Help: advice & tools for digital detox / minimalism?

Hello, I was wondering if anyone has recommendations for tools to help with digital detox / digital minimalism.

I struggle with mild impulsivity. Whenever I open my computer I almost automatically open a browser and check social media.

It used to be a problem primarily with Reddit and news sites, but since joining Lemmy my behavior has switched to regularly checking Lemmy.

I'm looking for any tools or advice, whether cognitive-behavioral or technical like browser extensions.

In the past I used the Firefox extension called Redirector to redirect myself from certain subreddits like /r/all to something more benign (I like /r/sewing or /r/books for example), and this intervention helped break up automatic behavior and was a kind of harm reduction: still feeding the impulsivity, but with healthier content.

I was wondering if there is something like Redirector that redirects randomly with some probability (like 20% of the time it redirects to the target you specify).
