TabTrekker

https://addons.mozilla.org/en-us/firefox/addon/tabtrekker/ Based upon the description of that extension I would say that certain features need to know where the user is located to be able to provide weather data, and that could trigger "sharing" your location. And possibly the time, too, if the developer of that extension wanted it to reflect "local time" for the location where a mobile device would be used vs. the time set in the operating system which is what Firefox would use.

My advice is to check the options in that extension and see what can be disabled from the UI. Beyond that, a custom preference that was created by that add-on may need to be disabled, but I can't tell you what that preference might be without installing it and fiddling with it.

Or, explain exactly which features provided by that add-on are necessary for you to have, and then maybe one of us can offer up alternative add-ons that wouldn't use location sharing.

For an alternate new tab page, I use New Tab Tools - https://addons.mozilla.org/en-us/firefox/addon/new-tab-tools/ - to provide a custom New Tab page. And with New Tab Tools I have a background image that is saved on my hard drive; personally, I can't see using an image on a website and have that image download every time each time I open a new Tab. When I get tired of looking at the background image I go back to one I used in the past or download a new image when I see one that I really like better.

As far as changing the Homepage, that is done quite easily. See - How to set the home page I change my Homepage to the two websites that I use most frequently.

Thank you for your well-written response and for your recommendation on another new tab page! I tried to see if I could disable but I didn't really see a way, so I think I will be using that New Tab Tool add-on instead, since it does not use my location.

When you setup New Tab Tools, just make sure that you don't set up a background image that is hosted on the internet which is the default way that extension works. You'll need to use browse (rather than inserting a URL) to look for an image on your hard drive to use as the background image on the new tab page.
