How to Restart Firefox Without Losing All Your Open Tabs.

Firefox version 65 has brought with it quite a few new features and tweaked some of the browsers core functions. Users now have access to more content blocking options, with three new preset options available: Standard, Strict, and Custom. As well as this several new languages have been added, and Firefox now automatically follows your Windows 10 accent colours.

Although the option for Firefox to follow Windows accent colours is a nice touch, it isn’t one that has gone down overly well with the community, with quite a bit of backlash already hitting places like Reddit. Thankfully, since Firefox is still a very customisable browser, you can disable this feature, so follow along as we guide you through the process.

How Do You Stop Firefox Using Windows 10 Accent Colours?

To stop Firefox using your Windows 10 accent colours, you’ll need to do the following. First, open Firefox then type about:config into the address bar and press Enter. (you will have to accept a warranty warning to proceed if this is your first time using about:config)

Once you have accepted the warning right-click anywhere in the main window and select New > String. Next, enter the following name and value pairs according to your theme you are using.

Default Theme.

ui.-moz-win-accentcolor = #202340
ui.-moz-win-accentcolortext = #f9f9fa

Light Theme

ui.-moz-win-accentcolor = #e3e4e6
ui.-moz-win-accentcolortext = #18191a

Dark Theme

ui.-moz-win-accentcolor = #0c0c0d
ui.-moz-win-accentcolortext = #f9f9fa

Note: If you aren’t sure what theme you are using click the settings dots in the top right-hand corner of Firefox, then click Customise. At the bottom of this page, you will be able to view or change your theme.

As an example, to get Firefox to honour its dark theme and not Windows theme, the process looks like this. Right-click anywhere in the about:config space then select New > String.
