I regularly use the backspace key to go back a page. I have always had about:config for this function set to 0 which is supposed to allow this. But, it seems some websites prevent the backspace key from functioning (it does nothing). I am using the latest available version of Firefox for Vista.

How can this be fixed?

FF 66.0.2 64 bit Windows 10

PROBLEM WITH CHANGING THE "SEND WEBSITES DO NOT TRACK SIGNAL."

I realize that most FF settings do not require a restart of FF to take effect but it seems that when changing the "Send websites a 'do not track' signal from "Always" to "Only when Firefox is set to block known trackers," the effect of doing so is not apparent until FF is shut down and restarted.

The issue is that no prompt is given after making this change. There should be a prompt.

Recently I have been unable to load videos on a site I visit regularly. After a lot of messing around with the security settings I finally discovered it was sending this do not track signal that was causing the issue. However it took a ridiculous amount of time to narrow the issue down to that one setting since FF was not giving me any indication the browser should be restarted after making the change. It was only my suspicion that led me to try changing the setting and restarting that i finally discovered how to fix the issue.

There is NO issue with switching the setting back to "Always." That takes effect immediately without restarting (videos instantly become unplayable). When switching the setting back to the second setting, the videos don't become playable again until FF is restarted.

IMO, there should be a prompt when choosing the "Only when Firefox is set to block known trackers" setting to restart FF so the setting actually takes effect,

OR, fix the issue so FF doesn't have to be restarted.

Either fix would be better than leaving users in the dark.

I think FF has done another update to 66.0.1 (64-bit) OS10.11.6 and now Logging in to secure websites like Santander and Youtube just hang. I use 1Password and Command\ doesn't work on this Mozilla site for instance. Plus as FF is my default browser clicking a WeTransfer link in an email has stopped working and just hangs in FF. My Add ons (which I've been using for years in some cases) are 1Password, Adblock plus, DuckDuck Go, I Don't Care About Cookies and IBM Security Rapport. Out of interest, why does FF need to keep producing such regular updates? It's a great browser but it seems each update comes with its own set of problems.

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.

I use Firefox v66.0.2 on Windows 10 Pro and on my weather website that has Flash links to external sites to display the Moon's phase and World City Times the placeholders to populate that info has become very slow indeed. It can take well over 40 seconds to show the times.

Using the same version of Firefox on a Windows 7 64-bit PC the data displays in seconds. Using Microsoft Edge on Windows 10 it's also very quick. Only Firefox / Windows 10 seems to be the problem.

I have tried resetting things but to no avail. It's been like this for a couple of months now. My website has been unchanged in years. http://www.cheadlehulmeweather.co.uk

Can you assist please?

Sending laptop in for warranty, question about backing up Firefox

Hello,

I have an Acer laptop that I'm about to send in for a warranty repair for several different issues. I was told by Acer that it will likely be reset/reformatted upon arrival. Also, I was informed that the laptop may be replaced with a completely different unit at their discretion.

I would like to obviously keep all of my Firefox info, history, bookmarks, etc. and be able to restore them to the computer when it is returned to me, be it the same laptop or a new one.

Can someone please instruct me on the proper way to do this?

Is it as simple as copying my Profile folder to another drive, and then reinstalling it after I reinstall Firefox back on the laptop (be it my original one or a new one) when it has been returned to me?

Do I need to use the Profile Manager?

I bought a used Lenovo to use while my Acer is in for repairs. Today, I think that I successfully synced the two of them. (I have a Windows phone and thus no Firefox app for my phone, and could not enter a phone number to "complete" the sync as instructed) but it seems to have worked.

Will the bookmarks, history, tabs, etc from my Acer disappear from showing up on the Lenovo when the Acer laptop is reset by the factory?

(Or should I even delete Firefox from that Acer that I am sending in just out of privacy/security concerns?)

Thank to any and all who can assist me with doing this correctly. I apologize for any ignorance on my part, I've just never had to send in a unit for repair before.

Thanks, Chris

I have periodically gotten a screen that fills the entire browser window that is dark, somewhat transparent, and contains only the word CONTINUE with an X in the top right corner. The screen tends to appear when performing a Google search. Unfortunately I do not (yet) have a screen capture. Firefox is version 66.0.2.

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)

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

if Firefox is running and i click on a link in my email, Firefox will open a new tab and show the page. if Firefox is NOT running and I click on a link, Firefox will open a blank tab; I'll have to click the link again - without closing Firefox - for the page to show.

this behavior is fairly new - about 4 updates back.

Over the last two days (March 27-29), I have been having a damn battle over Bookmarks. What have y'all done to them? Duplications. Bookmarks out of the folders. I gave up trying to clean up the mess so I deleted most of what I had. THEY KEEP COMING BACK...ALL OVER THE PLACE. Blank folders. Random bookmarks showing up in categories I didn't place them in.

What is WRONG? Make it stop!

Every time you guys update something, your break something else. Sometimes, it's just TOO MUCH.
