Can't do online gaming Rated 1 out of 5 stars

I play on GTArcade and it needs Flash in order to work. I use other browsers to play, but it won't work on Firefox. I tried the add-on and still didn't work. I know the site works with other browsers but it is just not working with Firefox.

Quality change needs fix Rated 3 out of 5 stars

It can't change flash quality. Please fix it.

Is it possible to remove F12 hotkey? Rated 5 out of 5 stars

F12 conflicted with firebug and standard dev. tool hotkey.

This is very uncomfortable.

An End to My Flash Frustrations Rated 5 out of 5 stars

Are you Kidding?! How could it be any easier...

I am not a gamer. However, I do live on the Florida gulf coast where Hurricane season flash weather map viewing is a common pastime and almost a must.
My favorite alert site went from free to pay... Grrrrr! That left visitors with a 1/6 page live sample frame. One click of the "G" (or F12) gave me back a full browser view and uncovered the lost overlay controls. WOW!
I went to some alternative sites and found this simple, straight forward add-on (along with the F11 key) opened up a whole new "world" of full screen flash animation viewing.
I'm using Firefox 12 and it works without a hitch.
Thanks A-) for a great little utility that helps keep the Firefox web viewing experience way ahead of the rest.

You are very welcome ;)

Glad to hear it works well for you. Nice of you to let me and everyone else know about it - Makes a nice change from all those "doesn't work for me" reviews. Thanks ;)

Hotkey problem Rated 4 out of 5 stars

Firebug's hotkey and hotkey of this are same. Firebug does not open by F12 if It is installed

Please consider relicensing Rated 4 out of 5 stars

Excellent contribution.
Please consider relicensing to APL/MPL/LGPL like open source.
I think it would make more users comfortable about its use.

Thanks, but why relicense?

Hi Ganapathi,

Thank You for the stars.

Why would anyone (excluding the deranged and the feebleminded) be "comforted" by MORE legalese mumbo-jumbo, rather than less; I'm certainly NOT..?!?

My extension is free, with no strings attached what so ever; heck, you can even use my code and graphics with impunity. What's to be "uncomfortable" about..?!?

I only used it at one flash game that I liked and there it worked great. There should be a possibility to give the symbol into the context menu (of flash content) or to an other bar, Because I use it that rare, so the symbol wastes the appbar space.

A great idea, but...

... I'm afraid I haven't the time or money to spend on such an upgrade. I did in fact plan something along these lines (an option to insert a button next to any zoomable Flash content on the page), but since this would be quite a lot of work, and since this extension isn't exactly making me rich ($27 donated so far, despite 50K users over four years), I'm afraid it isn't likely to get done anytime soon (unless I win the lottery or some such).

Tried on a few flash games on facebook, regretfully it fails to work correctly on the majority. To bad, nice idea, though.

Very useful tool but with flash multiplayer on line games doesn't work.

Rated 5 out of 5 stars

I love this add-on. It does what it say it does.

Rated 4 out of 5 stars

Nice add-on, but should have an option to keep default background. If I choose any color, even transparent, some background colors in the game get overrided by the color I've chosen, even if it isn't forced.

Until this is fixed, 4 stars only. Otherwise would be a great add-on.

Flash Game Maximizer Rated 5 out of 5 stars

Flash Game Maximizer is quite the tool!
Go to
on this website you will find a 26 gigapixel flash image of Dresden, Germany
after the image of Dresden loads, click on the Flash Game Maximizer Icon,
wait for it to load, just remember use the (A) on your keyboard to zoom in
and use (z) on your keyboard to zoom out, and the right-left-up-down arrows on your
keyboard to zoom around
Enjoy zooming in and around!

Works perfectly, thank you!

I have dual monitors and I like to watch football (via flash based video) on one screen maximized, and use the other monitor to surf the web or play a game.
Prior to your addon I could not watch football fully maximized because as soon as I clicked on the other monitor the video would minimize. Now however, it works flawlessly!

Again, thank you!

Glad you like it

Hi netfool,

I'm glad to hear that my extension can be used for your purposes, even if it was not quite what it was intended for. I will make a note of this, and try to see if I might provide even better functionality for people who wish to maximize non-game stuff, such as video-players and the like. I might even release a separate extension for this purpose at some point in the future...

Please read the "important note"

Hi jpenguin,

Please refer to the "important note to all users" on the main page, for an explanation of (and two ways to fix) the "no flash detected" issue (you can either download version 1.3.6 or start using the toolbar-button to make the button(s) work as intended).

With regard to the compatibility issue: Unfortunately I was given the impression that FGM 1.3.0 didn't work on Darvin (Mac OS-X) platforms, prior to uploading it. Accordingly I set the compatibility to "Windows" only. If you want to avoid the checkCompatability::false hack, try installing version 1.3.6 (available on the "Old Versions page", even if it is in fact a newer version), which should have its compatibility set to "ALL".

First off, this is an amazing software that has no match on the web today. 1.3.5 works great for me with firefox 3.5.1. I have a request, which I hope the creator will at least read.

Could you please look into stretching the video streams ?
I use your great add-on to maximize video streams, and sometimes the video was not recorded in the right aspect ratio. Your window aspect just changes the video player size, not the stream. I think it will be really useful to allow disproportionate stretching to a defined ratio (4:3, 16:9, 5:4, 16:10) not just the window size. Another good idea is to allowing zooming, or basically fit the content based on height or width, to cut off the black bars in the video stream.

Thank you very much for all the work you put into this.

This review is for a previous version of the add-on (1.3.5). 

Changing aspect?

Hi MikeZ88,

With regard to changing the aspect of "video-streams":

Since my extension is only able to change the dimensions of the actual Flash content (in this case the "video player"), I consider it highly unlikely that this would result in a corresponding change in the dimensions, and certainly not in the aspect, of the video-stream being played. It may be, for some players, that the video-size is changed along with the player (at least I must assume so, since you probably wouldn't use FGM with video-players otherwise). However, since the aspect of a video stream is something inherent in the stream itself, it is likely to be fixed by the player-code.

If you e-mail me a link to one of the players you use, and which you know to work with FGM, I will try and see if anything happens to the video, if I make my code maximize the player using a different aspect-ratio. In the unlikely case that it works, I will of course make sure to include some kind of "aspect modification" feature in the next version (at some point I may add some kind of "manual size entry" feature anyway, but unless the above gives a positive result, it won't be very high on my list of priorities)...

Greatly Improved from earlier version. F12 shortcut
works well. You can hide the statusbar button in options. I like it on 3D Golf:

Wont work Rated 5 out of 5 stars

doesn't work on for me, which is where i play all my games :(
However, i really like the idea for this add-on - if you could make it work on more websites, it would be amazing ;) 3 stars.

EDIT: Thanks for the reply. I've not retried the add-on, and it works very well. 5 star rating!

(Occasionally it will put it into full screen, and the game will stay the same size, but thats thought the games code, no the add-on.)

I'm also very pleased that you took the time to reply to me, AND to research why it wasn't working :). There should be more people like you on the internet. Thanks. :)

I'm afraid it is Kongregate that "doesn't work"

Dear Ziaix,

Not only does Kongregate use script-injection, making it nearly impossible to reliably parse their HTML documents for Flash content, but they even make sure to obfuscate the actual names of their Flash files, using a server-side script to look them up from a number.

[You can try it yourself i you want: Go to one of their game-pages, right-click the page and choose "View Source", then search for any file-names ending with ".swf"... Normally one of these would be the game itself, and to maximize it "manually" all you would need to do, would be to paste the filename into the location-bar (combining it with the URL already there to make the filename absolute) and hit enter - However, at Kongregate you won't find any such file-name to paste...]

Now, I don't know what would prompt Kongregate to do all this, but the end-result is that not only will FGM 1.3.0 not work with any of their games, but it is highly unlikely that FGM will EVER work on their site (unless you can tell me how to write code that will correctly "guess" a file-name, given an integer number?!?)

I must say that, unless you have had a very different experience from what I've had during testing of version 1.3.0, I resent the implication that "FGM doesn't work with a lot of sites" (ie. you say I should "make it work on more sites", implying that you have found a large number of sites where FGM doesn't work).

I've done a lot of work (1200+ lines of code by now!) to make FGM work with as many sites as possible. Unless you are experiencing some issue that I'm not aware of, it really should be only a small fraction of games/sites that won't allow FGM to properly maximize their content, and in most of these cases the reason will be along the lines of what I describe above (which is to say: Nothing I can do anything about).

Having said that, it IS my goal to "make [FGM] work with more websites", only I really don't see how it could ever be made to work with Kongregate? However, if I, or someone else, find a way to do so, you can be sure that I would make sure to release a new version of FGM as soon as possible...

In the meantime, I strongly suggest that you play your Flash games elsewhere - Then you would also be free of that ugly chat-thingie they use on Kongregate, which would only prevent you from properly maximizing the game anyway (AND distract you from attaining that elusive high-score...)

... OR, If you REALLY like Kongregate and don't want to play anywhere else: You could try contacting them and ask them to use proper EMBED and/or OBJECT elements, rather than using script-injection and file-name obfuscation.
