My dock and top menu bar disappear when I am using Firefox

~/Library/Preferences/org.mozilla.firefox.plist delete this file

The file that I told you to delete will just get rid of the preferences, which could be the reason. I deleted the one that I had for chrome and it really sped up chrome but it erased the bookmarks.

If you don't want to erase the bookmarks you can just export them to safari or chrome. If you really don't want to delete the file you can just uninstall firefox then reinstall it.

Just to help to anyone if it is a still issue.

The only way to sort it out without remove anything from your mac is this way:

1.In Finder right click on the Firefox app and select “Show Package Contents”

2. navigate to Contents and open “Info.plist” in TextEdit.

3. In this file, near the top, there should be a piece of text that says <dict>, underneath this add the following making sure all of the text is present.

<key>LSUIPresentationMode</key>

<integer>0</integer>

4. save that file

5. restart firefox

6. happy browsing again

cheers

This solved my problem! Thank you!

And me - weird? ffox 12.0

Also how did you know that and how did ffox start behaving like that? 😕

Thank you.

I have been having the same problem with Firefox13.0.1

Your solution solved it.

I have the same question as bobbyblue -how and why did this begin to happen?

alan

Absolute genius thank you so much

Hello,

this hasnt worked for me for some reason...any other options or reason that I may be messing it up?

thanks

This has happened to me before and it took me a long time to work it out.

But all you need to do is froce quit safari or any application that this is happening to and start the application again.

Hope it works.

Thanks! This solved my problem.

Dear mcgregork,

thanks alot man, you saved me!

SGosai:

This worked for me. Thank you so much for posting. The problem with FF just showed up this morning. Last night, I had to close down my Mac due to a panic freeze. I had been watching You Tube clips of the Oscars on FF when that happened. I wonder if this caused the problem to begin with.

I tried the plist fix posted by mcgregork but it didn't work for me. I deleted that later and then tried your fix, which did work.

Not sure why Firefox started acting up today, but editing the Info.plist file worked. Thanks!
