Hi, please try a Refresh but Note that this does more than uninstalling and re-installing does. Normal uninstalling does not remove some preferences which may have become corrupt. Please Refresh but do this 1st: Delete your Cookies and Cache and TEST.

then

TEST....... If no issues then Extensions which need to be added back in 1 at a time and tested ..... Or it is your Profile : Make a new one and test ...:

If is your Profile :

Note: Any customization will revert back to default, you will also need to reinstall Extensions.

I have tried to no avail it didn't solve

You tried making a new Profile, is that correct ?

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

did that too no help

not a new profile

Did you check the settings in your Ubuntu distribution in case there is a setting to hide these control buttons?

Are you running Firefox in Full Screen mode?

Try the Firefox version from the official Mozilla server if you currently use a version from the repositories of your Linux distribution.

I'm not sure how to check settings in my distro still learning I will try the other things and post my findings

nothing has helped

here is my fix that i needed
