Choosing well
Check Android support
Look for a mobile extension or Android app if you browse on a phone or tablet. Extension support on a desktop does not by itself confirm Android support.
Compare Android with web, Windows, macOS and iOS availability so the tool fits the devices you use.
Match your browsers
Supported browsers are a key comparison point for an extension. Confirm that the browsers you use are covered before signing up or moving settings.
Review free and paid terms
A free plan can cover basic use, while a paid plan may be required for additional features. Compare the listed paid-from price and check whether a free trial is offered.
Read the pricing details before relying on a feature for regular work.
Consider offline use and sync
If you need access without a connection, check the Works offline field. Cross-device sync matters when you move between a phone, tablet and computer.
Confirm that sync covers the data or settings you want to carry between devices.
Check the code licence
Open-source code is available from tools in this category. If that matters to you, check the tool's licence and what the project makes available.
Questions people ask
Do browser extensions work on Android?
Support varies. Check whether the listing offers a mobile extension or Android app; desktop extension support does not confirm Android support.
Can I use a browser extension offline?
Some tools support offline use. Compare the Works offline field and confirm which functions remain available without a connection.
Do extensions sync across devices?
Cross-device sync varies by tool. Check the sync field and its details before expecting settings or data to follow you between devices.
Are browser extensions free?
A free plan is available from tools in this category. Pricing can also include paid plans, and a free trial may be offered.
Does open-source mean the extension is free?
Not necessarily. Open-source code and pricing are separate comparisons, so check the licence and the plan details independently.
