Hi, I have a mac and I use the userchrome.css file to place the close tab button on the left side of each tab (visible on both active and inactive tabs). This code has worked fine for several years. However, this past week it has stopped working. Looks like the problem started with the upgrade to version 113.0.1. Besides the close tab "x" now showing up on the right(annoying on a mac), the last tab has no close tab "x" at all. To close it, you have to add another tab, which you can't close either.

I would appreciate any suggestions as to how to fix this.

Also, websites have been loading much slower than usual.

Thank you for your help. Debbie

Thanks for the suggestion! Unfortunately, it did not change anything, but I appreciate your help.

Can you post your current userChrome.css ?

Note that -moz-box-ordinal-group is no longer supported in 113 and that you likely need to replace "-moz-box-ordinal-group:0" by "order:-1 !important;".

Thank you!!!!

Replacing "-moz-box-ordinal-group:0" with "order:-1 !important;" completely fixed the problem.

For the future, is there someplace I can check to see if something is no longer being supported in a new version of firefox, whenever one is released. That could save a lot of time/effort in troubleshooting a problem.

Again, thank you for your help. Debbie
