In Firefox, I occasionally need to clear my cache to fix a website. But clearing the entire cache seems like extreme overkill. Is there any way to just clear the one site from my cache?

From the Firefox menu bar, click on History and then Show All History. Search for the site in the upper right corner. Then right click a page of the site and click F̱orget About This Site.

Looks like we have a winner! I guess this was added somewhat recently? – Ryan Thompson Mar 25 '14 at 17:17
You're still here! Three and a half years later. :) To answer you: yep, "yesterday". Thanks for the kudos. – zylstra Mar 26 '14 at 18:52
This is a great alternative to CTRL+F5 when you want to remove the cache of a website which redirects you to another website (in which case CTRL+F5 only force refreshes the redirected website). – Sicco Sep 4 '14 at 14:35
A good answer but people need to know about the problem! So: W A R N I N G: This will clear ALL info about that web site including cookie and passwords. – Frosty frog Jan 30 at 16:03
Also, if that site is localhost, it will lose data for all localhost sites that you're developing, which is, for me anyway, far more than I want to clear. – Joshua Frank Jul 3 at 12:41

If you want to do a force-refresh, which is what I think you want to do, hit CTRL+F5. And of course, Cmd+F5 on a Mac. Works on Chrome too.

CMD + SHIFT + R ... the function keys are per default used by OSX. – Kenneth B Oct 17 '11 at 9:32
That's not necessarily true. Resources like html templates are cached every time I'm trying to develop. – James South Apr 2 '12 at 18:19
any idea how to do this for a page that was using a 301 redirect to another domain, but is no longer? I haven't been able to hit ctrl-F5 fast enough, and the redirect keeps happening – matt wilkie Apr 18 '12 at 5:06
Don't understand why this answer get's upvoted so much as it's both wrong and doesn't answer the question. Ajax calls, css files, redirects keep being cached (or redirects). The only sure way would be an option to remove history from a certain domain like with removing cookies. Another way is to start firefox with a different (cleaned) profile. – HMR Sep 15 '13 at 3:18

this addon will allow you view and delete specific cache entries from memory and disk -

Sadly, the addon is not available anymore at present. – equaeghe Nov 30 '13 at 21:43
Have a look at this – iceteea Dec 3 '13 at 10:25
This add-on is not in stable version. – Nicolas Barbulesco Apr 27 '14 at 6:50
Apparently, this add-on cannot be hot-installed. This is too bad. I need to make some specific sites work again in Firefox, without relaunching Firefox. – Nicolas Barbulesco Apr 27 '14 at 6:52

There is no built in way to clear the cache of specific pages/sites in Firefox. You can "Forget about this site" which cleans the domain from history, you can "Delete this page" which cleans the specific page from history, but you can't clean up single cache items belonging to a page (apart from going to your profile folder and deleting them).

There may be addons to do this, but I didn't find anything when looking through them. Built-In functionality for cache deletion seems to have the all-or-nothing policy.

Where are the options you mentioned for "Forget about this site" and "Delete this page"? – mouseas Jun 20 '12 at 17:16
@mouseas, at least the history sidebar (Ctrl-H). – Matthew Flaschen May 17 '13 at 21:20
@mouseas Those two commands are at the bottom of the right-click menu of any individual page in history, in the History window or sidebar. – Rory O'Kane Jul 18 '13 at 19:18

Please note that there is currently no way to clear cached HTTP redirects (at least 301 type) without using a plugin.

Ctrl+F5 / Cmd+F5 does not work as you are being immediately redirected to the target URL so you can not refresh the original one.

So I used CacheViewer plugin mentioned here before to deal with this.

See also this bug in Firefox for details and possible progress on this issue.

You may try with turning on the warning before redirect, in the Prefs → Advanced → General → Accessibility. But this pref does not work in all cases. – Nicolas Barbulesco Apr 27 '14 at 7:13
I wonder if that Firefox bug isn't simply about 301 Moved Permanently redirects, which are, well, designed to be permanent. If Firefox would indeed cache 302 Found, then that would indeed be a bug. – Arjan Jul 24 at 7:13
You are generally right about 301 @Arjan but I would say it's at least a questionable behaviour to cache a redirect resulting in 4xx/5xx response. And also not being able to clear these redirects cache without a third-party tool seems to be more like a bug than a lack of a feature.. – Greg Dubicki Jul 24 at 13:12

One day when you have not opened anything else, go to Tools ⇨ Clear recent history and then select to only clear the cache and then only from today or Xtime. Because you just visited the website, it should have moved its timestamps in the cache to the top of the list so you can just wipe all cache from Firefox for that day and thus clear the cache for your specific website.

A lot of trouble to go to for such a trivial purpose. – Isaac Rabinovitch Nov 19 '12 at 22:04

There's a similar question:

and answers shortly are:
- You can use firefox by 2 profiles.
- There's a extension named CookieMonster may works for you:
- There are two add-ons for FF that every web developer needs and they are Web Developer Toolbar and Firebug, the Firebug extension YSlow comes in very handy too.
Web Developer Toolbar has great cache and cookie control down to individual cookies.
- Ctrl-F5 is enough usually.

Those are mostly for cookies. I just care about dropping a domain from cache. – Ryan Thompson Aug 7 '10 at 20:54
Thank you for this summary. But Cookie Monster is not a cookie. Cookie Monster is an extension for Firefox. – Nicolas Barbulesco Apr 27 '14 at 7:00
@NicolasBarbulesco Right, I changed the text. – Amir Latifi Apr 27 '14 at 9:16
