I've unfortunately had the opposite experience with FF send, I still use it all the time (or try to) when I find links on mobile that I want to read on a big screen, or when I have an image url on my laptop that I want to send from my phone via SMS, snapshat, etc. But the delay is just unbearably long and inconsistent. Sometimes (most often when sending desktop to phone) the delay is 15 minutes or more. I've found it a lot easier to use a bookmarklet that uses DDG to generate qr codes, but that only solved sharing in one direction.

I've wondered how send could be so slow but maybe something in my setup is just killing it. More than anything though, I would love an easy way to access my phone's sharing options from my laptop (perhaps an addon button that shows a list of app intents that can receive a url/page).

This is one thing I'm hoping to hack at when I get my Librem.

I'm on Android. I use an app called Pushbullet, which mirrors notifications but also enables text and file sharing between all your devices. Sharing is instant. I also enable "open immediately on browser", meaning if I send a link from my phone to my computer browser then it'll automatically open a new tab with that link. It's pretty neat, it's really two or three taps away from any web browser tab on my mobile (open menu, hit Pushbullet shortcut; or open menu, open sharing menu, push to all devices).

I used PushBullet once and send a pornhub link to all my devices which auto played. When I say Autoplayed I mean it started to play on my work machine and I was working from home.

Never rode my bicycle quicker (public transport sucked). Fortunately my computer was on mute but still had to confess to watching certain content on a work machine to my boss. Nothing came of it but all the same.

Be careful. I even posted on r/TIFU at the time.

I use the "send tab to another device" feature a lot, and it's true that sometimes it isn't fast enough to be considered real-time. Sometimes tabs appear instantly, sometimes they don't appear for minutes, and sometimes restarting the browser triggers tab reception. In any case, it's already an awesome feature.

You might want to look into KDE Connect.

Have you tried KDE connect?

You can share links and files with any connected device. Use it as a remote control for music players and presentations. Ring your phone from your computer to find it and more.

(edit: add second paragraph and link)

I love KDE connect. It makes smartphone interaction really seamless. However, it only works in the same wifi (most likely some wifi you control).

PS: Just noticed there is a VPN feature https://userbase.kde.org/KDEConnect#Running_KDE_Connect_over... -- KDEconnect is really amazing.

I usually just message myself on WhatsApp.

I also remember a popular extension that could do this, PushBullets

I use getpocket for saving links to read, which is cross platform, including the web.
