Firefox Support Forum

I'm experiencing a problem when I visit certain websites, like 'https://mui.com/x/react-data-grid/'. Every time I try to access this site, the page starts an infinite reloading loop, preventing me from using the website normally.

To make the local startpage as a new tab I tried autoconfig.js and autoconfig.cfg but I got a error message when I open the broswer and nothing change. To remove the url from the local startpage I browse the reddit but I couldn't find answer, I want that when I open the browser it show my custom and local startpage without the url appearing.

Windows 10 Pro v 22H2 Firefox 121.0.1 (64-bit)

I have tried preventing Firefox from autostarting with Windows start up by examining these potential program starting locations:

Firefox-Settings-General: "Open Firefox automatically when your computer starts up": Option not available about:config - toolkit.winRegisterApplicationRestart - set to "false" No listing for Mozilla or Firefox in Windows 10 "Startup Apps" settings page No listing for Mozilla or Firefox in Windows 10 msconfig.exe/System Configuration-Startup No listing for Firefox in Windows 10 Task Scheduler No Firefox program in Windows 10 - %appdata%\Microsoft\Windows\Start Menu\Programs\Startup folder All Firefox extensions (2) are disabled

Where else should I be looking? Thank you

When I select a link in an email, it opens op Edge, rather than Firefox. This just started happening today. I have followed multiple options for making Firefox my default Browser, but nothing seems to work. I am using Windows 11 Home Addition. Thank You!

Hello, Every time I try to open a new tab, either for searching or for opening up any of my accounts such as facebook, a security alert pops up and the URL is resultvIt.com. Please help.

I am unable to login to the DVLC. I get as far as the enter reg number of a car to check it,s been taxed. Then after I input the reg number the next page tell me it is an insecure page. This also happens on my laptop. On both desktop and laptop I am using firefox with duck duck go as an add on. However. In using my mobile with the stand alone duck duck go browser, I can log in and complete the task. This points to a problem with Firefox. Any advice's. This seems to be recent as I have used the laptop and desktop to use the check for a taxed car system ok in the past.

I have two end users that are having a different issues but they are of similar nature. First user can not upload anything to Microsoft Share point. She gets a message that says she does not have proper permissions to upload. She does not have the same issue on Chrome or Edge. The second user is trying to download and or save a file from a couple of different websites but regardless on where she tries to save it on her computer it says she does not have proper permissions to save to "x" file location. She also does not have this issue when she is on Chrome or Edge.

For both users I have tried clearing cache and cookies, Rebooting their computers, uninstalling and reinstalling Firefox, deleting registry keys/user data from the computer itself. I have had no luck with resolving this issue and I can not find anything online that remotely resembles this issue.

Thank you and please advise

To log into my mortgage lender's site I have to enter my email address. Beside this field is the Facebook container symbol; mousing over it warns me that if I enter my email here, Facebook can track me. Mortgage Lender used to allow me to log in with a user name, but now requires my email address, which apparently gives Facebook access to track me. Tried speaking to the lender about this, but they simply assert there are no Facebook trackers on their site. So, any workaround for this besides just doing all my business with them by phone from now on?

I have attached images of what slowly occurs when I don't clear my cookies, websites start to slowly and slowly load less and less until they eventually completely break and wont load and I have to clear my cookies, resign into everything. and rinse and repeat every few days or a week, I also attached an image of what the purchase screen is supposed to look like. Looking at this via Microsoft edge

Hi,

I've been using the following in userChrome.css for many years

1. menu_close { display: -moz-box !important; }

to restore "Close Tab" in the File menu, based on cor-el's response regarding restoring menu_bookmarkAllTabs here:

https://support.mozilla.org/en-US/questions/799856

This stopped working some time ago and I am finally getting around to asking why.

I do have toolkit.legacyUserProfileCustomizations.stylesheets set to true, and other items in userChrome.css are working.

I am using 121.0 at home and 115.0 ESR at work and see the same (i.e. no "Close Tab"), in both cases on Debian testing. I do see this menu item when using the keyboard to open the File menu.

Any idea why this no longer works?

thank you, Greg

I am trying to find answers in relation to my Favourites shorcuts not showing the Icon for some well known websites e.g BBC World News, CNN. Once answer found on the Firefox Forum is: Make sure that you allow pages to choose their own fonts.

Tools > Options > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above"

This is just typical of many answers I find on the Firefox forums whereby the suggested solutions seem to bear no resemblance to my Firefox system. Am I using something different? Everything points to me having the latest up to date version of Firefox. For example if I click on the four horizontal line hamburger on top right of the screen I do not see anything that begins with "Tools" in the menu options. I see "Settings" and "More Tools" but none lead to "Options>Content: Fonts & Colors> Advanced: [X]. simarly, If I click on "Tools" in the menu at the top of the Browser nothing leads to "Options". Any suggestions please?

So Mozilla supports privacy rights- and I've supported Mozilla for that reason- but they want Whatsapp to be censored for "misinformation" ? How does that go together? Whatsapp was supposed to be encrypted and not even Whatsapp was supposed to know the content of messages. How would they know about misinformation? And how do they get to decide what's misinformation now?

how to permanently keep the warning about closing multiple tabs?

Every so often, probably due to an unseen update, when I press the red X at the top of of a page where multiple tabs are open, to see how many tabs are open, they disappear, and the preference option to not close multiple tabs without warning (which says the # of tabs open), has to be turned back on.
