Firefox Support Forum

Today for the first time after the latest update 127.0 (64-bit), my many firefox pages and tabs crashed and closed and a pop up to send crash report.

So I have fired up firefox again to find only a single page opens up, I have lost probably 16+ pages with multiple tabs on each, been like that for months, I have 32GB memory so there is normally no issues or slowness. However after the crash, even though only a single firefox page is open, windows task manager shows Firefox (20) and if I expand the task, I can see each firefox is taking lots of memory.

So it looks like the old session pages/tabs are still there somewhere but not accessible, I would like to get them back if possible. I went through reseting it to default, disabling the add ons etc but nothing has worked.

I have the strangest problem. If Firefox is closed and I do a speedtest in another browser, download a file, or do other internet activity I'm getting about 200-250Mbps d/l and 100Mbps upload. As soon as I open Firefox, whether I load a page or not, the upload speed stays the same, however the download speed drops to about 25-50 Mbps. This only happens on one PC, the upload isn't affected, and resolves itself as soon as Firefox is closed. Here's what I have done without any change in this behaviour;

• Rebooted
• ipconfig /release /renew /flushdns
• Removed and reinstalled the network adapter
• Enabled, disabled windows auto tuning and tested (slower disabled)
• Updated Windows
• Refreshed Firefox
• Uninstalled Firefox, deleted remaining folders from Appdata (Local, Low, Roaming) as well as the program file directories and "Mozilla" registry entries. Restarted and reinstalled. Issue immediately resumed when Firefox was open.

Also when connected to a VPN Firefox download speed increases to about 60Mbps and is consistent across other software. If I split tunnel another browser outside the VPN, it is still stuck at 60Mbps. If I close Firefox the speed increases.

This makes absolutely no sense to me, so I'm hoping someone can shed some light on this - but it does seem to be something Firefox is doing.

Thanks for any help anyone can provide.

For a while now, I've been having recurring issues with Firefox desktop freezing and becoming totally unresponsive. If there's any pattern to what causes it, I haven't been able to notice it; sometimes it happens as soon as I open the browser, sometimes it happens after several hours, sometimes it happens twice in ten minutes, sometimes it happens twice in a few hours (however, I can count the number of days it's happened less than twice in one day in the past few weeks on the fingers of one hand). When the browser freezes, it becomes totally unresponsive - it doesn't fade or display "Not Responding", and Task Manager shows nothing abnormal, but it doesn't accept any input at all, any video or other animated material that may have been displaying freezes, and it can only be "fixed" by force quitting from the task manager and reopening. This is exclusively a firefox issue; other programs open at the same time as the browser freezes are not affected.

The only real lead I have as to what could be going on is that sometimes, things don't freeze all at once, but in a cascading effect. For example, tabs, bookmarks, etc. might not highlight when moused over, but still accept the clicks, or selecting another tab might causes the address bar to display the URL of the selected tab, but the screen displayed in the window will not change. Once these cascading changes start, they generally progress to total freeze before I have a chance to do much with that information (only a few seconds), but it's unusual enough behavior to be worth noticing.

Things I've already tried that haven't fixed the issue:

• Reducing the number of tabs used and otherwise reducing Firefox's system resource usage has not impacted the problem in any way.
• Running in Troubleshoot Mode has not had a consistent effect on the problem (the most recent time I did, the browser ran stably for longer than I could stand to use the internet without my ad blocker, but this is only one data point in an already inconsistent spread; prior instances of the problem have occurred in Troubleshoot Mode)
• Disabling hardware acceleration has not fixed the issue.
• The issue has persisted through multiple refreshes and at least one full uninstall and clean reinstall.
• The issue persisted after creating and switching to a new profile multiple times.
• The issue persisted after renaming places.sqlite
• The issue persisted after clearing cache and cookies multiple times.
• The issue persisted after clearing downloads and history.
• And very likely some other stuff that I'm forgetting, I've been trying to fix this on my own for a while now.

I have a Lenovo Win 11 notebook that now requires me to sign in each time I open Outlook or YouTube when I use the Firefox Browser. Edge and Chrome do not require a sign each time I use Outlook and/or YouTube. A setting in Firefox certainly seems to be the cause. I reinstalled Firefox, still same broblem.

A week or two ago I had no issues with Outlook and YouTube. It happens now every time I Open Outlook and YouTube.

I now use EDGE and have stopped using Firefox which has been my preferred browser for years.

Good Morning. I have been using Firefox for 20+ years. Last night it did an update overnight, and this morning I am getting "The Page Isn't Redirecting Properly" error message on my business CRM site. This appears to be the only site having an issue. I have never had this error previously.

I tried all suggestions already including clearing cache/cookies, checking settings, delete history, troubleshoot mode and nothing. The site opens fine on Chrome and MS Edge.

Any additional help is appreciated, this is very frustrating.

Thank you.

My display is too big now and I lose parts of webpages in the "edges"? Search bar when I first sign on shows 120%. How do I get back to 100%? Please no technical jargon. If I can't fix this,will have to quit using Firefox.

Hello,

FIRST PROBLEM (I have been unable to submit a help request from https://support.mozilla.org/en-US/questions/new/mozilla-account/form)

Windows 10, fully updated with the latest firefox version. Email program is MS Outlook through my employer. Email notifications are overwhelmingly loud if the global volume is sufficient for viewing content. Playing with the volume mixer doesn't help. I have searched for solutions online, and every suggested fix entails features or options that are not available on my system. Please provide complete instructions for Windows 10. Please respond to lanzcc@potsdam.edu

SECOND PROBLEM

Submit button on page https://support.mozilla.org/en-US/questions/new/mozilla-account/form never succeeds.

This has been going on for a length of times, the Privacy app or window keeping changing when I used it. This morning, it started back when trying to close it to go to another website. Also, the middle part of the privacy screen keeping changing.

Firefox is not secure because there is something going on every day with the settings. They keep changing on me.

Hi, how can I zoom in and out on websites without changing any display or layout? For example, on some sites, zooming changes the layout of the text so that it all fits on the screen. Or zooming on some sites doesn't affect the size of the images, only the text. How can I zoom in so as to see the page in its original layout but with a wider view, thus preserving the scales of all the elements (as if I were zooming in on a picture) ? (in the screen below, zooming change the relative scale of the elements) Thank you for your help.

I've been using Rightmove Professional on Firefox for ten years plus but now suddenly it's not working correctly as the viewing windows no longer slide. Rightmove say it's due to an update by Firefox and advise to switch to Chrome but I really don't want to - will this issue be fixed? Thanks

Nightly updated this morning and the help menu from the sandwich has stopped working. The menu options display, but none of them function. Mouse click makes the menu disappear as if it's going to show the panel attached to the option.

Version: 129.0a1 Build: 20240613093628

I get the following two error messages when I click on Foxfire. Couldn't load XPCOM; and Entry Point not found; followed by this:  ?Nan@Decimal@blink@@SA?AV12@XZ could not be located in the dynamic link library...

I tried to uninstall the program, but got the same two messages and it would not let me. I downloaded a new version and I'm getting the same messages. Everytime I start my computer, I get the same two messages and have to click out of them to keep going. I've installed another browser, but at this point, I just want to uninstall Foxfire so it stops popping up with error messages all the time.

Anybody know how to resolve this? Thanks.

As you can see in the attached image the highlight is coming out grey instead of blue, which is what is showing when I select 'save screenshot'. It used to be this error happened maybe one in 20 times and it was annoying because I am making these screenshots for use in youtube videos and it becomes unreadable, but now it is every single screenshot even after doing it dozens of times and with different pages.

Multiple users are reporting in Microfix's Mozilla Firefox and ESR Updates 2024 in the AskWoody forum that the two options at Settings | Browsing | Recommend extensions as you browse and Recommend features as you browse were both automatically re-enabled when Firefox updated to v127.0.0. I was able to confirm both those settings were previously disabled in my Firefox browser and re-enabled without my permission in v127.0.0.

So far this as been confirmed in desktop builds of Firefox v127.0.0 and Firefox ESR v115.0.2 released on 11-Jun-2024, but not in Portable builds of Firefox. I'm hoping that the automatic re-enabling of these settings is a bug, and not a deliberate change to make Firefox more intrusive.

I should add that the first time I re-launched Firefox after upgrading to v127.0.0 on 11-Jun-2024 I saw a banner message asking me if I'd like to Open Firefox every time you start your computer?. I'm hoping that clicking the "Not Now" button button once will be enough to prevent this nag from reappearing.

Dell Inspiron 15 5584 * 64-bit Win 10 Pro v22H2 build 19045.4412 * Firefox v127.0.0 * Microsoft Defender v4.18.24050.7-1.1.24050.5 * Malwarebytes Premium v5.1.5.116-1.0.1252 * Macrium Reflect Free v8.0.7783

Got up this morning and FF said all my tabs were crashed - GAH! Could not open ANY new tabs, not even a blank tab, without getting this message. Clicking on restore tabs did nothing. Closing & opening FF did nothing. Cleared startup cache & uninstalled ublock origin (the only extension I had) but that did nothing. Refresh firefox did nothing (except lose some of my preferences). Went to about:crashes and all it says is "No crash reports have been submitted." Every other suggestion I found online was beyond my comprehension. FF DOES work in troubleshooting mode only, but I lose some important functions in that mode. I've been using FF almost since it was born and have NEVER encountered a problem like this before. I hope someone can help!

SLES 15.5 QU2 in Mozilla Firefox 115.8.0esr was not supporting window.close() and it's showing like "firefox already running , but is not reponding to use firefox you must frist close the exiting firefox process , restart your device , or use a different profile"

Hello,

After updating Firefox to version 127.0, I started having problems with the playback of some media files. In particular, audio files with the .wav extension do not show the playback time and the file cannot be played. I can play the same media files in previous versions of Firefox and other browsers (e.g. Chrome) without any problems.

Since I think the problem is caused by a browser update, I would like to ask for your help. If you have any solutions or feedback on this issue, please share it.

Thank you.

I've not been able to download anything on Firefox for about 3-4 weeks now. Every time I try to it immediately fails with no explanation given. The only type of download that works is "Save Image As..." Even trying to download a picture with a download button instead of right clicking nets an immediate fail. I feel like I've done everything to try and troubleshoot it myself, but nothing seems to be working.

I've restarted my computer, ran Firefox in troubleshoot mode, refreshed and reinstalled it, checked for viruses and malware, tried both nightly and ESR versions, tried running them as admin, logged out of my Firefox profile, cleared my cookies and cache, changed and reset the download folder, ran a repair for Visual C++, and reset my windows security settings. I'm honestly surprised nothing has worked.

The only thing that I know I haven't tried yet it refreshing my entire computer, but that's my very far last resort because I'm able to download files just fine on Microsoft Edge. Only the Firefox applications have given me any problems, so if I were to refresh my computer and have the problem still not be solved somehow I'd be deleting everything to get nowhere.

If anyone has any other ideas to try that be very much appreciated.
