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.

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.

Firefox Android keeps crashing when tapping the address bar [OnePlus 12]

Hello,

I've been having an issue where Firefox Android keeps crashing whenever I tap the address bar. This happens when any tabs are open (even just 1) and even when I try to open a new tab to try and avoid the crashing.

The issue is consistent and repeatable for almost a year now. Thought updates would fix it as this issue was reported before. However, even after multiple updates, clearing the cache, uninstalling and reinstalling, and disabling all extensions the issue persists.

This is also not just limited to the address bar but also happens when I try to change the search engine from the quick switch on the address bar, search my bookmarks, history and settings, and sometimes when even trying to type into a website. While typing this post I backed away, closing the keyboard, when I clicked back into the text box to type the app crashed.

The only way for me to type in an address or search for something is to close all open tabs and then type into the address bar. Even a single open tab causes the app to crash repeatedly.

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

Firefox Choking When Loading Videos; Chronic Tab Crashes

Legacy Win 7 Pro machines were just upgraded (had no choice but to run them) and FF performance was fine with legacy laptops eight years old. The FF version was much older. With much faster machines and Win 10 running 152.x, now 153.0, there are chronic chokes with FF. Tab crashes. Videos NEVER loading, chronic rebooting etc. -- it just doesn't seem to ever end. But it's not my decision. However -- the shitte rolls downhill right into my lap because nobody else has the patience. Please do not suggest paid 'support' again, because I would get laughed at, given the chronic problems to date over a number of years.

Hi my firefox just updated to version 153.0.1 on all 5 family computers some running win 11 and some win 10 and 2 win 11 pro. now we all experience firefox crashing and not loading pages. When we go to settings and select contact support it says the system crashed. Is there a way to roll back to a version that works without crashing without have to revert to goggle chrome or edge? regards Mal
