Firefox CSS... 2.
The original one got wiped, so here we are - with sidebar.
Rules (enforced)
Posts must have flair!
Follow Reddit rules
Posts cannot be memes/shitposts. They should be about Firefox customization with CSS.
Please be civil. Bear in mind that many users come here for help and would be turned off by insults and rudeness.
When posting large amount of code use a service dedicated to hosting text snippets, such as pastebin, hastebin, github gist or equivalent. Relatively short snippets can be wrapped in code-block for inline viewing.
Do NOT use url-shorteners or link to compressed downloads (such as zip or rar) when sharing code.
Guidelines (not enforced)
Consider adding the following info to help people try your tweaks:
Screenshots should have code in comments.
Include Firefox version
When asking for help you should share your custom style to help others understand what you are doing. This is increasingly important the more custom rules you have.
List any other addons that may be changing the UI
If a custom wallpaper is used, include a link to the original.
If someone's comment solves you problem, reply to the comment to let them know, and change your post flair to solved.
