Firefox is still disappointing

I have been working on Firefox, fixed some things, see recent posts:

I was considering bringing back FF as the builtin browser; however, still cannot get rid of the flicker on my Lenovo desktop PC. The content of the window flickers periodically. When this flicker occurs, it will break a text-input box if it has keyboard focus, and will wreak the menu.

What I mean by the latter, is if you click on the menu button, the three horizontal bars on the top-right of the window, then wait until the next flicker. Then the drop-down menu will disappear, and the menu button becomes greyed-out and unusable, see this photo:

I reported this to the forum:

The flickering window in FF has been around for awhile, and there are many suggestions to fix it, for example:

1. Turn off hardware acceleration
2. Turn on hardware acceleration
3. Turn off smooth scrolling
4. Flickering happens only when 4+ tabs open
5. Use Xorg modesetting driver instead of intel
6. Disable gfx.webrender
   

None of these fix the problem on my computer.

In short, FF is disappointing, and it looks like I will stay with Chromium as the builtin browser.
