I'm trying to take off this "Extension (Tabliss)" tag on my url. I have followed the instructions down below from another Firefox support forum: https://discourse.mozilla.org/t/make-addressbar-text-extension-name-of-the-extension-shorter-or-hide/28026/3 The instructions I followed are listed below: "Users can apply custom style rules to modify Firefox’s toolbar area by creating a userChrome.css file. This takes about 10 minutes so when you have time to take it slowly and carefully: (1) Set up your chrome folder and userChrome.css file following the five six steps in this article: https://www.userchrome.org/how-create-userchrome-css.html 45 I have a boring video there if you like demonstrations. (2) This is the code to paste into the file. You can edit the file using Notepad or a better editor. Make sure to keep it in a plain text format with a .css file extension (not .css.txt). See improved rule down in: Make addressbar text "Extension (Name Of The Extension)" shorter or hide <pre><nowiki>/* Hide Extension Name in the identity area unless hovered for half a second (updated for Fx80) */ #identity-box.extensionPage #identity-icon-labels, #identity-box.extensionPage #identity-icon-label { visibility: collapse !important; transition: visibility 250ms ease-in-out; } #identity-box.extensionPage:hover #identity-icon-labels, #identity-box.extensionPage:hover #identity-icon-label { visibility: visible !important; transition: visibility 250ms ease-in-out 500ms; } </nowiki></pre><br> (3) Firefox should read the file at its next startup and apply it to every extension page you load." Edit: So, yeah, I need help getting this tag off. I'm new to Firefox so it could be something obvious I'm missing. I have also tried CTRL+SHIFT+R to reload the page for changes and also closed and reopened my Firefox entirely. Thanks in advance.
