I have a new macbook air running Sequoia 15.3.2, firefox is up to date, my battery which should technically last about 12 hours and I only get 5. Ran through everything with Apple and they said it is a Firefox issues. I don't have any extensions, add on etc. Thoughts?

Late last week I updated Firefox to the latest version. Ever since, I keep getting the same error message that I typed in the subject line. I've seen previous recommendations on how to correct it, but none of them work, probably because there's been more updates since what I've come across. I'm getting this error message on multiple sites, including my bank account and my business email account. I'm presently typing this on a different browser (Brave), because I was getting the same error trying to find answers using Firefox.

Any assistance would be appreciated; thanks.

Bookmarks have been intermittently disappearing for weeks but I could always see the blue star when I visited favorite sites that I use upon starting my day that I had bookmarked. This morning all bookmarks were missing. I tried clearing cache which had worked to restore some bookmarks that were missing. Now everything is gone and I cannot recover them. There is an error that appears when I open Firefox re: bookmarks and I followed the steps but it did not work. I really need my bookmarks to do all the things I need to do, like everyone else, including medical information websites. I hope you all can get this figured out as it has been a problem for a month for me, on a PC. I know my favorites are stored somewhere on this computer but I cannot make them populate. If someone would like to take control of my computer and fix it for me, I would happy to let you do that. I have run sfc/scannow and chkdsk/f as well as a total virus scan with Norton. I have restarted my computer several times as well as done a complete shutdown several times.

I'm on WinXP and Win7; FF is there respectively on ESR 52.6.0, and 56.0.2.

• • Pls refrain from lecturing me on updating etc. I need it to be this way for umpteen reasons. Thanks for understanding.**

First, all of a sudden all my legacy add-ons were disabled. Most of them ensure FF looks like it did ages ago, which is what I'm used to, and need, to function properly myself. They overall are no longer maintained or downloadable, hence the need to stay on lower browser versions as well.

Managed to fix that.

Then, last Fri, my webmail provider missed updating their security certificate. They seemingly later do, but I am left unable to access their website from FF on both machines, and Chrome on the XP. Disaster.

The error messages I get are, in FF:

[www.netaddress.com] uses an invalid security certificate.

The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported.

Error code: <a id="errorCode" title="SEC\\\\\\\\\\\\\\\_ERROR\\\\\\\\\\\\\\\_UNKNOWN\\\\\\\\\\\\\\\_ISSUER">SEC\_ERROR\_UNKNOWN\_ISSUER</a>

and in Chrome:

classic.netaddress.com normally uses encryption to protect your information. When Google Chrome tried to connect to classic.netaddress.com this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be classic.netaddress.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Google Chrome stopped the connection before any data was exchanged.

You cannot visit [classic.netaddress.com] right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.

When running a SSL server test on their certificate it turned back: Chain issues Incorrect order, Contains anchor

No idea if that's relevant.

I tried just abt everything I was handed, could think of, or googled. Adding an exception included. Nothing works. Logically, the error should be on their end (w/ their old certificate, it all worked fine, now it doesn't), but somehow I keep being directed to that your root certificate having expired is the culprit.

Earlier today, I took the plunge and updated FF to 72.0.2 on the Win7 machine. (My webmail doesn't have full functionality on Chrome, so I was still very hampered in that regard there.) Now I can access the webmail -- but all my add-ons AGAIN are disabled. And what I did before to make the work does now NOT work anymore.

Can someone pls take me out of my misery? My whole existence is falling apart. I am already on 75 % (invisible) disability. Nothing works, least of all I. I am days behind on an already massively overburdened schedule. Not everyone can handle constant updates and their user interface being changed all the time. Some ppl are dependent on things looking and acting the exact same.

I'd like my add-ons back functional on the Win7 machine, and my webmail back -- INCLUDING the add-ons remaining functional, on the WinXP. Thank you.

System: Linux/Fedora41 Firefox: 136.0.4 Monitor: Acer 27" 1920x1080

When I open a FF window, it opens full screen vertically and to some width horizontally, both dimensions not desired. My usual style (for the MANY years I have used FF and Linux) is to use a FF window that is NOT full screen in either dimension since I normally have multiple windows open simultaneously. This FF behavior has started just recently.

This behavior occurs when starting FF from the FF icon on the desktop, when opening a new window from the FF main menu, or when opening a new window via the 'Open Link in New Window". (Perhaps other ways as well: these are those I encountered.)

I have tried: .... Opening FF/resize window to desired size/close FF using 'Quit': no change on restart .... Deleting the xulstore.json in the profile folder/restarting FF: no change on restart

I would like to restore FF to its previous action: open new windows at the same size as the last one referenced. Can someone help?

Thanks.

Try to get "tvlistingszap2it.com" --(which I have been using for 5 years)--- but it opens "newsnation" Started doing this on 17 Mar, 25. What is wrong ?? Can you fix it ??

Hello. This question concerns the Windows 11 desktop version of Firefox.

I have long used the Home and End keys on my extended keyboard to scroll to the very top of any given page in Firefox (Home) or to the very bottom of that page (End).

But, lately, I notice that, for no reason I can figure out, Firefox no longer responds to those shortcuts. Now, when I tap Home or End, the page may, at first, scroll up or down slightly but not to the top or bottom. If I press Home or End again, nothing happens at all.

Sometimes, if I press Ctrl + Home simultaneously or Ctrl + End the page will scroll to the top or bottom respectively.

Why has Firefox's behavior apparently changed? Is there an issue with my keyboard or operating system settings? (I use a Logitech G915 keyboard.)

Please let me know how to restore Firefox's shortcut functionality, where I can tap just Home to scroll to the top of a page or only End to scroll to the bottom of a page.

Thanks and be well.

When searching on webpages, the image will look blank with a red box outline, or will have the image and the box outline. This happens whether or not the image is an interactive element. Even after refreshing the page the problem persists. In private or regular windows it happens. After tapping on the red box, the image will load, and usually stays loaded if I leave the page and then come back.

A screenshot is below of what the boxes/images typically look like Attached screenshots

This is on the android mobile version of FireFox.

Since the last update, Firefox is not working properly. The search engine is completely dead, not working at all, and anything related to Google, like Gmail, never opens. I've tried several things, but nothing works.

My search engine has stopped working. I just get blank pages when I enter any subject in the search bar. I am forced to open a private window which always works without issues. Closely related to this problem I believe, is the fact that any online forms I try to complete and submit will not submit. Again if I copy and paste the address into a private window, I can complete and submit without any issues.

It is getting very frustrating to keep having to go private windows.

When I open a new tab, it opens fine, I get all the articles as per normal. But when I enter my search criteria I get nothing (see attached screenshots)

Two financial websites I normally look at with firefox suddenly have no images anymore. I think it's the last Firefox update that caused it. Both websites look okay with Chrome.

i use the duckduckgo as a searchengine , so i got some issue while searching . the issue is whenever i search any thiing on the websearch the response i got is totally blank you need to look at this so i added the screenshot
