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 (when I googled the error message, I got a lot of outdated advice from previous versions of Firefox)

HTTP Strict Transport Security prevents me from accessing a server that I'm doing development on

I cannot access a clients site that I'm working on due to an HSTS error, I used to be able to bypass this with test.currentTimeOffsetSeconds, however it seems to not work anymore.

I use Firefox for development because it has better tools than any browser I've use in the past, however this is a real blocker for me, since the sites I'm working on don't have DNS names yet and can't get updated certificates till then.

I've also manually added an exception in the certificate options, though that also didn't work.

Please guys, I've always been pushing people to use Firefox, though if it starts limiting my options without any way to bypass it if I feel I need to do something, then I'll be forced to go hunting for a browser that gives me more freedom, not to mention this is costing me work hours.

I know this has probably been asked before, but none of the solutions really work for me. Playing Youtube or other video on sites like Vimeo result in choppy playback. I have ruled out hardware problems, because playing local video works fine. This issue also occurs on Chrome, and turning on or off hardware acceleration does nothing.

Thanks for any help in advance.

HERE IS THE ANSWER Here is the answer to get TABS BELOW with Firefox V90 . . copy all of this code below the broken line into your - userChrome.css - file and save it. You can modify the 45px in this line if you wish to get an appropriate height . . just experiment with different numbers till you get it right --menubar-height: 45px; /*30px|41px=11px; caption buttons on menubar*/

Also to make the tabs wider or narrower, modify the line which is coded width: 50vw !important;

Finally you must enable - css - in Firefox, by typing about:config into your address bar, and search for toolkit. When all the toolkit options appear change the one which says toolkit.legacyUserProfileCustomizations.stylesheets to TRUE by click the icon in the right hand column. Than close Firefox and reopen, and check how it looks This will enable your - css - file to be read, and interpreted and accepted by the Firefox browser.

I updated to Firefox 22 today and since then Firefox opens in the tabs from the previous session instead of my home page. This occurs no matter how I close Firefox. I am aware that this has happened in previous versions of Firefox(e.g. Firefox 20) and that a solution would be found in a future version. The solution has obviously not been found.

I have applied the suggested workaround, changing the preference for browser.sessionstore.resume_from_crash to false, with absolutely no effect. This workaround did work in versions 20 and 21.

Can anyone help?

I am using Video Download Helper with companion app, when downloading videos, the DownloadHelper will uses only one process of Firefox with very high CPU and memory usage. . Ans cause it does not take advantage of all the CPU cores it is very slow, and uses high memory for that process and will make all tabs in Firefox slow.

It seems that this process is the core process for Firefox, although it is a sub-process. It is the process that almost doesn't uses GPU memory.

When finished, if I killed this Firefox process to clean memory, cause it will just accumulate the memory in that specific process, all the tabs in the Firefox will crash and can't be refreshed, until I close Firefox and open it again.

Usually when I kill a Firefox process that is not responding, it will crash a few tabs and they can be refreshed after that.

Is there anyway that can make the companion app uses all processes for Firefox, so it will distribute the CPU usage to all cores, and if used a high memory it will be distribute the memory to all process and will be easier to clean.

I upgraded from Windows 7 (where FF worked fine) to Windows 8.1 a few months ago. After the upgrade FF stopped functioning well enough for me to use. I switched over to Chrome/Opera but I'm tired of those and want to come back to FF but am finding it very hard. The issues are

- I can't copy/cut anything via either Ctrl+C or the context menu. The context menu rarely will show Copy/Cut/Paste and if they are shown they do nothing. One time I pressed crtl+C a lot ina row and Copy worked for that session but when I restarted the browser it stopped working again. 

These may or may not be related the copy/cut issue but certainly are not working as well.

-  Sometimes the context menu will show every possible menu item ever available in the OS. I'll right click and I need to scroll and scroll to find copy/paste. They still don't work when I find them.
- I can't highlight text and have the context menu show the "search google" button. Nor can I take that highlighted text and drag it to the URL bar/search bar.
- If a video is playing (youtube/comedy central...) and I drag that tab out to make a new window this creates a blank "New Tab" in the original window and make it look like the video tab is moved to a new window but the video won't play any more. Nor can I stop it. and I can't close that tab by right clicking. But I can Ctrl+W it but that doesn't stop the audio. The audio will continue until I close FF entirely.
- Middle click used to not work but now usually works. i.e I used to not be able to close tabs or open links in new windows with middle click. But FF 28 seemed to fix that. Again mayeb/maybe not related.

I'm currently running FF 29 but these issues were all present for the past ~4 versions at least (whatever was out last fall). I use FF sync and everything works fine on all my synced devices which run W7. This is the only computer i have W8.1 on so I can't test another 8.1 setup. I've uninstalled and reinstalled a few times but I don't think I've removed all my personal setting from the computer. I have some extensions (Adblock plus 2.5.1, All-in-one genstures 0.26, Rainbow 1.6, Smartest Bookmarks bar 1.11, Stumbleupon and TiddlyWiki 1.0alpha18). These are all also synced on my other computers.

Any ideas?
