I am running Firefox 151.0.4 on a Win 11 (25H2) AMD Ryzen 5, 32 GB ram. Every time I close Firefox, it generates a crash report. That takes several minutes during which I can't start a new Firefox window. The crash report says the report was submitted successfully but when I look in about:crashes the reports shows they need to be submitted.

I ran in troubleshoot mode and disabled all plugins and did not see any extensions listed. I restarted and it still crashes. Firefox seems to run fine. But the crashes when it closes are annoying and disruptive.

here are the first few lines of a recent crash report: Firefox 147.0.1 Crash Report [@ shutdownhang | mozilla::SpinEventLoopUntil | nsThreadPool::ShutdownWithTimeout ]

I've recently switched to Firefox but am finding some of the performance a bit cumbersome. I am continually being asked to hit "Send" ["To display this page, Firefox must send information ..."] when I am logging into my Outlook email or looking at my bank information. I'd rather not be "resending" these pages each time and am wondering if there is a setting.

Recently, I've been having a problem with signing in to things via my Google account – the problem being that I can't.

Whenever I click on the "sign in with Google", it redirects me to the "accounts.google.com" page, prompting me to choose my account, but once I do, I get redirected to "accounts.google.com/gsi/transform", which is just a blank page with nothing in it (see image attached).

I know this is not a problem with Google, as I have no problem signing in anywhere else.

This happened to me once before, but the reason was one of my extensions, which for some reason interfered with the sign in; however, this time this solution does not work. I tried disabling every single one of my extensions, turning all kinds of protections in the settings on and off, deleting all cache for all relevant sites, but to no avail.

I of course also tried looking this problem up on the internet, but whenever I found someone with this problem, the solution that worked for them was always just disabling an extension.

Thank you for any answer.

I am experiencing a noticeable performance drop in Firefox. Web pages are loading significantly slower than usual, and the browser occasionally becomes unresponsive for a few seconds.

This issue started recently without any manual changes to settings or installation of new extensions.

I have not yet performed deep troubleshooting, but I suspect it could be related to one of the following:

High CPU or memory usage by Firefox processes Corrupted browser cache or profile Extension or add-on interference Hardware acceleration or graphics driver issues Background tabs or service worker activity

I usually work in a healthcare billing environment Avenue Medical Billing Services, so I rely on a stable browser for accessing web-based tools and portals. That’s why I want to properly identify the root cause instead of random fixes.

Can someone guide me on the best diagnostic steps to isolate this issue? Also, what internal tools (like about:performance or about:memory), logs, or testing methods should I use?

I installed the English (US) dictionary add-ons from Mozilla Add-ons (English-US Dictionary and US English Dictionary). Firefox confirms they are installed and shows a “Remove” option, but they do not appear in about:addons under Dictionaries or Extensions. Additionally, the dictionary features are not working on webpages—there is no “define” option on text selection, and no dictionary/lookup functionality appears even after double-clicking words or using context menu options. The add-ons only appear as installed on their web pages.

Expected behavior: Installed dictionaries should be visible in about:addons and provide word lookup/definition functionality in the browser. Actual behavior: Add-ons are not listed in about:addons and provide no visible or usable dictionary features on webpages.

I have been using firefox of a Mobile hotspot from T-Mobile for many years. I am used to correcting for the Hotspot location anomalies. In the last several months firefox thinks I am in Tennessee. I have been unable to force firefox to believe that I am in Northern Ohio (several locations)

Can you please advise? Dan

I'm filling out an appcation for a study permit in canada. My university website said that i should download adobe acrobat reader and use it to open the application pdf. I didn't want to pay for adobe, so i opened it with firefox instead. In the document, there are tab selections that it allows so you can select answers accurate to you and fill out the document. But at the top of the document it says I should enable javascript by going to preferences, then edit, and and then reopen the form. How can I enable javascript in firefox? I'm having difficulty finding the preferences and edit sections.

Hi there. Ian here. My home page "www.news.com.au" keeps wanting to lock me out due to apparent addblockers on my PC. I am not aware of any that I have installed and can't find a way to remove them or turn them off. I am also not sure if this is a healthy consideration in any case. Can you Help me please.
