I-Firefox Community Forum

I get the above message when signing into a web site that I use. What does the message "404 INVALID URL" mean, why does it appear and how can I correct it?? I have checked the URL (address I am trying to reach) and it is spelled correctly.

Beim Anmelden zum Online - Banking kommt folgende Meldung(nur bei Firefox):

"The requested URL was rejected" und Your support ID is: 14509441730520179491

Was ist da los? Bei anderen Browsern geht der Login! Danke

First, is there a list of commandline options?

Second, I would like to be able to start Firefox with a specified URL from a batch file -or- a .net program. Then, either close FF -or- switch to a different URL. is this possible?

The Russian language is not listed in the "To" part when I want to translate a page. Although it IS listed if the page is in Russian, so it suggests to translate from Russian to some other language. The language is installed in settings.

How do I get the 'open in new tab' option back when I use the right button on my mouse. It does not appear on the menu when I right click? This is a change overnight and I have not altered any settings.

For some reason, I cannot access any links imbedded in my favorite browser sites. I don't have enough knowledge to put into words what I'm asking but I'd like to be able to click on a newsletter or a article on a websitye. The messages is always "cannot access this site (or link). Any suggestions?

This latest update to 153.0.4, which I did a few days after being notified, it messed up firefox. Finally rebooted, got it up again and now if I right click, I do not get the " open in new tab" option, eg, on youtube videos.

hi everyone, first of all, happy new year.

while browsing reddit, i keep seeing these strange underlined empty links on random words/names. for example this comment here: https://www.reddit.com/r/moviecritic/comments/1hpse0f/comment/m4jxdwq/ shows the name of actress underlined.

i disabled all my extensions and the problem persisted. i checked using chrome and the problem didn't exist.

on inspect element i found something called faceplate-tracker though.

any clue what is this? and how to deal with it?

I prefer Firefox to Microsoft Edge - but when I click Read more to continue reading an article in the same page I am on - it opens a new blank tab. then I have to go back to where I wanted to read more - and it is there. But why is it opening a blank page first? i tried changing settings but there is no "Open link in target" - there is just an option to open a new window or tab - when all I want to do is see the rest of the article. it works fine in MS Edge - but as i said, I prefer FireFox. is there a way to fix this?

Currently when I click a link in and email, it always opens in Microsoft Edge even though my computer has Firefox as default browser. Is there another setting I'm missing?

General Default browser

Firefox is your default browser. Good choice.

My problem is as described in the subject line: I'm getting multiple instances of Firefox opened when I click links from email or web pages.

This just started happening within the last couple of days. In the past, whenever I opened a link a new window was opened in the already open instance of Firefox. Somehow some setting has been changed (a guess) that has caused a change in behavior.

Firefox is my default browser, but I do keep Chrome open for some testing of HTML/CSS I'm writing. Chrome is NOT my default browser.

I did some searching without finding anything I understood well enough to implement.

I would appreciate any help with this issue as having multiple instances of the app running is driving my octogenarian brain nuts.
