Firefox Support Forum

In recent weeks a PopUp is appearing on my Outlook.live.com Hotmail screen: "Add Outlook.live.com as an application for mailto links? There is no choice to Decline only to Add it. You can Close the link with the X but it keeps returning each time I log in.

We are cautioned repeatedly not to click on unknown links so I haven't.

Could someone please explain in "layman terms" why I am getting this, what it's for and how to stop it?

Thank you to everyone.

Every few hours, maybe 4 times a day, XULRunner appears and tabs me out of everything. It says "This profile was last used with a newer version of this application. Please create a new profile."

There isn't a 'create new profile' button. I already made a new profile as well, but it did not fix the problem.

I recently changed to the newest ESR, 115.10.0esr, to fix streaming issues.

Basically, I copied this from an old post that I didn't understand the solution when I move my mouse to the top of the screen in fullscreen, the adressbar and tabs come up, I hate that how do I fix it

Every time I open a new tab, another extra tab opens automatically with the following address: https://0.0.0.1/

showing this message: An error occurred during a connection to 0.0.0.1.

I already re-installed Firefox but this bug keems popping up.

BTW: I did not do a d*** thing. It just started yesterday and is extremely annoying!

I had issues login to my Firefox account, so I reset my password, which cleared my data with passwords and bookmarks. I later found where I stored my recovery key and wanted to see if I can recover that data again.

This has been going on for over a week. I have downloaded and applied the installation program multiple times (>3). The problem persists. What is going on, and how do I fix it? Thanks

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

looks like a problem with Firefox as no problem when using a different browser e.g. Opera. Also cannot log onto Nextdoor.co.uk using Facebook to log on. Again works fine on Opera

Any links from rcsearch.ru to aliexpress is broken in firefox, but works in another browsers. For example click any aliexpress link here rcsearch.ru/-c48920.

Concurrent with the most recent automatic windows update (may or may not be the problem), Firefox with duck-duck-go will not go to almost any site. All I get is a spinning icon or a blank page, not even any error messages. This was even true trying to go to this page until I restarted in trouble shooting mode. Until I can get Firefox working again I have been using Chrome with duck-duck-go. Note any search, i.e. 'hotels in Italy' or even 'MSN' do the same: spinning icon or blank page!! Any help would be appreciated. Also I noticed that my bookmarks were missing and there was no bookmarks drop-down on my tools line. I have run malware bytes and it showed clean, same with CCleaner. I have re-installed Firefox; no difference. Please help. and also, any way to find and replace my extensive bookmarks list? I have reduced my privacy to near zero and turned off firewalls and all limits I could find while testing for that. That did not change anything.

Hi,

Occasionally when downloading files on Firefox, they'll freeze completely (often at the very end.) There is no way to pause or cancel the downloads, except to restart Firefox.

When I attempt to restart Firefox, it closes the browser window. However, when I try to reopen it, I get an error message stating that Firefox is running but not responding. The 'Close Firefox' option does nothing, except make the box pop back up a moment later.

I can't kill the Firefox process in Task Manager or Process Explorer, because it says access is denied. I can't kill it using taskkill in command prompt because it says there is no running instance of the task.

The ONLY thing that seems to help is completely restarting the computer, which is getting frustrating to do several times a day.

I can confirm Firefox is up-to-date. Any tips are appreciated, thank you!

I've been having issues with the websites that I commonly go to no longer appear on the autosuggest list. Websites I haven't gone to for ten years appear when I type in a given sequence rather than more common ones. Website that I go to every day no longer appear.

Multiple websites suggest this sequence:

https://support.mozilla.org/en-US/kb/remove-websites-address-bar-suggestions

I follow the "clear all.." and nothing changes. How can I start anew and have FF re-learn my url history?

After the last update my primary password prompt box is outlined in red. It was never outlined in red before the update. I cannot find any information for this issue. Anyone else experiencing this anomaly (at least it appears to be one since no one has reported it). Thanks

As you can see here, despite me setting custom colors and checking every setting i could find, i can't seem to find what will turn this white color to grey or black,

does anyone know how to fix this?

When I enter text in Firefox 125.0.1 for Netgear's firmware download page at https://www.netgear.com/support/download/ to search for "GS108Ev3" Ethernet Switch, I get no response. It works in Firefox Troubleshoot Mode and works with Chrome Browser.

Firefox decided to remove the total amount of homepage shortcuts. For months, it allowed for 4 rows and 8 columns, with blank "Add Shortcut" shortcuts. This allowed me to organize or split my shortcuts better. This morning, it decided to move all shortcuts together. As per the "Before" and "After" screenshots attached.

Usual disclaimers: Firefox 125.0.1 (64-bit) on Windows 10 No Config edits No extensions currently installed manipulate, affect or otherwise influence shortcuts

Please advise.
