After I switched to Firefox 59 beta on Windows (7 upgraded to 10), I see the following issue all the time. When accessing finance.google.com in one tab and etrade.com (internal page) in another, if I am on finance.google.com and if it refreshes and is slow for some reason I start seeing a blank page with a spinner on that tab and while this is happening, if I switch to the etrade.com tab, I see that page is blank too and has a spinner that doesn't refresh until the finance.google.com tab comes back -- almost like the browser is stuck in a system call somewhere and all tabs using javascript are blocked. Maybe it's likely some interaction with some addons I have (mostly NoScript), but it's been frustrating and for the first time in so many years I am considering switching browsers :-(.

BTW, where is the best way to ask about issues like this regarding Firefox, it seems like Googling for Firefox issues mostly only brings up years old issues and no one is publically posting about more recent issues like this. Also it's hard to describe problems like this in a reasonable way to come up with search terms that Google likes and doesn't hit old reported problems.

Not sure it's related but a lot of Google's sites are terrible on Firefox and Edge. IIRC they are using polyfills for some heavy stuff (if you assume no malice, that's probably the cause of many problems).

Try using safe-mode https://support.mozilla.org/en-US/kb/troubleshoot-firefox-is... or maybe creating a new profile. The beta versions, just like Chromium or Chrome, occasionally have some weird bugs. At least for me most of them are always hardware acceleration related.

I've had trouble accessing the Google Analytics dashboard(s) in FF as well. Nothing gets rendered except the background gradient.

In the interest of not using Chrome though, when I run into such issues I use Brave as it's Chromium-based and thus allows me to side-step those problems.

The times I had problems with GA was because of some uBlock rule or weird A/B tests (I assume) or caching, clearing cookies and site data fixed the problem.

I have this exact issue, and I really don't think it's google's fault. Both those sites are using canvas to draw charts. I experienced it on crypto trading sites mostly. Try a fresh profile, copy your bookmarks and history over to the new one. I did this and the problem was gone. (See my other comment in the thread)

The #firefox channel on irc.mozilla.org is a good place to start:

And the Firefox subreddit is pretty active:

Firefox uses a limited number of content processes (I think the default is 4? Might depend on your hardware). So if both tabs get assigned to the same process, one tab freezing up means you can't use the other tab at the same time. Check under Options -> Performance to see if yours is set to use only one, or not to use separate content processes at all.

I've also noticed the same blank page with spinner (which seems to hang and never actually refresh in my case) on non Google sites since the quantum upgrade. Figured it was a bug that would get squashed in a subsequent version, but no luck yet.

Google web apps and sites don't work well in Firefox, generally speaking.

Examples where Chrome performance and functionality is superior include:

- Inbox (try downloading attachments) - Maps - Analytics - ...

The only times I got issues with this on Firefox was due to some add-on (Disconnect for instance). On Firefox out of the box I haven't had issues with downloading attachments lately, even with the add-on on.

Maps work fine for me (Dev Edition here though).
