Does this Firefox plug-in exist?
 

Sometimes I will go to a site and the site will force my browser to a specific height and width, which drives me crazy. Then afterwards I need to mess around and try to get my browser back to the appropriate settings that I like. Which isn't as easy as one would think. Is there a plug-in or another easy method of resizing my browser window to the exact sizes that I like? I could also see this being beneficial for testing how websites look.

Options / Content / Advanced / Allow scripts to move or resize existing windows

Do you have that option checked?

not that i know of, but im not a huge firefox fanatic

Not anymore, thanks!

Yes, web developer toolbar https://addons.mozilla.org/en-US/firefox/addon/60

never had that problem, but I unchecked the option that Jarmusch posted just in case

Thanks for posting this, Sly. I have that issue from time to time. Thanks for the fix, guys.

Sly, you rock, I hate that shit and was thinking of developing my own plugin since I never seen one, but that tip from Jarmusch saved me time.

Also, if you guys don't have "Web Developer" installed, I'd suggest it. Even for just doing html pages, ti's a huge help... one of the features, for example, is a "resize window" option where you can tell it width and height and it resizes the window to it.

So you can check your designs in various sizes, or... should something sneak through and resize your browser somehow again, it's a quick button press to get it back to the way you like it.
