Teams has switched to Microsoft's own edition of the same concept, "Edge WebView2". Now that Edge is just being Chrome wearing a rubber Scooby Doo mask, I don't expect the differences are vast.

Another fun iteration is Plex's desktop client, which uses QtWebEngine... however surprise! still the Chromium engine underneath.

Signal's desktop app is plain old Electron though.

Of the ones on your list, worth noting that Discord and Slack work fine with FirefoxPWA.

Discord bitwarden steam and teams all work fine for me in ff, i don't use the others

Works like a charm.

It's not FUD but there's usually more to it than just "Firefox". Usually has something to do with security plugins. There are sites that do not work properly with Ublock or Noscript installed, even when you turn them off for the site. I've experienced it many, many times. It happens to me most often ordering food, because a lot of local restaurants sites are janky as fuck, but I've also had issues with more well known sites. Southwest airlines has been problematic for a couple years now. My credit union also had issues with parts of their online banking app, but that thankfully got fixed after a year or two.

TL;DR - it's a real thing.

Costco Travel login page never loads for me in Firefox. Specific sites my kids use for school don't work either. I wouldn't say it happens regularly, but often enough to be annoying.

Walmart.com didn't work for me on FF for about a week, and it did work on edge and chrome (still broken on FF when I disabled all my add ons). However, they fixed it and it works now. I think it was just a problem with the build of the website, and wasn't intentional because it definitely works now.

I think that's what's more likely - temp problems that could affect any browser until their web dev fixes it. Not anything malicious like intentionally blocking a browser.

And then, it's just Walmart. It's nothing that really mattered.

I was worried about this when I originally switched from Chrome to Firefox earlier this year but I can honestly say I haven’t found a single site that I personally use that I had to go back to Chrome for. Any issues I had with any site were related to ad blocking using uBlock or DNS based blocking I also do.

The payment provider my local council uses doesn't work on Firefox, or Safari. I have to use shitty chrome on my phone. I refuse to install it on my computer.

I have issues with twitch. Given I only watch every 3 months for the POE announcement live stream, I just open brave for that one site. I have not tried to figure out if it's my setup or not

It happens to me with some payments stores. Always need to go back to chromium based pos browser

dialog boxes will just fuck off. I've never gotten webRTC to work properly, though that might be configuration skill issues, and or webRTC implementation skill issues, since it seems to only work on browser, not across two different ones.

I've seen sites just load asinine layouts, borked kerning, completely fucked text handling. Just goofy shit.

In some cases i've seen sites have no download buttons on firefox. I don't know why, it's confused me a few times though.

T-mobile would be the last specific one. I couldn't navigate to certain pages within to make plan adjustments.

That's what I do and I haven't had a problem since.

This breaks any site that uses CloudFlare's Turnstile for me. It will loop forever and never let me through if my user agent is set to Chrome.

My insurance site (MyCigna) started working a couple months ago, but for years it failed to log in. It's those types of contracted apps that seem to fail the most for me, like apps you'd see on a company intranet.

Libredirect extension will redirect to public proxitok instances so you could watch them without going to tiktoks site directly

The only problem I run into is sites that use Bluetooth or USB APIs to talk to a local device. Both Firefox and Safari don't implement them due to security concerns.

I really hate the corporate IT.

I was at a job that was slowly transitioning from a medium sized company to a larger one, initially we were allowed just install and use whatever on our machines, but gradually IT started implementing policies where if we wanted to add something it had to go through a request system and usually it would be denied.

As a software developer this was just infuriating, it would hold up work, force us to use shitty software (like Chrome and Edge) and there would often be fuck ups where installing a new version of software would require removal of the old one and installation of a new one - which would trigger the approval process again.

Like - I get it - some people can’t be trusted, but we were some of the key devs for the companies product, we know what we’re doing.

I was rather happy to leave that part of the company behind when I left.

My company just plain old won’t install Firefox without a good reason.

If you have other potential employers in mind, the IT environment at your current employer and other potential employers is maybe one factor to keep in mind in making decisions as to where to work.

There are some IT policies that are no-gos for me at potential employers. I ask during the interview process.

No, they are always right! (^Especially^ ^when^ ^they^ ^are^ ^wrong...^)
