Firefox Support Forum

I am running Firefox 99.0.1. Lately (probably since the last update) when browsing the web, Firefox will lockup and not be responsive to clicks on hyper links. The issue goes away when I close Firefox and re-open, but after clicking on 3 or four links, it locks up again. MS Edge does not have this problem with the same websites. I did notice in Task Manager that Firefox is opening up 10 processes. Can anyone give some suggestions?

Firefox Freeze after today's update when attaching files on Gmail. Crashed multiple times HELP !!!

Attachment window opens on Firefox program files

Then as you search for your file the attachment window , it freezes the entire browser.

Since installing v100 I have had problems where tabs will not load anything. They will work fine for anything from 5 minutes, to an hour, then randomly just seem to hang. The only way to fix it is to close firefox and restart it, which is a PITA if you are trying to research stuff with multiple tabs and so on.

Additionally, some customers I support started getting SSL_Error_Bad_Mac_Alert errors... only on Firefox, and only when accessing google, and even then it might work fine for half a day, then continuously get that error- but open same page with chrome, and its fine. PCs on the same LAN also running firefox also had no issues with google at the same time as one of the effected PCs, but once updated also started getting the error intermittently (but again still not necessarily at the same time as each other). As you can imagine google is used a lot, and so this can be particularly painful. I have tried most of the suggested fixes for that error, and prior to the upgrade there were no issues.

Issue has occurred on both Windows 10 Pro, and Windows 11 Pro

Is there a way I can roll back one or two versions? It is really starting to become disruptive, and if it continues we will have to look at changing the deployed browsers completely.

Any time I visit a google page that has a map anywhere on it the page goes into a continual loop of refreshing until the google security page opens to make sure I am not a robot. When I click the captcha it reloads the page and the loop starts again. So then I entered about:config to turn autorefresh to false but it still does not stop the google page from a continual reload loop. What else can I do?

I did a refresh yesterday and lost my passwords. I have another computer where the passwords are functioning and I have the "old file" but I don't know how to use it. I clicked on the old file, but just came up with another file called EP7i0nok. It doesn't do anything but it just opens up and it doesn't have anything to restore data.

Firefox has my credit card information and it shows up in a window when I go to pay for something, but when I click on the credit card I want to pay with, it won't autofill. In Settings, the box to autofill is checked. This has worked a hundred times before, but stopped working a few months ago. How do I get the autofill to start working again?

In the past few days Firefox has stopped showing html pages on my other partitions. Has Firefox changed the way they are doing things or is this a new bug?

The screenshot below shows a web page I regularly use that I keep snippets and brief programming notes. It and all links on all partitions except the root drive are no-longer accessible.

I have used Firefox for over 10 years and never had this happen.

Any ideas what may have happened?

I run into this at least once a week, on sites that I know are completely legit, including sites that I recently visited successfully. Once it starts happening for a given site, I can't figure out how to get past it and regain access.

I've asked other folks to visit the same sites at the same time, and they can get through. I've tried accessing them on other devices on the same wifi network, and get through just fine. But I can't get to them any more on my main computer.

I've tried clearing cache and deleting cookies and data, and that hasn't helped.

I'm on Windows 10, and (now) Firefox 100.0. I'm in the UK, using Sky internet -- I don't know if that's relevant, but I didn't notice this problem before I moved here (from the US) last year.

As I said, I can still access the sites on another device (an iPad) on the same wifi, so I don't think it's the firewall in my router.

I don't have any antivirus installed -- just using Microsoft Defender. And I'm not using a VPN or anything like that. My browser privacy setting is "Standard"/

The only extensions I have installed are Facebook Container and LastPass.

What can I do to fix this? It's breaking the internet for me.

This is a horrible web browser that crashes constantly and is slow as hell. Even Internet Explorer is faster than this, and I am switching to that browser and am never reinstalling Firefox ever again.

Firefox 100.0 randomly hangs. Doesn't seem related to particular web site or web page. Is happening with increasing frequency (e.g. every 5 minutes or less).

Browser is completely unresponsive to mouse. Even title bar functions are hung. Must use Task Manager to Firefox end tasks. is happening on multiple independent PCs.

Long time Firefox user (10+ years) about to throw in the towel and go with some other browser unless someone can help with this serious issue. Please help..

Thanks

Hi,

I'm trying to access my Apple ID (appleid.apple.com). When I select "Sign In" the page hangs and never displays the fields to enter my user name and password. The message I get is "This action could not be completed because of an error. Try again or check back later."

Under Settings > General > Network Settings I selected No proxy and I disabled DNS over HTTPS. But neither of these actions made a difference.

Eventually, I had to use Microsoft Edge to access my account.

Any ideas?

Thanks!

Firefox is causing loud fan noise and very high CPU usage. It is to the point I am going to have to stop using it.

Here is my info: iMac 27" 3.5 GHz Quad-Core Intel Core i7 16 GB MacOS Catalina 10.15.7

Increased usage happens when there are 3 or more tabs are open or any sort of streaming on one tab. It goes up and down, but reaches up into the 90% area.

There must be a fix for this. No other browsers have this issue.

I've been noticing lately that Firefox takes a while to start loading pages after it requests a restart or recovers from a crash.

I've followed all the advice in the forums including disabling session restore, but the problem persists.

It seems to be doing a lot of disk activity when it restarts either after requesting a restart or if it crashes and I start it again.

Anything I can do to address this issue?

10+ times a day I'll go to search something using the address bar (google search) and it won't search anything. At the same time it won't load any new tabs unless they've been opened recently and it will open them offline. To fix the problem you either need to fully close out of Firefox and reopen it or open a new window in Private Mode and search something (which loads the pages) then exit out of Private Mode and research in normal mode and it will work... It also won't load certain aspects of websites like automation's in Salesforce, but if you open Private Mode it will load those aspects perfectly.
