Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

I have been getting this error for about a week - absolutelyu no changes have been made to my usual use of the PC and browser. There may have been Firefox/Windows updates installed. I'm not doing anything different to the usual work I do.

I have tried using a new Firefox profile with no cached info carried over, this doesn't solve the problem. I have no extensions or add ons. I do run Avast, but haven't had this problem before.

NB: I do not usually get the opportunity to submit a crash report when these crashes happen.

I requested my Pocket export three times in June '25 and have received nothing. (Most recent request on 24th June '25, ID: 25174602-3e81-421e-a30d-71ff91dd2d66

I have also contacted Mozilla Support using the contact form twice to raise this issue and didn't receive any confirmation of those support requests to my email address.

The only possible explanation that I can think of is that maybe there has been a problem at the time when Mozilla acquired Pocket and I linked my Pocket account with my Mozilla account. I had previously used a different email address for my Pocket account prior to 2017. I currently have two email addresses (primary and secondary) associated with my Mozilla account but none of these email addresses are showing up in my Pocket settings, only my username. My Mozilla account is the only place where I can see my email addresses listed in my account details but I can't understand why I didn't get the confirmation emails to my Mozilla Support requests.

I used Pocket extensively for work so I really need to get the export. I'd really appreciate some help, thank you.

Hi there. I tried to connect to a library WiFi which required to enter a username and password in a login form to have Internet access. First of all, the firefox could not open the login page normally (automatically). I had to check the Gateway IP address of the WiFi connection and find the login page manually (same problem with chrome). But when I tried to submit the login form, I got "Secure connection failed" error in my firefox (PR_END_OF_FILE_ERROR). Then I tried chrome and the form submision worked fine. I experienced this same problem both on Windows 10 and Debian 12 (could not submit the form on firefox, but it worked on chrome), so the network setting misconfiguration scenario is unlikely. I also read the mozilla page related to the error but it was not helpful. What is the problem and how could it be solved?

I imported bookmarks from an html file and when I click on Other Bookmarks I get a Get started message from Lastpass. I don't know what to do next. I am already logged into Lastpass.

The message is: You’re almost done. Next, click the LastPass browser button above to create your account or log in.

I've been using Firefox for many years, and today when trying to open, it froze up and said it was a version that was no longer working.? So I went to firefox.com and downloaded it again onto my Mac desktop. I am logged into my Mozilla account, but none of my info from my account shows up! Where are all my bookmarks, passwords, tabs???? What do I do?

The Youtube screen shows gigantic forms. I tried asking google how to get back it to normal size, but they kept referring me to youtube videos, which obviously don't work since the website itself is the problem. I checked View-Zoom and that did not help either.

Thank you in advance fro any help.

A couple days ago, FireFox started having issues rendering certain websites and using certain websites.

I checked maintenance and loaded a new version. No change.

I turned off blocking and fingerprint settings one-by-one and restarted. No change.

I disabled an extension that was showing an error for requiring something with tabs. No change.

At this point, FireFox is unusable. I'm looking for any ideas to get it working again.

I have tried to clear the cashe, clear cookies, download a new version of Firefox. Nothing seems to work...What is going on with Firefox? I am having terrible problems with it that I've never had before.

Hey, I have a dual monitor setup, whenever I mouse over the sidebar to move to my other monitor the sidebar gets stuck on the expanded state which covers content on the currently open webpage

Is there a way to make the sidebar close when my mouse leaves the monitor?

I have hover to expend enabled, so I would expect it the sidebar to close when my mouse leaves the monitor (as well as the firefox window)

I'll be happy to share any other information related to my question.
