Choosing well
Check Android and device support
Check the product's supported devices before choosing an extension for a Xiaomi, Redmi or POCO phone or tablet. Platform listings can include Android, iOS, macOS, Windows, web and extensions.
Confirm that the browser and device you use are supported, rather than assuming desktop extension support carries over to mobile.
Match the browser and job
Compare supported browsers with the browser on your phone, tablet or computer. Read the primary function so a blocker, password manager, translator, writing tool or note app fits the task.
A web version may be useful when a browser extension is not available on your device.
Read the free and paid terms
Look for a stated free plan, free trial and paid-from price. Check the free-plan limit so you know what stays available without payment.
Pricing models include freemium plans, so compare the included features and the point at which payment starts.
Review code and team features
If you need to inspect or change code, check whether the project is open source and review its licence before choosing.
For shared work, compare team-sharing support and the supported devices listed for the plan you need.
Questions people ask
Will an extension work on my Android phone?
Check the product's supported devices and Android listing. Browser-extension support can differ between desktop and mobile browsers.
What should I compare between extensions?
Compare supported browsers, primary function, supported devices, free-plan limits, paid-from price and team sharing.
Can I use an extension without paying?
Look for a real free plan or a free trial. Freemium products may place limits on the free plan or charge for added features.
Does open-source code matter?
It matters if you want to inspect or modify the code. Check the project's licence and the scope of the code offered.
Are these tools available on Windows or macOS?
The category includes products with Windows, macOS, web and extension platforms. Check the supported-platform details for the product you want.
