> but a lot of popular sites don't even work with Firefox

Which ones? I have always exclusively used Firefox and rarely have issues.

Count me in as well. I only use Google Chrome for Google meet calls, as some feature are not working on Firefox (I'm sure this has nothing to do with the fact that Google makes both chrome and meet ;)

Meet also does not work properly in Safari, each time I have a meet call I need to use Chrome, so Google might using non web standards.

Does it work in Ungoogled Chromium? I use that just on principle when nothing else works (which, in agreement with the previous posts, is rarer for me than people seem to claim)

My goto example is roll20.net. During a gaming session some feature or thing didn't render. Switch to chrome... worked perfectly.

The real problem is that firefox is tier 2 support or not even. It's a small percent of users so it's a cost/benefit for these businesses.

A recent issue I had was buying tickets from air india. You can't with firefox... it'll hang at a certain point. Switch to chrome... works perfectly.

The web is dead. It's basically client/server nowadays. Firefox is still my main browser, but I keep chrome/chromium around when I need it.

Thanks for trying to use Firefox first!

You can report websites that don’t work in Firefox on webcompat.com and Mozilla web developers will test and diagnose the problem. When possible, they attempt to reach web developers at the site (using personal contacts or referrals when official channels aren’t working) to share the bug report and a suggested fix.

In other cases, Firefox can include a site intervention script to patch the site or send a different browser User-Agent string to make it work.

Same here, I've been using Firefox for about five years now, and it seems like it opens absolutely all websites

I can't get Reddit to work in Firefox or Chromium. No idea why.

[jraph]

It's often an extension. Maybe you happen to use the same problematic extension(s) on both Firefox and Chromium. Maybe try with an empty profile :-)

[stuaxo]

Weird, I use it with Firefox every day.

Have you tried either in an incognito/private browsing session? If it works there then it could point to needing a cache/cookie clear. If not then the issue may lie outside your box (try a vpn?)

[alpaca128]

Both old and new UI? What problems are there?

I've never had issues loading/using reddit from any browser aside from their annoying "use our app" popups.

[nalinidash]

You may have added it to an adblock filter list by mistake.Try disabling and trying them.

[angiosperm]

Nope, tried that.

A couple of things have helped me solve issues when trying to load sites in Firefox that will work in Chrome/Vivaldi, etc.:

1.) Refresh Firefox: Click the menu button with 3 lines -> "Help" -> "More troubleshooting information" -> "Refresh Firefox..."

2.) Check your Enhanced Tracking Protection settings from the Privacy & Security tab in the Settings menu. If it's set higher than Standard, it could be causing sites like reddit, sites that use Cloudflare for protection, etc., to load incorrectly or fail to load entirely.
