I've been using Firefox for about six months. I'm a MacBook user with the most recent version of Sonoma installed. After a month or so of using Firefox it starts crashing and freezing. Sometimes I can't restart it for several minutes. Whenever this happens, I refresh it. I've refreshed it about twice. I've re-installed it twice too, but it keeps happening. Most settings are default, but I wanted to include the settings in case this could be the problem: - I've turned off Firefox home content - I've turned off all passwords and autofill features - Never Remember History - Do Not Track and Tell Websites not to share/sell my data are turned on - I left the standard-level security settings as is

I have one extension installed.

The only other browser I have installed is Safari and I am not having these issues. I should add that I don't receive any error messages when this happens, it just freezes. The most recent issue is that I was clicking on buttons on a website and it wasn't working, but when I started using the Safari browser (which also set to private mode) it worked fine.

When it works I love Firefox and would like to keep using it. I am wondering if there is anything I can do to fix this.

Dear,

I have been using Firefox Developer Edition for many years without any problem. I sync Firefox on my different PCs, so they are basically all the same in setup. Unfortunately, Firefox now crashes constantly on my main PC. I have therefore temporarily switched to the default FF variant.

Of course I have tried all the steps shown here on the forum but without any result that I can see. Both in safe mode with or without addons. No matter FF crashed.

The error ID: Crash ID: bp-20d91ca4-1f79-4211-a3d5-4fd7c0240507

I hope someone can help me on my way ,

Regards,

Reinder

My firefox now freezes when I click in the URL bar. NO solution I have found so far other than task manager -> end task and restart the browser. Occasionally that will work, other times it will immediately freeze again.

Historically I have had a LOT of tabs open, more recently less than 20 tabs. I have never seen the issue before.

Windows 10 22H2 Ryzen 3600 32GB RAM Nvidia RTX 3060 LHR 3 Monitors 2 - 1920x1200, 1 - 1920x1080

What I have tried so far: - reboot - restart firefox - "refresh" firefox - troubleshooting mode - removed all extensions - removed some extensions - reduced tabs down to a few - tried to click in the start page search instead of url bar - turned off hardware acceleration - turned on hardware acceleration - turned off TLS DNS - using only 1 window at a time instead of 2 or 3 - waited for an hour or so and window did not become responsive

None of these solutions fixed the issue. A screenshot would be useless as the window looks fine, but the UI is unresponsive.

The animated images of the articles are loaded once every 3. On Chrome Android I have no problem.

I solve it manually by resizing the page, so they load.

Where could the problem be? In the animation of their site? Do you have any advice on a fix?

Hello. For some unknown reason, when I open "New Funclub Casino" everything runs just fine: login, search, funding, history, etc... However, when I click on a game to play, it begins to open a new page to load, immediately stops and displays "Device or Browser not supported." I can't pinpoint a reason nor have any explanation as to why this just started happening when everything functioned perfectly fine without any issues in the past. What am I missing or not aware of that's changed?

Thank You, Jeff Billo (Soltarius7)

As of this morning, I'm unable to click on links in emails and have the URL open in my default browser. When I click such a link, the menu bar darkens as the mouse button is down, and lightens when the mouse button is released. Nothing else seems to happen.

I hope you can help; this is a major problem.

Im using Thunderbird Beta release. Starting last week, my PC would become extremely slow, to the point it would nearly come to a complete halt. After digging around, I realized it was due to excessively large Thunderbird NSTMP files that were being created. I would delete them and the speed would improve. But then a while later, the NSTMP files reappear and gobble up all my Harddisk again. Part of the issue is the sheer large size of the file, which will consume all available space on my HD, which at present is 600GB. But it also eats up all my RAM so my system slows down til the NSTMP file is fully built.

I use this as imap with Gmail installed on a PC with a 1TB SSD

Today after my pc started slowing again, I started poking around and noticed my main Inbox is massive, 29GB, which there is no chance its that large. All Mail is only 1GB to give perspective

This has been going on about a week.

I tried repairing my inboxes and other folders, but that does not seem to have helped.

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

Hi, starting with Thunderbird 126.b02 (al least) there are very heavy perfoming issues. Beyond crashes it takes approximatly 10 seconds to open a specific email. Moving to another account is much more difficult: taking itself a much of time it takes supplemental time to open the INBOX. Despite an Raphael on-dice-graphics I'm running a discrete Radeon RX 6700XT. HDD is far away from being over-lastet or running out of memory

Any ideas? Appreciated. Thx. B.

Hi everyone,

I'm running Firefox which I compiled with vaapi support because I was trying to use hardware acceleration for videos, so I think this bug may have something to do with that. Every time I open a pdf file my browser instantly crashes. When I use troubleshoot mode I have no such issue. I then tried with a fresh all-default user profile with no add-ons, nothing, and still I crash when loading a PDF. Any pointers would be appreciated.

All downloads I make inside of Firefox are automatically failing, with "Failed" message. This only happens in Firefox, Microsoft Edge downloads are perfectly fine. I've tried starting in troubleshoot mode, disabling anti-virus, clearing cache and downloads, rebooting PC.

Some recent changes in PC include: changing TEMP and TMP system variables to another drive (I've changed them back to C drive, had no effect) and making C drive a dynamic disk. Yesterday downloads were working fine. Thanks in advance.

Hi, first the last update tried a few times over some days to install. Never got confirmation that it has been installed successfully. When I go to "About Firefox" I'm getting the information that I'm using the latest version.

Now I have problems, mainly when using facebook (especially when I try to play games through facebook) that Firefox uses enormous amounts of CPU and Memory. This does not happen all the time but at least in 70% of tries. I attached 2 screenshots

If this happens I'm not able to close Firefox the normal way but have to kill the process in the task manager.

Any quick help would be appreciated. I would also like to know if I'm the only one experiencing this or if it's a common problem.

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

Hi Friends.... This morning logged into my website as usual and this message appeared on the home page. I have not checked the link as it seems potentially malicious ... It does not appear when visiting my site on Safari. I have emptied the cache I have been through troupbleshooting mode I have reinstalled Firefox and it still is there..

How to rid myself of this

All help gratefully received Graham

Macbook pro 2017 OS 12.7 Firefox 125.03

Device: Surface Pro X SQ2 OS: Windows 11 Home for ARM (Up-to-date at time of writing) Firefox Version: 125.0.3 (AArch64 up-to-date at time of writing)

I am having an issue with Firefox and video playback, specifically on YouTube. When I play a video in default view mode, the playback is super choppy / low frame rate. When I change to theatre view or full screen, playback works perfectly.

I've tried incognito windows and troubleshooting mode with no improvement.

Microsoft Edge works fine.

Not sure where to go from here.

Hello, I have Webmail by Godday. I have been using Thunderbird for many years to connect to my accounts without issue. Past couple days I get an error message saying it can't connect to the server. Godaddy says they haven't changed anything. I can log in on Webmail but not with Thunderbird. Thunderbird brings up my mail from before it couldn't log in so I have all my stuff I have saved but I can't get new mail or send mail. I deleted Cache, restarted and all that... Disabled add-ons in trouble shooting mode. Here is what I got. Much appreciated

Along with most of the world, I hate threads. My normal practice is to keep only the last email in a thread quoting all the contributions, and to delete the rest. Then I have one email with everything about that in it, with a history trail. I've done this for years and years. Then, some time last year, after an update of Thunderbird, everything was in threads. Someone replies to my message, and the thread goes missing from Sent, and appears in Inbox, but not marked as unread - you only see this when you expand the thread. If you reply, it jumps back into Sent. Finding anything is now a time-consuming nightmare. But there also appears to be at least one bug.

Suppose I now go into a thread and delete an intervening email. Thunderbird clears the preview panel of emails. If I click on Sent then back in Inbox, they reappear! But if I'm now confused as to exactly what that delete did to how many emails, I click Edit / Undo Delete. What it seemed to do tonight when I hit the Delete was get rid of a big chunk of the large thread, including some emails I hadn't read yet, and some not in this or other threads! They are not in the Deleted folder - they are gone! I think it has also done this before. What a mess! As for evidence, reproducing it is not something I want to do.

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

I have been using Firefox as my primary browser for a very long time. Now, every time I start Firefox, I get a message that the update failed, and that I should manually download the update file and run it. I do so, the update appears to work, and Firefox behaves, until I stop it and restart again. Then I get the same message. I looked online - it appears that others have had this problem, but no clear solution. I am not willing to use Edge, but am beginning to wonder if it is time to leave Firefox. I would appreciate a solution, preferably a reliable one. Thanks, Joe Purvis Email hidden for privacy reasons
