This problem appears on MacOS 10.13.3 but NOT Linux Mint 19.3 (Tricia).

Repeat-by:

1. Start here:

       https://www.cnn.com/

That page should load cleanly.

2. Now click on "Live Updates", which is the top entry in the middle column of that page, and as of 3 April 2022 11:20 AM EDT takes you to:

       https://www.cnn.com/europe/live-news/ukraine-russia-putin-news-04-3-22/index.html

On MacOS, that page loads and is momentarily visible; then the page/tab it's loaded in goes blank. On Linux, that page loads as expected and remains visible.

Notes:

The problem did not happen with Firefox 88.0.1/MacOS.

The problem does not happen with Firefox 98.0.2/Linux, i.e., it appears to be specific to MacOS.

The problem remains whether extensions are enable or disabled (one a time or all at once).

The problem remains after the cache has been flushed and pages have been reloaded.

The problem remains after Firefox has been (completely) shut down and (cleanly) restarted.

The problem does not happen with Chrome/Chromium on either MacOS or Linux.

The problem also happens on *some* other pages on CNN's site (but not all) and on *some* (but not all) pages of other sites but there doesn't seem to be a pattern that explains which URLs exhibit it and which don't. This suggests that it's not privacy settings or extensions or anything like that, because there's no reason for those to vary from page to page within any one site.

If I'm VERY fast on hitting the "X" that stops a page loading/rendering while in progress, and I get the timing just right, I can catch it before the page/tab goes blank. So it appears that Firefox is in fact fetching all the content and can render it, but then for some reason is blanking the page/tab once that's done.

The attached screenshot shows what the problematic page (from step 2 above) looks like on Linux. On MacOS it's blank, so I didn't include a screenshot of that.

Hello, I have the question while using Firefox.

When I browsing the websites via Firefox, I found that Firefox uses two groups in keyshare(x25519,secp256r1), while other browsers use single group(x25519) in the keyshare. So I tried to find where I can set up keyshare part in my Firefox, but I cannot find it.

Can you explain where can I find the setting for the keyshare in the Firefox?

Thanks!

Which Mozilla version is the latest which includes ((update options )) I still use windows 7 32 bit My system is not compatible for 10 The new version makes trouble with window 7, so I uninstalled It goes crashing when opens I read many topics using old version does not solve the problem For me it solves When I install new version ( 90 or newer ) it shows black screen when opens But with old versions, it does not show --- Now I tried 75 it contains option but the update still runs though I have chosen Check for updates but let you choose to install them

Hello, I have encountered a lasting issue: Firefox' telemetry collection process causes a cmd window to pop up briefly. The windows sometimes lingers a split second later, and if I accidentally click it at that time, whatever program I'm in will get minimized and I'm back on the desktop with cmd window at front. You might want to have a look at that, I disable my telemetry for time being. Firefox version is 99.0.1 (64 bits), operating system is Win10 10.0.19043. Respond for other data you might need. Best, Michal

A subscription service I purchased (Kine Mania TV) has on several occasions gone to a porn site. I have enjoyed many hours of wholesome TV series and movies at Kine Mania TV - but HATE it when smut shows up instead! Please advise - this is scary stuff for an old lady. I took screen shots of the web address if you need me to provide. Nadeane Mannion

Hackers will be very happy now that Firefox automatically download their malware and backdoors. Thanks to Firefox, hackers will be able to infect millions of world computers and install ransomware and make havoc i financial, health, and other industries. Firefox will forever be praised by cybercriminals of the world.

something new-- I can't sign in to my att account like I always have. I can still log in on older win 7 and android devices. Only this win10 desktop is now having problems today. Any suggestions?

I searched for an official portable version of firefox and one of the first results was this https://support.mozilla.org/en-US/questions/1247235 anyways this seems dissapointing since he says we should only download from official sources and at the same time there is no official portable version, can i be honest.. this sucks. You know time passed since that thread was created (3 years...) but still no offfical version, why?

So it seems to most known source for firefox portable is this site: https://portableapps.com/apps/internet/firefox_portable I know you don't represent this website but still i have to ask how secure is it?

Also, how are chances mozilla will work on a portable official version? any plans?

I use Kaspersky for my internet security. I choose the 'Safe Money' option for many other sites...but cannot connect sign on with my bank. Because the page always comes up asking for me to choose a browser. I down load and update the firefox site. This does nothing except giving me multiple firefox updates! What is happening and how can I stop having this issue pop up? The other sites on 'Safe Money' are not banking sites, but still need security. Do I have to change browsers? I can be reached at [email removed from public]

Thank you for any help in this matter

with firefox, drag and drop for attachments is not working using macOS High sierra, and outlook emails. It works ok in Chrome but I dont want to change over. I deleted cache and cookies and restarted. It worked ok for a while but stopped working agaiin.

Firefox is still automatically downloading files to a default directory, even though I have selected "Always ask you where to save files". This is a security risk. I want to be asked BEFORE the file is downloaded so I can choose the location or choose not to download. Thanks...Jim.

All my bookmarks on my toolbar vanished, even though they're still listed as being bookmarked on the toolbar, and the toolbar itself is still present. Only around 2 or 3 times have they actually shown up within the past month or so with all of the times I start up Firefox. What's the deal?

When I try to log on to hmnow.com, all I get is a white screen. I worked with Hallmark support, but they couldn't figure it out even though I have a paid subscription with them. I've rebooted my Mac and it says I have the latest Firefox version installed. This has gone on for weeks. I've had no problem with any other website.
