Hello,

I've noticed that recently that Firefox seems to repeatedly crash on my Xiaomi phone quite frequently. It's a Xiaomi 15 Pro on HyperOS 3.0.7.0, and here are some of the crash reports:

Hello all.

I'm running into frequent tab crashes, very commonly on pages that have a lot of elements, or things to render on the page.

Specifically, I am being challenged by gmail, where switching to my inbox will 100% crash my tab.

Here are a few crash reports to look at from this gmail example. It is not gmail alone that causes this, other websites such as Zillow, youtube, etc. Pages that contain a lot of information and pictures typically cause this.

https://crash-stats.mozilla.org/report/index/d4965ad5-0592-4b0a-bc67-4e8080260328#tab-details https://crash-stats.mozilla.org/report/index/f48490e0-6aaf-423c-80a1-e2aaf0260328#tab-details

I also want to mention that I have the exact same profile loaded onto another machine, and I experience no issues. I do not believe this is an extension issue, but I am open to disabling all of them and generating more crash reports if anyone would like for me to try that.

What stuns me the most in these crash reports is the reported amount of "available virtual memory" exceeding far beyond what I have available on my machine. Can anyone help pinpoint what about my system would keep making Firefox think I have this much available virtual memory?

Thanks for any advice and help!

After new update my Firefox is completely bricked. I can't do anything with it, it just wiped all of my tabs out and now I can't open any, search or do anything.

All my settings are blank, running private doesn't help. If I right click a tab, it shows up with "new" and all of the other opens are blank.

It first happened after the update, only my first and last tab had titles. All the other tabs open turned blank, and could not be accessed. Then the second time I accessed them, they had all disappeared.

Tried reinstalling, didn't help.

On desktop, but had to make this on mobile because I can't even get to the support website.

My firefox has been closing while I am away from my computers. I have a few computer running linux (Ubuntu 24.04) and one in mac osx (Big Sur). Usually, I can start firefox and it will remember my tabs which is annoying but still manageable. However, once in a while, (which happened yesterday), all the firefox closed on all the computers and it forgot my tabs when I start firefox again.

I have already set app.update.auto to false on all of the firefox instance prior to this incident to avoid firefox update would close out firefox itself. So if anyone has any idea of what to check to see why firefox keep closing and/or why once in a while it will not remember my tabs, I would really appreciate it.

After Windows installed an update in the middle of the night I can't open Thunderbird and I've tried uninstalling it and reinstalling with success.

It says: Thunderbird is already running, but is not responding. The old Thunderbird process must be closed to open a new window.

I've rebooted the PC, shut down the PC, ended the task and still nothing. It seem that Thunderbird didn't shut down correctly and the system still thinks that it's open and running. Anyone know how I can fix this issue?

Thanks,

Gregg

Hello,

I would like to report a potential bug in Mozilla Firefox related to recent updates.

After downloading a PDF file and opening it directly in the browser, the tab crashes. Following this crash, it becomes impossible to open any files (regardless of file type) within the browser — every attempt results in another tab crash. The crash report cannot be reviewed, as the tab fails immediately and can only be closed.

As a temporary workaround, changing the default PDF handler to an external application prevents the issue. However, this is not a viable solution for us, since some of our internal systems require PDFs to open directly in the browser after download.

We have verified that this issue does NOT occur in version 148.0.2 — everything works correctly there. However, after updating to version 149.0, the problem reappears consistently. Firefox also automatically updates after synchronization, making it difficult to remain on a stable version.

According to the release notes, there were changes in PDF handling in recent updates, so this may be related to a technical regression.

Could you please investigate this issue or advise on a proper fix or workaround?

All firefox windows just disappear after a random amount of time. Where can I look for possible logs of what's happening. Didn't see anything obvious in Event Viewer>

I get the message: We're Sorry Firfox had a problem and crashed. We'll try to restore your tabs and windows. To help us diagnose and fix this problem, you can send us a crash report. I sent the crash report multiple times.

I added a screenshot of my MacBook Air info.

Moderator note: This question has been edited to fill the Firefox version field (based on the info submitted).

Program is freezing after a few minutes, even without using, Tried repairing all the folders and everything I could find on google, installed on another laptop, But still the same.

Can you please help me ? Why does my Thunderbird email account keep crashing upon startup ? It comes up everytime and after 1 minute it crashes . I receive email but only if it is that 1 minute time frame . It just started yesterday , 3/23/2026.

I use K9mail on multiple devices since eternity. Since the latest update it crashes on an old Galaxy S10 / Android 8 when fetching images (show remote images) or, it looks like, when the message has images.

It crashes on 80% of mails with image. I can provide you with messages that reliably crash (e.g. newspaper newsletter from nzz.ch) and with only one that works (newspaper newsletter from 20minutes.ch) Plain text and plain HTML text messages seem to work fine.

it works fine on all other [android 12+] devices Re-install the current version did not help re-installing an older version from FDROID worked

Help is apprechiated

I was using TB like normally on windows 11 when it crashed. Now every time i try to open the app it prompts me to send in a crash report, but every time i press "restart thunderbird" a new window with crash report shows up. I have tried writing a comment, checking and unchecking all the boxes and pressing quit thunderbird. But i still get sent into the loop.

For about 2 weeks, EVERY time I try to write an email, after typing a few lines or so, the whole window 'grays out' and becomes UN-responsive. I get no error message. Waiting for it to respond doesn't work and I have to close out and re-start Thunderbird. Sometimes Thunderbird will have saved some portion of my email in my 'Drafts' folder, but not reliably, so I have to frequently 'Control + S' - save it to avoid having to re-type the entire message again. Troubleshoot Mode doesn't help, nor does clearing the cache. I've been hoping an update would come up that would solve this, either from Thunderbird or Windows (11), but not so far. Please tell me how I should resolve this - I have used Thunderbird for years (and regularly contribute too) and don't want to have to change to different email client.

Hi.

I have recently set firefox as my default browser on my Google pixel 8a.

I have had to clear all data from my Firefox browser twice in 2 days. First time I didn't know what was going on and saw in a search that when your browser stops loading try clearing all data, and it worked.

Second time was when opening a link from a Google pixel email about new features: Google pixel new feature link .

When it happens no page will load, the tab just remains as a black screen. This happens to all tabs that were previously opened as well as the new tab from the link.

I don't know if this is because of links from Google mailshots, or links opened from Gmail (don't think so), or what, but having to clear all data daily is a big issue. History, logins, cache, etc, lost.

It definitely need a fix please.

I've got constant crashes jn last update Firefox 148.0.2 (Desktop). Often it happens when Google Meets launched in browser and i started switch between tabs or another applications.
