Let’s see if I can give at least something understandable. To start with, definitely not past tence.

If you ask “would you like coffee?” you’re asking in the present if coffee is something the person wants to drink now. If you ask “would you go to the store?” you are asking if the person doesn’t mind going to the store.

Could is similar but is slightly different, is to ask if the person can do something.

Could you take out the trash ? - are you able to take out the trash?

Would you take out the trash? - do you mind taking out the trash?

Not sure this helps, but in project management there’s this think called the MoSCoW scale to define how important a requirement is, it looks like:

Must (you have to do it)

Should (very important but not as important)

Could (not important but if you can you should do it)

Would (would like to have, this is definitely not important but if you have enough time it’d be great)

URLCheck could be what you’re looking for.

It acts as the default browser but then pops up a window to ask you where to open the link, does it every time. I thought I would be bothered by that part but it’s so much better. You get to choose to open in Firefox private mode even in the in app browser. Links here on lemmy open through Sync (and Connect if I’m not mistaken) open in app on Firefox private mode.

You can also remove trackers from URLs, choose the default app per domain, love it
