Diễn đàn hỗ trợ Firefox

I like to use picture-in-picture mode to watch a YouTube video in the corner of my screen while editing an image or playing an online game (since I like having something to keep my brain active while I'm doing something). Recently, however, this has resulted in my computer locking up. I don't really know how to describe it succinctly, but audio becomes super stuttery and it takes a second or more to render a single frame. Last night this resulted in the loss of an in-progress image (don't worry, I took photos of my screen so I could recreate the image), so I want to figure out how to stop this.

Just to cover my bases, here's my specs:

Windows10 simply multiplies the numbers of active Mozilla Firefox Apps which are open. Every day for about two weeks I've been having to delete hundreds of Firefox Apps open in the Task Manager. So many open in a very short time it locks up the Win10 system. I've attached a pic

Win10 will no longer let me download & transmit a .jpg file, sorry

I have been with Firefox since Netscape Navigator so I understand how it works. I have a Bulletin Board Forum (work on it daily). Posting to the forum using long form bbcode is very time consuming and tedious.

I've been using bbCode for Web Extensions (bbCodeWebEx) (https://addons.mozilla.org/en-US/firefox/addon/bbcodewebex/) for years and up until the recent Firefox update it has worked perfectly.

Matthew G. Saroff (https://addons.mozilla.org/en-US/firefox/user/96273/) was the developer of the extension.

I have tried using the extension on multiple sites. The extension is there and functional but nothing registers in the edit windows. not even here.... I've looked for replacement extensions but none have the specific abilities I need for posting on my forum. Specifically- The ability to select an img coded image address and make it link to a specific webpage url. Other common bbcode can be tagged using the edit window's fully enabled wysiwyg editor.

I'm not sure if other extensions are having issues with this release but the rest of my extensions function normally. Something changed which blocks the paste functionality of the coded clipboard text into the edit window. I might be a developer issue but my question to him is, as so far, unanswered.

I tried to install an older version of Firefox, Downloaded the install, created a new profile, uninstalled this version and it worked until I restarted Firefox (with updates set to manual). It automatically updated and I lost it again. I tried using ~about:profiles~ to revert but it reverted as that profile this version. Years ago, I used Waterfox so I could use the Legacy extensions. I stopped using it when I got accustomed to the new extensions. For the past few years, Firefox is the only browser I use. I don't want to have to cut my teeth on a new browser but as the administrator for my forum, I use bbcode everyday.

I am wondering if any other Firefox users are having issues with the recent update? Thank you for reading my concerns.

bold text all my passwords seem to have disappered on my desktop, I checked my mobie app and they were there. there was a message to sync this morning on sign in.

My Firefox shortcuts keep disappearing: this is an almost daily occurrence. Sometimes they re-appear later without any intervention, sometimes they re-appear after a reboot. Right now, after rebooting and 'fixing' Firefox from Control Panel, they are still missing. I have 4 rows configured for both shortcuts and recent sites, and had 'pinned' about 20 shortcuts. Currently on Windows 10, soon to upgrade to Windows 11.

Can someone PLEASE tell me if there is a fix available for this (will it be resolved in Win 11?), or if there is a way to easily save and restore these backups when this problem occurs.

The ability to have 32 shortcuts is the motivating reason for my using Firefox over Chrome or Edge (which only allow 8), but if they keep disappearing like this I'm going to have to re-think my browser selection.

Thanks for any suggestions.

Why can't Firefox open .mht email extensions within its default browser? It has never done so to my knowledge. They always point to Internet Explorer or Microsoft Edge.

Often an email may not display images correctly and the ability to open them in a web browser is offered, "If there are problems with how this message is displayed, click here to view it in a web browser." This is certainly a development addition when people view their Gmail from Firefox or use Outlook. Not everybody uses APPS. People who don't want Microsoft Edge watching every move they make have made effective permanent changes in removing the deep embedded PUP by Microsoft.

Firefox version: 148.0

I have three failed downloads that are stuck on the list. Retrying them does nothing, and deleting them does nothing.

Incidentally, the images that those failed downloads link to are online and available.

How do I get rid of them?

Not sure but I read that windows 10 has reached the end of support in oct. 2025. I have no idea what book marks I had because My friend put them in for me. I do not know why firefox or windows had the rights to chage my computer and I do not have the funds to buy a new windows 11 computer. So bottom line what can I do to fix this issue

Many websites that I use regularly, such as Zillow, no longer work correctly in Firefox ESR (115.33.0). The top menu in Zillow disappeared this week. Others work, but all the text is greyed-out. All except the text thing seem related to Javascript features. For instance, check boxes on a Wordpress site that I manage quit working last month. Some, like www.RCgroups.com just sit and spin, and never fully open up.

But they all work fine on an old copy of Chrome (109.0.5414.120), that is no longer supported on Windows 7 and hasn't been updated in probably 3 years.

My only plugin is NoScript, but the problem is the same whether it's turned off or not. And I also use NoScript on Chrome.

I use Win7 for the same reason I use Firefox -- it is safer, far more stable, faster, and it doesn't force updates on me that invariably break things. I appreciate that Mozilla has extended support for the last stable version of Windows. But somebody should look into this growing compatibility issue.

i noticed every websites that i visited or some links just suggested are appeared in my firefox homepage i selected only shortcuts in setting which i expect to see only shortcuts that i added manually but its just more shortcuts pop up each time i open the new window on my home page this is really annoying and , its not necessary at all , i dismissed them manually but they just pop up again please can you report this issue to be fixed on next release ?

thanks for looking into.

Back again with another question related to flightrising

there are familiars displayed next to the dragons, some of them are supposed to change their pose automatically, but for me they only change when I click on the familiar it works on other browsers, and on firefox for windows, so I guess it's something in about:config, but I have no idea what I'm doing, so I'm hoping someone here can help me figure this out, because I'm not about to mess around randomly

link to a page with a familiar that's supposed to change: https://www1.flightrising.com/dragon/80217294

pretty sure it's obvious what I mean by transform, and what I have to click on to get it to move, but I'm posting the pictures illustrating the change anyway

Watching a CNN video on YouTube Firefox suddenly freezes and does not accept any further actions. Even shutting down it will block the process and I need to use the "Shut down anyway" function. Similarly, Thunderbird will lock up in the middle of writing a response, but here it is just the window and I lose what I typed, but I can go back and push "reply" again and retype the answer. Whether these are down to similar issues I don't know. Obviously, this sounds like a graphics driver, so I made sure all updates are installed and there is no further update available for both, Firefox and Thunderbird as well as the system drivers.

Any pointer is appreciated as this is really annoying. Thanks
