Frost-for-Facebook VS caprine

It's not EXACTLY what you're looking for, but might do. Frost for Facebook is a pretty good alternate app and still works. https://github.com/AllanWang/Frost-for-Facebook

I also use Frost, love the glass theme.

Facebook: Try "Frost for Facebook". Just updated, even the messenger works. https://github.com/AllanWang/Frost-for-Facebook

Check its Github

If you have access to the source, package.json will have several entries for electron packages. Example.

Second was a small CSS change in a popular project, Caprine. I really had a long back and forth with the maintainer about two seemingly simple changes in a style sheet and I realized I should have been linting my code changes and I learned how to find the css elements I meant to target, it was a small step forward. https://github.com/sindresorhus/caprine/pull/1933 You can still see the remainder of a bunch of requested changes.

The second issue that I wanted to take on I wanted to upgrade from a markdown change like in my first PR. In this second PR I set out to find a small code change to make. After staring at the issue board for an hour or two I finally came across one that I was surprised was not taken. I found this open source Facebook messenger app called Caprine. This was and still is really cool to me, the opportunity to work on something that was so well put together and much larger than my previous project.

Caprine - Nezvanična Facebook Messenger aplikacija za Windows, macOS i Linux - Electron, TypeScript, CSS

I too have faced issues with it on Firefox in the past and moved on to an open source application called Caprine. Works pretty well on Windows/MacOS/Linux.

There in an open source program for Linux/Windows, called Caprine, it's on GitHub ( https://github.com/sindresorhus/caprine ). It has also a portable version for Windows on https://portapps.io , if you are on a machine that's managed by the company you work for (it's like that for me). It's like the official Messenger app for the desktop, but Messenger came out later.

There's an alternative Messenger Client : Caprine

If you absolutely have to use Facebook Messenger, perhaps you could try a free and open-source client like Caprine, which is for desktop, but there was another one for mobile as well, I just don't remember the name of it (as I personally don't use it / have the need to use Facebook Messenger).

I never actually "solved" this, but I switched to Caprine and I'm no longer having any problems. It actually works much better than the official app (it lets you send audio files, etc).
