We have a page that showes total work times of employees on a timeline which holds data for one year. This totals in 106219 nodes on that page. Previous versions of FireFox did not had issues with this, other browsers (Opera, Chrome, Edge) have also no issues and render the page in about 2 - 3 seconds. Not so Version 90.0.2 (32 bit). It now takes 4 minutes to render this page completely. Trying to debug this is impossible cause during rendering the browser is not responsive at all. Is this a bug that sneaked in or what can we do? This happens on fresh installs of Windows 10 with fresh installs of FireFox, that said it's not something that could be reset or cleaned etc. Any Ideas as to why FireFox struggles now with above mentioned number of nodes as oposed to earlier versions?

RSS feeds broken - content security policy issue?

Since I upgraded to Firefox 90.0, my RSS feeds can not longer be refreshed in my feed reader. I get a 403 error ("access denied"). When I check the debug information on the URL, it says:

Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”).

I am using Feedbro on Firefox 90 on Ubuntu 20.04 on two different computers, and getting same problem.

Clearing the cache, trying other feed readers, deleting cookies etc do not help.

A sample feed URL: https://news.google.com/rss/search?hl=en-US&gl=US&q=mozilla&ceid=US:en In Firefox, I can open a tab and see the text file. But Feedbro, or any other reader, cannot detect the feeds on this page any more.

Any advice? I absolutely rely on RSS feeds for my work.

Thank you kindly!

I'm out of tricks here. Last night I updated Windows on my desktop (Windows 10) and after several hiccups and restarts the computer is operating correctly...except for Firefox. The browser window opens normally but clicking on any bookmark or typing a web addy manually does nothing...it just stays blank. When using a bookmark, no address propagates to the address bar. In an effort to fix this I have done Firefox refresh (a few times now), run Firefox in troubleshoot mode (a few times and at least once this caused Firefox to crash), uninstalled and reinstalled Firefox (twice, second time WITHOUT saving prior account settings), restarted computer and uninstalled adblocker.

Absolutely NO change from any of this. My laptop (Apple with Firefox) works fine and the desktop WILL browse just fine on MS Edge, so this is not a connectivity problem. Any ideas on fixing this would be greatly appreciated. TIA

When I launch Firefox, if I press anything or wait for a bit, the program stops responding and I have to force close it. Firefox was working just fine until recently. I have not updated Windows or made changes to Firefox prior to these issues occurring either.

I have tried following this thread: https://support.mozilla.org/en-US/kb/firefox-keeps-crashing-startup#w_try-a-clean-install_2

I am not able to start in Troubleshoot mode as I cannot interact with Firefox in any way.

I also have trouble with doing a clean install. When I run the uninstaller, it eventually gets stuck and I have to force close the uninstaller. After closing the uninstaller, I deleted the Mozilla folder under C:\Program Files and the Firefox folder under the %appdata% directory.

I then tried both the stub installer for Firefox and the full installer located here: https://www.mozilla.org/en-CA/firefox/all/#product-desktop-release

Both installers get stuck. I have attached an image of where the full installer gets stuck. After force closing the installers, I am still able to open Firefox, but it has the same issue of not responding.

I have also tried creating a new profile with the profile manager, but the issue persists.

If anyone has any ideas or knows of a solution, please let me know.

Thanks.

For the last couple of months I've been having an issue with Firefox freezing when I bring up a news article on Yahoo. It only happens when there is a video attached to the article, the video and the text of the article won't load. After a few minutes there is a message saying "This page is slowing down Firefox. To speed up your browser, stop this page". All of the Yahoo news articles work fine when I bring them up in Chrome. How can this be fixed??

When I am in an open page in Firefox 90.02 and try to open a link MOST OF THE TIME It will post the error message below and not let me proceed. I can tell from other posts that this is not uncommon, but I cannot find a posting that is useful.

Thus far I have 1. reset/repaired Firefox 2. ensured that Firefox has full access to my computer and the internet and that the Firewall is off. 3. reset all the security and privacy settings to the lowest settings or turned them off including pop-up blocking, tracking, really all settings, cleared the cookies and caches.

Several websites I use frequently, including Facebook, the Macquarie Dictionary and even Mozilla's own support website, don't work properly with the new version of Firefox. I even had to use Google Chrome to access this support page, as I couldn't get past the login page using Firefox. When I first opened the new version, Firefox told me that I had to enable cookies for it to work. I went to Preferences and checked that cookies were definitely enabled. I quit and restarted both Firefox and the entire computer, checked that cookies were still enabled and it still doesn't work. Why is this happening? I don't want to change my default browser permanently, but I need it to work for me. Can anyone help?

I am getting more & more frustrated and exasperated, as simple browsing has become tortuously slow, with many sites taking forever to load, or only partially load, or have to be refreshed a couple times, to finally get it to load. And videos constantly freezing up, despite lots of free RAM, and a very high-speed internet connection. I assumed whatever was causing this would've been addressed in the last update, or two, but no, it's only getting worse.

(I'm using a desktop with Windows 10 without the recent disservice pack update.)

This issue is a recent development, even newer than the weird sans serif font issue that began with Firefox 90. The issue is intermittent.

When I scroll down a page using the wheel on my Logitech M510, parts of the page will refresh at different speeds. Usually this is noticeable as the illusion of a diagonal line and disappears as soon as scrolling stops. Sometimes part of the prescrolling display will remain rather than changing with the rest of the screen, usually as a rectangle. I've also started getting only partial display of dialog boxes when editing in Wikipedia, in which only part of the image changes.

The rectangular area not updated is usually near the centre of the screen. The Wikipedia box issue has the opposite issue - the only part of the box that appears is in the same spot that fails to refresh when scrolling.

If I tap on an arrow key, the unrefreshed portion of the screen gets back in sync with the rest.

The issue seems unrelated to website, occurring on Wikipedia, Facebook, and Google.

I disabled the Proton interface within a week of its appearance because it wasted so much vertical screen space, if that's any clue.

For about a month, google products on firefox randomly stop working.

- I get the "Oops...error #001" in gmail, when i reload it just continues to get an error cycle until eventually it goes to network protocol error.

- Google search randomly does not work at all in the url/search bar, and once it doesn't work the tab is useless. Putting in another URL and hitting enter it appears to have loaded but of course nothing has changed.

- I have no extensions installed.

After latest update to 90.0.2 I'm no longer able to log in to an internal corporate website. This has worked fine before. Accessing the same site with Chrome or Edge still works fine but no longer with Firefox.

Error message: SSL_ERROR_CERTIFICATE_UNKNOWN_ALERT

I have previously struggled with Certificate with Firefox but after enabled security.enterprise_roots.enabled in Config it has worked fine until now.

So what has changed this time and how to bypass? Obviously the cert/website works fine with other browsers.

Thanks Henrik
