Key notes
DebugBearrecently analyzed 26browserextensions to study whether Chrome extensions are slowing down your computer or not.
The test was carried out on some of the most popular extensions, such as Adblock Plus, uBlock, HTTPS Everywhere,LastPass, and Grammarly among many others.We are here today to answer the same questions, do Chrome extensions affect the performance of your browser? Let’s find out!
Do Chrome extensions affect performance?
Although many Chrome extensions can run additional code on every page that you view, well-built extensions will only run code when it is required to do so.
Activity on the CPU can cause a page to hang and become unresponsive, increasing the amount of battery that must be used. However, if the processing takes place after the initial loading of the page, the effect on the user experience might not be as significant.
A few extensions, such as Loom and Ghostery, execute a significant amount of code without affecting the time the page begins displaying.
However, some extensions such asTotal Adbllock, Clever, Lastpass, and DuckDuckGo Privacy Essentials begin executing code as soon as the page starts loading, which delays the time the user can initially access the website’s contents.
Does Grammarly slow down your computer?
Yes, Grammarly slows down Chrome. On-page CPU time was reduced by over 100 milliseconds for users of Grammarly, Microsoft Office, the Okta Browser Plugin, Avira Safe Shopping, and Avira Browser Safety.
Does Honey slow down your computer?
Unfortunately, Honey slows down your computer as well. There is evidence that widely used browser add-ons like Honey, Evernote Web Clipper, and Avira Browser Safety can considerably slow page load times.If you wonder whether LastPass is slowing down Chrome, it does. It was found to be one of the culprits that caused the browser to slow down.
Quick Tip:
GoogleChromeis known for taking up most of your RAM and CPU. Using a different browser that allows full control over how much it eats from available resources has a huge impact on browsing.
Opera GX is built using the sameChromiumengine asGoogle Chrome, so all Chrome extensions are compatible. It also comes with a built-in CPU, RAM, and bandwidth limiter.

How do I make Chrome extensions faster?
The conclusions of this analysis are not at all surprising. They confirm what many usersalready noticed, Chrome extensions are slowing down your computer. Specifically, certainbrowserextensions may increase power consumption.
This happens because these extensions put a strain on yourCPU. Let’slook at some numbersto see which extensions require yourCPUto do more work.
Things Chrome extension devs should consider
Chrome extension developers need to consider the following points to reduce the impact their products have on the browsing experience: Content scripts should be used on the domains as per the requirements.
Secondly, the content script should not be run on document_start. The developers should avoid overloading the code with JavaScript. It can be loaded quickly whenever you need to include the JS bundle.
Main takeaways
The researchers have also mentioned some key findings of the study. Theperformancecost of the single extension can be small, but the combinedperformancecost might add up to a significantly large value, thus causing Chrome extensions to slow down computers.
Theperformancecan significantly be improved by usingprivacy toolsin those cases when the website is overloaded withanalytics or ads.
The study also has some limitations as well, it has only considered just a singlebrowseri.e Google Chrome. We have to extend the research to other popular browsers to find out how the results vary with respect to eachbrowser.
Furthermore, the sample size should be kept large by increasing the number of extensions in future experiments.
In short, the study revealed that Honey and Grammarly are extremely slow as far as browsingperformanceis concerned.
Thepower consumption is usually increasedwhen you have so many extensions installed in your system. The extension developers should follow the best practices in order to avoidperformanceproblems in the future.
Privacyis amajor concern these daysin view of the recent cyber-attacks anddata leaksby 3rd party apps and programs. Experts recommend that you should reduce the number of extensions installed in yourbrowser.
How can I improve my browser performance?
You may improve the performance of Google Chrome by installing a specialized extension if you find that it is not as quick as it was in the past.
However, the challenge is that many of these products are on the market, each of which asserts that it is superior to the others.The performance can only be improved by installing those shown to be beneficial. Extensions affect performance; depending on the extension, they can either make Chrome run faster or slower.
That is the only way toincrease your browser’s performancealong with ensuring thesafety of your sensitive data. And if you’d like anad-free experience on YouTube Music desktop, we have the perfect tricks.
So, do extensions slow down Chrome? The short answer would be yes, but it depends on the extension, amount of RAM, CPU power, number of open tabs, and other factors.
How many extensions are currently installed in your browser? In the comments section below, let us know which of them is the real culprit behind any performance issues you may have experienced.
