Hi, my Firefox on Win10 doesn't work, I've been forced to go back to Chrome. After a crash in Win10, Firefox doesn't work anymore: it opens, be it launched by me or by other programs, but it just sits there, blank, doing nothing. It is impossible to interact with menus and everything. Task Manager shows two open instances of the browser, using RAM, but the browser doesn't do anything. It doesn't "crash" and it doesn't freeze, it just stays like that. If I quit it and try opening it again the PC tells me it's open already, and Task Manager shows a couple instances staying there after quitting it, as if it stayed stuck. I tried resetting it from the Apps settings of Windows, but nothing happened, I tried uninstalling it and then installing it again, but nothing happened. Restarting the PC a couple of times changed nothing. In the end, I had to go back to Chrome and even put it as default browser because all programs were calling up Firefox which stayed unresponsive. Anybody knows what I should do in a case like this?

hey folks,

since today firefox wont load any websites out of troubleshoot mode. not even settings/ about:config. if i open a page in a new tab it just stays blank and nothing is happening.

in troubleshoot mode i turned off hardware acceleration - nothing changed after restart. i updated the runtime file "Visual Studio 2015, 2017, 2019, and 2022", which is suggested in different help-posts, i deactivated all addons, i created a new profile and also tried an imported one from eralier today - so far nothing has worked.

i also reinstalled firefox with version 99/ version 101 two times, after i cleared %APPDATA%-data.

im also just using windows defender as antivir.

please elp, i'm out of ideas.

I followed instruction several time to uninstall and reload fresh and Firefox will not run, except in safe mode. This issue has happened once before and I solved it by reloading it fresh but this time I cannot get it to run.

In Firefox, my instructor and student grade sheet no longer displays the horizontal scroll bar to bring more data extended off to the right of the page into view. I have an image attached where the scroll bar should be present. This begin in May sometime, and I'm not sure how to fix. I have tried re-installing fresh a few times, and removed any custom settings that might have been in place. Any and all help would be VERY appreciated as one of colleagues is super frustrated and I would love to find out an answer for both him and myself.

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

Upgraded to version 101.0 after getting the pop-up prompt and now every site I visit is taking at least twice as long to load and display compared to yesterday. (Even this support site!)

It has to be something in this release and not my connection, because:

• My mail client is completely unaffected and is behaving normally.
• I tried accessing the sites that were loading/displaying slowest using Opera, and they loaded as fast as they had in Firefox previously.
• Nothing else that uses my internet connection is working any differently than yesterday.

I also cleared the Firefox cache. No improvement.

It's not my add-ons because the only one I have installed is uBlock, which is recommended in various help articles here at the support site.

Nothing in the knowledge base has proven helpful.

Is anyone else having this problem? Is there some tweak I need to make in about:config to fix this? Or is this another case of "wait until the next release", yet again???

When I am typing an address or search term in the address bar, something happens to convert fl to "I. For example, as I type netflix.com, it ends up being net"Iix.com. The address still works (I end up on netlfix) but it looks like there is a bug in how the text is rendered in the address bar. I am on Firefox 100.0.2 on openSUSE Tumbleweed

Hey folks, hopefully you can help with this mysterious issue!

I've been running Firefox successfully on my Windows 10 PC for a long while now. Last night, for some reason it simply ceased to work. New windows and tabs would not load any content. I also couldn't access the Settings at all (clicking on Settings in the browser menu produces no results or feedback.)

Yesterday, I had Firefox open all day (I usually have my computer on all day), and it was working fine. Around 8 or 9pm, I first noticed that none of my open tabs were loading any content, and the tabs had the "loading" animation playing. New tabs would also not load any content. I assumed it was an internet issue as I did see my internet connection get disrupted once or twice. I did not see anything (apps, etc) on my PC updating.

This morning I found Firefox was still not loading anything, although my internet connection was fine. I tried opening Chrome, and it ran just fine. Everything else that it is internet or cloud based on my PC is running fine too. So it seems to be an issue just with Firefox.

I have listed my steps to troubleshoot below, but I want to note one weird thing I observed: Even when Firefox is closed, and Task Manager doesn't show any Firefox processes open, my PC seems to think Firefox is running. For ex. while trying to uninstall Firefox or delete certain files, I would get a warning to "close Firefox first" or "can't perform this action while app is running." After seeing these, I would again confirm that Firefox appears closed and Task Manager shows no related tasks.

My PC build: - Windows 10 Home, 64 bit - Version 20H2 at start of issue (updated to 21H2 during troubleshooting) - OS build: 19044.1526

Things I have tried for troubleshooting already: - I have WebRoot on my computer due to my job, and I asked our IT staff if they could see WebRoot blocking anything related to Firefox on their end. They said it was not. - Used "Firefox Refresh" - Uninstalled and reinstalled Firefox - Cleared app cache / app data - Updated Windows from 20H2 to 21H2

I have Firefox 100.0.1 on my Mac desktop, and Firefox 100.0 on my MacBook Pro laptop. I can no longer access my Microsoft OneDrive account via the web on my desktop, but I still can do so on my laptop. I have gone through your posted troubleshooting steps for Firefox on my desktop, to no avail. How do I get my desktop back to version 100.0 so it will work again? I can access my OneDrive account via the web on my desktop when I use the Safari browser, so the issue is definitely with Firefox version 100.0.1, and not with my desktop.

Just paid $150.00 for a remote session from my computer store. Advice is: My older computer (2004)and it's graphic capabilities aren't compatible with newest FF. So I'll stick with older version (9) until I decide to get new computer. Firefox is my preference, but if I update, it's likely to break again. Please tell me how to stop all update notices. It is maddening. Or, if you can do it, please do. I don't want to use the others. It has crashed twice, just FF, in the last few days. A system restore saved me, but I updated and lost it. Can you help this not wealthy person? I thank you for your fine product, and your help.

I cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.

I cannot open OneDrive with Firefox. I tested Safari and Chrome to see if they have the same problem. They both were able to open OneDrive. The only Firefox extensions I have are Adblocker Ultimate and Print Friendly & PDF.

I have an ASUSStore where firefox is managed by them and is at Firefox 95.0.0.r1 The localhost page shows Boxes with the unicode codes in them - Firefox on a PC to the IP address of the box works ok

I also found that some internet pages work (display english text) and some do not - I have logged a ticvket with ASUS but is anyone able to see an obvious difference between the following URLS These URLs were on the on the Firefox startup screen default webpage Note that Show source of all these pages only shows boxes with numbers in them as well so I can't clearly see on the ASUS what the difference is

The following did not work

   https://www.amazon.com?tag=admarketdeskt-22<tracking>...

but I tried https://www.amazon.com?tag=admarketdesk and this was fine - so then I refreshed the full URL with the tracking tokens - and it was working as well

The following do not work That is they display boxes with unicode values

   WikiPedia - https://www.wikipedia.com
   Facebook - displays boxes with unicode value https://www.facebook.com

The following work with proper english text

Hi - I'm currently working abroad as a photographer, and am having great difficulty uploading image files larger than about 25mb. Is there a Firefox limit on files larger than this, or is there a setting I can use to allow larger uploads? Thanks, Alex

After firefox update to 100.0 - i can't use any of my addons, and cant install new one. All my current updates appears in "disabled" status, and there's no "enable" button. I have many addons, so it's the global problem.

Also, i can't install any of updates from addons.mozilla.org, i get message "Installation aborted because the add-on appears to be corrupt". All addon xpi files are downloaded without problem using "save as", also, after clicking "install" on addons website i see download progress.

Please help to resolve this issue!

I am trying to open one of my bookmarks and it sits and spins for a long time then a message comes up that I am running an outdated browser and it needs to be updated to support their site.  ??? But I think I have the latest update.

Hello! After updating to the latest version of Firefox (100.0.2, 64-bit), I notice that Google search stops working every now and then. By stops working, I mean I can't use their website https://www.google.com or search using Firefox's address bar or search bar. Searching with other search engines like Bing is working normally. In order to get Google search working again, I have to close and restart Firefox. However, after some time, it stops working again. How can I fix this problem?

Hi, yesterday I got a new computer and I installed the Firefox on it, but when I started the browser for the first time, it was a mistake (I pushed the button by accident), so I immediately closed it. It was asking something about allowing the use of coolkies, but I didn't answer to that and simply closed the window.

The thing is that since then my firefox don't load properly. The buttons and the autocomplete are normally responding, but all pages (including the settings) are blank and sometimes it won't start at all and I have to close it with taskmanager to make it open next time (but still blank).

Does anyone have the idea what's going on?

Thank you.

I have this problem CONSTANTLY with 100.0. i keep 2 browsers open, (1 Email, 1 ebay) After 5-10 minutes, firefox "Loses" internet connection. and i have to clear the startup cache, to get back online, only for it to happen again... and again, and again, and again! Didnt have this issue with the previous update. PLEASE HELP! and please keep the answers simple, im not well versed in programming language

From time to time I get an Error Overflow message in Firefox. Sometimes I enter the website directly in the address line and other times I click a link in an email and it tries to open in Firefox as it is my default browser. If I copy the address line to Chrome it loads correctly.

This is mildly irritating as it puzzles me each time it happens.

I have attached a screen snip showing the error.
