I want to use Firefox on my foldable phone alongside several other apps. However, Firefox won't stay open in split-screen view; it only runs in full-screen mode and closes all other apps. That’s a real shame. If Firefox can't be adapted to work this way, I'll have to use a different browser.

Hello all, I have FF 152.0.6 in use on Fedora 43 xfce Qubes OS VMs. The only issue I have encountered is when I try to load the web UI for Proxmox Datacenter Manager. As soon as I log in to the web UI Firefox vanishes. I have tried this in troubleshooting mode with the same results. I can open the same web UI in a Debian 13 Qube and it works perfectly. The FF version there is v.140.13.0esr. These are simply the default versions that come with Qubes 4.3 templates. I can also access the web UI in the original Fedora Qube with Chromium browser with no crash. I have also tried a different Fedora qube with the same failure result as the original.

I can use Chromium but would prefer a streamlined experience with just one browser. I thank all of you in advance any thoughts or suggestions. I am a long time Firefox and Mozilla user.

Have a great day. SS

I finally found the solution! With help from my friends at Dell Computers, that is. The crash was due to the C: drive becoming overloaded with data. On advice, I purchased an USB portable hard drive and moved all the data not needed to be on the C:\ drive. It would be nice to have more than "common sense" to decide which files and folders are needed to run the computer nicely. If there is a book or manual that can list this for me, I'd buy it and check regularly. The computer now runs nearly like a new one and I'll be looking for a while before upgrading. Note that USB hard drives are relatively inexpensive, but need to be treated similar to the way most USB drives are (Don't just plug or unplug while the data is flowing). Storing unused files will pay off so that you don't get caught having to clean house at a very busy time. Enjoy...

I've been using Mozilla Firefox browser for the better part of the last two decades, having always found it to be the most functional and useful over all competitors, who generally seem more interested in raising revenue or spewing puerile and slanted politics. I've been accustomed to the occasional "crashes" and always provided input when they occurred, convinced that the interruptions would be brief and with any issues resolved. Today was different.

Lately, my processor was experiencing some "aging" issues: slowdowns, freezing forcing me to re-start, and random re-starts on its own. Over the weekend I conducted a comprehensive series of diagnostic tests of all features of the operating system. To my relief, the system went back to normal and efficient, including the browser -- for about 2 days.

Early today the browser became slow, eventually inactive, and ultimately crashing 7 times. But all these time were different: my input into the "crash warning box" was not permitted and closing the box only resulted with the next crash. All crashes had the same reason posted on their reports: "Crash Reason EXCEPTION_ACCESS_VIOLATION."

When the crashes finally ended, my browser looked totally unlike it did before:

(1) ALL of the shortcuts I entered on the home page and relied upon for years VANISHED. (2) ALL of the browser windows and the open tabs I was working through at the time EVAPORATED. (3) ALL extensions I saved and used routinely GONE.

By the end of the day, one spent trying to resurrect "my" Mozilla browser with minimal damage, something else disconcerting occurred: the processor's operating system randomly shut and re-started. I don't want to point fingers just yet and allege this was connected with my browser failing, but the coincidence is troubling, one I would recommend looking into. My assistance is, of course, automatic.

So, similar to this post but I haven't downgraded, only upgraded.

OS: Windows 11 (26100.8893) Browser: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:153.0) Gecko/20100101 Firefox/153.0

I can load it up in the morning, load all my standard tabs, then not too long into it a tab will 'crash' and require a reload. The reload then says its a dramatic crash and the whole browser needs to restart. Soft or Hard (i.e. "Exit") restarts always then ask to create a new profile on startup. This means I lose so much configuration (settings, etc) that is not in the Account Sync, meaning huge amounts of time have been wasted setting Firefox back up again every day.

When I go to about:profiles I can see all the old and new profiles (recently cleaned up all the old ones).

I do use my FF Account across various versions of Firefox (run a linux OS that still has a 14x version - need to upgrade OS to get more recent, but its a significant upgrade that had previously failed so not high on my 'want to resolve' list) - all the Windows OS's have the latest FF.

Dozens of reboots every day due to video seizures only with Firefox. Tab crashes causes those I am ordered to support to LOSE WORK. After a tab crash and restore the FF interface is frozen -- no type of input from peripherals possible. This is all supposed to be solved by Monday. If I am out of luck with FF -- just tell me. That's very simple. New machines, new OS and it's worse than under the legacy systems we support after moving up from Win 7 Pro.

I am experiencing an issue where the built-in debugging features in Thunderbird for Android are not working as expected. I am trying to troubleshoot an issue, but the debugger is failing to generate or export useful information. Steps to Reproduce:Open Thunderbird for Android and navigate to Settings -> General settings -> Debugging.Toggle on Enable debug logging.Replicate the issue I am trying to troubleshoot.Return to the Debugging menu and tap Export logs.Expected Behavior:The app should successfully export a text file containing the local IMAP/POP3 commands, synchronization records, and error outputs.

contains no useful debugging .The application freezes or crashes as soon as I try to export the logs.Does anyone know if this is a known limitation of the release build, or if there is a specific configuration step I missed to get the debugger working?

URL at time of crash. https://mail.yahoo.com/d/folders/1

Can get very little done in my eMail for www.att.net. Yahoo.com does also crash occasionally.

I've tried reloading my software for ATT.net, Norton.com, Dell.com and others as I went. Reload went okay, Tried several reboots. Still no luck.

Been to various sites for diag info. I have uninstalled antivirus and tried it, no joy. I have done all the following to each folder - compess, repair, deleted old emails, etc. (I actually have rules that are to do this automatically). I have captured config info, uninstalled and installed fresh. Still have the problem. -- and finally restored so I still have email addresses, etc. etc. This problem has started for me with in the past 2 weeks.

1) ALSO note: I am running W11 home. Mozilla keeps calling this W10. I do not know what the difference is between Home and Pro, but I am planning to upgrade to PRO within 2 months (looking for a reasonable deal on the cost of the upgrade). 2) Wife's computer is W11 Pro, she does not have the problem.

- However I think it may be to do with a recent bookmark entry stored in the bookmarks bar?? The website is a national UK hardware store and it seems to open OK. I cannot be sure but I think the problem started after I added this bookmark. It is a real nuisance and I have had to switch to Edge. Please advise how I might fix the problem.

I'm running TB on Windows 11 on a Dell Desktop machine. It's a pretty basic installation with EE Cyber security, which is I think Norton. I've been using TB for a couple of years but recently it has almost stopped working. I notice from Task Manager that TB is massively leaking memory and consuming much CPU time. I don't think I have any add-ons and I only use TB for email. It's now so bad that I'm even unable to go into TB's Settings or Tools or anything else. I've tried creating an exclusion for TB profiles and TB.exe in the Norton. I've tried starting TB in troubleshoot mode but all to no avail. I have it in IMAP, Port 993, SSL/TLS for incoming mail and Port 465, SSL/TLS, Authentication Required for Outgoing mail. I'm currently often unable to even access mail previously downloaded to the local Mail folders, TB is just hanging with the bar in the lower right corner endlessly running along. Most puzzling of all, is that very occasionally is starts working again and then I dare not switch the machine off! It's become an indeterminate system. Please help, I'm nearly eighty and trying to organize my holiday, which is needs email to make bookings. Thanks in anticipation.

I am running Thunderbird on a new Windows 11 laptop. When I download new messages and try and open them my laptop locks up. Anyone else have this problem? Thanks Dave
