Web Development through Browser extension

[brian]

Currently, I am using Firefox and Firesizer. In order to check the responsive design of my site as the development is in progress. But firefox is creating many problems after the recent upgrade. And good browser extension other than Chrome is more preferred.

Any suggestions?!!

I am not a developer but Firefox doesn't create any issues apart from spacing CSS. I don't know what you are facing.

But certainly if you want an alternative then you might wanna try Edge or Safari. Although Chrome is much preferred but since you don't want it.

Check for their extensions and addons. They might not give you want you need right away. But clearly you will find it.
