Currently, Firefox has 3 options for scrollbar width: thin, hidden and system default. I'm going to change the label for the wide option because on Firefox the option is whatever your operating system's default scrollbar is.

I'm trying to get the organization in charge of the scrollbar standard (W3C) to add a wide option to Firefox, but it's a long process.

Glad to hear you like the add-on. As of the latest update, most of the tabs should take the changes without having to be reloaded. The reload warning on the settings page has been left there as a precaution to make sure that the changes made actually work as intended. It should be removed in a future version.

Thanks for the feedback! Sorry to hear you are having issues. I'd love to take a look into the Magic Mouse issue for you, although it may be difficult since I don't have a Mac.

If you could either file a bug report on GitHub (https://github.com/WesleyBranton/Custom-Scrollbar/issues/new) or email me at addons@wesleybranton.com with more information, it would be much appreciated. It's helpful if you include your current settings and, if the issue is with a specific website, the URL for that website. Thanks!

Glad to hear that you like most of the add-on! I'd love to be able to offer more scrollbar width options, but unfortunately I'm limited to the two that Firefox supports. I'm hoping that Firefox will eventually expand the scrollbar functionality to allow the add-on to set a custom width, as is currently possible on other browsers.

Sorry to hear you are having issues with the add-on. If you send me an email at addons@wesleybranton.com with some more information about the settings you are trying to use and the page(s) you are having problems with, I'd be happy to try and track down the issue for you.

As a side note, there are some pages that the add-on is not allowed to modify. An example would be the Firefox add-ons website. So if the pages you are having problems with are Firefox pages, that could be the issue.

As well, please note that you currently need to refresh your tabs before the changes will appear on the website. That is being addressed in an upcoming update, but for now you need to refresh the tab. If that doesn't work, trying restarting your browser.

Hope that helps, but if not, feel free to reach out to the email address above. Thanks.

I really like the idea of having a profile system. While I probably wouldn't recommend it for multiple users (I'd actually recommend running multiple profiles on Firefox for that. See: https://mzl.la/3xZQFgI), it does have some good potential for other features that are on my to-do list. I've added it to the list of features I want to add, although it probably won't be added to the add-on for a while.

As for the bug you reported, I've tried to reproduce the issue, but I can't get to happen. If you could either file a bug report on GitHub (https://github.com/WesleyBranton/Custom-Scrollbar/issues/new) or email me at addons@wesleybranton.com with more information, it would be much appreciated.
