1592508 - The add tab/plus button no longer visible

Status: RESOLVED INCOMPLETE

(Firefox :: Toolbars and Customization, defect)

Hi,

Firefox doesn't show plus button (aka add new tab button). I know maybe it gets fix by refreshing Firefox, but I don't want to do that. refreshing is just pain in the a**, I have some extensions and settings and ... and re-config them is not the good option for me.

If you open customize mode (hamburger menu > customize), does it show up there (it would look like a tab with a little + next to it)? You can drag/drop it back to where it belongs. You can also click "restore defaults" there to restore the default toolbar layout, though you may need to drag extension icons back where you want them in that case.

If the icon is not there, can you attach a copy of about:support's raw data?

I tried that before reporting the issue, doesn't work.

It works, but just for current session, I mean if I close Firefox and open it again, I have to do this again.

Is there any sensitive data there?

Can you elaborate? Does any of the toolbar configuration change back to the default settings, or does nothing seem to change? Or does it change but only for that session? Or something else?
And are there errors in the browser console (not the web console, the browser console - use ctrl-shift-j to open it; you probably want to clear it when opened and then press 'restore defaults' and see what, if any, errors appear).

This suggests your prefs file is not being saved correctly or it is being overwritten by other things.

Do you have a user.js file in your profile? And if so, does it contain a line with "browser.uiCustomization" ?

Not anything I would consider sensitive, though if you click the "copy text to clipboard", and paste in a text editor, you can remove bits you would prefer not to share that aren't relevant (e.g. printer, audio and graphics data) before leaving the result here.

restore defaults works as expected, but it doesn't do anything with add button.

And are there errors in the browser console

No, there was no any log (error, info, ...)

Do you have a user.js file in your profile?

No, I just use userContent.css

Can you please do the following:

1. open the browser console.
2. evaluate CustomizableUI.getWidgetIdsInArea("TabsToolbar") and include the result in a comment here.
3. open customize mode, move the button to the right place, close customize mode
4. repeat step 2 and include this result, too (should now include the new-tab-button)
5. open about:config, copy the value of browser.uiCustomization.state and put it in the comment.
6. restart Firefox. Per comment #2, it breaks again then?
7. repeat step 2 and 5 .

I don't really understand what's happening here, tbh. For context, does changing other prefs still work after a restart?

Sorry for delay. I had to re-install the Windows, so the issue is not there anymore. I'll update this page if anything related happens. thanks.
