Firefox 89.0.2, windows 10 pro with latest updates

I had trouble with two sites - they were displaying the mobile view instead of the desktop view. I looked at the 'general.useragent.override' string in about:config. It was set to "Windows". I changed it to Mozilla/5.0 (Windows NT x.y; rv:10.0) Gecko/20100101 Firefox/10.0 and then the sites displayed correctly.

But now, duckduckgo and google are displaying strangely (perhaps they are showing the mobile version of the website?? Beats me.)

There are 3 other useragent config variables in about:config  : dom.push.userAgentID 66cb7374724c47149c50bf2c98c7f97c general.useragent.compatMode.firefox false useragentswitcher.version 0.7.3

(Plus, there are 4 'devtools' variables.)

Are those correct? Am I missing some? What else should I look at in order to fix duckduckgo and google?

Thanks!

PS: duckduckgo and google display correctly in Chrome. But I do not want to use Chrome.

PPS: I uploaded screenshots showing what google looks like on Firefox and on Chrome.

HTML5, YouTube, and Netflix video playback does nothing

Playing HTML5, Youtube, or Netflix video does not work at all for me - Netflix throws an error code, while Youtube and HTML5 simply never stop loading.

I've tried

• Starting Firefox in Troubleshoot Mode
• Clearing the cache and cookies for the given website
• Refreshing Firefox

On the chromium-based edge browser, video playback works normally.

DRM-controlled content playback is enabled, hardware acceleration is disabled, allowing auto-play doesn't help, and neither does disabling Tracking Protection.

Since three updates ago there are white bars on three sides of my Firefox window whenever I disable the title bar. (The bars should be visible if you open the first picture I've attached over a coloured background. The second picture shows the bars disappearing when the title bar is switched on.)

This problem persists in Safe Mode and even after a fresh installation of Firefox, so I am confident that my add-ons and themes are not the issue. The bars also show up when using the Firefox default theme, so a custom theme is not the problem either.

I have also tried, to no avail: Updating my graphics driver, changing my screen scaling, cleaning the registry. And of course simply restarting my computer.

I am at a loss as to what the issue is or how I can fix it.

Hi,

I keep getting the "Secure Connection Failed" error message on Google websites (search engine, Gmail, Agenda, Meet, etc.). Usually I can first access the website fine for while, but after a few minutes I get a "you're offline" popup and refreshing the page gives the error. Sometimes I get the error right away.

I've seen many others ask that question, and I've tried this: - enable/disable ocsp stapling - enable/disable HTTP3 - empty the cache

Some other facts : - There is no additional info on the error page (it's not one of the "SSL version unsupported" or "Add an exception" pages) - I'm on Windows, with the latest Firefox version (although this problem has been going on for a while) - The only antivirus is Windows Defender - I'm not behind a proxy or VPN - This happens at work, and at least 3 of my colleagues have the issue - It sometimes happens on non-Google websites, but very rarely - Firefox for Android works fine on my phone on the same WiFi network

I appreciate any help in resolving this, it's getting to the point where I have to use Chrome to work.

Cheers,

I saw (apparently) the same problem documented in |an old issue an old issue, but the issue's marked closed at this point. I'm seeing new tabs fail to load, but if I take exactly the same URL and paste it into another tab, it loads instantly...thus, every other tab isn't loading.

In reality, this isn't happening with every new tab, and it definitely goes in spurts, so when I start seeing this, it happens for most tabs; otherwise, I can go for hours with no problem. Typically, if I leave one of these hung tabs long enough, it will eventually (minutes later) load.

This is happening on a newly-built PC with a weeks-old install of Firefox. Any idea what might be amiss?

Hello My Firefox browser stopped working suddenly. I used it this morning (11/12/21) without issue but when I tried it around 6PM CST US I got PR_CONNECT_RESET_ERROR on everything I tried to load. There was no updates that I am aware of and I tried all of the solutions provided on sites I visited up to and including disabling anti-virus with no success. For now I've uninstalled the product until a solution has been found. Thank you to anyone who may be able to assist in this problem. All other browsers I've tried work as expected.

Hi Customer Support!!!

I have been using Firefox for a long time but never faced this issue. The problem is that when I try to open the browser, it crashes every time. I have searched on YT and google but everyone says, remove the firefox program and reinstall the firefox, but I have many important data in browser and I don't want to lose the all logins details by removing it.

Can you please suggest me any alternative solution for it without losing any data?

Regards, Weyek

My browser updated to 96.0 (64-bit) about an hour ago. I've been running the Cheshire cat Theme for a long time now without it making the entire browser turn Dark (I just like what it did to the Tab bar and the Menu Bar). It didn't effect anything else -- not the Menus themselves and certainly not any webpages. But since the update--the Menus, the Firefox Home page, the Settings page, and even the Google search results pages--all have been showing up in Dark Mode. I switched around other themes I have and noticed that only the themes that are light in color stop everything from going dark.

It's a minor thing but I would really like to keep my set up as it was. I would really appreciate some help.

Hi, I would like to join the chorus and say that the unified extensions button really needs to be fixed somehow. I can't stand it -- it slows down my workflow and seems like "change for change's sake".

But if you guys are serious that it can't be removed for some reason, then at least PLEASE make the unified extensions thing something that can be expanded horizontally along the toolbar (instead of just being a dropdown list) with preferred / most used extension icons visible in it, so that instead of

>clicking the unified extensions thing >scrolling down to find my extension >right clicking on the extension >choosing the option I want

It will just be

>click on the extension icon in the special unified extension section of the toolbar >the options for the extension pop up and I can choose one JUST LIKE THE OLD WAY THAT WAS EFFICIENT

I wouldn't even be opposed to an entire Extensions Toolbar with super security or whatever built into it. As long as the icons are still conveniently located and accessible!

I have a bunch of extensions that I don't need to interact with regularly, like my adblocker, https everywhere, or the thing to make webpages appear in dark mode. But every time I click the unified extensions thing they're right there at the top of the list. My screenshot extension however (for example), which I use constantly, is somewhere hidden near the bottom of the list, so I'm constantly scrolling down awkwardly looking for it. It used to be one button click to take a screenshot, now it's like five or six clicks and takes around 20+ seconds every time. IT'S VERY BAD USABILITY DESIGN. It might "feel" cleaner or more organized to put everything in a list, but it's not as functional for the end user (in my opinion).

Please reconsider your design of this thing and investigate the possibility of keeping certain extensions visible on the toolbar somehow to remain easily accessible to the user. Hopefully I've been able to explain my concerns to you. Anyway, I still love Firefox on the desktop, but if you guys can fix this that would be great.
