Gmail says my browser is unsupported but yet Google just updated it and all my extensions are disabled. Whats up? Driving me nuts.


I am getting the followinf when going into Gmail

Some important features may not work in this version of your browser, so you have been redirected to the Basic HTML version. Upgrade to a modern browser, such as Google Chrome.

When I go to upgrade to a modern browser it tells me:

If you're using a supported browser,''''(which I am) ''''but see a message in Gmail that your browser is unsupported, you may be using an extension that interferes with browser detection. Try disabling your browser extensions to resolve the problem.

All my extensions are disabled. and I want to use firefox gmail and see all my features. What gives?

You are actually using a very old version of Firefox (3.5.8). Please go to www.getfirefox.com, and download and install the newest version.

Question owner
