- Click the three dots in the top corner
- Head to Settings
- Find Privacy & Security → Clear browsing data

- Switch on “Clear cookies when Chrome shuts down”
We at Nimble Nerds reckon this is a ripper way to keep your browser running smoothly.
Sorting Out Firefox Cookies

Firefox is a beauty when it comes to privacy, but it needs a good clean-out too.
Firefox Clean-up Steps:
- Firstly, open up Firefox
- Secondly, click the menu button (looks like three lines)
- Thirdly, go to Settings → Privacy & Security
- Then, scroll down to Cookies and Site Data
- Next, click Clear Data
- Tick the cookies box
- Finally, hit Clear
Auto-Clear Setup:

We’ve seen heaps of browser dramas fixed just by regular cookie clearing. Fair dinkum!
Clear Computer Cookies in Microsoft Edge: A Quick Guide

We at Nimble Nerds reckon Edge might be storing more data than you’d like. Those pesky cookies pile up fast (sometimes reaching hundreds of megabytes), and before you know it your browser’s dragging its feet.
Quick Cookie Clean-up
- Firstly, fire up Edge
- Secondly, look for those three dots up top (yeah, the ones in the corner)
- Hit Settings, then find Privacy, Search, and Services
- Spot the Clear browsing data section
- Now, choose what to clear

Set-and-forget Cookie Clearing
We’ve found the auto-clear feature’s a real time-saver. Here’s how:
- Pop into Settings > Privacy
- Look for Clear browsing data on close
- Switch on Cookies and other site data
Pro tip: Edge’s tracking prevention’s pretty solid. Whack it on Strict mode and you’ll block most third-party cookies straight up. Though fair warning – might make some sites chuck a wobbly.

Safari Cookie Clean-up: Mac Edition

We at Nimble Nerds reckon Safari’s pretty good with privacy, but those cookies still stack up like Tim Tams in the break room. That is why, after checking hundreds of Macs, we’ve spotted that most users’ Safari browsers are carrying 50MB+ of cookie data.
Quick Clean-up Steps
- Open Safari (obvious, but hey)
- Click Safari up in your menu bar
- Find Preferences
- Jump to Privacy
- Hit Manage Website Data
- Choose Remove All or pick specific sites
Block Those Pesky Trackers
We’ve tested heaps of configurations, and here’s what works best:
- Switch on Prevent cross-site tracking
- Block all cookies (though fair dinkum, this might break some sites)
Pro tip from our tech desk: Safari’s already doing a fair bit of tracking prevention out of the box, but giving it a good clean every fortnight keeps things running smooth as. (2)
Selective Cookie Clearing: Just the Sites You Need

We at Nimble Nerds know that sometimes you just need to clear out one troublesome site without nuking your entire cookie jar. Most users we’ve helped only need to target specific websites that are acting up (usually social media or banking sites that get a bit tetchy).
Clearing Cookies on Your Computer: Browser-by-Browser Guide
Chrome
- Settings > Privacy & Security
- Find Cookies and site data
- Click See all site data
- Chuck the site name in the search
- Hit Remove
Firefox
- Head to Settings
- Privacy & Security
- Manage Data
- Pick your site
- Give it the boot
Edge
- Settings
- Cookies and permissions
- Search the dodgy site
- Remove it
Safari
- Preferences
- Privacy tab
- Manage Website Data
- Find and remove
Pro tip from our testing lab: If your favourite news site keeps chucking you back to the login page or your bank’s acting weird, try clearing just that site’s cookies first. Works a treat most times.
Cookie Types: The Good, The Bad, and The Tracky
We at Nimble Nerds reckon it’s time to sort out which cookies are fair dinkum and which ones are just sticky beaks. After testing thousands of websites, we’ve found most sites drop anywhere from 5 to 50 cookies on your device (bit excessive, if you ask us).
The Two Cookie Crews
First-party Cookies
- Come straight from the site you’re on
- Remember your logins (dead handy)
- Keep your shopping trolley full
- Save your dark mode preference
Third-party Cookies
- Sneak in from other sites
- Track you across the web
- Power those ads that follow you around
- Collect your browsing habits
Block Cookies – Sneaky Ones
Chrome
- Settings > Privacy & Security
- Site Settings
- Block third-party cookies
Firefox
- Settings > Privacy & Security
- Crank up Enhanced Tracking Protection
Edge
- Settings > Cookies permissions
- Block the third-party ones
Safari
- Just tick Prevent cross-site tracking
Pro tip: Third-party cookies are about as necessary as a screen door on a submarine. Block ’em and you’ll hardly notice a difference – except fewer ads following you around like a lost puppy.
Cache and Cookie Clean-up: The Ultimate Guide

We at Nimble Nerds see this all the time – browsers stuffed with more junk than a garage sale. Most computers we check are lugging around 500MB+ of cached files, slowing things down like a koala after lunch.
Quick Cache Clear-up
Chrome/Firefox/Edge
- Find Clear browsing data
- Tick those cached files
- Give it a burl
Safari
- Preferences > Advanced
- Switch on the Develop menu
- Empty those caches
Smart Cookie Management
Been testing heaps of methods, and here’s what actually works:
Daily Browsing
- Chuck on private browsing for dodgy sites
- Install Cookie AutoDelete (absolute ripper)
- Privacy Badger’s not bad either
Website Settings
- Check those cookie popups (don’t just click accept)
- Limit tracking where you can
- Use temporary access when possible
Pro tip: For our business mates, we’ve found setting up proper cookie management saves more headaches than Panadol. Most companies we work with are carrying way too much digital baggage – clearing both cache and cookies monthly keeps things running smoother than a fresh jar of Vegemite.

Frequently Asked Questions- Clear Cookies on Computer

Why do cached images and files stay on my computer even after I’ve deleted cookies?
After someone is done clearing cookies from their computer, they might notice that cached images and files stay. This happens cause the browser cache works differently from cookies – it’s like having two separate drawers in your desk. The cache stores web pages and pictures to make sites load faster the next time you visit them. To properly clean everything up, you’ll need to clear both cookies and the browser cache. For most computers, you can press Control (or Command for Mac) + Shift + Delete to bring up a pop-up window. From there, you can tick the cached images and files box as well as the cookies box. This will clean out all those stored bits and pieces.
What’s the deal with site preferences resetting after clearing cookies?
You have to take note that clearing cookies can shift your site preferences as cookies are actually what remember your site set up. So once you remove them, the website’s settings will be cleared out like dark mode settings. language choices, and even shopping cart items. That is why, your frequently visited website might look different when you visit it again. To keep your preferences while wearing your cookies, you can manage cookies in your browser settings and choose only specific sites to keep. By doing this, you can keep what’s important while reducing tracking from other sites. Finally, remember that login credentials might be asked again for some sites.
How come my computer seems slower after automatically clear cookies is turned on?
Setting up automatically clear cookies might seem like a good idea for privacy, but it can actually make browsing feel like walking through mud. Every time someone visits a website, the browser’s gotta download everything fresh – no cached web content to speed things up. This affects the online experience cause the browser can’t use any stored information. To fix this without giving up privacy, try setting the auto-clear to happen only when closing the browser window instead of all the time. Go to more settings, find the cookies section, and adjust when the clearing happens. This keeps browsing habits private while not slowing down the whole online activity.
What’s happening when the address bar suggests old sites I’ve already cleared?
Even after someone’s gone through and done a proper clear cache and cookie clean-up, the address bar might still show old suggestions. This happens cause browsers keep different types of data in separate spots. The browsing history and other data that makes those suggestions pop up is stored somewhere else. To sort this out proper, click manage in the browser settings, look for the address bar suggestions section (it might be under more tools), and select delete on that specific history. This helps prevent websites from showing up in suggestions when they shouldn’t be there anymore.
Why do some websites still remember me even with an updated version of cookies cleared?
Sometimes websites seem to have better memory than an elephant, even after clearing cookies. This happens cause modern sites use different ways to remember visitors, like local storage or something called cache storage. These aren’t regular cookies, so they don’t always get cleared with the normal delete cookies process. To properly ensure cookies and all related memory bits are gone, open chrome or open firefox (whichever you’re using), head to the top right corner, click more tools, and look for something called ‘Clear browsing data’. Make sure to tick all the boxes under ‘Advanced’ or ‘More settings’ to get rid of everything proper.
