I use Firefox on Linux and FreeBSD for my daily driver.

I was not able to book flights on Thai airways website 6 months ago until I loaded it in chrome/chromium instead.

It's really really rare imo but that's one example in recent history.

Not a very big website, but the service my therapist uses for teletherapy doesn't support anything outside of chromium.

Wow, that random news article I hit 16 days ago where the page kept flickering and reloading, but didn't do that when I copied the URL into Brave... I really should've recorded that domain so I could defend myself against some stranger online!

Sarcasm aside, I don't think it's generally the major websites that you bump into this with, however, there are many edge cases that occur for plenty of folks, whether they're in college and have to use that "secure browser" extension that only supports Chrome, or the fact that some websites, especially in business, that simply refuse to support browser and will prevent access otherwise.

I'm a Firefox user, so this isn't to say that Chromium is the way by any means, but hopefully to shine a little light on the fact that we're all on different parts of the web with different experiences, questioning their experiences so that you can hopefully find an extension or something to pin the blame them does not absolve them of their experience, just a show of elitism.

Firefox HAS gotten much better, but unfortunately, Capitalism's gonna Capitalism

Oh, and I can't seem to get tiktok videos to play on Firefox on Android? Not a major issue, but my sister keeps sending them to me in particular for some reason, so...

I couldn't submit a support ticket for id.me (the IRS' stupid commercial partner for Identity verification) when using Firefox, the submit button literally did not work. Worked fine when switching to edge (blegh).

Example: The meeting webservice my bank uses is for whatever reason blocked for Firefox. Not sure if they just User-Agent check but they consciously block out Firefox users. I alerted my bank person about that but I doubt that's going to be any different next time I have a meeting with them.

The search in the Walmart site has only been working on and off (mostly off) in Firefox, but consistently in Chrome. There's also some webpages for my university that only work in Chrome

Edit: looks like the Walmart search is working now though for me. The only reason I even have duckduckgo browser is because walmart.com was giving me issues on Firefox

I was about to say this. I never find any websites that doesnt work with Firefox so I'm genuinely curious.

I bet it's their ad blocker, or they have set their Firefox settings to the privacy level that says "this will break some web sites".

I remember whipping out Vivaldi (which is Chrome-based) for booking a ticket on the Interrail website: https://www.interrail.eu/en

I haven’t fiddled much with weaker privacy/ad-blocking settings though, because I didn’t have the patience for that.

I just gave you an example of menus not expanding.

I'm not dogging Firefox I'm saying there is a consorted effort made to reduce it's usefulness.

MS Teams. Works for chat, but not for receiving audio/video calls/meetings.

I can think of 2 websites that didn't work right over the past 10 Yeats. Both were credit card payment sites and just had weird issues like couldn't hit the submit button. I figured it out and just used edge for them. I never found any site that I use often that has issues yet.

Create any website with an element that is fixed on the bottom of the page and try to move the page in the mobile Firefox then.
