Diễn đàn hỗ trợ Firefox

Hello:

I'm not certain if this question comes under Firefox or not:

How do you stop a specific computer software program-app pop-up notification (popping out from the lower right corner of your computer)?

As an example, I have a utility program, IOBIT Malware System Care that pops-up various notifications such as "update notice," "renew," "discount sale" or whatever notice or ads that is 'pushed'.

-I went to my Windows 11 list of installed app "notifications" and this program is not listed. -I tried contacting tech support but they haven't responded. -I went to Firefox 'Settings' -> Privacy & Security->Permissions and then I opened up 'Exceptions' to see if I can block something. It wants me to put in a specific website. The issue is not a website but coming within a software / app program.

So how and where do I stop a "pushed' notification? I assume it's coming in via my browser / Firefox?

Thank you in advance,

Steven

Application error: a client-side exception has occurred while loading (see the browser console for more information).

where is the browser console? how do i fix it never had an issue with until the last two days?

Why it disappeared? It was always there. I am logged in Pocket and tried to restart Firefox. Maybe it has to something do with recently added AI side panel? It seems that since then my Pocket icon is missing. Browser version: 140.0.2 (64-bit) OS: Linux Mint MATE 21.3 (Virginia) Kernel: 5.15.0-143-generic

I joined a Microsoft Teams meeting through Firefox on the web on a Linux machine. When I tried to share my entire screen, I was asked if I wanted to share the entire screen in a Firefox pop up which I said yes. Then the "you are sharing your entire screen" came up, the sharing icon was red and the "stop sharing" button was red. See attached image. This all disappeared and reverted to the default state almost instantly.

Teams has a feature to "manage what attendees see manage what attendees see" where the meeting host can preview shared content before making it live.

I am concerned that the meeting owner was able to see my entire shared screen without me even knowing it through this preview.

Can someone help? Microsoft just sends you around in circles and I can't contact Mozilla.

Like the title says.

I used to have a Pocket icon. Yes, I know it's going away.

I'd like to use the TenTabs icon. Where is it?

And if you tell me it's on the "Customize Toolbar", I can tell you that, no, it is not.

Help?

idk when exactly this nonsense happen or with which update but thats outrageous.

why the hell it canceled in my setting the check mark at startup for opening previous tabs?! i haven't touched the settings in ages since i set them up so it had to be one of your stupid updates.

fortunatly chatgpt had a solution to bring all my tabs back otherwise i'd fucking rage out.

i'v been using firefox for ages but after this i was really thinking i should switch to something else.

I am using Firefox v140.0.1 Snap on Kubuntu 25.04, Kernel 6.14. Since the Firefox update in the past couple days, the mouse cursor has started appearing huge and slightly blurry (as though the image is scaled up) in Firefox and nowhere else. The size is visually annoying, and occasionally difficult to know exactly where I'm clicking (trying to move the caret in a text box for example). It also appears to be a different style from the main desktop cursor, the shape and color are ever so slightly different, but this may already have been the case and I simply didn't notice because of the previously small size. Firefox doesn't have its own built in cursor settings that I can find, nor obey the system cursor settings. I have a high DPI display so perhaps it is being over-compensated for? e.g. both the system and Firefox are scaling the cursor up, assuming the other hasn't done it already, resulting in a cursor that's too big.

Using iOS on Mac Mini desktop, I get no sound on democracynow.org but on the iPhone the sound works fine. Most other streams/videos have fine sound but not imdb.com on the desktop with iOS but again, fine on the iPhone.

I'm having huge memory problems with Firefox. In about:performance I can see that the extensions process takes up way too much memory. When I start Firefox it usually shows a memory usage of around 180MB. However, at some point the memory usage of the extensions process starts to increase and it doesn't stop increasing until my RAM is full and then it increases even further. It increases until I restart Firefox or until it uses so much RAM that my computer runs incredibly slow.

Below you can see a screenshot of the Task Manager showing how much RAM is available on my computer and a screenshot of the about:performance page showing the memory usage of the Extensions process. The RAM available on my laptop is 10GB (the default configuration was 4GB of soldered RAM plus 4GB of exchangeable RAM. I have upgraded from 4+4GB to 4+8GB but 2GB of the soldered RAM on this laptop are used as GPU memory so the remaining RAM is 10GB). The about:performance screenshot shows a memory usage of 13GB for the extensions process which is possible because Windows automatically pages RAM on the SSD when I'm running low on available physical memory. This enables programs to actually use more memory than the available physical RAM but of course programs become incredibly slow when the RAM is full and huge parts of memory have to be paged on the SSD.

My actual question: How can I find the cause of these memory problems?

What I've tried so far

- I have created a memory report on about:memory. The result is at the bottom of this post. - I have watched the about:performance page and tried to find out what action triggers the memory usage of the extensions process to increase. At the start of the browsing session the memory usage is only at around 180MB. It stays like that for a while. At some point it starts to steadily increase by many GBs. But I couldn't find the cause. I don't know what triggers the extensions process to increase memory usage. - I could simply disable extensions and see if the problem gets solved. But I want to know which exact extension causes this problem. It is very difficult to find out which one it is because I have many extensions and I don't know what causes the memory usage to increase. So I would have to disable extensions one by one and wait for an indefinite amount of time and check whether memory usage stays low. But I don't know how long I have to wait until the memory usage would increase because I couldn't identify what triggers it to increase.

Rather than just using trial and error I would like to find a way to use debugging tools to exactly determine what causes the problem.

This (https://pastebin.com/U3QXTAt9) is the memory report from about:memory. This contains the whole extension (pid 18332) section (copy & pasted by selecting the text on the about:memory page). I have left out the rest because I don't know if it contains private data. Please note: this is not taken from the same browsing session as the screenshot that shows a memory usage of 13GB. Why? Because programs run very slow when memory is low and large parts of memory are being paged. The debug tools usually require a lot of RAM and CPU performance so it's very difficult to use the debug tools when the memory is already full and programs are already running slow. This memory report shows a very high memory usage of the extensions process. In this case it's "only" 3.5GB but it was taken in an early stage of the increasing memory usage. As shown in the screenshot below, memory usage can go even higher than the available physical RAM on my computer. The memory report doesn't clearly show which extension is responsible for the high memory usage. In the memory report, I can only see a high memory usage for the items gc-buffers and gc-heap which leads me to think that the memory problem has something to do with the garbage collector. However, I cannot see which extension is responsible for this. No item in this list with a description that identifies a specific extension has a high memory usage. This is only an excerpt from the memory report (only the extension section). I went through the whole memory report with Ctrl + F "moz-extension" and looked for items with a high memory usage but I didn't find a single item with high memory usage that belongs to a specific extension.

After upgrading my 128 esr to 140 esr, some sites stopped opening. In regular versions, it has not opened for a long time. There are many such sites, for example, qwen3.app or temp-mail.io. It thinks for a long time and finally a message that the time has expired. Chromium is ok.

When using any Microsoft 365 product on the browser I keep getting a prompt to "Please sign in" although I am already signed in. I can click the Sign in button and a about:blank page pops up for a split second. Then within a half hour or so, it will pop up again. I deleted my cookies but the problem still persists. Does not happen on other browsers.

I wanted to completely disable TLS 1.3 when using Firefox, so I set security.tls.version.max to 3 (which corresponds to TLS 1.2). That worked up until I got version 140.0.4 installed - now it completely ignores this setting no matter what I set. I tried using cloudflare-ech.com website for test and it confirms that my browser uses TLS 1.3 with ECH. I also tried modifying security.tls.version.fallback-limit to 0 and security.tls.version.min to 0 to get a possible range of TLS 1.0-1.2, but it still uses TLS 1.3.

I suspect Firefox Relay is not allowing me to sign into a site on the internet. Following instructions I put the Relay Dashboard in my Firefox Settings or so I thought. How do I locate it?
