Firefox Support Forum

After a mistaken forced restart (inadvertent pressure on the shutdown/start key), one of the 3 windows I had open is invisible. It shows in the 'Windows" menu as one of 3 but when I select it - nothing. It does not show as a recently closed window in History. I have restarted Firefox multiple times, including deleting the xulstore.json file then restarting (a fix from another similar thread).

How can I restore this inaccessible window?

Thanks

I cannot use firefox. About the third or fourth tab or window I open hangs up, and then all of firefox hangs up. The triggering load can be from bookmarks or a new site. Have rebooted, re-opened: same problem. Have updated everything (including snap), same problem. Uninstalled and re-installed Firefox, same problem. Troubleshooting crashes and will not re-start

I have a frequent problem with dead tabs in FF v121 on Win 10. I tend to have many tabs open (like 15 say) and it sometimes happens that a tab becomes completely unresponsive. It could be a new tab that I open or an existing one that I click on. When this happens I can't do anything. Page reload, clicking on links, entering an address by hand ... nothing happens. The tab is simply dead. The tab is essentially dead. After some time (usually 1-2 minutes) the problem resolves itself. However, it is very annoying as it happens almost every day and sometimes even several times a day. So I am looking for a way to solve, otherwise I will have to move to Brave or some other alternative. Any ideas what could be the problem? I also do not want to restart my browser several times a day as that logs me out of all websites I use including Whatsapp (I delete cookies when closing FF).

In the last month Firefox using google search simply refuses to search, this is becoming annoying to the point where I will start using other browsers. Is there a fix for this?

Whenever I open the find bar while deleting the phrases and words, it shows the one word highlighted or its phrase highlighted on the find bar whenever I reopen after deleting the phrases and words. I need help for this ?

Bug 1362767 is still a problem, even with fission enabled which is apparently the default now. This is a huge problem when viewing videos on youtube and other similar video server platforms. The memory usage by Firefox just accumulates and does not release even after several days. Eventually, Firefox needs to be restarted to release the mis-allocated memory back to the OS. (Win10, FF 115.03 64-bit, Intel I5, 32 GB RAM) A restart can cut total system memory as reported by Process Explorer in *half* or more (!!) depending on how many videos I have viewed since last browser restart using Process Explorer 'Kill Process Tree' function followed immediately by FF restart. It is no longer possible to use an older PC with 8 GB of memory with Firefox to view videos. It takes forever to load, then becomes so laggy that it is no longer functional and is even difficult to kill with Process Explorer because the Windows Explorer user interface gets forced to swap out. (This latter should never happen regardless of memory allocation and is the fault of Microsoft.) I am now using another PC with 32GB RAM and Firefox often pushes the physical memory allocation to well above 16 GB after viewing just a few hours of videos, and does not recover even after being idle and minimized overnight. I have 10 extensions installed. Four of these are video related: Enhancer for Youtube, Video Ads Blocker for Youtube, Video DownloadHelper, and Video Speed Controller. I have not found any improvement in memory allocation performance by selectively disabling extensions. Other people have been posting complaints about this problem for at least 6 years. It makes Firefox practically useless for systems of 16 GB or less. You need to fix this. It appears to be *your* problem; Don't try to deny it, please just make it better. I continue to use FF because of the very useful extensions and greater privacy features than what is available for Chrome.

I am running the latest version of Firefox (115.0.3 (64-bit)) with NO ad blockers. Whenever I try to watch videos on Paramount Plus, I get an Error 3005 message. I can watch videos on Paramount Plus on both Chrome and Edge where I DO have ad blockers running. What else can I do?

I now have 115.0.3 and this problem still exists. It was reported right after 115.0.1 was released. When watching FreeVee on a Windows 10 desktop it stops a short while after an ad plays. It looks like it loses the ability to stream the main movie while streaming the ad. After the ad it plays about 20 seconds of the movie, probably what was in the buffer before the ad started, and then it freezes. I get the circle wait icon, like what typically happens when the Wifi goes down. After a while a message appears saying the Internet is not working. See attached image. Then I get the message (see other attached file) saying Video Unavailable. We're experiencing a problem playing this video. For assistance, please go to www.amazon.com/videohelp. Close Player.

I have been using an old version of Firefox (109.0.1). I am not typically using a newer version because of an essential - to me - add-on which hasn't been updated, and which doesn't work in more recent versions.

On macOS Sierra this old version of Firefox crashes. Troubleshooting mode (I was prompted a number of times) and restarting the browser appears to eventually resolve the crash, but finally there is an issue with the memory and the browser doesn't "work."

The reason for the crash given is " MozCrashReason: Failed to load critical module "resource://gre/modules/WebNavigation.jsm" "

After recent latest update 99.0.1 Mozilla is slow to start. It seems to hang. I use Google as my homepage. Am Windows 7, 64 bit. I tried refresh and made Mozilla my home page. No difference. Chrome opens fine. Was really disappointed with refresh. It dropped a number of icons for shortcuts on my desktop - ????? which were a real pain to replace because making shortcuts with Mozilla is not possible without changing the User Account Control setting in Control Panel which I was unaware of but found after searching for 1/2 hour. I have no idea when this changed nor why it did on the Mozilla side because I have been using Windows 7 for 12 years. I am sending this using Chrome as my browser.

Hi,

I have a very special problem. I have a Macbook Pro (2012) with MacOS 12.4. The old MacBook Pro is not supported by Apple.

Since the update a few days ago, Firefox won't play all videos (for example vimeo.com, youtube.com (not always)). Some videos will be played.

I tried it with deleted cache and website data, with no luck. I tried it with disabled hardware acceleration also with no luck. It also won't work with a new und empty profile (without any extensions).

The sides are loading the video but the playback won't start. Sometimes I get a spinning loading wheel. I suspect the advertising before the videos. Or it is a problem with graphic-libraries from macos, that do not work propper with my MacBook Pro.

With other browser (Chrome, Safari etc.) all videos will be played.

I now, it was my decision to switch to an unsupported OS on my old computer, but everything works (except for Firefox) and I get two more years security updates. I don't want to switch to another browser. :-(

Best regards Kay

I have the latest FF. And this is my system configuration:

Processor : Intel(R) Core(TM) i3-4170T CPU @ 3.20GHz 3.20 GHz Installed RAM : 4.00 GB System type : 64-bit operating system, x64-based processor

Lately I've observed that my FF is eating up lot of my system resources (see Image) and is slowing things down. In Task Manager I've observed it's running several Processes. Is that normal? It's actually more than 31, as many Processes not shown in the image exist down in the list . Sometimes it shows 43.

So what's wrong? Any solutions?

Greetings,

My Firefox keeps crashing randomly even though it's a new PC with very capable good hardware. My old laptop used to run 100s of tabs without any issues.

However, on this new PC, the crashes are fucked even though I barely have about 20 tabs open.

Here are some crashing reports:

Kindly help. Thank you.

Until recently my browser accessed all the sites I have used for years and now I cannot access them. As an example the message I receive is "You don't have permission to access "http://booking.jetstar.com/au/en/booking/select-flights" on this server".

Reference #18.62052017.1660274157.1f6107dd Other sites like my banking site I can access freely on Edge but cannot on Firefox. No error message in that case, just says error try again. All this started after I loaded Norton. I have had them look at the system, and they have, but also point out that it is not them as I can access the site from Edge. I have looked at the help page and their are thousands of people with the same query but no fixes! As a long term supporter of Firefox I am disappointed that I now have to use Edge to do most of my business. HELP

So I know this has been talked about, but none of the "Solutions" work. I'm not sure why or whats causing it, but my YouTube never loads fast, or hardly at all. Usually the video only loads/buffers till about 1 min into any given video. Mind you this is only on 720p or 1080p HD. I never go any higher and my internet speed is ~400Mbps down and ~22Mbps up. I've already tried the following:

1. Disable Hardware Acceleration 2. Clear Cache and Cookies 3. Refresh Firefox 4. Check HTML 5 Video Player 5. Made sure Firefox was updated

I do use some extensions like: - Dark Reader - Privacy Badger - uBlock Origin - Bitwarden (Shouldn't affect) - Honey (Isn't turned on for YouTube) - Enhancer for YouTube (New, so it does not affect load)

Any Suggestions?
