I always thought that besides the location of the profile folder and the launcher as well as some different default settings, Firefox Portable is the same as the non-portable version of Firefox.
Can you tell me whether there are any other significant differences?
I ask this because I am having a problem with an extension. I don't get a drop-down list in this extension where I am supposed to get one. But with the non-portable version of Firefox it does work. So, I wonder what difference could be responsible for this problem.
You already asked this question just 16 hours ago. Someone will get to it eventually. But it's less likely if you post the same question more than once... thus, cluttering the forums... thus, making it more difficult for the folks here to voluntarily support you.
Sometimes, the impossible can become possible, if you're awesome!
