on responsive view inspect element option not working. so now it's vague plugin now.
Perfect thing!
I've been using the Web Developer extension for YEARS. As someone that works in the Digital Marketing industry, particularly focused on SEO, this tool time and time again has helped streamline many important tasks I have to do when evaluating websites. It's flexible, customizable, and just really makes life easier. Thank you to the dev, for years of use. I'm planning to make a small donation to the dev to express my gratitude, but I thought a review was due first. The best thing about this tool, which it seems other people have also expressed, is the fact that i can trust it. With so many extensions out there, and so much privacy intrusion and "hacking", I've become incredibly weary of what extensions or apps I install (extensions can give you viruses too), so when I see some extension or script that focuses on one thing, even if it has good reviews and a decent number of users, I'm hesitant to install anything and I start looking up the dev and his or her reputation, etc. This guy, man, I've been using this for so long, and the trust and reputation is there. This tool is a MUST HAVE for any web developers, search engine optimizers, or anyone that works closely with websites, really. 100% recommended, would give it 10 stars if I could!
absolutely beginner myself but I guess I'll be using this extension for a long time...
