My GPU is the integrated GPU on the Intel U7-155H CPU. When some AVC videos are played, the browser reacts extremely slow and the video image is glitched and at a really low rate of frame, and the video decoding engine seemed to be 100% occupied as shown in the task manager (normal video playback never occupied so much of it). Seems like AV1 encoded video never triggered the problem. The problem doesn't always happen, but at a rather high frequency. This never happened before I updated the Intel graphics driver from 32.0.101.5972 to 32.0.101.6129. The problem seemed not to happen on other browsers such as Microsoft Edge.

When using a traditional 3-button navigation bar for my system UI, I can long-press the "back" button to call up the current tab's history, allowing me to navigate back or forward several steps at once. However, when using gesture navigation at the system level, there no longer is a back button to hold. How do I open the individual history in that case?

Hello, I'm currently using a Macbook Air, Early 2014, that still works perfectly fine for my needs. But it runs with OS X 10.9.5 and Firefox 78.15.0esr, that unfortunately can no longer be updated. That wouldn't be a problem to me since I do a very limited use of the computer, but now I'm getting the message "Your Firefox may start to have problems on January 14, 2025 since updates are not available for this OS". What should I do if I still want to use this device with Firefox to browse the internet? If it is impossible to keep using Firefox, any suggestions for an alternative browser that may still work? Safari is no longer an option. Thanks a lot for any and all replies

Good day, everyone,

I've been using Firefox for several months since switching over when the migration to Manifest V3 in Chrome gained momentum. Initially, Firefox worked flawlessly, but over the past couple of months I've encountered a recurring issue where downloads often fail -- sometimes right at the start and other times midway through -- especially with larger files.

I've encountered this issue across multiple machines, and changing the destination drive where the files are saved hasn't made any difference. Interestingly, the same files download without any issues in Chrome, so I've ended up relying on Chrome exclusively for downloads.

Has anyone else experienced this issue?

Thanks in advance!

As title, MS defender keeps detecting trojans everytime firefox is launched and while I'm pretty sure it's probably just a false positive its just getting rather frustrating and now more so, worrying that it's constantly happening.

I have a calendar with a CalDAV connection through my hosting service. The CalDAV connection is fine, because it is working properly on my phone. However, when I try and add the calendar in Thunderbird I run into problems.

I have managed to create the calendar and Thunderbird did accept my login credentials. The calendar appears in the calendar menu, but it is not enabled. When I try and enable it, it immediately jumps back to "not enabled". What could be causing this, and how do I get around it?

Thank you sincerely, Rasmus

For many years I have enjoyed using Mozilla Firefox Web Browser and Mozilla Thunderbird email client. Apart from the occasional glitch, everything has run well until I installed the latest Thunderbird Version 128.1 esr, earlier this month. I had used Message Filters to move inbox emails directly into my Local Folders. Now there is no option to either create a new folder or create a new sub folder. I tried to convert a little used Local Folder, and lost the sub folders. I don't know where they went and cannot restore them. Q1. I just do not understand how to use this new version. Do Mozilla have an instruction manual for using the V128.1 esr? How do I alter the previous version installation to be compatible with this one? Q 2. If, for the time being, I would like to stick with the familiar previous version, how do I do that? Mozilla are convinced V128.1 esr is a big step forward. I need your help to convince me to change and how to do it. Regards, Colin
