Personally I find it a little annoying when websites resize my Firefox browser window, particularly when the website has a fixed width anyway! .. so I went looking for the option to stop this happening. It’s dead simple, just follow the instructions below and you too will have total control over the size of your browser window:
- Go to Tools > Options (Edit > Preferences for Mac and Linux users)
- Select the Content tab
- Untick “Move or resize existing windows”
- Click OK, then OK again.
That’s all there is to it.
I made a discovery today – I have been using two Firefox windows for a while now (so that, for example, I can have google docs open in one window on one screen, and some websites I’m browsing in another window on my other screen) and today I had a website open in one window that I wanted on the other, and I thought “hey, I wonder if you can just drag a tab from from window to another?” … and you can! You can also hold down the Ctrl key to duplicate the tab instead of moving it… and you can use the same technique to duplicate tabs in the same window. What a handy feature!
