As I read the post by MrAlex94, I noticed a remark that the browser Chrome is good as a user agent. To me, that's terrific! Looks like I'll have to consider Chrome again.`

Here are what I find as reasons to scream about Mozilla:

Popups:

(a) Several times a day, my attention and concentration get interrupted by, for me, the unwelcome announcement that there is a new version I can download. A new version can have changes I don't like and genuine bugs. Sure, I could keep a copy of my favorite version from history, but that is system management mud wrestling and interruption of my work.

(b) Now I get told several times a day that my computer and cell phone can share access to a Web page. In this action Mozilla covers up what that page was showing I wanted it to show. No thanks. When I'm at my computer, AMD 8 core processor, all my files and software tools, and 1 Gbps optical fiber connection to the Internet and looking at a Web page, I want nothing to do with a cell phone's presentation of a, that, Web page.

(c) Some URLs are a dozen lines long and Mozilla finds ways to present such URLs with all their lines and pursue clearly their main objective -- cover up the desired content.

Mozilla needs to make their covering up, changing, the screen optional or just eliminated.

Want me to donate? You've mentioned as little as $10. Deal: Raise the $10 by a factor of 5 AND quit covering up my content and interrupting my work, and we've got a deal.
