When I tried to open Google+, it said it's no longer supported. Internet Explorer and Chrome do not have these issues.
Solved! Go to Solution.
hello, this is a google issue. on their support site they say that all current versions of firefox are supported but apparently something has gone wrong in there browser sniffing which will have to be corrected on their server side...
Hello Firefoxhelper123, confirm philipp's above reply, see also :
My apologies to the question owner and others. This response does not solve the immediate problem and won't help but having wasted several hours trying to figure out what was going on and suspecting a ploy to direct me away from Firefox and use Google Chrome instead, I am not feeling particularly charitable.
I have therefore uninstalled Google Chrome and other things Google. In Google's uninstalling questionnaires I made it clear that it was because their search engine was no longer not compatible with Firefox.
I know I am cutting my nose of to spite my face but that serves me right for becoming too dependent on Google's search engine.
Perhaps if more people uninstall Google Chrome and say why, Google may be prompted to do something about the problem more quickly!
