To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier.

Why am I getting this warning? I am unable to login.

I do not understand what is meant by the address bar in the info about stopping the Passkey notice in Firefox. I tried typing in the line where the description of the webpage is located with no success. This line: (.https://support.mozilla.org/en-US/questions/new/firefox/form).

Issue: When Firefox starts after a system reboot, it starts on the incorrect desktop. This seems to be off by one; that is, I have Firefox assigned to Desktop 3 (using the Dock icon's Options menu). Under normal operation, it starts on Desktop 3, but after a reboot, it seems to start on (more recently) Desktop 2 or (earlier) Desktop 4. Unsure about what causes it to prefer 2 vs. 4.

This seems to happen after I've shut down (quit Firefox normally, shut down without reopening windows on login, power goes off, power on, log in, then click on the Firefox icon in the Dock) or after a system update (which reopens windows on login for me after rebooting and installing the update). It does not seem to happen after a Firefox update or after quitting Firefox normally and then restarting it from the Dock icon right away.

Pretty irritating, as I have major applications assigned to specific desktops, and Firefox is the only one that seems to forget which desktop it should be on.

Details:

Firefox 150.0.3 (aarch64):

Hello brothers and sisters, i am need help! I'm experiencing performance issues when surfing the 9GAG website. The amount of RAM consumed by this page is growing exponentially. It's gotten to the point where this tab can consume up to 5GB of memory, and that's not the limit. This issue hasn't happened before. I can't figure out what's causing it.

What I did to fix the problem: I reinstalled the browser. I reinstalled add-ons. I reset my old profile, saving only bookmarks and passwords. I reinstalled the operating system. None of this helped. However, my friends don't have this problem with this site. Please help.

Using firefox 140.6.0esr on Windows 10 with noScript and uBlock Origin

Infrastructure for my health insurance provider website uses a self-signed certificate. The infra has a different URL from the main page and was initially failing with "CORS failed", which turned out to be the cert issue.

I copied the infra URL from the dev tools network log and opened it directly, and accepted the invalid cert. I can see the new exception in cert_override.txt.

Then, after unblocking the site in uBlock origin, POST and GET requests to the infra URL succeed, but OPTIONS requests are still failing with "CORS failed", and security status "SEC_ERROR_UNKNOWN_ISSUER"

Is there anything else I can do so the OPTIONS request honors the exception in cert_override.txt?

I get REAL tired by the amount of resources Firefox eats up with each open window. For whatever reason, having multiple windows open prevents Facebook from loading. I'll get 1 story and a "shorts" bar but THAT'S IT. Even clicking the story to rate or comment does nothing. If I start to delete windows; it will decrease the memory usage and then it will open.

However, I DO NOT WANT TO CLOSE MY WINDOWS IN ORDER TO OPEN FACEBOOK! Firefox should not be eating up that many resources. The open windows are of text and/or picture archives. There is no sound or video playing in the multiple windows open. My system literally has 128 gigs of ram memory so it seems very odd to me that Firefox is using between 11-13% with nothing running in the 15 windows I have open.

I noticed that some sites are showing up twice in the history when you go to history and look at the sites you've most recently been to. At first I assumed it was happening just with Youtube, but I have noticed it with other sites as well. This started happening a day or so ago. I recently updated to version 150.0.3, and I have no idea why it's happening. At first I thought it might be because I was signed into sync, but this hadn't happened on previous versions of Firefox and I've been signed into Sync for almost a year now and never saw this occur in that time. I even tried signing out of sync to see if that fixed the issue. it did not. I vaguely remember something like this happening on a much older version of the browser, but I dunno if you guys ever had a fix for it or not. I'm including a screenshot of the phenomenon for the sake of visual reference.

I am using Win 11, Microsoft Powertoys > Fancy Zones to manage the screen space on my 5120 x 1440 monitor. I also have System > Display > Multiple Displayers "Remember window locations based on monitor connection" enabled.

Any program I have besides FF will load up exactly where I had it last. FF shifts I am guessing 8 pixels to the right (or left, as this occurs if I close FF on the right side of the monitor.) If you look at the screenshots, the "opened at default" picture shows what FF looks like when I open it. You can see the xulstore.json file shows the screenX position is -8. If I manually type in 0, close out FF and reopen it, it will still shift back to the right a bit even with the .json still saying 0

How do I do one less thing when I turn the pc on and have FF open exactly as far left as possible instead of shifting over to the right?

Hi, Lately I haven't been able to add a bookmark icon on my 4-row new tab page. There's still to empty spots I would like to fill but can't find the usual + button. Thanks for the help

I have about 19 jillion saved addresses in autofill. I know how to delete individual addresses, but I'd like to know if there's a way to select multiple entries or to delete all of them in a single operation.

Change my password word try to open from apple app keeps coming up. Down load was interrupted why. Also before I change my password word this was coming up as me 55npst5p6d Lost all my browser history an book marks can I get them back?

Best topic is covered by all of the options, unfortunately! If I have done anything incorrectly it was done thru lack of tech savvy for which I apologize for. I have to go take care of the horses now, thank you for any help you may have.

I'm unable to download any of my Intel updates. I've turned everything off that I know could be blocking it and authorized Intel as a safe download. I don't know what else I can do please help. Google states that I should be able to go to the shield and the address bar and turn off the enhanced tracking protection however it will not allow. I've gone to the settings page and set it to custom as well as clear all check marks in that setting. Still nothing will not allow me to download my updates for my Intel drivers. Please help
