Remove Firefox 60 new tab upon opening Firefox?

[scd]

Hey Folks,

Just update to FF 60 ESR and want to find out how to remove the new tab when I open FF so that it's just a blank page until I click on a link and THEN it opens a tab....HOW DO I DO THIS??!!

Thanks,

Clint

Not sure if this is the same in 60ESR as it is in 62.0 but try menu path Tools->Options->Home->New tabs->select "Blank page" from the drop down list.

Nope, that doesn't get rid of it....still there when I open FF...I think it might be a setting in about:config but WHICH ONE has me LOST!

[DanRaisch]

Oops, you're talking about when Firefox launches. Try menu path Tools->Options->Home->Home page and new windows->select "Blank page" from the drop down list.

The old selector to change your startup page to a blank page independent of your home page and new tab page settings is gone from the Options page, but the underlying preference remains available:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.

(2) In the search box above the list, type or paste startup and pause while the list is filtered

(3) Double-click the browser.startup.page preference to display a dialog where you can enter '''0''' (that's a zero), then click OK

Tried that and I'm still getting a tab when I start firefox......I'm running a custom USER CHROME file and I'm wondering is this could be a source of the issue? Here's what I have it set to now:

ENABLING options: remove the combination of / and * before '@import'
DISABLING options: add the combination of / and * before '@import'

FIREFOX BUGS (nothing CSS code can do about):
- some '@import' calls might not work properly on macOS and Linux
- some '@import' calls might not work properly, if multi-process mode (e10s) is disabled
- in both cases CSS code has to be added to userChrome.css file manually

macOS issues / glitches / fixes -> look for 'macOS fix' additions inside this file
- tabs toolbar spaces in 'toolbars' category
- tabs not on top mode in 'tabs toolbar position' category
- page context items in 'general ui' category

Some CSS tweaks won't work, if '@namespace' references are used inside '.css' files!

EXPERIMENTAL settings are for testing only!

Try launching in Mozilla Safe Mode which, among other things, causes Firefox to ignore any userChrome.css files on start up.

how to remove the new tab when I open FF so that it's just a blank page

When I open Firefox I just want the browser to open in a blank window and not a tab........Right now it opens with a blank tab. I 'm not really dealing with this issue much right now, I had a death in the family on Tuesday and so, am dealing with that loss. When I feel up to it I'll reexamine the issue then....Thank you!

When I open Firefox I just want the browser to open in a blank window and not a tab........Right now it opens with a blank tab.

As far as I know, there is no such thing as a Firefox window without at least one tab. Firefox is not an MDI application like Microsoft Word that displays a window with zero documents open.

[lasardo]

This is not a total solution to your question, but might lead you in the right direction. In about:config there is a setting browser.tabs.closeWindowWithLastTab , the default is true. If you set it to false, a long time ago at least, you could close the last tab and leave Firefox open without any tabs, I think - or maybe it just cleared the last tab and replaced it with blank? I forget. So, you could try it - set to false, then click the close x for the last tab and see what happens.

[LIMPET235]

Lasardo...
Thanks. To refresh your memory...your suggestion will just inhibit Firefox from closing when closing the last tab.
It will remain open with just one blank tab.

As noted...^^....Firefox will not show a blank window.
Even the 2 options in... File > New Window & New Private Window will open in a new blank tab.
