Earlier, when I activated the search field with the Ctrl + K key combination, it was possible to go far back, by rolling back to the previous words (characters). After the update, it almost stopped working. I press Ctrl + Z and nothing happens. As if the browser "forgot" which characters were entered earlier. I haven't made any changes to the settings after the update. Help.

I am running Firefox 94.0 in a couple of Linux Mint systems.

My main desktop computer, with a 3.8 GHz 6-core AMD Ryzen 5 processor on an MSI B450-A PRO MAX MB with 16 GB RAM, has had Linux Mint 19.3 installed for over a year. Just today, Firefox, which has also been installed in this OS for a long time, exhibited extreme slowness. I did an online search, and found that the slowness was cured by using the Troubleshoot Mode, but none of the suggestions I found solved the problem in normal mode. So, I went into Settings and turned off hardware acceleration. That solved the problem, somewhat ironically. The hardware acceleration seemed to accomplish deceleration instead. So my browser works, but there is something wrong with hardware acceleration in Firefox.

On a new install of Linux Mint 20.04, I recently experienced frequent crashing of Firefox just after clicking on a link. I tried online solutions, which didn't help, but then I turned off - - guess what - - hardware acceleration, and no more crashes. That is what motivated me to turn off hardware acceleration in Firefox on my Linux Mint 19.3 machine today.

I don't really have a problem to solve, but I don't know of a better place to submit a bug report, so I am hoping you will pass this on to the developers.

Can you explain why the desktop and laptop are different both using Firefox and how can I remove the problem on the desktop.

Hi, i'm using Thunderbird 91.3.2 (64-Bit) on Windows 10 and was quite happy up to last Monday (15.11.21). Since then i can't send Mails anymore. When i create a new Mail the send button is un-greyed as soon as i enter a valid reveicer address. But when i click on "Send", nothing happens. The mail-window stays open, no error message, no other reaction. To narrow down the arrow i deleted an SMTP server (not used anymore) and created a new one (server of a friend of mine, so i know for sure it's reachable and all data is correct). In the compose mail window i still see the old (deleted) SMPT server and the new one is not there. In the SMTP server setting window under "accounts" the list is correct (old one removed, new one is there). So somehow the server settings seem to not get refreshed or anything.

Receiving mail works without any problems. I'm not using a proxy, firewall or anything else that could mess with my connection, but i also think the problem is not with the connection.

Things i have tried already and that did not help: Run Thunderbird with Administrator rights. Try to update thunderbird (the "about" menu states that i have the most recent version). Restart in safe mode. Copy my profile folder and load that copy.

The only plugin i have installed is "provider for google calendar".

One more error I get, that might be related: When i reply to a mail the "send" button stays greyed out until i clear the whole receiver input field and enter a new addres (can be the same as the one i deleted immideatly before). After that the button is un-greyed but clicking on it has no effect, just as with a newly created mail.

Is that a known bug, what additional information should i provide and what can i do against it?

I'm using a german version of Thunderbird so please excuse if some of the buttons or menues are named differently than i tried to describe here.

Since the most recent update Firefox is constantly freezes at random times. It happened during visiting my bank site, reading an article on NPR site, opening an email, etc. None of the freezes happened during start up, but the showed up at various times some within 10 minutes of browsing time. some after 3 hours of browsing.

Hello all, I got just installed the new last update 91.3.1 version and now the area of email body text has become all black "magically". With last update of W10 it's not anymore possible to set Dark for system and Light for apps so I wonder how can I come back to my standard Thunderbird background. I read many complaints about this . Also setting the TB theme to light it doesn't work. Please fix this bug or make a new theme where the email body background remain white . I don't understand why using TB from tens years during last times there are so many strange behaviors and why so many update in short times. Thanks

Hello there

I have a small NAS with various video files on it. Some AVI which work flawless but also some MOV which show but do not play audio.

Other chromium based Browsers manage to do so without any problems therefore it should be possible somehow.

Informations regarding the file: Filetype: MOV Codec: MP4 Base w/ AVC ext (ISO 144496-12:2005) Channels: 2 compressor: sowt Sample rate: 48khz Depth: 24bit Bit rate: 16

It was recorded with a Nikon D3200 camera.

As I am hosting these Files for other people I always get requests on why it does not work in Firefox.

I love Firefox and I want People to use it but such things just make in unnecessarly hard to do so.

I have experienced great business support from the Mozilla team, hope this to be true for home users too.

Thanks beforehand and have a nice evening.

Hi, I developed a simple Add-on, based on jQuery. Unfortzunately, it seems "ajaxStop()" does consistently not work as expected (at all). Any tips on what to consider to get ajaxStop to succesfully trigger my registered eventhandlers? Thanks

PS off topic: the "developer" area of Mozilla is quite painful to handle and reach. I'm always pushed/forwarded back over here. Also the sophisticated 2way-auth seems a bit overkill for posting on a forum .

I have tried everything and cannot manage to load any webpage that prompts a reCAPTCHA. The tab immediately crashes.

1- I've tried several webpages. They all work well until a reCAPTCHA pops up, the tab crashes and creates a dump file 2- I tried uninstalling Firefox, including erasing profiles and all Mozilla folders then reinstalling, and selecting refresh. It sill happens. No addons or extensions, and HW acceleration on and off 3- The problems goes away if I run Firefox on Troubleshooting Mode

Version is 94.0.2 (64 bit) running on Windows 10 21H1 on an i7 1165G7

Am I missing something? Is there a way to do a cleaner install?

Thanks for the help!

I reconetly bought a lifetime service with Adguard. I have it both on my PC/Windows 11 and Android (Pixel 4a 5g). The issue — Firefox for Android will not work with it. Please help. Thanks.

Hello. Today I did the update to 91.3.2 (32 bit). I have a ton of message filters where attachments get forwarded. I have been getting multiple error messages "Sending of the message failed. There was an error attaching 7BE18B4040EA34BD50E540A4B47F5A7A_graph0.png. Please check that you have access to the file." on some but not all of my emails. What do I do? Thank you.

I have a lot of tabs open and when I start firefox the welcome page is placed as the last tab. I always have to search where I left off. Please open these pages next to the last used tab. The only other solution I have is to disable this stuff
