I began getting the above message immediately after updating to the latest Firefox version. Whether opening a new tab, or refreshing an existing one, nothing but the crash message shows up.

I have read a number of reports of tab crashing, which I have continually. Running 133.0.3 (64-bit) on Win 11 Home 23H2. Very inconsistent crashes, sometime will open new tabs other times it will crash. I have reinstalled no change. I ran refresh, no change and now when I open Firefox I get a message to restore windows. I can't seem to get that message to go away. Any suggestions, especially about the opening message? I have used FF for years and am almost at the point of switching to Chrome. As an aside, also have problems on some websites processing information/orders when using Firefox. No problem when I switch to Chrome. Thanks in advance......

Since the latest update my firefox seems to have trouble loading video and streaming resources. Browsing through youtube shorts it would not let me scroll down by using the mousewheel or have a delay of 3 secons from time to time. changing to the downarrow to view the next short made me hit an invisible wall at about 200 shorts. browsing twitch also leads to signifficant delays of several seconds until any click action is performed. one time it even crashed so i decided to clear the browser cache and restart my pc. is there a new way the temporary data is stored in the new version? i have 32 GB of RAM and lots of free disk space so that shouldn't be the issue. Firefox used to have no issues whatsoever in older versions regarding videos and streams.

I updated to 133.0.3 just now and Firefox will not load any pages in new tabs. The only tabs I have open are the ones that were open when the application restarted with the update. For example, I could not open https://support.mozilla.org/1/firefox/133.0.3/WINNT/en-US/firefox-help to report this bug because it was not already open (I am reporting to you using Brave). This is happening in both new tabs and new windows.

I get what looks like a DoS attack every day at 7:43. It disables my PC for about 10 minutes. I have traced it a Mozilla task using the task scheduler. The scheduler provides the following information:

The Background Update task checks for updates to Firefox when Firefox is not running. This task is installed automatically by Firefox, and is reinstalled when Firefox runs. To disable this task, update the browser settings or the Firefox enterprise policy setting “BackgroundAppUpdate”.

I have gone into settings but can't find the BackgroundAppUpdate setting to see if disabling this task will solve the problem. Any idea where it is?

Subject: Assistance Required for Frequent Firefox Crashes on Ubuntu

Dear Developer Team,

I am facing persistent issues with Firefox crashing on my Ubuntu PC, and the problem has been ongoing for the past 40–50 days. Despite multiple attempts at troubleshooting—including uninstalling and reinstalling Firefox, clearing all caches, and other measures—the issue remains unresolved.

I’ve noticed that Firefox works for a few days after reinstallation, but then problems begin to surface, such as a half-screen display. Eventually, after restarting the PC, the browser starts crashing again.

Could you please investigate this matter urgently and provide a resolution? Additionally, I would appreciate it if you could clarify whether this might be related to a RAM issue or some other underlying cause.

Looking forward to your assistance.

Best regards, zimmi

I like firefox...used it two to three times a week for over ten years...Now when I click on the icon on my menu, I am greeted by the ansurb: "That doesn't look right." When I try to download Firefox, it will not down load...why are you idiots doing this to your own product?
