stop firefox loading old css?

Question

private browsing and ctrl-f5 doesn't seem to be cutting it?

(i've got a lot of ajax loaded content)

Answer 1

You can append the stylesheet URL with a query string to render the cache as no longer valid. For example, a version number.

<link rel="stylesheet" href="/css/style.css?1.1" type="text/css" />

This is assuming you are looking for a method to invalidate the cache for everyone. If you are simply looking to clear your own cache, this belongs on Super User.

Answer 2

Sometimes I hit ctrl-shift-delete, it prompts for things to delete, I delete the cache and sometimes the cookies. Then I hit F5.

Answer 3

Simple put some variable behind *.css. For example, ? and time() function.

Answer 4

Stick a version number as a querystring to the CSS file:

<link href="/style.css?1" rel="stylesheet" />

Or if you want it to never be cached, stick something like the time there:

<!-- php -->
<link href="/style.css?<?=time();?>" rel="stylesheet" />
<!-- asp.net -->
<link href="/style.css?<%=DateTime.Now.Ticks%>" rel="stylesheet" />

Answer 5

You can also use the Firefox Webdeveloper addon. It has a function to disable your cache.
