I am experiencing significant stability issues with Firefox. When I use YouTube, the entire browser frequently hangs (becomes unresponsive) and eventually crashes. This does not happen on all websites, but it is consistent when playing video content on YouTube.

• Symptoms: The browser "stacks" or freezes completely; I cannot click tabs or menus until the browser finally closes/crashes.

• Extensions: I am currently using extensions like SponsorBlock, uBlock origin. I am unsure if this is the cause, but the issue persists during video playback.

• Hardware: I am running this on a laptop with an 16gb 4800mhz RAM, i7 12th Gen processor and an RTX 3070 GPU.

1. Is there a known compatibility issue between current Firefox builds and SponsorBlock or similar video-modifying extensions?

1. Could this be related to hardware acceleration settings with my NVIDIA GPU?

1. What steps should I take to provide crash logs to help identify the root cause?

Hello,

This problem has been occurring for several weeks.

"The certificate for imap.gmail.com:993 is not from a trusted source."

This problem only occurs on my computer running Windows 11. There are no problems on my mobile phone.

Thank you in advance for your reply.

I have two different email accounts in Thunderbird. One is a Gmail account one is from Comcast.net. When I start Thunderbird it checks Gmail fine, but then I get a little pop up in the lower left-hand corner it says Comcast has blacklisted my IP. After a few more seconds a dialogue box pops up asking for my password. When I type in my password I get the same crap over and over.

I know my IP is not blacklisted because I can log on to my Comcast account in a browser no problem same IP. What's going on, do you think I picked up some sort of malware? I've scanned I can't find anything.

Went to do something on a website, saw that I had been logged out, went to log in and it didn't auto-fill. Went to check the password but seemingly it isn't saved anymore.

The problem lies in the fact that I signed up with an email mask, used a random password and I can't get a recovery email sent to it. So am I perma locked out forever?

I'm just confused on how the saved password can disappear? Any help?

I've been having this strange behaviour in Firefox Nightly on Android, where the "Delete browsing data on Quit" setting, whether it is ticked or not, automatically closes open tabs. This used to not be a thing, and I wish for some clarification if this was supposed to do this from the start or not.

My settings under the "Delete browsing data on quit", which is of course turned on: Ticked: Browsing data, Cached images and files, Downloads Unticked: Open tabs, Cookies and site data, Site permissions

Tabs get closed, otherwise works as on tin.

I read magazines using PressReader on Firefox but during this the window keeps getting refreshed. When this happens I end up back at the beginning of the magazine instead of on the page I'm reading. It's becoming almost impossible to read the entire magazine.

What I can't work out is what is doing this? Is there a Firefox setting that I need to change?

There seems to be no settings in PressReader.

I'm running Firefox on Win 11 Pro if that is relevant.

As of recently, I have problems with Firefox that do not happen in other browsers. But Firefox is my favorite, and I'd like to have this solved so I can keep using it.

In Zendesk, there is an option "Print ticket" which should open Print dialog and we then can print whole email to PDF. This worked for years, but as of recently that dialog simply does not show. I tried change Firefox settings for printing, but problem remains. Attached is a screenshot how it looks in chrome, and how it used to work in firefox.

As from yesterday, April 17, Firefox will not load correctly https://m365.cloud.microsoft page. It loads, but no element reacts when clicked. I cleared cache, cookies, removed extensions, refreshed firefox, but to no avail.

Thanks for the help!

Hi. I use Thunderbird Android 17.0 on my phone and tablet. Everything is great on the phone.

On the tablet, unified inbox worked fine until two days ago. Now, no email goes into the unified inbox and I have to open accounts individually to see email. The unified inbox still shows, but the last email in there is from two days ago. I did not change any settings and berichten that the checkbox is checked to show the unify inbox.

What cohort have caused this and how can I fix it?

Hello All,

I'm using Firefox (149.0.2 snap) with LUbuntu 24.04.4 LTS. Because of a wrong graphic driver, I had to turn off hardware acceleration in FF.

When FF is started the Initial "Firefox - Choose User Profile" is unreadable (see attached : wrong_screen.jpg), but if I continue (click somewhere in the window) , all the opened tabs are readable.

Once in FF, if I want to select another profile from the application menu -> .. -> manage profiles, then the "Choose User Profile" window is fine (see attached : good_screen.jpg).

I tried to start FF with the "-P" option to specify wanted profile but it continues to start with the unreadable "Choose User Profile" window.

Could someone give me a solution, except finding the good hardware driver for my computer?

Thanks Bouilla.

On the new tab page I have set for 4 rows of shortcuts. In the fourth row I have 3 open spaces for tiles/shortcuts. There is no way to add the tiles whereas there was previously a tile that would show that said "+add shortcut". Given I have room in the row to add 3 shortcuts, how do I add tiles to allow for added shortcuts?

Hi, The goal is download attachments from a RSS feed. I set a specific folder so i don't have to select path for every single file. Then clicking on the file link and it should start to download but it is very unreliable especially when used on many files in sequence it silently fails. Related big problem is absence on any useful file transfer indicator like Firefox has. There is a "download manager" tab but it is completely useless. It does not show any progress and the view has no scroll bar so nothing useful can actually be seen there. Downloading using "save as" button works. So you should either fix the direct link download or disable the feature completely until it does work, to avid missing files, because that is the worst outcome.

When I try to sign in from Firefox I get the message "Unexpected error". I can sign into my account online but only using Google to sign in. If I try to sign in to Mozilla directly, I get the same message.

The Cache is never cleared after clearing, there are always about 9,3 MB left. According to my settings there should be 0 MB left. (When I check the Task Manager, Firefox ist always opened up to 10 times.) How can I make sure the Cache is completely cleared? I added Screenshots of both. Thnx for helping...

hi all. if i create a new blank Task it automatically pre-selects today's date as the start date, and if i create a Task from an email it sets the date the email was received as the start date. i know can filter tasks lists, and hide columns, but the real issue is how it looks on the calendar; with the fixed start date, setting a due date in a month's time results in a fixed, ongoing task for a month. is there any plugin or setting that will just stop TB setting a start date that i can't change, or letting me explicitly set it myself?

I need help with annoying pop-ups. I followed instructing. It only say allow, not block, when I go to settings, security & privacy, checked block pop-ups and third party redirects.
