User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/77.0.3865.90 Chrome/77.0.3865.90 Safari/537.36

Steps to reproduce:

Firefox 70 seems to have broken Javascript on lots of sites, often rendering sites useless. Steps to reproduce will be listed with the examples.

This is Firefox 70.0 on Linux MInt 19.1 (64-bit).

Actual results:

Facebook: Nothing appears in the news feed. (Steps: Navigate to https://www.facebook.com/ and log in.)
Tweetdeck: Gets stuck at the spinner. (Steps: Navigate to https://tweetdeck.twitter.com/ and log in.)
LessWrong: Site disappears after a moment. (Steps: Navigate to https://www.lesswrong.com/ )
Google web apps: Can't log in; after picking account password box doesn't load. (Steps: navigate to https://gmail.com/ and attempt to log in.)
Reddit: Can't vote on posts, collapse comments, or expand posts. (Steps: Navigate to https://www.reddit.com/ and attempt to do any of the above.)

Expected results:

Facebook: News feed should load.
Tweetdeck: Site should successfully start up.
LessWrong: Site should not disappear after loading.
Google web apps: Password box should load
Reddit: Should be able to vote, collapse, expand

Is this the Firefox from the Mint repository, or the Firefox from firefox.com.

If it's the latter, a quick check would to be download Firefox 70 from firefox.com, unzip it, run the binary and see if you can reproduce the problem.

If you can't reproduce the issue, then the problem is with the Distribution's build and you'll have to file an issue with the maintainers.

If that turns out to the difference, then I suggest setting up Firefox on your desktop. I don't know what the recipe for that is in Mint, but in Ubuntu I install firefox to /opt/firefox and use a desktop file.

This is from the Mint repository. Haven't yet checked with direct download.

Here's the nightly on Linux UA string: "Mozilla/5.0 (X11; Linux x86_64; rv:72.0) Gecko/20100101 Firefox/72.0"

Maybe those sites are doing UA sniffing which is breaking things?

do thing work better when you test it in firefox private browsing mode?

OK, finally had a chance to try the above suggestions.

  1. The direct download works fine. So this is indeed just a problem with Mint's version.

  2. That said, I also think it's worth noting that indeed things work just fine in private browing mode! Thanks for the suggestion!

Anyway, I guess this is actually a Mint issue, so I'll go report it to them. Thanks.

Thank you, Harry.

I'm going to resolve this as MOVED. When you know the URL for the issue in Mint's bug tracker, would you update this bug with it?

I submitted it to: https://github.com/linuxmint/linuxmint/issues/157

I think that's the right issue tracker based on the docs I found; we'll see if they move it somewhere else, I guess.
