Browser is slow, freezing, or crashing because of extensions
Browser extensions use memory and processing power. Disable all your extensions, test the browser, then turn them back on one by one to find the bad one. This takes 10 minutes and fixes it.
Browser extensions slow your browser by using memory, running background processes, or conflicting with websites. The fix is to disable all extensions, confirm the browser is fast again, then re-enable them one at a time to find the problem one.

⚡ Before you start
- ✓Open your browser Task Manager (Shift+Esc in Chrome, about:performance in Firefox) and check memory usage
- ✓Count how many extensions you have installed. If you have 20 or more, the overhead alone may be the issue.
- ✓Try opening a simple website like Google.com in an incognito window. Extensions do not run in incognito mode, so if it is fast there, an extension is the problem.

Skip, I just want a technicianCommon mistakes to avoid
- Disabling only one extension and assuming it is the culprit without testing the others
- Removing all extensions at once then re-enabling all of them at once. You lose features and do not know which was bad.
- Not restarting the browser between extension changes. The browser caches old settings.
Signs you need professional help
- If disabling all extensions does not speed up the browser, the problem is not extensions. Give us a call if you see unknown extensions you did not install, or if your browser uses 2GB or more of memory with just a few tabs open. That can be malware or a hardware issue.
