Is it possible to clear only 301-redirects from Firefox's cache? CTRL+F5 doesn't do the job since you just reload the target without caching but do not clear the cached redirect.
An option to disable caching of those redirects completely would be fine, too – but some way (possibly through an extension) to remove those cached redirects would be better.
Note: I'm not looking for answers that disable all caching (including CSS, JS, etc.)
I don't think there is a built-in way to stop caching of just javascript within Firefox, but you can stop Firefox from using cached files altogether , which will have the same desired effect for developing. Navigate to about:config in the address bar and filter to network.http.use-cache. Set it to false to stop Firefox from using cached files.
You can do the same with the Web Developer Toolbar:
Note: This will clear saved passwords for the site as well.

Locate the site you are redirected from in the History sidebar. Right-click it and select "Forget about this site".
No addons required!
P.S. I'm pretty sure this didn't work in the past, but nowadays following the redirect and then clearing the cache for past hour will actually remove the cached redirect.
P.S. The current best solution is to use "Web Developer Tools" (Ctrl+Alt+I), click "Network" and click "Disable cache". Load the original URL. Enable the cache again. The page is refreshed in the cache and the original URL is accessible also from other tabs now.
