After updating to Firefox 66.0 on MacOS 10.13.6 today, websockets on my localhost stopped working.

When using Create React App (version of "react-scripts": "2.1.8" => "webpack-dev-server": "3.1.14" => "sockjs": "0.3.19"), hot reload is broken and I get following error in the console:

`The connection to ws://localhost:3000/sockjs-node/743/khw0phgj/websocket was interrupted while the page was loading.`

When I tried https://www.websocket.org/echo.html, it works fine and no problems with hot reload in Chrome 72.0.

How can I debug and fix this problem please? (when I googled the error message, I got a lot of outdated advice from previous versions of Firefox)

I am running Firefox 52.9.0 (32-bit), Win XP PRO SP3 on several computers and only my desktop has this problem.

Youtube videos embedded in other pages do not work and only blank space is displayed but if I go to Youtube the videos play correctly. This only happens in one computer. In other computers running same Firefox 52.9.0 (32-bit), Win XP PRO SP3 this problem does not happen.

I guess it might be some configuration problem.

On many pages (commercial), when I click a link to look at another page, clicking the "Go Back One Page" button results in the original page scrolling down a varying amount.

For example, I visit CNN.com. I then select an article I want to read. When reading is complete I press the "Back" button, which returns me to the original page, but also scrolls that original page, sometimes just a few lines, but also sometimes to the very bottom of the page.

This only happens on the newest (66.0) version of Firefox upgraded yesterday. It does not happen with other browsers. It does happen with Firefox started in safe mode. I also checked the carat (^) scroll in "Options" and this was not selected.

This also happens whether I use the Firefox Page Back Button, or the "Back" button on my mouse.

Thanks Doc

please help i am panicking so much right now i would type in all caps but i know that wont help

my session has a very very large amount of tabs and it only just started slowing down in the past 24 hours. ive never had trouble before today, but i just restarted and it only loads a completely blank page with the tab name New Tab

there is no option to restore previous session, and both restore closed tabs and restore closed windows options are empty in the library section

ive opened 2 windows and refuse to close either because im afraid it will completely remove all of my tabs forever. i will only restart in safe mode if i get a really good explanation and reason. anything that sounds risky i would really need a good explanation before i do it please

ive done verify integrity in the about:places section i think its called. ive looked around for my problem and ive submitted some recent crash report which could've been when the browser lag started

Thank you

It's really annoying trying to close a tab only to open a new one again because you middle clicked on the empty portion of the tab bar.

make everything dark in firefox

Hi, I'm trying to get as much as possible of firefox to use dark theme to save my eyes at night.

I use https://addons.mozilla.org/en-US/firefox/addon/darkreader/ to customize the sites automatically and it does an excellent job, except that firefox pages can't be customized with it and by that I mean:

about:blank about:newtab about:config about:preferences

for the blank and newtab pages I found three solutions:

1- create a [userContent.css](http://kb.mozillazine.org/UserContent.css) file with the following

@-moz-document url-prefix(about:blank) {*{background-color:#000000;}}

@-moz-document url-prefix(about:newtab) {*{background-color:#000000;}}

2- go to about:config and change

browser.display.background_color to #000000

browser.display.foreground_color to #ffffff

3- Go to "Preferences" and search for "colors" click on the colors button and set the background and text colors to the same colors as in 2.

now I tried all of the solutions above and all of them have side effects, the most prominent and annoying one is flashing white page for a couple of seconds when opening a new tab or white page while the website, other annoyances is that the settings don't apply to about:config and about:preferences even if I add them in userContent.css

-To test the flashing white you only need to open a new tab (while applying my settings above) and you will see it.

-To the white page before the site is loaded you need to open the link from another page(if you open a new tab and then paste the link you won't get the white page since the about:blank or about:newtab will have the dark background)

so to see my problem do the following:

1- go to https://github.com/biesiad/deelay#deelayme

2- right click on deelay.me link and click "open link in a new tab"

the link will be opened in a new tab that has the background in white or grayish color.

How can I solve these problems ? any tip would be appreciated.

Regards

I was having troubles with the Cinnamon desktop and had to switch video cards. I found Firefox crashed right away. I then replaced the video card and reloaded from scratch and the Cinnamon desktop works fine but Firefox still goes straight to crash report. In fact I tested and even Thunderbird goes straight to crash report. It does appear to send out the info and it created a report but I can't do a copy and paste of the report since I can't send anything out myself. The version that came with the Linux Mint 19.1 Distro 32 bit should be a 32 bit version. Both Firefox and Thunderbird is working fine on my other two 64 bit machines running Mint 19.1 64 bit.
