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:

Doesn't work anymore in Firefox 29.0.
Before it was a 5 star add-on.
The Addon Bar
I recommend installing "The Addon Bar" extension to restore the addon bar to Firefox 29. Every extension that uses it has been affected by the changes introduced in Firefox 29.

@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.

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.
Needs viewport resizing, too. Rated 4 out of 5 stars
It would be useful to have a checkbox next to each setting to indicate whether the dimensions are for the whole browser window or just the content area.
That way, I wouldn't have to go into the Web Console, query outerHeight - innerHeight + desiredInnerHeight (and the same for width, if on Windows).
I was developing a kiosk app that will show full-screen on a 1920x1080 monitor, so I wanted a content window of exactly that size, so that I could see how it will look.
It would also be useful to be able to assign key-chords to the settings. That would speed up testing: make a change, reload the page, and cycle through your target sizes by hitting the appropriate keys

Very useful to maintain firefox window size
good tool for devs and testers Rated 4 out of 5 stars
This tool provides great way to see what a site looks like when the user has a given size of screen and the browser configured a given way (e.g. number of toolbars and such nonsense)
Things I'd like to see added.
1) better list of standard defaults based on what is in common use including sizes of common tablets in portrait and landscape
2) option of a 'label' on a resolution, helpful to remind you why you care.. Display in the list when choosing, but not once chosen.
e.g. a portion of the default list might look like this
768 x 1024 ipad -portrait
768 x 1366 surface -portrait
800 x 1232 xoom -portrait
1024 x 768 ipad -landscape
1280 x 752 xoom -landscape
1366 x 768 surface -landscape
Good simple addon Rated 4 out of 5 stars
This is a good functional addon. I'd like to see an option to save the size of common web pages to avoid having to set them again each time the browser is reloaded. Otherwise, thank you for this and I hope future versions will have more functionality.
Not for responsive design Rated 5 out of 5 stars
EDIT after discussion with the developer :
This tool is set up to measure the size of the entire screen (and does it perfectly), but not for the size of the viewport, as needed for responsive designe development. Please take this in account and use Mozilla developer tool for responsive development preferably.
Five stars for developer help and quick answers !
OLD review : Doesn't work perfectly, adds some extra width due to the scroll bar. Anyway Firefox now has a responsive design option in its developer tools...EDIT (reply to dev answer) : in W7 - Firefox V18.0.2, when you compare the developer view (CTRL-SHIFT-M) width value and the firesizer width value: you should get very different pixel width values... I can PM you more info or help to debug if you wish.
I would be glad to address whatever you think "doesn't work perfectly". I have not had any other reports of issues with this extension.
Does the job but it adds a blank Bar above the Add-on Bar Rated 4 out of 5 stars
This addon does the job pretty well but I have one issue with it.
When I start Firefox I get a blank Bar above the Add-on Bar which drive me crazy so I have to hide then show the Add-on Bar again to get raid of this annoying blank Bar. This has been for months and I thought it was a Firefox bug that will get fixed eventually but it didn't so I decided to make sure it has nothing to do with any of my installed addons. I started disabling every addon I installed then restart Firefox until this annoying blank Bar stopped showing .. that was after I disabled Firesizer. I actually did several tests before I write this review to make sure it's the reason for that.
I'm happy to give Firesizer five-stars rating once this issue has been resolved because the addon itself really does its job.
Thanks and looking forward to your reply.
UI suggestion Rated 4 out of 5 stars
Very usefull addon, though I would like it to be a button which could be placed anywhere, rather than a text in a fixed position on the bottom-right corner.
Rated 4 out of 5 stars
Thank you for a good add-on. I wish I could move it out of the Add-on toolbar, which I never use. Also, I wish I could name the sizes to more easily identify them. Still worth keeping.
Only does 1/2 the job Rated 3 out of 5 stars
Being able to resize to some saved sizes is only part of the solution. Must be able to save the positions, also... or at least provide a way to say "move window to NE, or NW, or SE, or SW... Please provide me with the code so that I can write my own add-on. Of course I only need this because they BROKE the functionality of re-sizing and re-positioning inside bookmarks (by providing the MALFUNCTIONING FUNCTIONALITY of "allowing only OK'd sites to do so" (meaning, "allowing no sites to do so no matter which way you check the "option").
Good, but width too high Rated 4 out of 5 stars
I like this add-on a lot. It's good for testing how web pages look at various resolutions.
However, I feel there's a small bug (version 1.7). With Firefox maximized, it reports the resolution in the corner at "1456x856"; this is odd, because the label on my monitor says that it has a 1440 x 900 resolution. In my Nvidia Control Panel applet, that, too, confirms that I have my resolution set at "1440 x 900 (native)." I am using a two-line permanent taskbar (Windows Vista), so I lose height pixels, but I'm puzzled how the reported width can be greater than 1440.
EDIT: After reading orev's response, below, I am now more educated, and sort of retract this bug comment... or more appropriately, perhaps I should assign it to Windows. (I'm using Vista Home Premium, SP2, by the way.)
The essence of this "bug" lies within Windows itself. When you have the browser window in "window" mode (not full screen), the height and width are calculated (by Windows) including the application area itself, and also the borders around the application. Windows 7 uses somewhat thick borders to create the appearance of glass windows. Other versions of Windows use different sizes, and it's also different on Mac and Linux.
When you maximize the window, Windows plays a trick by making the application big enough so you can't see the borders, but they are still there; off the edge of the screen. Firesizer has no way to know this, and the width of the border can be different on every system, so there is no way to simply fudge the numbers if you are in full screen mode.
