Browser slow? What actually helps (and what doesn’t)
Browsers get slow for predictable reasons, and the reputable fixes are all built in. Do these three first; they resolve the large majority of cases.
1. Close tabs — each one costs memory
Every open tab runs as its own process with its own slice of RAM. Thirty tabs is thirty mini-apps. Close what you’re not actively reading; save “read later” links to the browser’s Reading List instead of leaving tabs open. On a machine with 8 GB of RAM or less, this is the single biggest fix.
2. Audit your extensions
Extensions run constantly in the background, and one bloated or badly-made extension can slow every page. Open chrome://extensions (or edge://extensions), disable everything, and see if speed returns — then re-enable them one by one to find the culprit. Remove anything you haven’t used this week.
3. Clear the cache
A bloated or corrupted cache slows page loads. Settings > Privacy and security > Clear browsing data > tick Cached images and files > Clear. (Leave passwords and history unless you specifically want them gone.)
4. Turn on Memory Saver
Modern Chrome and Edge include Memory Saver (Settings > Performance), which freezes tabs you haven’t touched recently and reloads them when you return. If you keep lots of tabs open on a modest machine, this makes the active tabs noticeably snappier.
5. Update the browser and restart it
Browsers update almost weekly with performance fixes. Check the About page to force an update, then fully quit and reopen — days-long sessions accumulate leaks that a restart clears.
When it’s not the browser
If every browser is slow and so is the rest of the computer, the problem is the machine, not the browser — see our guide on why your laptop is slow. If pages are slow to load but the browser itself is responsive, it’s your internet connection or Wi-Fi, not the browser — check that separately.
What to skip
Ignore “browser booster” and “PC cleaner” tools that promise to speed things up. They duplicate the built-in cache and memory tools while adding their own load, and several are the scareware this site warns about. The four steps above are all you need.
Frequently asked questions
How many tabs is too many?
There’s no hard number, but on 8 GB of RAM, more than 10–15 active tabs starts to bite. Reading lists and bookmarks are free; open tabs are not.
Does clearing cache log me out of everything?
Only if you also tick cookies. Clearing just “cached images and files” keeps you logged in.
Is a different browser faster?
Chrome, Edge, Firefox and Safari are all fast and well-optimised. Switching rarely fixes a slowdown caused by tabs and extensions — those habits follow you. Fix the habits first.
