Prevent websites from resizing Firefox’s browser window

with 17 comments

Firefox is my browser of choice. Although we happen to have a rather large number of Opera followers at the TS forums, I have been left unconvinced and kept faithful to Firefox ever since version 1.5 came out. At that point the browser was more secure than ever, rock solid, very polished and popular enough that you had dozens of extensions to customize it to your liking. I haven’t looked back ever since.

Now, one of the most obvious tweaks you can apply to your Firefox installation is removing the annoyance of letting websites resize the browser window at their will. Despite of the more sophisticated pop-up blocker that comes in most recent versions of the browser, many websites still do away with popping those up and in many cases resizing either your main window or maximizing the pop-up window to get your full attention (just before you hit the X button).

You won’t even need an add-on to do this.

  1. Go to Tools > Options
  2. Click on the Content tab
  3. Next to where it says “Enable Javascript”, click on Advanced
  4. Uncheck the option “Move or resize existing windows”

You’re done! I will try to bring more of these basic, and other not so basic tips on a regular basis to the blog.

Also remember we have a complete Firefox tweak guide posted in the main site.

  5. Thanks for the tip, I should really spend more time looking through the menus for things like this. I hate when websites change my browser size without asking! Of course it would be stellar if site builders just wrote better code with fluid designs that scale nicely to any size.

  7. Doesn’t work. Some websites (possibly runescape) still frequently mess with my window size.

  8. I love open threads! It lets me say that this answer was awesome. Here I was on tmobile’s site trying to figure out how to upload pictures from my phone to the internet and this tutorial decided to resize me.

    Never again!

    Thank you for this great tip. It’s funny how something as simple as having a webpage resize my browser be so annoying, but it really bugged me.
    I’ll be looking forward to this page in future for similar tips and hints

  10. I’ve got Firefox 3.5 for Mac, and it works the same way, but the menu is found under Firefox->Preferences->Content, and then click on ‘Advanced’ near where it says JavaScript &c as above.

  12. Thank you for this! Developers, write better code so that your applications scale nicely. Web apps have no business interrupting users’ workflow. I don’t think anyone out there really appreciates this.

  15. Thanks for the tip! I was checking out Hybrid’s site (the music group), and it resized my browser without asking. So I re-sized it back to the way I like, and then clicked on the “Created by ” link at the bottom, to send the designer a nasty email, and HIS website also resized my browser! Argh!

  17. This tip helped me too. All of a sudden my browser opens maximized, which it never did previously, and the maximize button only minimizes to the Task Bar. The only way to display the window, I had to Right-Click and select maximize. Clicking on the Task Bar icon did nothing, but flash the screen. Anyway, I followed this tip, then closed the FF window, restarted FF, which was still maximized, clicked on the minimize/maximize button and what do you know, the screen returns to my preferred size! Thanks a Million!!!
