer for recording tutorials/making screenshots for documentation and I really only need to capture the site content in a consistent format (HD) and not the full browser window...
Otherwise simple and great add-on. Thanks.
Responsive design mode
In that case, you will probably be better served using the built-in Responsive Design mode where you can set the viewport size. It's under Tools / Web Developer, or you can press Ctrl+Shift+M.
Muito bom! Rated 5 out of 5 stars
Exatamente o que preciso, com a simplicidade que eu queria!
On Fx44--still working fine, no other add-ons required Rated 5 out of 5 stars
The add-on/statusbar stub is still there in Fx44, so a little CSS is all I need to make it visible and use it. Love it!This user has 2 previous reviews of this add-on.
INCREDIBLY handy if you need to take consistently sized screenshots across many days Rated 5 out of 5 stars
I regularly need to incorporate screenshots into documentation of Web applications. Firesizer is THE tool to set my browser to a known size so that screenshots taken across several days are all consistently sized. Excellent add-on!This user has a previous review of this add-on.
Extremely Useful Tool for Developers Rated 5 out of 5 stars
For anybody developing web sites, this is really helpful to have.
Nifty little tool - and a feature suggestion Rated 4 out of 5 stars
Thanks for creating this nifty add-ons. Knowing where and how the custom dimensions are stored would make it even a better add-on. Keep up the good work.
Ditch the add-on bar!! Rated 3 out of 5 stars
I agree with other posters that forcing us to put back in a feature (add-on bar) which has been abandoned (with lots of notice to boot) in order to support this single add on is completely backwards thinking. This used to be a daily driver but now it's simply inaccessible. PLEASE for the love of dog fix this! Allow us to place it in the new customizable menu!
Used to be favorite, but now... Rated 3 out of 5 stars
Please make this one work in FF 29+ without the need for installing the extra statusbar add-on!
Firesizer used to be my most used add-on: it's very helpful when you change browser window size often to different screen standards. It's also easy to customize.
But I'm consciously limiting the number of installed add-ons, for reasons of browser speed and stability, so really don't need an extra add-on to keep another one working. Also 'keeping alive' the status bar now that it's been structurally abandoned by FF isn't the way to go. So I've stopped using Firesizer for now.
Having a small popup panel (e.g. like Ghostery has), or having the resize options show up in the right click option menu would be great.
Not showing the correct resolution? Rated 4 out of 5 stars
Looks like a great add-on for working with responsive design... My laptop has a 1920px width and when the window is maximised it's showing 1936 x 1186? And it makes no difference if there's a scroll bar showing or not?
I have explained what you're seeing in this reply to another comment:

@blafuchs: I tried your hack but it was off by a couple pixels when testing it with my media queries. @McGWD hack is spot on. If the author fixes the original I'll give it 5 stars. With the hack though it's perfect!
Great App !!! Rated 1 out of 5 stars
[EDIT: After using this tool for a good chunk of time, I realized all the readings are off. After comparing measurements to other window measuring tools I found the measurements are WAY OFF. Tested both viewport and window size and found measurements displayed are not close to either!!! I would post picture evidence but no upload feature.]
I needed a simple app to help with responsive window resolution testing for my website. And this app fit my needs almost perfectly. It could use a few more features like starting with a few more standard sizes but otherwise great job!
If you make it open source, I promise to make some improvements from similar apps (but more advanced) that I have used and tested and found to be useful. Sadly, they only work with Chrome. =[
Oh, and a super thanks for letting me know about Barlesque, I love it!!!!
This extension is meant to resize the entire browser window to the specified size, not the HTML viewport. I really feel that most, if not all web site designs seem to target some sort of ideal viewport size (like 1024x768), and always seem to forget about window borders, scroll bars, etc..., and it really drives me nuts. You can't ignore the fact that browsers have all of these interface elements. If you're developing for mobile devices, this is a different story, and in that case, using the viewport size would make more sense.
Firesizer's measurements include these window borders, top/bottom status bars, menus, navigation buttons, etc... When these are included, the measurements are accurate. Further, when the window is maximized, Windows actually just makes the window so big that you can't see the borders, but they are still there. This will cause the measurements to appear to be inaccurate in a maximized window. There is no way to account for this in the extension because the border widths are OS specific, and users can change them if they want.
correct ViewportSize Rated 4 out of 5 stars
@McGWD: nice work, but the viewport is actually content.document.documentElement.clientWidth
document.documentElement.clientWidth in that case returns the size of the whole program window. Seems the addon is not working in the document window scope by default.
Rated 5 out of 5 stars
I made it so it shows the Viewport-Size!
Rated 5 out of 5 stars
Very simple, saves some time resizing the browser window while working and need multiple browsers open and next to each other. Would be nice if I could "nickname" the size, since I have multiple browser sizes for different projects.
Saving position would be nice Rated 4 out of 5 stars
it does work good but i wish that i can save/restore the position of my window, thanks anyway.
