Firefox Support Forum

I typically have several tabs open in Firefox to quickly go from one website to the other. It seems like after a while or if I have more than a couple tabs already open, clicking on a link or choosing a bookmarked site to open a new tab does nothing. By nothing I mean the tab will open with the URL displayed, but FF is not actively trying to connect to the requested URL. The stop and refresh buttons are grayed out. My only course of action is to close that tab and try again, which typically just repeats the previous steps. It's not website dependent because once this begins happening, any attempt to open a website in a new tab hangs.

I do not remember if attempts to open new websites in existing tabs are successful as I cannot duplicate the problem right now. The only think I know that's successful it to close FF and restart it. When I close the program and reopen it, I notice quite frequently that I get a message that FF is already open so I tell it to close and reopen. Also, the last time this problem happened was a few minutes ago and I had four tabs open. I noticed that there were TEN separate processes running, all called "firefox.exe". Opening an error-free, single-tab instance of FF resulted in four separate processes running. Right now, I have two tabs open - the one in which I'm writing this question plus another, static page. This is resulting in SEVEN separate processes running!

I have not attempted to refresh FF yet as I currently don't want to hassle with all the customization I've done and most likely forgotten how to do.

I'm running Win7 Pro with 16GB. Thanks for the help!

I was logged into a website which hanged and when I tried to log back on it started giving me the error PR_END_OF_FILE_ERROR .I've tried to troubleshoot with all the help I could get on these pages and others, I'm at my wits end. The website works on my phone browser, so it's clearly this laptop or my internet dongle.

It's also happening across all browsers. I don't have VPN or antivirus software on except Microsoft Essentials. I've tried removing real time protection on that but it didn't work. I tried creating a new profile of Firefox, nothing. I tried going to about:config page and setting security.ssl.enable_ocsp_stapling to false, nothing so set it back to true I've gone to task manager to see whether there is a task don't recognise so I can stop it, nothing. Pleeeease heeeelp meeeeee!

Sometimes my updated Win7 Firefox stalls when loading websites. Of course sometimes its the website's fault. Crosschecking with Process Explorer I noticed something odd. In Firefox the Task Manager didn't show any great memory use but in Process Explorer it showed huge memory use. How can there be such a discrepancy and which one is accurate? I'd trust Process Explorer because the computer slowed down a lot when it showed a lot of memory use and as soon as I had closed a few tabs (not making much of a difference in Firefox's Task Manager but a huge difference in Process Explorer) all was fine. I'm using a i5 CPU with 16gb DDR3 ram. In almost every aspect the system is just fine, rarely showing its age. But I'm diligent in watching for programs running in the background, always checking Services.msc and MSCONFIG for newly installed programs that have elected to run all the time in the background for no sensible reason.

Today I see that FB fails to load my profile photo album. I get a spinning circle, description and comments section to the right is blank (or photo loads but no description). I check my connection activity, it's basically at 10 kbps. I run some speed tests, no problem.

So I go to MS Edge, everything on FB loads in an instant.

So the problem is FF. And that's on top of the 50%-100% of CPU that every click on FB produces. I compared it with Edge, 5%-50% of CPU.

So before I give up on FF and switch to Edge, can someone recommend another version of FF that is relatively lightweight for a low spec laptop? The latest version is a no go, as I understand it needs at least 8-16 GB of memory (!).

Thank you.

I usually open link google in the same tab when i clicked it. but now it always open on new tab, i tried

-browser.link.open_newwindow / 1 -browser.link.open_newwindow.restriction / 0 -browser.link.open_newwindow.override.external / 3

And its work, but when i open external link on whatsapp web, it doing the same like open link on google (open in the same tab), before this error happen, whatsapp web was always open the new tab for external link.

How can i set for google opening link on the same tab, and whatsapp web can open external link on the new tab?

I recently installed version 78.02 of Firefox as a second copy. The first copy is version 67.04. I left the older version as the default until I had the new version customized. I have tried to make version 78.0.2 the default version, but version 67.0.4 remains the default. I have tried both from inside of Firefox in the options menu, and from the program defaults in the Windows 7 control panel. Neither has any effect and version 67.0.4 remains the default. How do I get version 78.0.2 to be the default without uninstalling version 67.0.4?

Hello. My ISP speed 120MB/s I try to upload big video to youtube. If I use Firefox then speed it 25Mb/s. When I use MS Edge then uploading speed 100Mb/s (Checking on router). Why? Where is limit set? how can I speed up upload?

Hello,

I have been a long-time FF user and have been generally well satisfied with it.

I have also been a long-time user of RT.com for news & opinion so I was dismayed when in April 2019 I could no longer access RT from my FF (V 26.0.1). This was a major inconvenience to me although I could still access RT.com via the FF V 81.0.2 which I run separately, I could not store links its links with the Tab Groups option I use on my older FF version.

Note: I use an outdated version of FF in order to use the Tab Groups add-on V 1.0.2 which I've used since making FF my browser since the versions available on FF Quantum are profoundly inferior to it and don't allow access to literally 10's of thousands of my stored .json files from the older program.

Happily, in January this year I found that access to RT.com via my old FF had been restored… until yesterday when it seemed only intermittently available, and today, appears inaccessible.

I am writing to ask why this has occurred and what can be done to restore access to RT.com via my FF V 26.0.1.

Thank you.

SECURE CONNECTION FAILED. Two days ago Firefox upgraded, now I cannot access my credit union online account. Oh, I can if I use Chrome. But I do not want to use Chrome! I called the credit union. The problem is not on their end. I cleared the cache and history on my computer. I rebooted my router. Nada. I need a human being who can explain to me in plain English how to fix this problem. I am computer literate, but I don't have a degree in cyberspeak. I hope the only answer is not that I abandon Firefox and be forced into Google-world. Please Help!

HI. Firefox has been regularly crashing over the last month or two. Today it's crashed 4-5 times in 10 minutes. I tried sfc /scannow just now and there were no integrity violations. I've always submitted the crash report immediately after each event, however the last few were unsubmitted when I checked the log just now, so I've submitted them too. Firefox has always been updated to the latest version. Any ideas? Cheers Ian

...just like it does whenever a file finishes DL'ing. This leads me to believe that FF is downloading "something" every time I start the program. So why/what is it doing?

I am not able to login icloud.com and pass 2 step authentication process. After filling up login and password, message "Failed to verify your identity. Try again." appears. Althrough in mobile phone message with code appears. Firefox 82 unable to change from icloud login page to code input page for authentication.

WHAT HAPPENED: 1. I signed out of Mozilla on the owners laptop and entered my own account information 2. As I signed out of my account, I checked the box "delete data from this device", so that my data would not be saved. 3. The owner entered their account email but Mozilla did not find it so the user created a new account using the same email address as prior.

THE PROBLEM: all data is missing including bookmarks, passwords, etc. It appears Mozilla sees the account as new. Even when the user logs into a site they frequent regularly, the site does not recognize the user and requires login and password and verification of the user. Seemingly like the device is registering as new to the site.

STEPS TAKEN TO RESOLVE - UNSUCCESSFUL 1. I used the restore bookmarks option to restore to a previous copy

    A. according to the user, the restored bookmarks are not current

2. I verified that there is only one profile for the user 3. I verified that the profile has data in the local drive and the profile default is set to read the profile on the local drive

NEED HELP: 1. Restore the account completely so that all sites recognize the device and all bookmarks are restored

Thank you for your time and help to resolve this situation! Dawn

When Firefox is closed, the https://html.duckduckgo.com/html/ tab opens empty with no POST request data. How to fix it?

Проблема с поддержкой сертификатов безопасности возникала и ранее: Firefox не корректно подбирает сертификат для соответсвующих защищенных сайтов в автоматическом режиме. В последнее время использовали ручной выбор сертификата, т.к. зачастую Firefox подставляет первый из импортированных сертификатов. Теперь в версии 81.0.2 и ручной выбор не работает. Был момент, когда Firefox выдал окно с запросом сертификата, но был выбран "не тот", который нужно. При повторных запусках - данное окно более не появлялось (почему?). В настройках безопасности - Сертификаты - установлен режим "Спрашивать каждый раз" но окна с выбором сертификата не появляется. Firefox отправляет первый попавшийся сертификат, сервер его не принимает, возникает ошибка защиты. При этом те же самые сертификаты работают без проблем с теми же страницами в Gogle Chrome и Opera как в автоматическом, так и в ручном режиме, и подставляются корректно.

my microphone on your site is not working! I have completed all settings and permissions! It works at the Opera - it doesn't work for you! мой микрофон на вашем сайте не работает! Все настройки и разрешения я выполнил! В Опере работает - у вас не работает!

One of Opera's best features (for me) is Speed Dial , which is roughly similar to Top Sites ... I use it a lot - how do I import Speed Dial entries into Top Site? Thanks

Now that i have v. 81.0.2 64-Bit, the first time I opened it today i saw one of those yellow bars at the top that said that there was a script on the page. Since my email program SeaMonkey was opened too, that seemed to run busy as well as Firefox. When am I going to be able to open these programs without this business of scripts running. Neither program pays any attention to the option to stop scripts.
