Fóram Tacaíochta Firefox

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.

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.

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.

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.
