I've encountered a very weird behavior: when selecting where to save a file or selecting a file to upload, the browser hangs 100% of the time.

Even when I go to about:memory, click Load, the path selection window appears - regardless of whether I select a file or close the window, the browser hangs and the window stops responding. I tried waiting for several hours - to no avail. Only restarting helps. Same with the upload selection window - regardless of whether I selected a file to upload or closed the selection window, the browser hangs. Before freezing permanently, the mouse cursor stops moving, then lags around a bit before recovering.

I tried cleaning download history, cache, recreated profile, restarted without extensions, in safe mode, disabled antivirus - always the same result.

Please advise me, maybe someone has encountered something like this - I really don't want to start using Chrome. My OS is Windows 11. Thanks in advance.

Every time I play this online game at the site, Wormax.io, it will lag and/or crash the tab after a few minutes of playing. Occasionally, the site will take a very long time to load.

Here's my crash report: bp-4fd287ff-c2e1-4168-8e9d-ac1950211202

• I start Firefox. It works fine for a time
• Then, out of the blue, it says I have no Internet connection
• But, every other browser works just fine
• If I restart Firefox, it again works just fine, until it doesn't, again
• It just started doing this a few days ago
• I know everyone says this, but I didn't change anything other than the automatic update Firefox performed

Does anyone have a solution to this problem? Thanks.

why is FireFox 95 opening multiple windows on startup with Windows 10, Roboform, & Norton 360? FireFox is set to open a new tab, not new windows, so I do not know why it is doing this? I see lots of people asking this question, but there is no guidance online. What is up? This is causing FireFox to use way too much resources, and slows the computer.

Hi sir / madam,

we are encountering an issue that some pictures cannot be shown in the Firefox properly. We tried every methods suggested in your forum but none of them could resolve the issue. The version of the Firefox 95.0 that it is the latest and thus we attached the picture here for tour further investigation.

Would you please help to check and advise for that? Thank you.

Best regards,

Kris

YouTube videos not working with Firefox since recent updates. Videos start to load but don't don't complete. Firefox is the only browser with this issue. Have tried three other browsers without issue.

When downloading files, Firefox no longer remembers the directory path the file was previously saved to on a per-URL basis.

Previous Firefox behavior: #1. download file from website "aaaa.com" to a folder on your computer, "user/frank/companies/aaaa/". #2. download file from website "bbbb.com" to a folder on your computer, "user/frank/companies/bbbb/". #3. Now, go back to the website "aaaa.com" and attempt to download another file. Firefox used to present the previously used directory for this particular URL, in this case, "user/frank/companies/aaaa/" - but instead, now it presents the most recently used directory path, which was "user/frank/companies/bbbb/".

This issue has appeared before and the advice to fix it was to go about:config, search for browser.download.lastDir.savePerSite and make sure it is set at TRUE. I have done this, but the issue remains: Firefox no longer remembers saved file directory paths on a per-URL basis.

Is there any advice on how to fix this problem? - Thxs.

Firefox nightly (trunk) 100.0a1 (2022-03-10) (64-bit) (but previous version too) is crashing the tab if the page contains video content. It happens also in "Troubleshoot Mode". It doesn't happen in 98.0 (64-bit)

System is Kubuntu 21.10 with wayland and PipeWire

Hi,

Firefox is displaying this message: Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to l.mail.people.com because this website requires a secure connection

and does NOT let me continue... HOWEVER, if I copy n paste the URL (https://l.mail.people.com/rts/go2.aspx?h=16465956&tp=i-1NHD-9U-36Hb-1OjSfX9-Hv-5EjIU-1c-Xmrj-1OjOLzQ-l78hyiHVom-1J3ttn&x=6b160f0f640ceeb5fd6f8fe1a3284d4886844914%7c739139%7c20220211%7c021122%7c739139%7c79459191515) to a DIFFERENT browser, there are NO issues with it.

Why is Firefox complaining and how do I tell it to STOP?

I upgraded to 108.01 three days ago. It crashed 3 times in the next two days, accompanied by that popup you get informing you of the crash.

For years I've been using the extraction method of the executable to create a Firefox portable application. Upgrading only involves the install folder. The profile remains untouched, unaltered.

I had an incident of profile corruption a couple months ago, with basically Firefox launching with most features not working, i.e. toolbar buttons, toolbar menus, etc. Yesterday, for a short time, aside from two crashes, I had a similar experience with the buttons, but not quite the same. My default built in Firefox buttons worked, but my extension buttons didn't. I also noticed on a page that I regularly visit, Ublock origin wasn't doing it's regular job of blocking, and the Ublock button was non-responsive.

I'm also in the process of using the Brave Browser for the first time. The reason I'm posting this here about this subject, including a Brave experience, is that at the same time I was experiencing the Firefox erratic behavior, Brave was crashing as well; freezing; tabs not loading.

Considering the Brave tabs not loading, and the temporary Firefox Ublock origin failure, etc., I'm wondering if there might be something in common here? Maybe an internet connectivity issue at the time?

Hello :)

Firefox 102.0.1 crashes after some Time. Firefox then is unable to switch between Tabs and stuck at the opened Website.

For testing Purpose i start over with a new profile and did not install any Add-ons. The behavior was the same, it crashes after some hours.

My System is Ubuntu Mate (Ubuntu with Mate Desktop) in Version 20.04.

Here has someone the same problem: -> https://bbs.archlinux.org/viewtopic.php?id=277649

Thanks for any suggestions.

When I run Firefox on Linux, the window initially starts at 1260x720 size. But when I try to maximize it, then the Firefox window size gets much larger than my screen's resolution. The maximized size is 2800x1600 size, my monitor is 1920x1200 only.

I tried different versions of Firefox and noticed this new behavior started with version 73.0, while it worked fine in 72.0.2 and versions before it. I even tried 73.0b1 and it has the issue already. I see the same exact issue when I tried the latest version 108.0.2 as well. It seems like something got broken in 73.0 unless I'm doing something really wrong.

Not sure if it makes the difference, I'm using MWM window manager on Linux. Please advise.

For the past two weeks, I've noticed that embedded maps make my browser immediately crash. I initially thought it was a Firefox problem, but I have been having a similar issue with Safari. This does NOT happen on my iPhone using the same two browsers. This also does not seem to effect Google Maps or embedded Google Maps, but embedded maps from other services. Anyway, I'm posting here because Firefox conveniently provides crash data, I'm not sure what else the cause could be and I'm hoping someone can help.

Two websites this has been consistently happening with are The Empire State Trail bike path (https://empiretrail.ny.gov/) and a NYC vaccine finder website (https://vaccinefinder.nyc.gov/). Firefox immediately crashes, though with the EST website it seems to be tied to the pathway of the trail being drawn (crashing after I've zoomed in a few times and the path has to regenerate). Safari doesn't totally crash, but forces a site reload and after it fails a second time says it can't display the site.

Any ideas what the issue could be? I'm on the latest version of Catalina (10.15.7), Firefox and Safari and seem to have all security updates for all.

I love how the new tab page clearly states "Never fear losing a closed tab again.", and then when a window disappears it is followed by zero history to recover it. I have not restarted Firefox, let alone my computer since the last time the window was seen (about half an hour ago). It's not in my Alt+Tab tray hiding. I don't even remember closing the tab--though it's possible my keyboard double pressed when I was closing another window. (It's old and has a tendency to double hit keys). But now I have lost a window with at least 20 tabs open--mostly things i had yet to deal with and don't remember the URL to get back to it.

What use is my history and ability to reopen accidentally closed windows if everything just disappears from it within half an hour after the window could've been closed?

I would prefer to keep most of my browsing on Firefox, but I can't constitute that if I'm going to lose months worth of saved tabs randomly.

For some reason, randomly, and now this is occurring more and more frequently, Firefox will just hang and say that "Firefox is not responding," and I have to wait ~30 seconds for it to unfreeze and continue using Firefox. I have tried every potential solution that I could find on the Internet, such as disabling hardware acceleration, creating a new places database, etc., and I still keep getting these 30 second freezes on a pretty frequent basis. Do you guys know what might be going on?

Ever since Firefox updated to the new version I've been having constant crashes. I've tried restarting in Safe Mood which doesn't help. Pretty much Firefox will open, say it's not responding, and then by the time it looks like it's about to restore my tabs it crashes. I had to do a refresh and transferred the backup files from an older session which worked, but then it eventually crashed again. I uninstalled and reinstalled Firefox and tried opening my older profile but it keeps happening. I really need to restore my previous session. There's nothing with my computer that seems to be causing it. I did have 2 windows open with about 8,000 tabs total which I'm sure could be part of the reason, but it never really had trouble before and only just started crashing since the update. Is there any way to fix this without starting over? I read that this is a bug that others have dealt with previously.

Some additional information. I'm on a 64-bit Windows 10 PC.

Ok, this might be REAAAAALLY weird that i'm talking about a firefox version that was released in 2012. But i really need it on this windows 2000 VM. The problem is firefox 9 - 12 is not loading any websites or webpages. It crashes instantly upon opening them. Versions lower then firefox 9 - 12 work flawlessly. Probably nobody will answer this but it is really important for my VM.

In Firefox, the mouse becomes partially unresponsive to elements in the browser and on web pages. This happens after 15-30 minutes after starting up the browser. Common symptoms include:

- Unable to drag and drop elements properly, including text after highlighting it. - Sometimes, the mouse continues to hold elements while dragging. Pressing ESC temporarily fixes this. - Dropdown menus on websites do not drop down when hoovering over them - Other items on websites don't display items when hoovering over them

I have tried:

- Different mouses, including my laptop's trackpad - A Firefox fork, namely Waterfox, but it still occurs - Limited testing with other browsers. No problem occurs - Limited testing on desktop. No problem occurs - Entering Troubleshooting Mode on Firefox - Clearing cookies and cache - Reinstall Firefox (including installing from command line instead of the snap store) - Updated Firefox - Refreshed Firefox - About:Processes doesn't show anything using more than 10-15% of CPU at any one time - Limited testing with a new Firefox profile. No problem occurs - Disabled WebGL and Hardware Acceleration.

Temporary fix: Restarting Firefox, but the problem re-occurs shortly after use.

Using Ubuntu.

Any help would be greatly appreciated.

Just recently, I've been having problems with websites run by Cloudflare. Whenever I attempt to access ANY website that is operated by Cloudflare, I'm often presented with a blank page, or a Firefox error message. Sometimes I'm even presented with the DDoS protection error, even though my computer is clean having being scanned by Kaspersky and Malware Bytes.

I reiterate this and say that it's only Cloudflare sites that are causing problems. Very occasionally they will work for up to an hour or so but most of the time it is error messages or blank pages. Interestingly, other web servers such as Amazon, OVH SAS and Akamai all run with no problems so I wonder what is Cloudflare's problem? Is this something to do with my browser or the web hosting services?

Running Linux Mint Mate 19.2 on two computers. Starting about 2 weeks ago, when trying to sign into providencejournal.com (with a paid subscription) using Firefox 97.0.1, just one of the computers displays an error message, see attached. We have used that site for years without issues, and the other computer still signs in correctly. On the problem computer I have just installed the Opera browser, for test purposes, and with Opera the sign-in succeeds. In F/F, I have tried disabling extensions, allowing all trackers and cookies, and reinstalling Javascript, all to no avail. preference is to use F/F, can anyone offer a solution?
