Ondersteuningsforum voor Firefox

Hi all,

I am trying to customize my Firefox on Mac because the tabs on top interfere with the menu bar, thus I only want tree-style tab extension to work on the side, with the tabs on top disabled.

I followed this thread: https://support.mozilla.org/en-US/questions/1184674#answer-1028260 as well as this clear guide on how to create userChrome.css: https://www.userchrome.org/how-create-userchrome-css.html When I tried to restart the browser, I seemed to have been logged out of my profile, with all customization gone and a standard white (instead of black) menu. I deleted the chrome folder and it is normal again now.

I suspect the userChrome.css file should contain more than just the one line I tried to add: #tabbrowser-tabs { visibility: collapse !important; } ; Is there any location where I can copy my current intra-browser customization into the userChrome.css file?

I am building a website and, for the last couple of days, when I make changes to the CSS file they are no longer being picked up by the browser by which I mean they aren't displayed in the web page nor in the developer tools inspector.

They are visible in Chromium browser and dev tools.

I have cleared the cache and refreshed the page to no avail. It is only when I restart the browser that the new style rules take effect in the browser and show up in the dev tools.

I 'refreshed' firefox as suggested. The guidance suggested that all my logins and passwords would be preserved but when I check the Logins and Passwords all have been cleared. I am now faced with the arduous task of resetting many many login credential. Poor advice from Mozilla.

when trying to access my outlook account after successful authentication I get a "failed to load javascript" error. Prior to last browser update (last time I checked mail on pc) everything was working fine. Firefox 79.0 64bit Windows7 home premium sp1. here the complete message: cId: 7810C50E8ED44602A6386E7A8AAD79A3 app: Mail st: undefined reqid: undefined wsver: undefined efe: undefined ebe: undefined et: ClientError esrc: Script err: Error: Failed to load javascript. estack: 39/_</t.prototype.onLoadFailed/</<@https://outlook.live.com/mail/0/?bO=1&sessionId=ec7c7ede-b5d1-490a-be29-837f0b75644a:351:57463 u/</<@https://outlook.live.com/mail/0/?bO=1&sessionId=ec7c7ede-b5d1-490a-be29-837f0b75644a:344:2574 u/<@https://outlook.live.com/mail/0/?bO=1&sessionId=ec7c7ede-b5d1-490a-be29-837f0b75644a:344:2679 l/<@https://outlook.live.com/mail/0/?bO=1&sessionId=ec7c7ede-b5d1-490a-be29-837f0b75644a:344:1616 l@https://outlook.live.com/mail/0/?bO=1&sessionId=ec7c7ede-b5d1-490a-be29-837f0b75644a:344:1361 39/_</t.prototype.onLoadFailed@https://outlook.live.com/mail/0/?bO=1&sessionId=ec7c7ede-b5d1-490a-be29-837f0b75644a:351:57059 39/_</t.prototype.import/this.promise</</</<@https://outlook.live.com/mail/0/?bO=1&sessionId=ec7c7ede-b5d1-490a-be29-837f0b75644a:351:56081 u/</<@https://outlook.live.com/mail/0/?bO=1&sessionId=ec7c7ede-b5d1-490a-be29-837f0b75644a:344:2574 u/<@https://outlook.live.com/mail/0/?bO=1&sessionId=ec7c7ede-b5d1-490a-be29-837f0b75644a:344:2679 u@https://outlook.live.com/mail/0/?bO= ts: 2020-08-23 10:53:08Z </p>

I am using "browser.link.open_newwindow.restriction" to force links that normally open in new windows, to instead open in new tabs. It all works fine, except when I click those links, Firefox switches to the new tabs immediately when I click them. I would like the tabs to open in new tabs but I do not want Firefox to immediately switch to them.

Please note that I have unchecked "When you open a link in a new tab, switch to it immediately". Meaning, Firefox correctly does not switch to new tabs for normal links. However, it is switching to the new tabs for links that would normally open in new windows.

I was playing a browser based game and it popped up with the error saying:

an error occured running the unity content on this page. See your Javascript console for more info. The error was: InvalidStateError. A mutation operation was attempted on a database that did not allow mutations.

uh... what? I have no idea what Unity is or does. I have no idea (even looking here), how to open Javascript console, and I simply loaded the page. How did a mutation operation, whatever that is, occur?

Anyone have any idea what that means or how to fix it? If so, I'd appreciate any help.

Today I've refreshed my Firefox and I'm aware that I'll loose all my add-ons/extensions/customization's, but the problem is I've lost all my passwords in my Firefox lockwise! Please help me. I need all my saved passwords ASAP.

Background -- I have a Synology Disk Station. When setting it up, in order to make a secure connection I registered the Domain I planned to use with Synology and received a registered Domain Name. I then applied for and received a certificate from “Lets Encrypt. It worked fine for a few years. I was able to login to the Disk Station Locally using the Local Network IP I had assigned to it, and also able log in via the registered Domain through Synology with a Secure Connection using either method when logging in. Everything worked perfectly. Over a year ago I had some issues with my network (it has been too long ago for me to remember what it was). I could not resolve it, so when I called Netgear Tech Support they had me reset my router to factory settings. This did fix the issue I was having, but I later noticed resetting had changed my IP address. I thought this was not a problem at the time. It was then I also noticed I was no longer getting a Secure Connection on through my Disk Station. Have been trying to resolve this on my own, but I am not having any luck. But I am learning as I go. Present Day – I am still having issues logging in. The message I get when I log into the Synology registered Domain with Firefox is "Unable to Connect". I tried Chrome and get a similar message. When I log in locally using the assigned IP address I get "Warning: Potential Security Risk Ahead".

I click on the "Advanced" button where Firefox displays the Error Message:  SSL_ERROR_BAD_CERT_DOMAIN.  I continue with the exception and able to log into the Disk Station. 

My Goal is to get it working with a secure connection as it did before the Router Reset. -- I have checked all the appropriate ports are open. 5000 and 5001. -- Have checked for any firewall restrictions. -- I have tried replacing the previous certificate with a new one. -- Synology Tech Support does not seem to know, so I figure the problem lies within Windows 10 or Firefox. -- The Certificate in my Windows mmc Console says the Certificate is OK. Weather that is the one that is used for this connection I am speaking of, I do not know. -- The Certificate is current and has not expired. My apologies for this description being lengthy, I just want to make sure I state everything I can think of in order to get this fixed. I do not know a lot about this topic, but am learning as I go. Any help is very much appreciated.

over the last few days there is a small vertical cursor line that appears at the last mouse click location like it's waiting for me to type something there. like the browse button below. if i click outside the box a blinking vertical cursor line appears outside the box where i clicked. it is obviously not a place where input should be expected. this has only started over the last week or so and only with firefox it doesn't happen with chrome. I just opened a story on fox. the title of the story is not a link or a place for me to type or enter text but if i click anywhere in the title text a blinking cursor line appears.

I just upgraded to Firefox 79.0, and now the scrollbars on outlook.com are narrow with no scroll buttons. I fixed this problem long ago by setting layout.css.scrollbar-width.enabled to false. It's still set, but now the scrollbars are back to being narrow.

There is a fullscreen mode that prints a window over the full size of the screen without showing toolbars/navigation/extensions... Is there a "full window" mode that do the same, but over the full size of a window? It would be a simple webview in a system window but without the control toolbars. It would be very useful when tiling several Firefox windows without wasting space for toolbars/tabs... This mode should be specific for a window since I do not want to loose the controls on the main screen-wide window.

The profile folder on the new installation is to be replaced with that from the old. So far so good, I've copied the profile folder from Windows and now want to exchange it for the profile folder on the new Ubuntu computer. Problem is that this is the very latest Ubuntu version (only a few weeks old) and there IS no profiles folder in Firefox!

What there is, is a profiles.ini file but I am reluctant to put it in there because it does not appear to have anything to do with the contents of the ex-windows profile folder.

There is an option to create a new folder but I'm not at all sure what this would do.

Hope you can help

Blessed be Karma

I may have changed a setting ... Normally when I need to sign back in to my yahoo/att email account I can select "stay signed in for 2 weeks" and that works. But as of today, even though I select the 2 week option, when I leave my email page, I have to sign back in upon returning. Every time..... The "stay signed in" option is currently working on Google Chrome and other browsers, but I'd prefer to continue with Firefox. Thank you

I've used Firefox forever, however in the last couple weeks, I can no longer use eBay as the webiste looks weird and my account is inaccessible. (See attachment.)

I've cleared all history/caches/etc. per forum suggestions. No change. So now to use eBay, I have to switch to Safari or Chrome (which I rarely use.)

Using new 2020 Macbook Pro and latest Firefox 80.0 update. Any suggestions would be greatly appreciated!
