How to activate userChrome.css in v91?

[CarolynC]

I have just updated from v78 to v91. It didn't go smoothly and v91 refused to start (even in safe mode) with my old profile. After unsuccessful troubleshooting, I just started over with a brand new profile. That went well and was faster than expected. But, there's one thing that I have not been able to figure out.

My near vision is not what it used to be and I've been using a simple userChrome.css file to increase the global font size. All it contains is:

/* Global UI font */
* { font-size: 15pt !important;}
* { font-family: Verdana !important;}

I made a chrome subdirectory in my new v91 profile and copied my userChrome.css file into it. But, how do I make v91 use this userChrome.css file?

Alternatively, is there a method in v91 to increase the global font size so that all menus, file listings, etc. use a bigger font?

Thanks in advance for any help.

Did you remember to set the toolkit.legacyUserProfileCustomizations.stylesheets preference to true, then restart?

Thank you, morat. That did the trick. It had been so been years since I wrote and activated the css file initially that didn't remember that.
