Firefox-Hilfeforum

Greetings everyone,

Firefox is my preferred browser and I really prefer the Firefox Engine over Chromium that most other browsers use.

I want to install a backup browser that runs the Firefox Engine in case my Firefox browser has a problem.

I searched a lot and I thought installing this would be the best option: https://www.mozilla.org/en-US/firefox/developer/

However, I’m worried that installing the Firefox developer edition will change my Firefox installation…

( :( :(

Ok. The update downloaded 2 1/2 days ago. I've used Firefox since that download. It didn't install until now. 2 1/2 days later. Why the long delay? And why don't you have something show up in the banner or toolbar that designates that an upload to Firefox is happening? Now, we all have to guess why Firefox is behaving slow and erratic, close and re-open, and check for version.
