Firefox Support Forum

3 tabs open, left firefox idle on pc and walked away for an hour. Came back, system barely responsive, managed to grab a screenshot. This happens every single day. If I leave firefox idle, or in background for any amount of time, it eats up all the ram and the system grinds to a halt and crashes. Can't get logs, or use profiler. This happens every single day, multiple times per day and only when firefox is in background or pc is idle. I don't use more than 3-4 tabs, this happens on random websites, sometimes even when no websites are open. I can literally open firefox with no tabs and let it sit idle and same thing happens.

Hello Mozilla Support,

Since 2 upgrades ago, anytime I try to watch a livestream, my browser slows right down and then crashes.

I don't care why its happening, I just want a definitive fix for the issue.

I'm so aggrieved at this happening constantly, if you cannot provide a firm resolution to this issue, i will simply move to another browser.

I've tried your about:config setting restart to false and other fixes but still keeps happening.

I await your reply.

With Regards,

Mark

Firefox is blocking/preventing me from visiting a website even though it is secure but Firefox does not recognize the certificate issuer. How do I get around this? Thank you.

As long as I have an incognito window open, Firefox will reopen old tabs everytime I open a new "regular" window, even if "Open previous windows and tabs" is unchecked.

So I enabled push notifications for Google Calendar. Every time there's a notification, Google Calendar ask if I want to enable "Switch to this tab" for their notifications. I accidentally turned it on, then I managed to turn it off. Except it now keep asking me if I want to enable it.

Looking at the settings, the only two options available are "Always ask" and "Yes", with no way of just saying no... why?

This happens now a lot, sometimes I can uninstall Firefox reinstall and it works. That worked this time but only for a few days. I am back once again to where I get this error on every place I visit. I have cleared my cache etc.. uninstalled reinstalled did a restore. It is only Firefox all other browsers work fine. No idea what to do anymore and am sad because I prefer Firefox. I only have standard windows 11 home security stuff installed so nothing special or fancy firewalls. Tried turning on default fire wall. Tried all the instructions on the more info page the error screen leads to.

This error occurs on most all websites or places I need to log into

Secure Connection Failed

An error occurred during a connection to mail.google.com. PR_END_OF_FILE_ERROR

Anyone know why this is happening and a solution?

My laptop is often "borrowed"; access to my "recently bookmarked" items can (occasionally) be inappropriate. I am surprised that there is not a 'easy to access' method to toggle it OFF (!?) I found the below describing how to does this. HOWEVER, I do not find the key (showRecentlyBookmarked).

SUGGESTIONS ?

using: Windows 10 Home 22H2 build 19045.3930

Directly Edit a Preference The menu item switches a hidden preference from true to false, and you can do that directly as follows: (A) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful. (B) In the search box above the list, type or paste book and pause while the list is filtered (C) Double-click the browser.bookmarks.showRecentlyBookmarked preference to switch the value from true to false

I use firefox for browse internet, but after some time firefox start randomly crash. After some investigation i noticed in resource monitor that one of firefox processes has commit 100% of my computer memory. After some time that process reach maximum memory that my computer has and firefox crashed. But windows still was open (frozen with no content and windows XP border).

Ever since the last update the browser's font has been garbled (tabs, address bar, settings page, etc). Some websites show this problem too.

I tried downgrading back to 119 and it displays fine. I was force updated back to 121 and it's broken again.

Safari is showing the links seen in blue after each line but FireFox is leaving them out. Some type of bug or coding problem. This began happening 3-4 months ago. It used to work fine on FireFox. Would love to stay using FireFox and avoid the Safari thing. Love the browser!!! Mark Miller

This doesn't happen every time, but certainly more frequently than it should. Is there anything that can be done about this. Is this about competing for resources. Maxing out the CPU?

Just now occurred. Firefox closed shortly after opening Chrome. No crash notification. Then, Chrome froze, with one of those "Close program or wait" messages.

Hello,

I never had a problem with using File >> Email Link to send a Yahoo email until now.

I keep getting a popup window asking me to choose an application, either Firefox or Gmail.

When I select Firefox in the popup window and click the Open Link, it does nothing.

Firefox doesn't work anymore but when I select Gmail in the popup window, it does work and I can send an email. I had never seen this popup window before until now.

I tried the Incognito Firefox browser and the same issue occurs.

I am using a Windows 11 computer.

Is there a way to get the Firefox Email Link for Firefox working again to send emails?

Thanks

When I log into the "https://wipp.edmundsassoc.com/Wipp/?wippid=JWSU" website, it does not display all the info on the website.

I am including images of the above website before and after logging in. I have also included the way it should look with a screen shot of it from Google Chrome. If it cannot be loaded correctly, I will have to switch browsers.

I have tried clear cache, history, etc. but still have problem.

The Debian Firefox packages available are only 115.6. Thought it would be nice to have the latest. Grabbed all the dependencies according to the Mozilla web site.

Installed Firefox 121.0 as root and placed folder into /opt, as instructed. Went through all the settings and imported my bookmarks.

Now there is a 121.0.1 upgrade available but my browser won't automagically install the upgrade. Says click here to download. So I do. I get the entire tar.bz2 bundle, which creates a full directory structure, as if I was starting over.

Can I just move a few files from that into the existing /opt/firefox directory to get the upgrade? If so, which ones?

Or, can I move few files from the existing directory into the new version, and replace the whole lot? If so, which ones?

Thanks in advance.

I have lost the little navigation segment in Google Maps when in Firefox.

Things that I've done with FF recently are to install on my iPhone, which required a lot of logging in, etc, and which doesn't seem to have synced correctly.

Is there something that I need to set/reset?

I had ~500 saved logins on Firefox prior to it updating to version 121.0 - now I have 15.

Firefox Lockwise app on iPhone still shows all my saved passwords.

How do I get these back and why have you deleted them?

I am trying to block myself from checking on my old employer's website, and I need to block myself from being able to go to their web page. How do I block a specific website? I do not want to access this site, and I find myself checking the site. I sound nuts, I know. But this is for my own good.

I used Firefox's saved logins feature for years and had over 100 logins saved on my laptop. I also use Firefox on my IOS phone.

After an update (I don't know which one, updates are frequent), the app on my phone stopped showing my passwords for most of my accounts. For example, in the passwords section of my Firefox IOS app, it would show the names of the over 100 websites I had saved logins for, but would say there was nothing saved as an email/username or password, just empty boxes. There were 8 logins for accounts I had created on my phone, and those ones did display.

I eventually got tired this and tried to sync my account so I would have all of the passwords I saved on my laptop and on my phone, but Firefox, instead of combining the over 100 logins on my laptop with the 8 logins on my phone, removed all of the over 100 logins I had saved on my laptop and replaced them with the 8 logins that were saved on my phone. My phone also still has the 8 logins.

Now I am missing most of my logins, including the email accounts I used and passwords. This is a big issue for me because I've used multiple emails across my accounts. Resetting all of my passwords will be impossible, and I need to access the over 100 saved logins that are no longer on any of my devices.

I followed the instructions in the "Recover user data missing after Firefox update" support page. The only other profile that showed up for me has no logins saved at all, so that's a dead end. I read other pages about "wrong way syncing", but its too late for me to try to tell Firefox my laptop was the master account because the damage is already done.

I need to know if there's a way to recover my profile with all my accounts. Please, share any information that could be helpful. I need it badly.

Edit: grammar mistakes

I was having some hard drive trouble so I formatted my pc. I did not think much of the browser favorites and tabs because they should have been synced.

This time, however, I seem to be unable to retrieve the data from my old computer, there is even a computer in my synced items (I'm hoping from the system before restoring, windows 11 on what used to be windows 10) but am unable to get anything from it, or see the history ect
