1st, the accessibility drop-down field above, in this submission form, is not appropriate. Please add "Other" as a category, or add more troublesome categorizes.

When 'm working to upload an image, for example, into an article I'm publishing, let's say on LinkedIn, as I change directory (folder) from the default "Desktop," let's say to "Documents" or "Pictures," the process fails, the open window crashes (closes), and the message shared in the attached screenshot below is displayed: "The Windows file-dialog has crashed. No file or folder could be selected."

I thought that the last update to the browser, which was received about a week or so ago, will solve the problem, but it has not.

For the record, I have run all the diagnostics and optimization software (Command Prompt types, and manufacturer software types) to no avail: all report that there are no issues with the OS. Moreover, I only have this issue with Firefox.

Last but not least, on a parallel issue: for decades I've shared feedback on the crappy spellchecker. You have integrated AI in your software, but still offer a crappy rigid spellchecker. For the love of all that is holy, can't y'all fix that problem?! I'm sure that your AI can do that job!

Thanks in advance. I look forward to your rely with the solutions.

Cześć Problem polega na tym że Firefox nie potrafi przejść do końca logowanie do różnych stron przez Google . Pojawia się ekran wyboru konta idziemy dalej a nagle Firefox się zawiesza. To samo na Chrome działa bez p problemu. Jest to uciążliwe.

Sometimes several times in a row.

And it's getting tiresome.

I have the same setup on several machines and only one machine will crash frequently.

Hello, I run Firefox mobile on a Motorola g stylus 5g, and although I'm aware it's a lower-end device, the constant crashes with the app is becoming infuriating. I'm on the newest version, and a large majority of these crashes occur when I'm on twitter browsing posts.

These crashes can happen a few minutes into browsing to an hour, and this issue used to never happen until the update before this one. I use a few extensions related to appearance, those being Ublock origin, dark reader, and control panel for twitter. Performance regarding being on the website has always been awful, but it's never crashed before.

In addition, the app is insistent on reverting me to tabs I had either an few hours ago to days ago, and it changes to what I currently had on screen for unexplainable reasons. I've tried resyncing tabs but this rarely solves the issue

Any advice in resolving these crashes would be appreciated. Attached is my crash log.

I cannot get Thunderbird to launch. It acts like it is stuck on perhaps one account and circles keep spinning as if it never can get a few of my tabbed emails open. It keeps saying it "isn't responding." Since this began happening a few days ago, I've stopped the Thunderbird task through Task Manager, I've shutdown and restarted my whole system multiple times, I've updated to the latest Windows platform and made sure my drivers were all up to date... I can't update my thunderbird (if required) because I can't get in in the first place. I have hundreds of emails in multiple accounts under my current Thunderbird. I can't afford to lose all that history. I don't know which version I'm using because, again, I can't get the desktop app to launch. What do I do?

My email on Thunderbird no longer loads on my laptop. It's fine on my desktop. It just stays a blank screen. "No message found" it says. I have to shut it down and when I do it says "Thunderbird is not responding." Can you give me a step-by-step on how to fix this?

Hello, I sent my new Asus laptop back for repair (via Curry's) as it had lost all sound. When it was returned they had stripped it down including removing my Firefox browser. I have reinstalled the Firefox browser, but everything I try to look at or click on just crashes (Gah! tab has crashed) and cannot be restored. So, apart from reporting this problem here now, I have been unable to access any website or page using the Firefox browser. I am not very tech savvy, so I would appreciate an answer that doesn't assume I have lots of prior technical knowledge (please spell it out for the technophobe!). Thank you to whoever can tell me what I have done wrong, or still need to do to fix this. Helen.

I’ve tried restarting my phone, closing everything out, updating my phone etc, and the crashing keeps happening. It occurs on different webpages, in different places etc, and I can’t figure out how to stop it. It only started after I downloaded the latest update.

Hi,

I use Thunderbird for Android, version 24.0. It downloads emails and attachments just fine, but whenever I try to use it for more than about three minutes, it will crash and say "Thunderbird is not responding", and I get sent back to the main screen.

I have Android version 16, One UI 8.5. How can I share my logs with you? Thanks.

Lately Firefox keeps crashing on my iPhone, iOS 26.6.2

When I re-open it, all my open tabs reappear but all data entries on the webpage I was last on are gone.

This is only happening on my iPhone, not other devices.

Ever since the most recent update the app keeps crashing and also causes my phone to heat up and use more battery. This never happened until recently. I’m the type to have a lot of tabs open on my phone but it’s always been fine until now.

After 5 minutes of the app being open on my IPhone firefox just closes and I get sent to the homescreen I've tried reinstalling, clearing the cache, logging out of my Mozilla account, everything and it just keeps closing. It's really annoying because whenever I reopen the browser my tab refreshes and I lose all the progress on what I was doing.

My iphone Firefox browser app keeps crashing. I have updated the app to latest 158.1, including now having latest operating system on iPhone 16 27.0.1 but still just crashes without any notice.
