Firefox Developer Edition downloaded 89.0b1 tonight. When you choose Submit Feedback in the help/about form it goes nowhere. Actually to a "coming soon" page for ideas.mozilla.com. Is that so you won't have to field complaints about the "improvements" in this version? Because I have several complaints.

I am using the Developer Edition of Firefox and this problems occur when I noticed that the permission pop-up didn't contain all of the information it was supposed to say. This problem also happens when I wanted to bookmark something in the browser itself.

I have installed quite a few extension and some of them also experience the same problem :

  • React Developer Tools (affected)
  • Multi-Account Containers (not affected)
  • AdBlock (not affected)
  • Password Manager (not affected)
  • Tab Session Manager (not affected)

I think this is a bug on Firefox end and I would like it to be fixed as soon as possible. Thank you very much.

Hi, FF 89.0b2 Developer edition now contains a "fake editable" search field at the home page (the sentence contains in the class attribute so I used it here), when one start typing in it and the letters appear in the address bar.

For me personally this is partly non-intuitive partly annoying. I never met a scenario in UI of other programs, when typing in one place (where the caret is) show actual letters at another place.

Is this feature is here to stay or are there plans to to make it customizable? I used ff home page search for ages, now I installed a new tab home page extension with manually setting www.google.com in it.

Thanks

From last night, when I open Firefox, a blank white screen keeps appearing. Other browsers work fine but whenever I open Firefox this happens. I'm currently running Firefox on safe mode. Any solution other than uninstalling Firefox? The screen is fully white, no close button, nothing. Just plain white.

The latest Firefox update installed this morning. When Firefox is started, the window opening/close controls in the upper right corner and the scroll bar on the right side of the window are not visible unless the window is set on full screen. Provide a fix ASAP.

So Firefox suddenly and without asking just changed its look into something absolutely... No words can describe level of my disgust, so I wont fill this post by angry ranting.

Is there a way to get the old look back? (preferably without any downloads needed, cos at remote desktops that is not always an option)

Please, don't force me to use Chrome. I hate that browser, but they at least had decency to create skin, which makes it look like Firefox. The normal one, not the new diarrhea all over the screen one.

Firefox is my default browser with Windows 10. I'm running Norton Password Manager (NPM). During the day, I will go in and out of Firefox. I have to restart NPM every time I go back in to Firefox. Any way I can prevent that? Can NPM be automatically started by Firefox each time I call up Firefox?

But Firefox doesn't play the videos on hover. Is there any way to make it?

I've seen some solutions that mentioned creating userChrome and userContent files but they were outdated and I think there should be simpler solution. A friend of mine has basic Firefox version and she said she has never met with such problem.

I've tried:

  • Clearing cache and cookies
  • Creating some Chrome files
  • Disabling addons

I don't think it's Firefox Developer Edition's problem as the issue has been persistent for some time/updates now.
