I'm searhing to method to get chrome version from my background scripts. I have a Background class and create with new Background(). I need to check chrome version when extension is started and if version < 80 I need to send message to user.
well, there is no way to make it from background scripts, but I found that in manifest json I can add "minimum_chrome_version": "80.0.3987.149", and this way extension won't start

How do I check connection type (WiFi/LAN/WWAN) using HTML5/JavaScript?

Closed 8 years ago.
Is there a way to enforce browser or web page to use 3G network ( not Wi-Fi ). I don't want to use any native code, I have to do this in JavaScript code.
It's not so simple at the moment. The browser would have to give out that information. Firefox started recently an experimental feature which allows this via the navigator DOM object, but it's the only browser that supports it so far.
Check out navigator.connection.

Can you get a list of Firefox add-ons programmatically
(2 answers)
Closed 9 years ago.
I need to check, whether my Firefox addon is installed or not when users log into my website. If addon is not installed then users will see an alert to install the addon and if addon is already installed then there will no alert.
There is no direct method to check if an add-on is installed or not. This question was also asked here before. Please see. How to check with Javascript if a Firefox 3 Add-on / Extension is installed
If it's your own add-on then you can write some custom javascript method to try to communicate with your add-on and then display alert accordingly.
