I have problem with deleting all cookies, and all cache.

more options

I use FF for web development, and frequently have to clear all cache, and cookies to see my developed changes. But with the recent update from FF3.16/17 to FF4, I have started to face a weird problem while clearing all cache, and cookies. One is, I have observed that the process takes more time compared to previous versions, and secondly, it gets stuck sometime showing a script error on a file called sanitize.js file.

I have a grab to show, but not sure how can I show it you. but the alert says "A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete."

Script: chrome//browser/content/sanitize.js:136

Below are 2 buttons, Continue and Stop Script

Does it work better if you do not use Delete browsing, search and download history on Firefox to clear the cookies, but do that manually in the Cookie Manager and only use Clear Recent History to clear other items?

I have the same problem.

Yes, deleting every cookie manually works perfectly.

Firefox 4 also tries to clear the cookies from plugins like Flash and starts a plugin-container process with the Flash player and possibly other plugins as well for each cookie, so that can add a lot of extra time if there are a lot of cookies to remove. Also make sure that all plugins are up to date.
